3.1 A number of laboratory procedures are used to evaluate the effectiveness of fire-retardant and fire-resistant treatments and coatings. In general, these methods measure the three stages of fire development: (1) ignition; (2) flame spread (rate of growth of the fire); and (3) conflagration extent. While all three are of extreme importance, flame spread has been recognized as the main factor associated with testing fire-retardant coatings.3.2 Flame spread ratings based upon Test Method E84 have acquired common acceptance by regulatory agencies, but such large-scale tests are seldom practical during the development or modification of a fire-retardant coating.3.3 This test method provides the relative flame spread of experimental coatings using small test specimens under the conditions established in the 2-foot tunnel. By experimentally calibrating the 2-foot tunnel with similar Test Method E84-rated fire-retardant paint, results obtained by this test method can be used to screen coatings for suitability for testing in the Test Method E84 tunnel.3.3.1 This test method is intended as an experimental tool in evaluating experimental coatings for further development. No direct correlation of results from this test method and the Test Method E84 tunnel have been made or are implied.3.3.2 The results obtained by this test method do not in themselves act as an accurate predictor of performance in Test Method E84 and shall not be used for the purpose of certification to any class of flame spread performance.1.1 This test method determines the protection a coating affords its substrate, and the comparative burning characteristics of coatings by evaluating the flame spread over the surface when ignited under controlled conditions in a small tunnel. This establishes a basis for comparing surface-burning characteristics of different coatings without specific consideration of all the end-use parameters that might affect surface-burning characteristics under actual fire conditions.1.2 In addition to the experimental flame spread rate, the weight of panel consumed, time of afterflaming and afterglow, char dimensions and index, and height of intumescence can be measured in this test. However, a relationship should not be presumed among these measurements.1.3 This standard is used to determine certain fire-test responses of materials, products, or assemblies to heat and flame under controlled conditions by using results obtained from fire-test response standards. The results obtained from using this standard do not by themselves constitute measures of fire hazard or fire risk.1.4 The values stated in SI units are to be regarded as the standard. The values given in parentheses are for information only.1.5 This standard is used to measure and describe the response of materials, products, or assemblies to heat and flame under controlled conditions, but does not by itself incorporate all factors required for fire hazard or fire risk assessment of the materials, products, or assemblies under actual fire conditions.1.6  Fire testing is inherently hazardous. Adequate safeguards for personnel and property shall be employed in conducting these tests.1.7 This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety, health, and environmental practices and determine the applicability of regulatory limitations prior to use.1.8 This international standard was developed in accordance with internationally recognized principles on standardization established in the Decision on Principles for the Development of International Standards, Guides and Recommendations issued by the World Trade Organization Technical Barriers to Trade (TBT) Committee.

3.1 The property of color of a solvent varies in importance with the application for which it is intended, the amount of color that can be tolerated being dependent on the color characteristics of the material in which it is used. The paint, varnish, and lacquer solvents, or diluents commercially available on today's market normally have little or no color. The presence or absence of color in such material is an indication of the degree of refinement to which the solvent has been subjected or of the cleanliness of the shipping or storage container in which it is handled, or both.(A) This is platinum-cobalt color No. 10 in Guide D365.3.2 For a number of years the term “water-white” was considered sufficient as a measurement of solvent color. Several expressions for defining “water-white” gradually appeared and it became evident that a more precise color standard was needed. This was accomplished in 1952 with the adoption of Test Method D1209 using the platinum-cobalt scale. This test method is similar to the description given in Standard Methods for the Examination of Water and Waste Water4 and is referred to by many as “APHA Color.” The preparation of these platinum-cobalt color standards was originally described by A. Hazen in the American Chemical Journal5 in which he assigned the number 5 (parts per ten thousand) to his platinum-cobalt stock solution. Subsequently, in their first edition (1905) of Standard Methods for the Examination of Water, the American Public Health Association, using exactly the same concentration of reagents, assigned the color designation 500 (parts per million) which is the same ratio. The parts per million nomenclature is not used since color is not referred directly to a weight relationship. It is therefore recommended that the incorrect term “Hazen Color” should not be used. Also, because it refers primarily to water, the term “APHA Color” is undesirable. The recommended nomenclature for referring to the color of organic liquids is “Platinum-Cobalt Color, Test Method D1209.”3.3 The petroleum industry uses the Saybolt colorimeter Test Method D156 for measuring and defining the color of hydrocarbon solvents; however, this system of color measurement is not commonly employed outside of the petroleum industry. It has been reported by various sources that a Saybolt color of +25 is equivalent to 25 in the platinum-cobalt system or to colors produced by masses of potassium dichromate ranging between 4.8 and 5.6 mg dissolved in 1 L of distilled water. Because of the differences in the spectral characteristics of the several color systems being compared and the subjective manner in which the measurements are made, exact equivalencies are difficult to obtain.1.1 This test method describes a procedure for the visual measurement of the color of essentially light colored liquids (Note 1). It is applicable only to materials in which the color-producing bodies present have light absorption characteristics nearly identical with those of the platinum-cobalt color standards used.NOTE 1: A procedure for estimating color of darker liquids, described for soluble nitrocellulose base solutions, is given in Guide D365.1.2 For purposes of determining conformance of an observed or a calculated value using this test method to relevant specifications, test result(s) shall be rounded off “to the nearest unit” in the last right-hand digit used in expressing the specification limit, in accordance with the rounding-off method of Practice E29.1.3 The values stated in SI units are to be regarded as standard. No other units of measurement are included in this standard.1.4 For specific hazard information, see the Material Safety Data Sheet.1.5 This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety, health, and environmental practices and determine the applicability of regulatory limitations prior to use. For specific hazard statements see Section 6.1.6 This international standard was developed in accordance with internationally recognized principles on standardization established in the Decision on Principles for the Development of International Standards, Guides and Recommendations issued by the World Trade Organization Technical Barriers to Trade (TBT) Committee.

2.1 Color may be indicative of the quality of the solvent because any color present is due to the presence of contaminants.1.1 This test method covers the visual measurement of the color of halogenated organic solvents and their admixtures. It is valid for values of 50 platinum-cobalt (Pt-Co) units or less.1.2 The values stated in SI units are to be regarded as standard. No other units of measurement are included in this standard.1.3 This standard does not purport to address all of the safety concerns, if any, associated with its use.

3.1 Color by this test method is a measure of color-producing impurities present in the thermally stable solids. This test method is suitable for setting specifications and for use as an internal quality control tool.1.1 This test method covers the visual measurement of the color of thermally stable solids melting below 150°C. It is applicable only to materials in which the color-producing bodies present have light absorption characteristics quite similar to those of the standards used. The scope of this method covers the range of calibration which is 0 to 100 Pt-Co color.1.2 In determining the conformance of the test results using this method to applicable specifications, results shall be rounded off in accordance with the rounding-off method of Practice E29.1.3 The values stated in SI units are to be regarded as standard. No other units of measurement are included in this standard. Weight% should be used rather than Mass%.1.4 This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety, health, and environmental practices and determine the applicability of regulatory limitations prior to use. For specific hazard statements see Sections 7 and 9.1.5 This international standard was developed in accordance with internationally recognized principles on standardization established in the Decision on Principles for the Development of International Standards, Guides and Recommendations issued by the World Trade Organization Technical Barriers to Trade (TBT) Committee.

5.1 The flame height and color (indicative of air-to-gas ratio) for a test flame have traditionally been specified in the individual test method. The energy content of the flame has also been addressed by reference to a specific supply gas. It has been determined that the supply-gas back pressure and flow rate can be varied without affecting the height and color of the flame. However, the energy content of the flame is affected. This practice provides the back pressure and flow rate of the supply gas for a 20-mm (50-W) and a 125-mm (500-W) test flame, and a procedure for confirming the heat-evolution profile of the test flame.5.2 Information is provided for test flames using methane, propane, or butane. Using this information, these supply gases have the capability to be used interchangeably with a standardized burner to produce essentially the same test flame.1.1 This practice covers the confirmation of test flames for small-scale burning tests on plastic materials using the laboratory burner described in Specification D5025. Back pressures and flow rates for methane, propane, and butane supply gases are given for specific test flames. This practice describes a procedure to confirm the heat evolution of the test flame.1.2 The values stated in SI units are to be regarded as the standard.1.3 This standard is used to measure and describe the response of materials, products, or assemblies to heat and flame under controlled conditions, but does not by itself incorporate all factors required for fire hazard or fire risk assessment of the materials, products, or assemblies under actual fire conditions.NOTE 1: There is no similar ISO standard. This practice is equivalent in technical content to, but not fully corresponding in presentation with, the confirmatory procedures of IEC/TS 60695-11-3, Method A and IEC/TS 60695-11-4, Method A.1.4 Fire testing is inherently hazardous. Adequate safeguards for personnel and property shall be employed in conducting these tests.1.5 This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety, health, and environmental practices and determine the applicability of regulatory limitations prior to use.1.6 This international standard was developed in accordance with internationally recognized principles on standardization established in the Decision on Principles for the Development of International Standards, Guides and Recommendations issued by the World Trade Organization Technical Barriers to Trade (TBT) Committee.

4.1 Upper limits for the formaldehyde emission rates have been established for wood panel building products made with urea-formaldehyde adhesives and permanently installed in homes or used as components in kitchen cabinets and similar industrial products. This test method is intended for use in conjunction with the test method referenced by HUD 24 for manufactured housing and by Minnesota Statutes for housing units and building materials. This method may also be used for monitoring products for compliance to the California Air Resources Board (CARB) regulation for composite wood products and the Environmental Protection Agency Formaldehyde Emission Standards for Composite Wood Products, EPA TSCA Title VI 40 CFR Section 770. This test method provides a means of testing smaller samples and reduces the time required for testing.4.2 Formaldehyde concentration levels obtained by this small-scale method may differ from expected in full-scale indoor environments. Variations in product loading, temperature, relative humidity, and air exchange will affect formaldehyde emission rates and thus likely indoor air formaldehyde concentrations.4.3 This test method requires the use of a chamber of 0.02 to 1 m3 in volume to evaluate the formaldehyde concentration in air using the following controlled conditions:4.3.1 Conditioning of specimens prior to testing,4.3.2 Exposed surface area of the specimens in the test chamber,4.3.3 Test chamber temperature and relative humidity,4.3.4 The Q/A ratio, and4.3.5 Air circulation within the chamber.1.1 This test method measures the formaldehyde concentrations in air emitted by wood product test specimens under defined test conditions of temperature and relative humidity. Results obtained from this small-scale chamber test method are intended to be comparable to results obtained from testing larger product samples by the large chamber test method for wood products, Test Method E1333. The results may be correlated to values obtained from Test Method E1333. The quantity of formaldehyde in an air sample from the small chamber is determined by a modification of NIOSH 3500 chromotropic acid test procedure. As with Test Method E1333, other analytical procedures may be used to determine the quantity of formaldehyde in the air sample provided that such methods give results comparable to those obtained by using the chromotropic acid procedure. However, the test results and test report must be properly qualified and the analytical procedure employed must be accurately described.1.2 The wood-based panel products to be tested by this test method are characteristically used for different applications and are tested at different relative amounts or loading ratios to reflect different applications. This is a test method that specifies testing at various loading ratios for different product types. However, the test results and test report must be properly qualified and must specify the make-up air flow, sample surface area, and chamber volume.1.3 Ideal candidates for small-scale chamber testing are products relatively homogeneous in their formaldehyde release characteristics. Still, product inhomogeneities must be considered when selecting and preparing samples for small-scale chamber testing.1.4 The values stated in SI units are to be regarded as standard. The values given in parentheses after SI units are provided for information only and are not considered standard.1.5 This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety, health, and environmental practices and determine the applicability of regulatory limitations prior to use.1.6 This international standard was developed in accordance with internationally recognized principles on standardization established in the Decision on Principles for the Development of International Standards, Guides and Recommendations issued by the World Trade Organization Technical Barriers to Trade (TBT) Committee.

6.1 SPF insulation is applied and formed onsite, which creates unique challenges for measuring product emissions. This test method provides a way to measure post-application chemical emissions from SPF insulation.6.2 This test method can be used to identify compounds that emit from SPF insulation products, and the emission factors may be used to compare emissions at the specified sampling times and test conditions.6.3 Emission data may be used in product development, manufacturing quality control and comparison of field samples.6.4 This test method is used to determine chemical emissions from freshly applied SPF insulation samples. The utility of this test method for investigation of odors in building scale environments has not been demonstrated at this time.1.1 This test method is used to identify and to measure the emissions of volatile organic compounds (VOCs) emitted from samples of cured spray polyurethane foam (SPF) insulation using micro-scale environmental test chambers combined with specific air sampling and analytical methods for VOCs.1.2 Specimens prepared from product samples are maintained at specified conditions of temperature, humidity, airflow rate, and elapsed time in micro-scale chambers that are described in Practice D7706. Air samples are collected periodically at the chamber exhaust at the flow rate of the micro-scale chambers.1.2.1 Samples for formaldehyde and other low-molecular weight carbonyl compounds are collected on treated silica gel cartridges and are analyzed by high performance liquid chromatography (HPLC) as described in Test Method D5197 and ISO 16000-3.1.2.2 Samples for other VOCs are collected on multi-sorbent samplers and are analyzed by thermal-desorption gas chromatography / mass spectrometry (TD-GC/MS) as described in U.S. EPA Compendium Method TO-17 and ISO 16000-6.1.3 This test method is intended specifically for SPF insulation products. Compatible product types include two component, high pressure and two-component, low pressure formulations of open-cell and closed-cell SPF insulation.1.4 VOCs that can be sampled and analyzed by this test method generally include organic blowing agents such as 1,1,1,3,3-pentafluoropropane, formaldehyde and other carbonyl compounds, residual solvents, and some amine catalysts. Emissions of some organic flame retardants can be measured after 24 h with this method, such as tris (chloroisopropyl) phosphate (TCPP).1.5 This test method does not cover the sampling and analysis of methylene diphenyl diisocyanate (MDI) or other isocyanates.1.6 Area-specific and mass-specific emission rates are quantified at the elapsed times and chamber conditions as specified in 13.2 and 13.3 of this test method.1.7 This test method is used to identify emitted compounds and to estimate their emission factors at specific times. The emission factors are based on specified conditions, therefore, use of the data to predict emissions in other environments may not be appropriate and is beyond the scope of this test method. The results may not be representative of other test conditions or comparable with other test methods.1.8 This test method is primarily intended for freshly applied, SPF insulation samples that are sprayed and packaged as described in Practice D7859. The measurement of emissions during spray application and within the first hour following application is outside of the scope of this test method.1.9 This test method can also be used to measure the emissions from SPF insulation samples that are collected from building sites where the insulation has already been applied. Potential uses of such measurements include investigations of odor complaints after product application. However, the specific details of odor investigations and other indoor air quality (IAQ) investigations are outside of the scope of this test method.1.10 The values stated in SI units are to be regarded as standard. No other units of measurement are included in this standard.1.11 This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety, health, and environmental practices and determine the applicability of regulatory limitations prior to use.1.12 This international standard was developed in accordance with internationally recognized principles on standardization established in the Decision on Principles for the Development of International Standards, Guides and Recommendations issued by the World Trade Organization Technical Barriers to Trade (TBT) Committee.

This method can be used to assess the anaerobic biodegradability of polymeric components of MSW such as packaging materials and to compare their biodegradability to that of materials routinely buried in landfills such as office paper and newsprint. The procedure can be completed in 6 to 9 months. This timeframe makes it possible to consider waste management during product design. The data from this method makes it possible to characterize the behavior of consumer products at the end of their useful life when they enter the solid waste management system.Limitations—Because decomposition in this test is accelerated, the results reflect the ultimate biodegradability of a material in a landfill. The actual rate of degradability in a full-scale landfill will be affected by landfill environmental conditions as well as the physical characteristics of the material when actually buried.1.1 This test method is designed to measure the anaerobic biodegradability of a material under conditions that simulate accelerated decomposition in a municipal solid waste (MSW) landfill. The test method requires the use of a 14C-labeled material so that biodegradability can be determined by monitoring for methane (14CH4) and gaseous and aqueous carbon dioxide (14CO2(g) and 14CO2(aq)), which are the terminal endproducts of methanogenic decomposition. Methanogenic conditions typically control decomposition in landfills.Note 1—A more complete description of this decomposition is found in Reference (3).1.2 This method could be applied to landfills that contain materials other than MSW. 14C-Radiolabeled material will be added to compost such that between 25 ci and 75 μci activity per 2 litres of test refuse results.Note 2—Adding more radiolabel is desirable because, if the material biodegrades, there will be little residual radiolabel left at the end of the decomposition experiment, which is when the refuse is removed from a reactor and analyzed for residual radiolabel to perform a mass balance. In addition, if insufficient radiolabel is added, then CH4 and CO2(g) production from the added refuse will dilute the 14CH4 and 14CO2(g) from decomposition of the test material, and the labeled gases may not be detected in the reactor offgas.1.3 This measure of anaerobic biodegradability in the laboratory represents what will ultimately occur in a landfill over a long period. The test conditions specified here are designed to accelerate refuse decomposition such that the entire decomposition cycle can be completed in six months.Note 3—This cycle may require decades in a landfill depending upon the actual environmental conditions (moisture content, pH, temperature).1.4 The measured biodegradability obtained here is compared to the biodegradability of both pure and lignified cellulose, which are chemically similar to office paper and newsprint, both of which are routinely buried in landfills.Note 4—The degradability of the referenced compounds is described in References (2) and (5).At this time, there is no standard concerning the extent to which a compound must biodegrade under the test conditions described here to be considered biodegradable. Thus, this test is most appropriately used to measure biodegradability relative to pure and lignified cellulose.1.5 The safety problems associated with refuse and radioactivity are not addressed in this standard. It is the responsibility of the user of this standard to establish appropriate safety and health practices. It is also incumbent on the user to conform to all the regulatory requirements, specifically those that relate to the use of open radioactive sources.Note 5—There are no corresponding ISO standards.

5.1 The test protocol evaluates those complex suspended ceiling systems that cannot be assessed by simple engineering calculations contained in ASCE/SEI 7 and Practice E580/E580M. It is not intended to replace the requirements in ASCE/SEI 7. Suspended ceiling systems are considered nonstructural components of buildings.1.1 These test methods help evaluate the performance of a full-scale suspended ceiling system during a seismic event using a dynamic seismic simulator (shake table).1.2 These full-scale procedures are not the only available procedures for evaluating the seismic performance of ceiling systems. These tests do not preclude the use of other small-scale or full-scale component or system testing.1.3 These test methods contain two independent procedures.1.3.1 Comparative method where the level of performance of an experimental system is compared to that of a control test system under the same set of conditions.1.3.2 Non-comparative method where a single test is conducted to establish the level of performance of an experimental system.1.4 These test procedures are valid and useful for all types of suspended ceiling systems.1.5 The text of this standard uses notes and footnotes that provide explanatory material. These notes and footnotes (excluding those in tables and figures) shall not be considered as requirements of the standard.1.6 The values stated in either SI units or inch-pound units are to be regarded separately as standard. Within the text, the SI units are shown in brackets. The values stated in each system are not necessarily exact equivalents; therefore, to ensure conformance with the standard, each system shall be used independently of the other, and values from the two systems shall not be combined.1.7 This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety, health, and environmental practices and determine the applicability of regulatory limitations prior to use.1.8 This international standard was developed in accordance with internationally recognized principles on standardization established in the Decision on Principles for the Development of International Standards, Guides and Recommendations issued by the World Trade Organization Technical Barriers to Trade (TBT) Committee.

5.1 The demand for SPF insulation in homes and commercial buildings has increased as emphasis on energy efficiency increases. In an effort to protect the health and safety of both trade workers and building occupants due to the application of SPF, it is essential that reentry/reoccupancy-times into the structure where SPF has been applied, be established.5.2 Concentrations of chemical emissions determined in large-scale ventilated enclosure studies conducted by this practice may be used to generate source emission terms for IAQ models.5.3 The emission factors determined using this practice may be used to evaluate comparability and scalability of emission factors determined in other environments.5.4 This practice was designed to determine emission factors for chemicals emitted by SPF insulation in a controlled room environment.5.5 New or existing formulations may be sprayed, and emissions may be evaluated by this practice. The user of this practice is responsible for ensuring analytical methods are appropriate for novel compounds present in new formulations (see Appendix X1 for target compounds and generic formulations).5.6 This practice may be useful for testing variations in emissions from non-ideal applications. Examples of non-ideal applications include those that are off-ratio, applied outside of recommended range of temperature and relative humidity, or applied outside of manufacturer recommendations for thickness.5.7 The determined emission factors are not directly applicable to all potential real-world applications of SPF. While this data can be used for VOCs to estimate indoor environmental concentrations beyond three days, the uncertainty in the predicted concentrations increases with increasing time. Estimating longer term chemical concentrations (beyond three days) for SVOCs is not recommended unless additional data (beyond this practice) is used, see (1).45.8 During the application of SPF, chemicals deposited on the non-applied surfaces (for example, floors and ceilings) are the result of both gaseous phase emissions from the SPF and overspray. It is difficult to separate these two processes with current analytical methods. At present, the difference in how these two processes impact the long-term emissions is not known. This practice combines these two processes to generate data for modeling inputs.1.1 This practice describes procedures for measuring the chemical emissions of volatile and semi-volatile organic compounds (VOCs and SVOCs) from spray polyurethane foam (SPF) insulation samples in a large-scale ventilated enclosure.1.2 This practice is used to identify emission rates and factors during SPF application and up to three days following application.1.3 This practice can be used to generate emissions data for research activities or modeled for the purpose to inform potential reentry and reoccupancy times. Potential reentry and re-occupancy times only apply to the applications that meet manufacturer guidelines and are specific to the tested formulation.1.4 This practice describes emission testing at ambient room and substrate temperature and relative humidity conditions recognizing chemical emissions may differ at different room and substrate temperatures and relative humidity.1.5 This practice does not address all SPF chemical emissions. This practice addresses specific chemical compounds of potential health and regulatory concern including methylene diphenyl diisocyanate (MDI), polymeric MDI (MDI oligomeric polyisocyanates mixture), flame retardants, aldehydes, and VOCs including blowing agents, and catalysts. Although specific chemicals are discussed in this practice, other chemical compounds of interest can be quantified (see target compound and generic formulation list in Appendix X1). Other chemical compounds used in SPF such as polyols, emulsifiers, and surfactants are not addressed by this practice. Particulate sizing and distribution are also outside the scope of this practice.1.6 Emission rates during application are determined from air phase concentration measurements that may include particle bound chemicals. SVOC deposition to floors and ceilings is also quantified for post application modeling inputs. SVOC emission rates should only be used for modeling purposes for the duration of data collection.1.7 Four quantification methods are described for isocyanates. The method chosen should consider safety issues such as flammability, the expected concentration, the presence of isocyanate aerosol during the phase of interest (during and post application), and if the tested SPF is high or low pressure.1.8 This practice references similar standard practices for design, construction, performance evaluation, and use of full-scale chambers for chemical emission testing.1.9 This practice references methods for the collection and analysis of air samples.1.10 This practice applies to two-component open cell and closed cell SPF insulation system formulations that are processed using high-pressure or low-pressure installation processing practices and equipment.1.11 The values stated in SI units are to be regarded as standard. No other units of measurement are included in this standard.1.12 This standard does not purport to address all of the safety concerns, if any, associated with its use. The application of SPF in a ventilated enclosure has the potential to generate a hazardous condition putting the individual responsible for spraying inserts at risk. It is the responsibility of the user of this standard to establish appropriate health and safety procedures and require appropriate certified personal protective equipment (PPE) to minimize chemical exposure. Individuals entering the ventilated enclosure during and after SPF application, for any amount of time, are expected to wear appropriate PPE.1.13 This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety, health, and environmental practices and determine the applicability of regulatory limitations prior to use.1.14 This international standard was developed in accordance with internationally recognized principles on standardization established in the Decision on Principles for the Development of International Standards, Guides and Recommendations issued by the World Trade Organization Technical Barriers to Trade (TBT) Committee.
