1.1 This practice is intended for determining volatile organic compound (VOC) emissions from materials and products (building materials, material systems, furniture, consumer products, etc.) and equipment (printers, photocopiers, air cleaners, etc.) under environmental and product usage conditions that are typical of those found in office and residential buildings.1.2 This practice is for identifying VOCs emitted and determining their emission rates over a period of time.1.3 This practice describes the design, construction, performance evaluation, and use of full-scale chambers for VOC emission testing.1.4 While this practice is limited to the measurement of VOC emissions, many of the general principles and procedures (such as methods for evaluating the general performance of the chamber system) may also be useful for the determination of other chemical emissions (for example, ozone, nitrogen dioxide). Determination of aerosol and particle emissions is beyond the scope of this document.

1.1 This guide provides techniques that are useful for the comparison of modeled air concentrations with observed field data. Such comparisons provide a means for assessing a model's performance, for example, bias and precision or uncertainty, relative to other candidate models. Methodologies for such comparisons are yet evolving; hence, modifications will occur in the statistical tests and procedures and data analysis as work progresses in this area. Until the interested parties agree upon standard testing protocols, differences in approach will occur. This guide describes a framework, or philosophical context, within which one determines whether a model's performance is significantly different from other candidate models. It is suggested that the first step should be to determine which model's estimates are closest on average to the observations, and the second step would then test whether the differences seen in the performance of the other models are significantly different from the model chosen in the first step. An example procedure is provided in Appendix X1 to illustrate an existing approach for a particular evaluation goal. This example is not intended to inhibit alternative approaches or techniques that will produce equivalent or superior results. As discussed in Section 6, statistical evaluation of model performance is viewed as part of a larger process that collectively is referred to as model evaluation.1.2 This guide has been designed with flexibility to allow expansion to address various characterizations of atmospheric dispersion, which might involve dose or concentration fluctuations, to allow development of application-specific evaluation schemes, and to allow use of various statistical comparison metrics. No assumptions are made regarding the manner in which the models characterize the dispersion.1.3 The focus of this guide is on end results, that is, the accuracy of model predictions and the discernment of whether differences seen between models are significant, rather than operational details such as the ease of model implementation or the time required for model calculations to be performed.1.4 This guide offers an organized collection of information or a series of options and does not recommend a specific course of action. This guide cannot replace education or experience and should be used in conjunction with professional judgment. Not all aspects of this guide may be applicable in all circumstances. This guide is not intended to represent or replace the standard of care by which the adequacy of a given professional service must be judged, nor should it be applied without consideration of a project's many unique aspects. The word "Standard" in the title of this guide means only that the document has been approved through the ASTM consensus process.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 and health practices and to determine the applicability of regulatory limitations prior to use.

These test methods may be used for determining the fluoride content of particulate matter and gases collected from the atmosphere by passive and active means, including plant tissues. The user is warned that the fluoride content of passive collectors (including plants) give only qualitative or semiquantitative measurement of atmospheric fluoride content.1.1 These test methods describe the semiautomated procedure for the analyses of various types of samples for the purpose of determining total fluoride. Since the test methods incorporate microdistillation of the sample, they may be applied to any fluoride-containing solution where standards of identical composition have been carried through the same sample preparation procedures and have proven to provide quantitative recovery when analyzed by the semiautomated system. Conversely, the methods shall not be applied for analyses until the applicability has been demonstrated.1.2 In normal use, the procedure can detect 0.1 g/mL of F. The normal range of analysis is from 0.1 to 1.6 g/mL of F. Higher concentrations can be analyzed by careful dilution of samples with reagent water. If digested samples routinely exceed 1.6 g/mL of F, the analytical portion of the pump manifold can be modified to reduce sensitivity. However, the best procedure is to analyze a smaller aliquot of the sample. Most accurate results are obtained when the fluoride concentration falls in the middle or upper part of the calibration curve.1.3 The values stated in SI units are to be regarded as the standard. The values given in parentheses are for information only.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.

1.1 This guide describes how to conduct, document and report findings of a lead hazard assessment in residential dwellings and other buildings and related areas known to contain, or are suspected to contain, lead hazards. Lead hazard assessments are intended to be conducted by certified risk assessors. This guide is applicable for use in either occupied or unoccupied properties. The use of this guide to produce accurate results is dependent on the training, experience, and knowledge of the risk assessor conducting the lead hazard assessment. Use of the procedures in this guide, when supplemented by the evaluation and recommendation process that determines action plans for controlling assessed lead hazards, provides for the conduct of a lead risk assessment (see Note 1).Note 1--A lead risk assessment, as defined by Federal regulation (40CFR745.227(d)), includes, as part of the reporting process, a description of interim controls and abatement options for each identified lead hazard and a suggested prioritization for addressing each hazard. This guide provides for the identification of lead hazards and the prioritization for addressing each hazard guidance on the determination of appropriate interim controls and abatement options for each identified lead hazard is beyond the scope of this guide and is included in a companion standard. Guidance on the determination of appropriate interim controls and abatement options for each identified lead hazard is beyond the scope of this guide and is the subject of a standard under development by E06.23.1.2 This guide is insufficient as the sole means to determine causes of lead poisoning in young children having an elevated blood lead level (EBL). In these cases, procedures including investigation of the total living environment of the child and a pediatric medical evaluation is needed. Reference should be made to Preventing Childhood Lead Poisoning (CDC, 1991), the Guidelines for the Evaluation and Control of Lead-Based Paint Hazards in Housing (HUD, 1997), and Screening Young Children for Lead Poisoning (CDC, 1997).1.3 The values stated in SI units are to be regarded as the standard.1.4 This standard does not purport to address all of the safety concerns, if any, associated with its use.

1.1 These test methods describe the evaluation of the total sulfation activity in the atmosphere. Because of its oxidizing power, lead dioxide (PbO2) converts not only sulfur dioxide (SO2), but other compounds, such as mercaptans and hydrogen sulfide, into sulfate. It fixes sulfur trioxide and sulfuric acid mist present in the atmosphere (see Note). 1.2 Test Method A describes the use of a PbO2 candle, and Test Method B describes that of a PbO2 sulfation plate. 1.3 These test methods provide a weighted average effective SO2 level for a 30-day interval. 1.4 The results of these test methods correlate approximately with volumetric SO2 concentrations, although the presence of dew or condensed moisture tends to enhance the capture of SO2 onto the candle or plate. 1.5 The values stated in SI units shall be regarded as the standard. The values given in parentheses are for information only and may be approximate. Note-It has been shown that the rate constant of the chemical reaction between SO2 and PbO2 is independent of the concentration of SO2 up to levels of 1000 ppm, if 15% or less of the PbO2 has been reduced (1). 15% of the PbO2 is equivalent to 11 to 12 mg of SO2/cm per day. 1.6 This standard does not purport to address all of the safety problems, if any, associated with its use.

1.1 This practice is intended to assist in the selection of sorbents and procedures for the sampling and analysis of ambient (Ref 1), indoor (2) and the workplace (3) atmospheres for a variety of common volatile organic compounds (VOCs). It may also be used for measuring emissions from materials in small or full scale environmental chambers or for human exposure assessment. 1.2 A complete listing of VOCs for which this practice has been tested, at least over part of the measurement range (1.5), is shown in Tables 1-6. For other compounds this practice shall be tested according to EN 1076 or other appropriate validation protocols (Sections 13 and 14). (4,1) 1.3 This practice is based on the sorption of VOCs from air onto selected sorbents for combinations of sorbents. Sampled air is pulled through a tube containing these sorbents. The sorbed VOCs are subsequently recovered by thermal desorption and analyzed by capillary gas chromatography. 1.4 This practice recommends a number of sorbents that can be packed in sorbent tubes, for use in the sampling of a wide range of different volatile organic compounds, in the range 0 to 400176C (v.p. 15 to 0.01 kPa at 25176C). Single-bed tubes containing for example sorbent Type A3,4 are appropriate for normal alkanes from n-C6(hexane) to n-C10(decane) and substances with similar volatility (v.p. 15 to 0.3 kPa at 25176C). More volatile materials should be sampled on stronger sorbents, such as sorbent Type B3,5. Other sorbent types than those specified may be used, if their breakthrough capacities are adequate and their thermal desorption blanks are sufficiently small. Examples are given in Appendix X2. A broader range of VOCs may be sampled using multi-bed tubes 1.5 This practice can be used for the measurement of airborne vapors of these volatile organic compounds in a concentration range of approximately 0.1 ug/m3 to 1g/m3, for individual organic compounds in 1-10 L air samples. The method is also suitable for the measurement of the airborne concentrations of individual components of volatile organic mixtures, provided that the total loading of the mixture does not exceed the capacity of the tube. Quantitative measurements are possible when using validated procedures with appropriate quality assurance measures. 1.5.1 The upper limit of the useful range is set by the sorptive capacity of the sorbent used, and by the linear dynamic range of the gas chromatograph, column and detector, or by the sample splitting capability of the analytical instrumentation used. The sorptive capacity is measured as a breakthrough volume of air, which determines the maximum air volume that must not be exceeded when sampling. 1.5.2 The lower limit of the useful range depends on the noise level of the detector and on blank levels of analyte or interfering artifacts, or both, on the sorbent tubes. 1.5.3 Artifacts are typically

Atmospheric corrosion of metallic materials is a function of many weather and atmospheric variables. The effect of specific corrodants, such as sulfur dioxide, can accelerate the atmospheric corrosion of metals significantly. The sulfation plate method provides a simple technique to independently monitor the level of SO2 in the atmosphere to yield a weighted average result. Sulfation plate results may be used to characterize atmospheric corrosion test sites regarding the effective average level of SO2 in the atmosphere at these locations. Sulfation plate testing is useful in determining microclimate, seasonal, and long term variations in the effective average level of SO2. The results of sulfation plate tests may be used in correlations of atmospheric corrosion rates with atmospheric data to determine the sensitivity of the corrosion rate to SO2 level. The sulfation plate method may also be used with other methods to characterize the atmosphere at sites where buildings or other construction is planned in order to determine the extent of protective measures required for metallic materials.1.1 This practice covers a weighted average effective SO2 level for a 30-day interval through the use of the sulfation plate method, a technique for estimating the effective SO2 content of the atmosphere, and especially with regard to the atmospheric corrosion of stationary structures or panels. This practice is aimed at determining SO2 levels rather than sulfuric acid aerosol or acid precipitation. 1.2 The results of this practice correlate approximately with volumetric SO2 concentrations, although the presence of dew or condensed moisture tends to enhance the capture of SO2 into the plate. 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 and health practices and determine the applicability of regulatory limitations prior to use.

1.1 This practice covers procedures for evaluating the following performance characteristics of air quality measurement methods: bias (in part only), calibration function and linearity, instability, lower detection limit, period of unattended operation, selectivity, sensitivity, and upper limit of measurement.1.2 The procedures presented in this practice are applicable only to air quality measurement methods with linear continuous calibration functions, and the output variable of which is a defined time average. The linearity may be due to postprocessing of the primary output variable. Additionally, replicate values belonging to the same input state are assumed to be normally distributed. Components required to transform the primary measurement method output into the time averages desired are regarded as an integral part of this measurement method.1.3 For surveillance of measurement method stability under routine measurement conditions, it may suffice to check the essential performance characteristics using simplified tests, the degree of simplification acceptable being dependent on the knowledge on the invariance properties of the performance characteristics previously gained by the procedures presented here.1.4 There is no fundamental difference between the instrumental (automatic) and the manual (for example, wet-chemical) procedures, as long as the measured value is an average representative for a predefined time interval. Therefore, the procedures presented are applicable to both. Furthermore, they are applicable to measurement methods for ambient, workplace, and indoor atmospheres, as well as emissions.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 and health practices and determine the applicability of regulatory limitations prior to use.
