ISO 16702:2001 工作场所空气质量 用2-（1-甲氧基）酸呱嗪和液相色谱法测定空气中的总异氰酸盐

This International Standard gives general guidance for the sampling and analysis of airborne organic isocyanates in workplace air, using the 2-(1-methoxyphenyl) piperazine reagent and liquid chromatography. This International Standard is applicable to the measurement of a wide range of organic compounds containing isocyanate functional groups (NCO), including isocyanate monomers and prepolymers. This International Standard is applicable to the measurement of any product containing free isocyanate groups. This International Standard is applicable to the measurement of time-weighted-average concentrations of organic isocyanates in workplace atmospheres, and for sampling over periods in the range 10 min to 8 h. It is designed for personal monitoring, but may also be used for fixed-location monitoring by suitable modification. This International Standard is applicable to the measurement of airborne organic isocyanates in the concentration range approximately 0,1 μg NCO·mto 140 μg NCO·m for a 15 I sample volume. The qualitative and quantitative detection limits for isocyanate, defined as three times and ten times the standard deviation of six blank determinations, have been found to be typically around 0,001 μg NCO and 0,004 μg NCO per sample respectively (electrochemical detection). For a 15 I air sample, these values correspond to qualitative and quantitative detection limits of 0,07 μg·m and 0,3 μg·m respectively. EXAMPLES Aromatic monomers include toluene diisocyanate (TDI) and methylene bis(4-phenyl isocyanate) (4,4-diisocyanatodiphenylmethane, MDI). Aliphatic monomers include isophorone diisocyanate (IPDI) and 1,6-hexamethylene diisocyanate (HDI). Isocyanate oligomers or prepolymers are derived from these monomers by self-condensation or reaction with polyols. NOTE 1 Organic isocyanates can also arise from thermal decomposition of polyurethanes. If both isocyanates and amines are believed to be present, use of a standard which enables the simultaneous determination of both amines and isocyanates may be more appropriate (ISO method in draft). An alternative procedure using the MAP [1-(9-anthracenylmethyi)piperazine] reagent is also available (ISO method in draft). NOTE 2 The objective of air monitoring is usually to determine worker exposure and, therefore, the procedures described in this International Standard are for personal sampling in the breathing zone. The procedures may be used for background or fixed location sampling. However, it should be recognized that, due to aerodynamic effects, samplers designed for personal sampling do not necessarily exhibit the same collection characteristics when used for other purposes.

ANSI/ASTM D6061:2001 呼吸式气溶胶采样器性能评价惯例

This practice covers the evaluation of the performance of personal samplers of non-fibrous respirable aerosol. The samplers are assessed relative to a specific respirable sampling convention. The convention is one of several that identify specific particle size fractions for assessing health effects of airborne particles. When a health effects assessment has been based on a specific convention it is appropriate to use that same convention for setting permissible exposure limits in the workplace and ambient environment and for monitoring compliance. The conventions, which define inhalable, thoracic, and respirable aerosol sampler ideals, have now been adopted by the International Standards Organization (Technical Report ISO TR 7708), the Comit Europen de Normalisation (CEN Standard EN 481), and the American Conference of Governmental Industrial Hygienists (ACGIH, Ref (1)), developed (2) in part from health-effects studies reviewed in Ref (3) and in part as a compromise between definitions proposed in Refs (3, 4). This practice is complimentary to Test Method D 4532, which specifies a particular instrument, the 10-mm cyclone. The sampler evaluation procedures presented in this practice have been applied in the testing of the 10-mm cyclone as well as the Higgins-Dewell cyclone. Details on the evaluation have been recently published (5-7) and can be incorporated into revisions of Test Method D 4532. A central aim of this practice is to provide information required for characterizing the uncertainty of concentration estimates from samples taken by candidate samplers. For this purpose, sampling accuracy data from the performance tests given here can be combined with information as to analytical and sampling pump uncertainty obtained externally. The practice applies principles of ISO GUM, expanded to cover situations common in occupational hygiene measurement, where the measurand varies markedly in both time and space. A general approach (8) for dealing with this situation relates to the theory of tolerance intervals and may be summarized as follows: Sampling/analytical methods undergo extensive evaluations and are subsequently applied without re-evaluation at each measurement, while taking precautions (for example, through a quality assurance program) that the method remains stable. Measurement uncertainty is then characterized by specifying the evaluation confidence (for example, 95 %) that confidence intervals determined by measurements bracket measurand values at better than a given rate (for example, 95 %). Moreover, the systematic difference between candidate and idealized aerosol samplers can be expressed as a relative bias, which has proven to be a useful concept and is included in the specification of accuracy (3.2.3-3.2.10). Units of the International System of Units (SI) are used throughout this practice and should be regarded as standard. 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.

ASTM D6735-01 矿物煅烧排气源中测量气态氯化物和氟化物的标准试验方法.冲击法

This field-test method provides chloride and fluoride concentration results on a dry basis. Concentration data for gaseous chlorides and fluorides are assumed to be hydrochloric acid gas, and hydrofluoric acid gas when calculating mass emission rates. Mass emission rates of HCl and HF can be calculated if the effluent volumetric flow rate is known. Volumetric flow rates can be calculated by conducting EPA Methods 1–4 or their equivalents. This field test method provides data having bias and precision for HCl consistent with the values in Section 14. In addition, the test-specific bias can be assessed for each test by conducting the post-test quality assurance check. The procedure is identified as optional, and the performance of this procedure depends on the test specific data quality objectives, and end use of the data. The test-specific precision may be determined by conducting paired-runs. Paired runs aid in identifying possible suspect data and provide backup in the event one train is invalidated. Performing paired runs depends on the test-specific data quality objectives. The reaction of gaseous HCl with ammonia (NH3) to form solid ammonium chloride (NH4Cl) is well known. At stack temperatures common to the exits of baghouses and ESPs at mineral calcining facilities (that is, 250 to 450°F or 121 to 232°C), an equilibration between the gaseous HCl/NH3, the condensed NH4Cl(s), and the effluent particulate matter can exist. It is impossible to know the exact partition ratio between the gas and particulate phases of these compounds in the sampling system. Furthermore, it is very difficult to control the effects of these partitioning reactions within the various sampling system components. Note 48212;Use of this method is cautioned when trying to quantify HCl (g) in the presence of ammonium chloride and ammonia.1.1 This method will measure the concentration of gaseous hydrochloric and hydrofluoric acids, and other gaseous chlorides and fluorides that pass through a particulate matter filter maintained at 177176;C (350176;F). This method is specific for sampling combustion effluent from mineral calcining industries and other stationary sources where the reactive/adsorptive nature of the particulate matter may affect measurements.1.2 This method utilizes ion chromatography to quantify the aqueous samples, and thus measures only the C1- and F - ions.1.3 Based on a one-hour sampling run, the method will provide results of known accuracy and precision for chloride and fluoride in-stack concentrations of 0.5 ppm (v) dry or greater. Extending the run duration and sampling a greater volume of effluent will extend the range to lower concentrations.1.4 This method includes optional post-test quality assurance procedures to assess the bias of the test results, and optional paired sample train runs to assess the precision of test results.

This practice is significant for determining performance relative to ideal sampling conventions. The purposes are multifold: 5.1.1 The conventions have a recognized tie to health effects and can easily be adjusted to accommodate new findings. 5.1.2 Performance criteria permit instrument designers to seek practical sampler improvements. 5.1.3 Performance criteria promote continued experimental testing of the samplers in use with the result that the significant variables (such as wind speed, particle charge, etc.) affecting sampler operation become understood. One specific use of the performance tests is in determining the efficacy of a given candidate sampler for application in regulatory sampling. The accuracy of the candidate sampler is measured in accordance with the evaluation tests given here. A sampler may then be adopted for a specific application if the accuracy is better than a specific value. 5.2.1 Discussion151;In some instances, a sampler so selected for use in compliance determinations is specified within an exposure standard. This is done so as to eliminate differences among similar samplers. Sampler specification then replaces the respirable sampling convention, eliminating bias (3.2.10), which then does not appear in the uncertainty budget. Although the criteria are presented in terms of accepted sampling conventions geared mainly to compliance sampling, other applications exist as well. For example, suppose that a specific aerosol diameter-dependent health effect is under investigation. Then for the purpose of an epidemiological study an aerosol sampler that reflects the diameter dependence of interest is required. Sampler accuracy may then be determined relative to a modified sampling convention.1.1 This practice covers the evaluation of the performance of personal samplers of non-fibrous respirable aerosol. The samplers are assessed relative to a specific respirable sampling convention. The convention is one of several that identify specific particle size fractions for assessing health effects of airborne particles.

1.1 This test method covers the sampling/analysis of nicotine and 3-ethenylpyridine (3-EP) in indoor air. This test method is based upon the collection of nicotine and 3-EP by adsorption on a sorbent resin, extraction of nicotine and 3-EP from the sorbent resin, and determination by gas chromatography (GC) with nitrogen selective detection. (1) 1.2 The active samplers consist of an XAD-4 sorbent tube attached to a sampling pump. This test method is applicable to personal or area sampling.1.3 This test method is limited in sample duration by the capacity of the XAD-4 tube for nicotine (about 300 g). This test method has been evaluated up to 24-h sample duration; however, samples are typically acquired for at least 1 h (sometimes only 1 h). (2)1.4 For this test method, limits of detection (LOD) and quantitation (LOQ) for nicotine at a sampling rate of 1.5 L/min are, respectively, 0.11 g/m3 and 0.37 g/m3 for 1-h sample duration and 0.01 g/m3 and 0.05 g/m3 for 8-h sample duration. The LOD and LOQ for 3-EP at a sampling rate of 1.5 L/min are, respectively, 0.06 g/m3 and 0.19 g/m3 for 1-h sample duration and 0.01 g/m3 and 0.02 g/m3 for 8-h sample duration (2). Both LOD and LOQ can be reduced by increasing the sensitivity of the thermionic specific detector.1.5 The values stated in SI units are to be regarded as standard.This standard does not purport to address all of the safety concerns, if any, associated with its use.

Some chemical constituents of AWD are not stable and must be preserved before chemical analysis. Without sample preservation, it is possible that analytes can be lost through decomposition or sorption to the storage bottles. Contamination of AWD samples can occur during both sample preservation and sample storage. Proper selection and cleaning of sampling containers are required to reduce the possibility of contamination of AWD samples. The natural sponge and talc-free plastic gloves used in the following procedures should be recognized as potential sources of contamination. Individual experience should be used to select products that minimize contamination.1.1 This guide presents recommendations for the cleaning of plastic or glass materials used for collection of atmospheric wet deposition (AWD). This guide also presents recommendations for the preservation of samples collected for chemical analysis. 1.2 The materials used to collect AWD for the analysis of its inorganic constituents and trace elements should be plastic. High density polyethylene (HDPE) is most widely used and is acceptable for most samples including samples for the determination of the anions of acetic, citric, and formic acids. Borosilicate glass is a collection alternative for the determination of the anions from acetic, citric, and formic acid; it is recommended for samples for the determination of other organic compounds. 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.
