Standard Test Method for Determining Chemical Emissions from Spray Polyurethane Foam (SPF) Insulation using Micro-Scale Environmental Test Chambers

Standard Test Method for Determining Chemical Emissions from Spray Polyurethane Foam (SPF) Insulation using Micro-Scale Environmental Test Chambers

SIGNIFICANCE AND USE
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.
SCOPE
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.

Standard Guide for Using Probability Sampling Methods in Studies of Indoor Air Quality in Buildings

SIGNIFICANCE AND USE
5.1 Studies of indoor air problems are often iterative in nature. A thorough engineering evaluation of a building (1-4)3 is sometimes sufficient to identify likely causes of indoor air problems. When these investigations and subsequent remedial measures are not sufficient to solve a problem, more intensive investigations may be necessary.  
5.2 This guide provides the basis for determining when probability sampling methods are needed to achieve statistically defensible inferences regarding the goals of a study of indoor air quality. The need for probability sampling methods in a study of indoor air quality depends on the specific objectives of the study. Such methods may be needed to select a sample of people to be asked questions, examined medically, or monitored for personal exposures. They may also be needed to select a sample of locations in space and time to be monitored for environmental contaminants.  
5.3 This guide identifies several potential obstacles to proper implementation of probability sampling methods in studies of indoor air quality in buildings and presents procedures that overcome those obstacles or at least minimize their impact.  
5.4 Although this guide specifically addresses sampling people or locations across time within a building, it also provides important guidance for studying populations of buildings. The guidance in this document is fully applicable to sampling locations to determine environmental quality or sampling people to determine environmental effects within each building in the sample selected from a larger population of buildings.
SCOPE
1.1 This guide covers criteria for determining when probability sampling methods should be used to select locations for placement of environmental monitoring equipment in a building or to select a sample of building occupants for questionnaire administration for a study of indoor air quality. Some of the basic probability sampling methods that are applicable for these types of studies are introduced.  
1.2 Probability sampling refers to statistical sampling methods that select units for observation with known probabilities (including probabilities equal to one for a census) so that statistically defensible inferences are supported from the sample to the entire population of units that had a positive probability of being selected into the sample.  
1.3 This guide describes those situations in which probability sampling methods are needed for a scientific study of the indoor air quality in a building. For those situations for which probability sampling methods are recommended, guidance is provided on how to implement probability sampling methods, including obstacles that may arise. Examples of their application are provided for selected situations. Because some indoor air quality investigations may require application of complex, multistage, survey sampling procedures and because this standard is a guide rather than a practice, the references in Appendix X1 are recommended for guidance on appropriate probability sampling methods, rather than including expositions of such methods in this guide.  
1.4 This standard does not address non-probability sampling approaches. Non-probability sampling approaches may be needed, such as worst-case sampling, range finding sampling, and screening sampling as inputs to help guide and inform probability sampling methods.  
1.5 Units—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 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.

Standard Test Method for Airborne Asbestos Concentration in Ambient and Indoor Atmospheres as Determined by Transmission Electron Microscopy Direct Transfer (TEM)

SIGNIFICANCE AND USE
5.1 This test method is applicable to the measurement of airborne asbestos in a wide range of ambient air situations and for detailed evaluation of any atmosphere for asbestos structures. Most fibers in ambient atmospheres are not asbestos, and therefore, there is a requirement for fibers to be identified. Most of the airborne asbestos fibers in ambient atmospheres have diameters below the resolution limit of the light microscope. This test method is based on transmission electron microscopy, which has adequate resolution to allow detection of small thin fibers and is currently the only technique capable of unequivocal identification of the majority of individual fibers of asbestos. Asbestos is often found, not as single fibers, but as very complex, aggregated structures, which may or may not also be aggregated with other particles. The fibers found suspended in an ambient atmosphere can often be identified unequivocally if sufficient measurement effort is expended. However, if each fiber were to be identified in this way, the analysis would become prohibitively expensive. Because of instrumental deficiencies or because of the nature of the particulate matter, some fibers cannot be positively identified as asbestos even though the measurements all indicate that they could be asbestos. Therefore, subjective factors contribute to this measurement, and consequently, a very precise definition of the procedure for identification and enumeration of asbestos fibers is required. The method defined in this test method is designed to provide a description of the nature, numerical concentration, and sizes of asbestos-containing particles found in an air sample. The test method is necessarily complex because the structures observed are frequently very complex. The method of data recording specified in the test method is designed to allow reevaluation of the structure-counting data as new applications for measurements are developed. All of the feasible specimen preparation techn...
SCOPE
1.1 This test method2 is an analytical procedure using transmission electron microscopy (TEM) for the determination of the concentration of asbestos structures in ambient atmospheres and includes measurement of the dimension of structures and of the asbestos fibers found in the structures from which aspect ratios are calculated.  
1.1.1 This test method allows determination of the type(s) of asbestos fibers present.  
1.1.2 This test method cannot always discriminate between individual fibers of the asbestos and non-asbestos analogues of the same amphibole mineral.  
1.2 This test method is suitable for determination of asbestos in both ambient (outdoor) and building atmospheres.  
1.2.1 This test method is defined for polycarbonate capillary-pore filters or cellulose ester (either mixed esters of cellulose or cellulose nitrate) filters through which a known volume of air has been drawn and for blank filters.  
1.3 The upper range of concentrations that can be determined by this test method is 7000 s/mm2. The air concentration represented by this value is a function of the volume of air sampled.  
1.3.1 There is no lower limit to the dimensions of asbestos fibers that can be detected. In practice, microscopists vary in their ability to detect very small asbestos fibers. Therefore, a minimum length of 0.5 μm has been defined as the shortest fiber to be incorporated in the reported results.  
1.4 The direct analytical method cannot be used if the general particulate matter loading of the sample collection filter as analyzed exceeds approximately 10 % coverage of the collection filter by particulate matter.  
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 appropri...

Standard Practice for Rapid Screening of VOC Emissions from Products Using Micro-Scale Chambers

SIGNIFICANCE AND USE
6.1 Manufacturers increasingly are being asked or required to demonstrate that vapor-phase emissions of chemicals of concern from their products under normal use conditions comply with various voluntary or regulatory acceptance criteria. This process typically requires manufacturers to have their products periodically tested for VOC emissions by independent laboratories using designated reference test methods (for example, Test Method D6007, ISO 16000-9, and ISO 16000-10). To ensure continuing compliance, manufacturers may opt to, or be required to, implement screening tests at the production level.  
6.2 Reference methods for testing chemical emissions from products are rigorous and typically are too time-consuming and impractical for routine emission screening in a production environment.  
6.3 Micro-scale chambers are unique in that their small size and operation at moderately elevated temperatures facilitate rapid equilibration and shortened testing times. Provided a sufficiently repeatable correlation with reference test results can be demonstrated, appropriate control levels can be established and micro-scale chamber data can be used to monitor product manufacturing for likely compliance with reference acceptance criteria. Enhanced turnaround time for results allows for more timely adjustment of parameters to maintain consistent production with respect to vapor-phase chemical emissions.  
6.4 This practice can also be used to monitor the quality of raw materials for manufacturing processes.  
6.5 The use of elevated temperatures additionally facilitates screening tests for emissions of semi-volatile VOCs (SVOCs) such as some phthalate esters and other plasticizers.
SCOPE
1.1 This practice describes a micro-scale chamber apparatus and associated procedures for rapidly screening materials and products for their vapor-phase emissions of volatile organic compounds (VOCs) including formaldehyde and other carbonyl compounds. It is intended to complement, not replace reference methods for measuring chemical emissions for example, small-scale chamber tests (Guide D5116) and emission cell tests (Practice D7143).  
1.2 This practice is suitable for use in and outside of laboratories, in manufacturing sites and in field locations with access to electrical power.  
1.3 Compatible material/product types that may be tested in the micro-scale chamber apparatus include rigid materials, dried or cured paints and coatings, compressible products, and small, irregularly-shaped components such as polymer beads.  
1.4 This practice describes tests to correlate emission results obtained from the micro-scale chamber with results obtained from VOC emission reference methods (for example, Guide D5116, Test Method D6007, Practice D7143, and ISO 16000-9 and ISO 16000-10).  
1.5 The micro-scale chamber apparatus operates at moderately elevated temperatures, 30 °C to 60 °C, to eliminate the need for cooling, to reduce test times, boost emission rates, and enhance analytical signals for routine emission screening, and to facilitate screening of semi-volatile VOC (SVOC) emissions such as emissions of some phthalate esters and other plasticizers.  
1.6 Gas sample collection and chemical analysis are dependent upon the nature of the VOCs targeted and are beyond the scope of this practice. However, the procedures described in Test Method D7339, Practice D6196 and ISO 16000-6 for analysis of VOCs and in Test Method D5197 and ISO 16000-3 for analysis of formaldehyde and other carbonyl compounds are applicable to this practice.  
1.7 The values stated in SI units are to be regarded as standard. No other units of measurement are included in this 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 applicabilit...

Standard Test Method for Determination of Non-methane Organic Compounds (NMOC) in Ambient Air Using Cryogenic Preconcentration and Direct Flame Ionization Detection

SIGNIFICANCE AND USE
5.1 Many regulators, industrial processes, and other stakeholders require determination of NMOC in atmospheres.  
5.2 Accurate measurements of ambient NMOC concentrations are critical in devising air pollution control strategies and in assessing control effectiveness because NMOCs are primary precursors of atmospheric ozone and other oxidants (7, 8).  
5.2.1 The NMOC concentrations typically found at urban sites may range up to 1 ppm C to 3 ppm C or higher. In order to determine transport of precursors into an area monitoring site, measurement of NMOC upwind of the site may be necessary. Rural NMOC concentrations originating from areas free from NMOC sources are likely to be less than a few tenths of 1 ppm C.  
5.3 Conventional test methods based upon gas chromatography and qualitative and quantitative species evaluation are relatively time consuming, sometimes difficult and expensive in staff time and resources, and are not needed when only a measurement of NMOC is desired. The test method described requires only a simple, cryogenic pre-concentration procedure followed by direct detection with an FID. This test method provides a sensitive and accurate measurement of ambient total NMOC concentrations where speciated data are not required. Typical uses of this standard test method are as follows.  
5.4 An application of the test method is the monitoring of the cleanliness of canisters.  
5.5 Another use of the test method is the screening of canister samples prior to analysis.  
5.6 Collection of ambient air samples in pressurized canisters provides the following advantages:  
5.6.1 Convenient collection of integrated ambient samples over a specific time period,  
5.6.2 Capability of remote sampling with subsequent central laboratory analysis,  
5.6.3 Ability to ship and store samples, if necessary,  
5.6.4 Unattended sample collection,  
5.6.5 Analysis of samples from multiple sites with one analytical system,  
5.6.6 Collection of replicate samples for ...
SCOPE
1.1 This test method2 presents a procedure for sampling and determination of non-methane organic compounds (NMOC) in ambient, indoor, or workplace atmospheres.  
1.2 This test method describes the collection of integrated whole air samples in silanized or other passivated stainless steel canisters, and their subsequent laboratory analysis.  
1.2.1 This test method describes a procedure for sampling in canisters at final pressures above atmospheric pressure (pressurized sampling).  
1.3 This test method employs a cryogenic trapping procedure for concentration of the NMOC prior to analysis.  
1.4 This test method describes the determination of the NMOC by the flame ionization detection (FID), without the use of gas chromatographic columns and other procedures necessary for species separation.  
1.5 The range of this test method is from 20 ppb C to 10 000 ppb C (1, 2).3  
1.6 This test method has a larger uncertainty for some halogenated or oxygenated hydrocarbons than for simple hydrocarbons or aromatic compounds. This is especially true if there are high concentrations of chlorocarbons or chlorofluorocarbons present.  
1.7 The values stated in SI units are to be regarded as standard. The values given in parentheses are mathematical conversions to inch-pound units that are provided for information only and are not considered 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 Techn...

ASTM D8141-22(Guide)
Standard Guide for Selecting Volatile Organic Compounds (VOCs) and Semi-Volatile Organic Compounds (SVOCs) Emission Testing Methods to Determine Emission Parameters for Modeling of Indoor Environments

SIGNIFICANCE AND USE
4.1 Emissions of VOCs are typically controlled by internal mass-transfer limitations (for example, diffusion through the material), while emissions of SVOCs are typically controlled by external mass-transfer limitations (migration through the air immediately above the material). The emission of some chemicals may be controlled by both internal and external mass-transfer limitations. In addition, due to their lower vapor pressure, SVOCs generally adsorb to different media (chamber walls, building materials, particles, and other surfaces) at greater rates than VOCs. This sorption can increase the amount of time required to reach steady-state SVOC concentrations using conventional VOC emission test methods to months for a single test (2).  
4.2 Thus, existing methods for characterizing emissions of VOCs may not be appropriate or practical to properly characterize emission rates of SVOCs for use in modeling SVOC concentrations in indoor environments. A mass-transfer framework is needed to accurately assess emission rates of SVOCs when predicting the SVOC indoor air concentrations in indoor environments. The SVOC mass-transfer framework includes SVOC emission characteristics and its partition to multimedia including sorption to indoor surfaces, airborne particles, and settled dust. Once the SVOC emission parameters and partitioning coefficients have been determined, these values can be used to modeling SVOC indoor concentrations.
SCOPE
1.1 This guide is intended to serve as a foundation for understanding when to use emission testing methods designed for volatile organic compounds (VOCs) to determine area-specific emission rates that are typically used in modeling indoor air VOC concentrations and when to use emission testing methods designed for semi-volatile organic compounds (SVOCs) to determine mass transfer emission parameters that are typically used to model indoor air, dust, and surface SVOC concentrations.  
1.2 This guide discusses how organic chemicals are conventionally categorized with respect to volatility.  
1.3 This guide presents a simplified mass-transfer model describing organic chemical emissions from a material to bulk air. The values of the model parameters are shown to be specific to material/chemical/chamber combinations.  
1.4 This guide shows how to use a mass-transfer model to estimate whether diffusion of the chemical within the material or convective mass transfer of the chemical from the surface of the material to the overlying air limits chemical emissions from the material surface.  
1.5 This guide describes the range of different chambers that are available for emission testing. The chambers are classified as either dynamic or static and either conventional or sandwich. The chambers are categorized as being optimal to determine either the area-specific emission rate or mass-transfer emission parameters.  
1.6 This guide discusses the roles sorption and convective mass-transfer coefficients play in selecting the appropriate emission chamber and analysis method to accurately and efficiently characterize emissions from indoor materials for use in modeling indoor chemical concentrations.  
1.7 This guide recommends when to choose an emission test method that is optimized to determine either the area-specific emission rate or mass-transfer emission parameters. For chemicals where the controlling mass-transfer process is unknown, the guide outlines a procedure to determine if the chemical emission is controlled by convective mass transfer of the chemical from the material.  
1.8 This guide does not provide specific guidance for measuring emission parameters or conducting indoor exposure modeling.  
1.9 Mechanisms controlling emissions from wet and dry materials and products are different. This guide considers the emission of chemicals from dry materials and products. Examples of functional uses of VOCs and SVOCs that this guide applies to include blowing agents, ...

Standard Practice for Measuring Chemical Emissions from Spray Polyurethane Foam (SPF) Insulation Samples in a Large-scale Ventilated Enclosure

SIGNIFICANCE AND USE
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).4  
5.8 During the application of SPF, chemicals deposited on the non-applie...
SCOPE
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 durati...

Standard Practice for Calibration of Ozone Monitors and Certification of Ozone Transfer Standards Using Ultraviolet Photometry

SIGNIFICANCE AND USE
5.1 The reactivity and instability of O3 preclude the storage of O3 concentration standards for any practical length of time, and precludes direct certification of O3 concentrations as Standard Reference Materials (SRMs). Moreover, there is no available SRM that can be readily and directly adapted to the generation of O3 standards analogous to permeation devices and standard gas cylinders for sulfur dioxide and nitrogen oxides. Dynamic generation of O3 concentrations is relatively easy with a source of ultraviolet (UV) radiation. However, accurately certifying an O3 concentration as a primary standard requires assay of the concentration by a comprehensively specified analytical procedure, which must be performed every time a standard is needed (10).  
5.2 This practice is not designed for the routine calibration of O3 monitors at remote locations (see Practices D5011).
SCOPE
1.1 This practice covers a means for calibrating ambient, workplace, or indoor ozone monitors, and for certifying transfer standards to be used for that purpose.  
1.2 This practice describes means by which dynamic streams of ozone in air can be designated as primary ozone standards.  
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. See Section 8 for specific precautionary statements.  
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.

Standard Test Method for Determination of Radon Decay Product Concentration and Working Level in Indoor Atmospheres by Active Sampling on a Filter

SIGNIFICANCE AND USE
5.1 The test method provides a relatively simple method for determination of the concentration of RDP without the need for specialty equipment built expressly for such purposes.  
5.2 Using this test method will afford investigators of radon in dwellings a technique by which the RDP can be determined. The use of the results of this test method are generally for diagnostic purposes and are not necessarily indicative of results that might be obtained by longer term measurement methods.  
5.3 An improved understanding of the frequency of elevated radon in buildings and the health effect of exposure has increased the importance of knowledge of actual exposures. The measurement of RDP, which are the direct cause of potential adverse health effects, should be conducted in a manner that is uniform and reproducible; it is to this end that this test method is addressed.
SCOPE
1.1 This test method provides instruction for using the grab sampling filter technique to determine accurate and reproducible measurements of indoor radon decay product (RDP) concentrations and of the working level (WL) value corresponding to those concentrations.  
1.2 Measurements made in accordance with this test method will produce RDP concentrations representative of closed-building conditions. Results of measurements made under closed-building conditions will have a smaller variability and are more reproducible than measurements obtained when building conditions are not controlled. This test method may be utilized under non-controlled conditions, but a greater degree of variability in the results will occur. Variability in the results may also be an indication of temporal variability present at the sampling site.  
1.3 This test method utilizes a short sampling period and the results are indicative of the conditions only at the place and time of sampling. The results obtained by this test method are not necessarily indicative of longer terms of sampling and should not be confused with such results. The averaging of multiple measurements over hours and days can, however, provide useful screening information. Individual measurements are generally obtained for diagnostic purposes.  
1.4 The range of the test method may be considered from 0.0005 WL to unlimited working levels, and from 40 Bq/m3 to unlimited for each individual radon decay product.  
1.5 This test method provides information on equipment, procedures, and quality control. It provides for measurements within typical residential or building environments and may not necessarily apply to specialized circumstances, for example, clean rooms.  
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. See Section 9 for additional precautions  
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.
