5.1 O2GTR at a given temperature and %RH is an important determinant of the packaging protection afforded by barrier materials. It is not, however the sole determinant, and additional tests, based on experience, must be used to correlate packaging performance with O2GTR. It is suitable as a referee method of testing, provided that purchaser and seller have agreed on sampling procedures, standardization procedures, test conditions and acceptance criteria.1.1 This test method covers a procedure for determination of the rate of transmission of oxygen gas, at steady-state, at a given temperature and %RH level, through film, sheeting, laminates, co-extrusions, or plastic-coated papers or fabrics. This test method extends the common practice dealing with zero humidity or, at best, an assumed humidity. Humidity plays an important role in the oxygen gas transmission rate (O2GTR) of many materials. This test method provides for the determination of oxygen gas transmission rate (O2GTR), the permeance of the film to oxygen gas (PO2), the permeation coefficient of the film to its thickness (P”O2), and oxygen permeability coefficient (PʹO2) in the case of homogeneous materials at given temperature and %RH level(s).1.2 The values stated in SI units are to be regarded as the standard.1.3 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.

Nitrogen- and phosphorus-containing compounds are widely used in agriculture as pre-emergent agents to increase crop yields. Runoff from farmlands into lakes and streams as well as accidental discharge from irrigation systems into groundwater introduces these compounds into the environment. This discharge from agricultural areas along with possible health implications dictates a need to monitor the presence of these compounds.1.1 This is a gas chromatographic (GC) test method applicable to the determination of certain nitrogen- and phosphorus-containing pesticides in ground water and finished drinking water. The analytes listed in have been validated using this test method.1.2 This test method has been validated on reagent water and finished drinking water by 10 volunteer laboratories. Summary statistics were calculated for mean recovery, overall method precision and bias and single analyst precision using a computer program, Interlaboratory Method Validation Study (IMVS).1.3 Collaborative study showed the test method to be acceptable for all analytes tested except merphos, which decomposed in the GC injection port.1.4 This test method is restricted to use by or under the supervision of analysts experienced in the use of GC and in the interpretation of gas chromatograms. Each analyst must demonstrate the ability to generate acceptable results with this test method using the procedure described in 12.3.1.5 Analytes that are not separated chromatographically, that is, analytes which have very similar retention times, cannot be individually identified and measured in the same calibration mixture or water sample unless an alternative technique for identification and quantitation exist (13.5).1.6 When this test method is used to analyze unfamiliar samples for any or all of the analytes above, analyte identifications should be confirmed by at least one additional qualitative technique.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 and health practices and determine the applicability of regulatory limitations prior to use.

5.1 These test methods are useful for locating and estimating the size of pressurized gas leaks, either as quality control tests or as field inspection procedures. Also, they are valuable as pretests before other more time consuming and more sensitive leak tests are employed. These test methods are semi-quantitative techniques used to locate leaks but cannot be used to quantify except for approximation. These test methods may be used in an accept-reject test mode.1.1 This practice covers procedures for detecting the sources of gas leaking at the rate of 1 × 10 –5 Pa m3/s (1 × 10–4 standard cm3/s) or greater. The tests may be conducted on any object that can be pressurized with a tracer gas that is detectable by a thermal conductivity detector. The test sensitivity will vary widely depending on the tracer gas used.1.2 Units—The values stated in either SI or std-cc/sec units are to be regarded separately as standard. The values stated in each system may not be exact equivalents: therefore, each system shall be used independently of the other. Combining values from the two systems may result in non-conformance with the standard.1.3 This standard does not purport to address all of the safety concerns, if any, associated with its use.

5.1 This test method is of particular use as a quality control tool for a molding or synthesis operation. Acetaldehyde is a volatile degradation product generated during melt processing of PET. Thus, it becomes trapped in the sidewalls of a molded article and desorbs slowly into the contents packaged therein. In some foods and beverages AA can impart an off-taste that is undesirable, thus, it is important to know its concentration in PET articles that are to be used in food contact applications.5.2 The desorption conditions of 150 °C for 60 min are such that no measurable AA is generated by the sample during the desorption process.1.1 This test method covers a gas chromatographic procedure for the determination of the ppm residual acetaldehyde (AA) present in poly(ethylene terephthalate) (PET) homo-polymers and co-polymers which are used in the manufacture of beverage bottles. This includes sample types of both amorphous and solid-stated pellet and preform samples, as opposed to the bottle test, Test Method D4509, an acetaldehyde test requiring 24 h of desorption time at 23 °C into the bottle headspace and then the concentration of the headspace quantified by a similar GC method.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.

6.1 Methods A or B are useful in testing hermetically-sealed devices with internal volumes. Maximum acceptable leak rates have been established for microelectronic devices to assure performance characteristics will not be affected by in-leakage of air, water vapor or other contaminants over the projected life expected. Care must be taken to control the bombing pressure, bombing time and dwell time after bombing or the results can vary substantially.1.1 This practice2 covers procedures for testing devices that are sealed prior to testing, such as semiconductors, hermetically enclosed relays, pyrotechnic devices, etc., for leakage through the walls of the enclosure. They may be used with various degrees of sensitivity (depending on the internal volume, the strength of the enclosure, the time available for preparation of test, and on the sorption characteristics of the enclosure material for helium). In general practice the sensitivity limits are from 10−10 to 10−6 Pa m3/s (10−9 standard cm3/s to 10−5 standard cm3/s at 0°C) for helium, although these limits may be exceeded by several decades in either direction in some circumstances.1.2 Two test methods are described:1.2.1 Test Method A—Test part preparation by bombing.1.2.2 Test Method B—Test part preparation by prefilling.1.3 Units—The values stated in either SI or std-cc/sec units are to be regarded separately as standard. The values stated in each system may not be exact equivalents: therefore, each system shall be used independently of the other. Combining values from the two systems may result in non-conformance with the standard.1.4 This standard does not purport to address all of the safety concerns, if any, associated with its use.

AbstractThese methods cover general procedures for the calibration of radiation detectors and the analysis of radionuclides. For each individual radionuclide, one or more of these methods may apply. These methods are concerned only with specific radionuclide measurements. The chemical and physical properties of the radionuclides are beyond the scope of this standard. Among the measurement standards discussed are: the calibration and usage of germanium detectors, scintillation detector systems, scintillation detectors for simple and complex spectra, and counting methods such as beta particle counting, aluminum absorption curve, alpha particle counting, and liquid scintillation counting. For each of the methods, the scope, apparatus used, summary of methods, preparation of apparatus, calibration procedure, measurement of radionuclide, performance testing, sources of uncertainty, precautions and tests, and calculations are detailed.1.1 This guide covers general procedures for the calibration of radiation detectors and measurement for radiation metrology for reactor dosimetry. For any particular radionuclide, one or more of these methods may apply.1.2 These techniques are concerned only with specific radionuclide measurements. The chemical and physical properties of the radionuclides are not within the scope of this standard.1.3 E3376, Standard Practice for Calibration and Usage of Germanium Detectors in Radiation Metrology for Reactor Dosimetry, was previously in Guide E181 and is now found in Volume 12.02 of the Annual Book of ASTM Standards. The discussion herein is not a sufficient substitute for the full standard. This guide is specifically NOT to be used as a direct reference to Practice E3376. Only the standard listed provides sufficient information to serve as a reference.1.4 Additional information on the setup, calibration, and quality control for radiometric detectors and measurements is given in Guide C1402 and Practice D7282.1.5 The values stated in SI units are to be regarded as standard. No other units of measurement are included in this standard.1.6 This standard does not purport to address all of the safety concerns, if any, associated with its use.

6.1 Test Method A is the most frequently used in leak testing components which are structurally capable of being evacuated to pressures of 0.1 Pa (approximately 10−3 torr). Testing of small components can be correlated to calibrated leaks, and the actual leak rate can be measured or acceptance can be based on a maximum allowable leak. For most production needs acceptance is based on acceptance of parts leaking less than an established standard which will ensure safe performance over the projected life of the component. Care must be exercised to ensure that large systems are calibrated with reference leak at a representative place on the test volume. Leak rates are determined by calculating the net gain or loss through a leak in the test part that would cause failure during the expected life of the device.6.2 Test Method B is used for testing vacuum systems either as a step in the final test of a new system or as a maintenance practice on equipment used for manufacturing, environmental test or for conditioning parts. As the volume tends to be large, a check of the response time as well as system sensitivity should be made. Volume of the system in liters divided by the speed of the vacuum pump in L/s will give the response time to reach 63 % of the total signal. Response times in excess of a few seconds makes leak detection difficult.6.3 Test Method C is to be used only when there is no convenient method of connecting the leak detector to the outlet of the high vacuum pump. If a helium leak detector is used and the high vacuum pump is an ion pump or cryopump, leak testing is best accomplished during the roughing cycle as these pumps leave a relatively high percentage of helium in the high vacuum chamber. This will obscure all but large leaks, and the trace gas will quickly saturate the pumps.1.1 This practice covers procedures for testing and locating the sources of gas leaking at the rate of 1 × 10 −8 Pa m3/s (1 × 10−9 Std cm 3/s)3 or greater. The test may be conducted on any object to be tested that can be evacuated and to the other side of which helium or other tracer gas may be applied.1.2 Three test methods are described:1.2.1 Test Method A—For the object under test capable of being evacuated, but having no inherent pumping capability.1.2.2 Test Method B—For the object under test with integral pumping capability.1.2.3 Test Method C—For the object under test as in Test Method B, in which the vacuum pumps of the object under test replace those normally used in the leak detector.1.3 Units—The values stated in either SI or std-cc/sec units are to be regarded separately as standard. The values stated in each system may not be exact equivalents: therefore, each system shall be used independently of the other. Combining values from the two systems may result in non-conformance with the standard.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.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.

6.1 Test Method A is frequently used to test large systems and complex piping installations that can be filled with a trace gas. Helium is normally used. The test method is used to locate leaks but cannot be used to quantify except for approximation. Care must be taken to provide sufficient ventilation to prevent increasing the helium background at the test site. Results are limited by the helium background and the percentage of the leaking trace gas captured by the probe.6.2 Test Method B is used to increase the concentration of trace gas coming through the leak by capturing it within an enclosure until the signal above the helium background can be detected. By introducing a calibrated leak into the same volume for a recorded time interval, leak rates can be measured.1.1 This practice covers procedures for testing and locating the sources of gas leaking at the rate of 1 × 10 −7 Pa m3/s (1 × 10−8 Std cm3/s)3 or greater. The test may be conducted on any device or component across which a pressure differential of helium or other suitable tracer gas may be created, and on which the effluent side of the leak to be tested is accessible for probing with the mass spectrometer sampling probe.1.2 Two test methods are described:1.2.1 Test Method A—Direct probing, and1.2.2 Test Method B—Accumulation.1.3 Units—The values stated in either SI or std-cc/sec units are to be regarded separately as standard.

5.1 EPA regulations require Portland cement plants that burn hazardous waste to use BLDs or PMDs to provide either a relative or an absolute indication of PM concentration and to alert the plant operator of the need to inspect PM control equipment or initiate corrective action. EPA and others have not established for these applications specific design and performance specifications for these instruments. The design and performance specifications and test procedures contained in this practice will help ensure that measurement systems are capable of providing reliable monitoring data.5.2 This practice identifies relevant information and operational characteristics of BLD and PMD monitoring devices for Portland cement kiln systems. This practice will assist equipment suppliers and users in the evaluation and selection of appropriate monitoring equipment.5.3 This practice requires that tests be conducted to verify manufacturer’s published specifications for detection limit, linearity, thermal stability, insensitivity to supply voltage variations and other factors so that purchasers can rely on the manufacturer’s published specifications. Purchasers are also assured that the specific instrument has been tested at the point of manufacture and shown to meet selected design and performance specifications prior to shipment.5.4 This practice requires that the manufacturer develop and provide to the user written procedures for installation start-up, operation, maintenance, and quality assurance of the equipment. This practice requires that these same procedures are used for a field performance demonstration of the BLD or PMD monitoring equipment at a Portland cement plant.5.5 The applicable test procedures and specifications of this practice are selected to address the equipment and activities that are within the control of the manufacturer.5.6 This practice also may serve as the basis for third party independent audits of the certification procedures used by manufacturers of PMD or BLD equipment.1.1 This practice covers the procedure for certifying particulate matter detectors (PMDs) and bag leak detectors (BLDs) that are used to monitor particulate matter (PM) emissions from kiln systems at Portland cement plants that burn hazardous waste. It includes design specifications, performance specifications, test procedures, and information requirements to ensure that these continuous monitors meet minimum requirements, necessary in part, to monitor reliably PM concentrations to indicate the need for inspection or corrective action of the types of air pollution control devices that are used at Portland cement plants that burn hazardous waste.1.2 This practice applies specifically to the original manufacturer, or to those involved in the repair, remanufacture, or resale of PMDs or BLDs.1.3 This practice applies to (a) wet or dry process cement kilns equipped with electrostatic precipitators, and (b) dry process kilns, including pre-heater pre-calciner kiln systems, equipped with fabric filter controls. Some types of monitoring instruments are suitable for only certain types of applications.NOTE 1: This practice has been developed based on careful consideration of the nature and variability of PM concentrations, effluent conditions, and the type, configuration, and operating characteristics of air pollution control devices used at Portland cement plants that burn hazardous waste.1.4 This practice applies to Portland cement kiln systems subject to PM emission standards contained in 40 CFR 63, Subpart EEE.NOTE 2: The level of the PM emission limit is relevant to the design and selection of appropriate PMD and BLD instrumentation. The current promulgated PM emission standards (70 FR 59402, Oct. 12, 2005) are: (a) 65 mg/dscm at 7 % O2 (0.028 gr/dscf at 7 % O2) or approximately 30 mg/acm (0.013 gr/acf) for “existing sources” and (b) 5.3 mg/dscm at 7 % O2 (0.0023 gr/dscf at 7 % O2) or approximately 2.5 mg/acm (0.001 gr/acf) for “new sources.” On March 23, 2006 (71 FR 14665), EPA proposed to revise the PM standard for new cement plants to 15.9 mg/dscm at 7 % O2 (0.0069 gr/dscf at 7 % O2), or about 6–9 mg/acm (0.0026–0.0039 gr/acf). The emission standards may change in future rulemakings, so users of this practice should check the current regulations. Some types of monitoring instruments are not suitable for use over the range of emissions encountered at both new and existing sources.1.5 The specifications and test procedures contained in this practice exceed those of the United States Environmental Protection Agency (USEPA). For each monitoring device that the manufacturer demonstrates conformance to this practice, the manufacturer may issue a certificate that states that monitoring device conforms with all of the applicable design and performance requirements of this practice and also meets all applicable requirements for PMDs or BLDs at 40 CFR 63, Subpart EEE, which apply to Portland cement plants.NOTE 3: 40 CFR 63.1206 (c)(8) and (9) requires that BLDs and PMDs “be certified by the manufacturer to be capable of detecting particulate matter emissions at concentrations of 1.0 milligrams per actual cubic meter unless you demonstrate under §63.1209(g), that a higher detection limit would routinely detect particulate matter loadings during normal operations.” This practice includes specific procedures for determination and reporting of the detection limit for each PMD or BLD model.1.6 The values stated in SI units are to be regarded as standard. No other units of measurement are included in this standard.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.
