4.1 This practice is applicable to all interior and exterior installed building products in the use phase of the product, specifically in the form present in the occupied building. This practice does not cover products during installation processes since those exposures are covered by occupational regulations.4.2 This practice specifies the required information to include in the OESR screening report for product decision makers to assess the potential for occupant health exposure from installed building products in an occupied building operated under normal and anticipated conditions of use.4.3 Fundamental to the selection and use of building products is the consideration of the likelihood of occupant exposure and possible risk to substances in those installed building products.4.4 This practice does not purport to offer full risk information, nor does it purport to be equivalent to an exposure or risk assessment. Rather, it provides screening to inform the product decision maker about conditions that could generate additional discussions with manufacturers or others.4.5 The informational requirements for an OESR are identified in Section 5.4.6 For substances with hazard classifications in 5.3, the OESR informs product decision makers about substances in an installed building product that might trigger a hazard warning to a user or building occupant. This information is designed to help the product decision maker determine whether added information is needed to evaluate exposure and risk more fully in the context of the installed building product’s specific use or application.4.7 The OESR screening report is required to be updated based on the requirements in 9.3.4.8 The OESR is completed by last manufacturer of the building product; this is the manufacturer offering the external or internal building product to the market. This manufacturer may need to obtain information from other manufacturers in its supply chain.NOTE 1: The manufacturer offering the building product to the market is aware of the form, function, and likely uses of the building product under normal conditions of use. If the product contains hazardous substance(s), it is likely that the manufacturer has information about the hazards from the product under foreseeable emergencies in compliance with OSHA requirements.1.1 This practice provides the information required for publishing a screening report for occupant exposure from substances in installed building products (OESR) to communicate possible human health impacts in an occupied building to product specifiers, building owners, and others.1.2 This practice is applicable to all interior and exterior building products in the form used and incorporated into an occupied building.1.3 An article going into the construction market that has potential hazards based upon an evaluation of the United Nations Globally Harmonized System of Classification and Labelling of Chemicals (GHS) (1)2 mixtures guidance is included in the scope of this practice.1.4 This practice does not cover product fabrication or installation processes because these are subject to worker safety and health regulations and law.1.5 The final building product manufacturer offering the building product to the market or agent is responsible for providing this information and completing this report.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.

4.1 The purpose of this test is to obtain, by means of a specified laboratory procedure, the values of the equilibrium moisture content at higher RH levels ((≈ 95 to 100%). These values are used either as means to characterize the material or as material characteristics needed as input to appropriate computer models that can simulate wetting or drying potential of individual building materials or material assemblies under specified environmental conditions.1.1 This test method specifies a laboratory procedure for the determination of the water retention curve (or moisture storage capacity) of porous building materials at very high relative humidity (RH) levels (≈ 95 to 100% RH) corresponding to the capillary moisture region of the sorption isotherm. This is achieved by using the pressure plate test apparatus. This technique was originally developed to study soil moisture content and eventually had been adapted to building construction materials.1.2 At higher RH levels (≈ 95 to 100% RH) of the sorption isotherm (see Test Method C1498), use of climatic chamber is not an option. This technique uses overpressure to extract water out of the pore structure of porous materials until equilibrium between the moisture content in the specimens and the corresponding overpressure is achieved. Using the pressure plate extractors, equilibrium can only be reached by desorption.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 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.

4.1 Standard practices for measuring the economic performance of investments in buildings and building systems have been published by ASTM. A computer program that produces economic measures consistent with these practices is available.4 Discount Factor Tables has been published by ASTM to facilitate computing measures of performance for most of the practices.4.2 This guide can be used to: (1) identify types of building design and system decisions that require economic analysis; (2) match the technically appropriate economic methods with the decisions; and (3) locate the methods in the ASTM practices and adjuncts listed in Section 2.4.3 More than one method can be technically appropriate for many building decisions. Therefore the choice in practice of which technically appropriate economic method to use for evaluating a particular building decision will often depend on the perspective of the user. Some examples of factors that influence the user are: (1) ease of applying the methods, (2) level of familiarity of the user with the methods, (3) preference of the user for different methods, and (4) presence of budget limitations for the projects.4.4 This guide identifies some features and limitations of the methods that might influence users' choices under varying conditions.1.1 This guide identifies types of building design and building system decisions that require economic analysis and recommends ASTM practices, adjuncts, and computer programs that may be used to implement the appropriate economic methods for each decision type.1.2 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 Air infiltration into the conditioned space of a building accounts for a significant portion of the thermal space condition load. Air infiltration can affect occupant comfort by producing drafts, cause indoor air quality problems by carrying outdoor pollutants into occupied building space and, in hot humid climates, can deposit moisture in the building envelope resulting in deterioration of building envelope components. In cold climates, exfiltration of conditioned air out of a building can deposit moisture in the building envelope causing deterioration of building envelope components. Differential pressure across the building envelope and the presence of air leakage sites cause air infiltration and exfiltration (1).45.2 Where restricting air movement between interior zones of a building is desired to separate dissimilar interior environments or prevent the movement of pollutants, the detection practices presented are useful in detecting air leaks between interior zones of the building.5.3 Where practices require controlled flow direction, forced pressurization or depressurization shall be used.NOTE 2: Forced air leakage is required because air leakage sites are often difficult to locate because air flows may be small under the prevailing weather conditions. Wind conditions can aid in air leakage detection by forcing air to enter a building; however, where air is exiting, the building envelope construction may make observations difficult.5.4 The techniques for air leakage site detection covered in these practices allow for a wide range of flexibility in the choice of techniques that are best suited for detecting various types of air leakage sites in specific situations.5.5 The infrared scanning technique for air leakage site detection has the advantage of rapid surveying capability. Entire building exterior surfaces or inside wall surfaces are covered with a single scan or a simple scanning action, provided there are no obscuring thermal effects from construction features or incident solar radiation. The details of a specific air leakage site are then probed more closely by focusing on the local area. Local leak detection is well addressed with the smoke tracer, theatrical fog, anemometer, sound detection, the bubble detection, and the tracer gas techniques, however these techniques are time consuming for large surfaces. The pressurized or depressurized test chamber and smoke tracer or a depressurized test chamber and leak detection liquid practices are used in situations where depressurizing or pressurizing the entire envelope is impractical, such as is the case during construction. Both of the practices enable the detection of very small leaks. To perform these practices requires that the air barrier system is accessible.5.6 Complexity of building air leakage sites diminishes the ability for detection. For example, using the sound detection approach, sound is absorbed in the tortuous path through the insulation. Air moving through such building leakage paths loses some of its temperature differential and thus make thermographic detection difficult. The absence of jet-like air flow at an air leakage site makes detection using the anemometer practice difficult.5.7 Stack effect in multistory commercial buildings can cause gravity dampers to stand open. Computer-controlled dampers shall be placed in normal and night modes to aid in determining the conditions existing in the building. Sensitive pressure measurement equipment is used for evaluating pressure levels between floors and the exterior.1.1 These practices cover standardized techniques for locating air leakage sites in building envelopes and air barrier systems.1.2 Individual practices provide advantages for specific applications.1.3 Some of the practices require a knowledge of infrared scanning, building and test chamber pressurization and depressurization, smoke and fog generation techniques, sound generation and detection, and tracer gas concentration measurement techniques.1.4 The practices described are of a qualitative nature in determining the air leakage sites rather than determining quantitative leakage rates.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. 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 6.1.7 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 Use this practice to identify and measure the amount of actual and effective floor area that will be unavailable to occupants for the placement of people’s workplaces, furniture, and equipment or for circulation.4.2 Findings from use of this practice are intended for optional inclusion with reports of floor area measured in accordance with Practice E1836/E1836M or in accordance with ANSI/BOMA Z65.1–1996.NOTE 1: The choice between using Practice E1836/E1836M or ANSI/BOMA Z65.1–1996 as the basis for measurement depends on the objectives of the analysis. Practice E1836/E1836M is oriented to the traditional interests of design professionals and would be particularly suitable for single-tenant buildings whereas some categories of space measured by ANSI/BOMA Z65.1–1996 are oriented to the leasing of multi-tenant buildings by real estate professionals.4.3 this practice is not intended for use for regulatory purposes, nor for fire hazard assessment, nor for fire risk assessment.1.1 This practice specifies how to measure certain characteristics of a building, known as building loss features, inside the exterior gross area of a floor and how to calculate the amount of actual and effective floor area that will be not be available for the placement of people’s workplaces, furniture, equipment, or for circulation, if using standard furnishings and orthogonal furniture systems.1.2 This practice can be used to specify a performance requirement to limit the amount of floor area that may be taken up by building loss features.1.3 This practice can be used to assess how well a design(s) for an office facility meets a performance requirement regarding floor area.1.4 This practice can be used to assess how well a constructed office building has met a performance requirement regarding floor area.1.5 This practice is not intended for and not suitable for use for regulatory purposes, fire hazard assessment, and fire risk assessment.1.6 Users of this practice should recognize that, in some situations, the amount of certain actual and effective floor area losses may be mitigated to some degree at some cost by custom-tailoring spaces and creating specially fitted furnishings and carpentry to get some value from space which would not otherwise be usable.1.7 The values stated in either SI units or inch-pound 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.1.8 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.1.9 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.
