BS ISO 16362:2005 环境空气.高效液体色谱法测定粒子相位多环芳烃

This International Standard specifies sampling, clean-up and analysis procedures for the quantitative determination of low volatility (particle-bound) polycyclic aromatic hydrocarbons (PAHs) in ambient air. For sampling, a low-volume or a medium/high-volume sampling device may be used. Sampling times between 1 h and 24 h are possible. The sampling volume flowrates can range from 1 m/h to 4 m/h ("low volume sampler") or from 10 m/h to about 90 m/h ("medium/high-volume sampler"). In any case, the linear face velocity at the collection filter should range between about 0,5 m/s and 0,9 m/s. The method has been validated for sampling periods up to 24 h. The detection limits for single PAHs and the standard deviations resulting from duplicate measurements are listed in 9.2 and Annex D respectively. This International Standard describes a sampling and analysis procedure for PAH that involves collection from air onto a filter followed by analysis using high performance liquid chromatography usually with fluorescence detector (FLD). The use of a diode array detector (DAD) is possible. The combination of both detector types is also possible (see Annex B). Total suspended particulate matter is sampled. Generally, compounds having a boiling point above 430 ℃ (vapour pressure less than 10 kPa at 25 ℃, e.g. chrysene, benz[a]anthracene) can be collected efficiently on the filter at low ambient temperatures (e.g. below 10 ℃). In contrast, at higher temperatures (above 30 ℃, see also ISO 12884), only PAHs having boiling points above 475 ℃ (vapour pressure less than 10kPa at 25 ℃) are determined quantitatively (see Annex F).

BS ISO 16000-1:2005 室内空气.抽样方法的一般情况

This standard is intended to aid the planning of indoor pollution monitoring. Before a sampling strategy is devised for indoor air monitoring, it is necessary to clarify for what purposes, when, where, how often and over what periods of time monitoring is to be performed. The answers to these questions depend, in particular, on a number of special characteristics of the indoor environments, on the objective of the measurement and, finally, on the environment to be measured. ISO 16000-1:2004 deals with the significance of these factors and offers suggestions on how to develop a suitable sampling strategy. ISO 16000-1:2004 is applicable to indoor environments such as dwellings having living rooms, bedrooms, do-it-yourself rooms, recreation rooms and cellars, kitchens and bathrooms; workrooms or work places in buildings which are not subject to health and safety inspections in regard to air pollutants (for example, offices, sales premises); public buildings (for example hospitals, schools, kindergartens, sports halls, libraries, restaurants and bars, theatres, cinemas and other function rooms), and also cabins of vehicles.

This part of IS0 16000 specifies a diffusive sampler/solvent desorption/high performance liquid chromatography (HPLC) method for the determination of formaldehyde in indoor air. The test method is applicable to the measurement of formaldehyde in indoor air over the range from 0,001 mg/m to 1,0 mg/m for a sampling period of between 24 h and 72 h. For sampling periods of 24 h, the applicable concentration range is 0,003 mg/m to 1 mg/m, and for 72 h it is 0,001 mg/m to 0,33 mg/m. The method is suitable for measurements in atmospheres of up to 80 % relative humidity and for monitoring at air velocities as low as 0,02 m/s. Potential interferences, including those due to the presence of other carbonyl compounds, should be eliminated by the chromatographic step in the method. The sampling method gives a time-weighted average result. note: 1) Instead of the nomenclature according to IUPAC regulations (e.g. methanal), the more common names (e.g. formaldehyde) are used in this part of ISO 16000.

This International Standard specifies a method for the determination of the time-weighted average mass concentration of hexavalent chromium in workplace air. Separate sample preparation methods are specified for the extraction of soluble and insoluble hexavalent chromium. The method for insoluble hexavalent chromium can also be used to prepare samples for determination of total hexavalent chromium, if desired. This International Standard is applicable to the personal sampling of the inhalable fraction of airborne particles, as defined in ISO 7708, and to static (area) sampling. The analytical method is applicable to the determination of masses of 0,01 μg to 10 μg of hexavalent chromium per sample, without dilution. The concentration range of hexavalent chromium in air for which the measuring procedure is applicable is determined by the sampling method selected by the user (see 10.1). For a 1 m3 air sample, without sample dilution, the working range is approximately 0,01 μg⋅m−3 to 10 μg⋅m−3.

ASTM D4947-05 室内气体中氯丹和庚氯残留物的标准试验方法

This test method is intended to be used primarily for non-occupational exposure monitoring in domiciles, public access buildings and offices. Chlordane has been used widely as a general insecticide for crops (for example, cotton) and as a termiticide. Heptachlor is a major component of technical chlordane and an insecticide in its own right. Although their use in the United States was discontinued in 1988, residues of the chemicals may remain in indoor air for many years after application.1.1 This test method covers the sampling and analysis of indoor atmospheres for residues of chlordane and heptachlor.1.2 This test method is based upon the collection of chlordane and heptachlor from air onto polyurethane foam (PUF) and analysis by gas chromatography coupled with electron capture detection.1.3 This test method is applicable to concentrations of chlordane varying from 0.1 to 100 g/m3 and heptachlor varying from 0.01 to 80.0 g/m3 with sampling periods to collect at least 0.25 m3 of air. Detection limits will depend upon the conditions of the gas chromatography (GC) and the length of the sampling period.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.

Standard Test Methods for Atmospheric Leaks Using a Thermal Conductivity Leak Detector

ASTM D6995-05 基于最大混合比重(Gmm)的VMA域测量的标准试验方法

Various users desire indication of compliance with VMA specifications for hot mix asphalt (HMA) during production. The standard practice for determining VMA requires that the bulk specific gravity of the aggregate components be determined. This is a very time consuming test, which is not suitable for routine QC procedures. When an aggregate source used in the mix has a highly variable bulk specific gravity and a reference average bulk specific gravity (Gsb) (for example, as established in the mix design) is used to calculate VMA during HMA production, erroneous values may occur. The test for maximum specific gravity of the mix (Gmm) is a routine QC test at HMA plants. The effective specific gravity of the aggregate components (Gse) can be easily calculated from this test. However the Gse does not take into account the amount of asphalt absorbed, which is required for accurate VMA determination. This method provides a means to correct the Gse to account for the average absorbed asphalt. This procedure should not be used if the percent water absorption of the total (combined) aggregates varies between four tests, randomly obtained over a 30 day period, by more than 0.4 %.1.1 This test method is intended to be used for a rapid field determination of voids in mineral aggregate (VMA) of hot mix asphalt (HMA). It provides equations for calculating the VMA based on the asphalt content of the mix and its maximum specific gravity (Gmm). It is intended that this should be used for the rapid "field" determination of VMA during Quality Control (QC) operations at HMA plants, particularly where the specific gravity of the aggregate is highly variable.1.2 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 D6831-05a 利用惯性微量天平在烟囱内取样并测定烟气中颗粒物质的标准试验方法

The measurement of particulate matter is widely performed to characterize emissions from stationary sources in terms of total emission rates to the atmosphere for regulatory purposes. This test method is particularly well suited for use in performance assessment and optimization of particulate matter control systems, continuous particulate matter emissions monitoring systems and the measurement of low concentration particulate matter laden gas streams in the range of 0.2 mg/m3 to 50 mg/m3.1.1 This test method describes the procedures for determining the mass concentration of particulate matter in gaseous streams using an automated, in-stack test method. This method, an in-situ, inertial microbalance, is based on inertial mass measurement using a hollow tube oscillator. This method is describes the design of the apparatus, operating procedure, and the quality control procedures required to obtain the levels of precision and accuracy stated.1.2 This method is suitable for collecting and measuring filterable particulate matter concentrations in the ranges 0.2 mg/m3 and above taken in effluent ducts and stacks.1.3 This test method may be used for calibration of automated monitoring systems (AMS). If the emission gas contains unstable, reactive, or semi-volatile substances, the measurement will depend on the filtration temperature, and this method (and other in-stack methods) may be more applicable than out-stack methods for the calibration of automated monitoring systems.1.4 This test method can be employed in sources having gas temperature up to 200C and having gas velocities from 3 to 27 m/s.1.5 This test method includes a description of equipment and methods to be used for obtaining and analyzing samples and a description of the procedure used for calculating the results.1.6 Stack temperatures limitation for this test method is approximately 200C (392F).1.7 This test method may be also be limited from use in sampling gas streams that contain fluoride, or other reactive species having the potential to react with or within the sample train.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 and health practices and determine the applicability of regulatory limitations prior to use.

ASTM D7169-05 用高温气相色谱法测定带有类似原油和大气以及真空残留物的样品的沸点分布的标准试验方法

The determination of the boiling point distribution of crude oils and vacuum residues, as well as other petroleum fractions, yields important information for refinery operation. These boiling point distributions provide information as to the potential mass percent yield of products. This test method may provide useful information that can aid in establishing operational conditions in the refinery. Knowledge of the amount of residue produced is important in determining the economics of the refining process.1.1 This test method covers the determination of the boiling point distribution and cut point intervals of crude oils and residues by using high temperature gas chromatography. The amount of residue (or sample recovery) is determined using an external standard.1.2 This test method extends the applicability of simulated distillation to samples that do not elute completely from the chromatographic system. This test method is used to determine the boiling point distribution through a temperature of 720C. This temperature corresponds to the elution of n-C100.1.3 This test method is used for the determination of boiling point distribution of crude oils. This test method uses capillary columns with thin films, which results in the incomplete separation of C 4-C8 in the presence of large amounts of carbon disulfide, and thus yields an unreliable boiling point distribution corresponding to this elution interval. In addition, quenching of the response of the detector employed to hydrocarbons eluting during carbon disulfide elution, results in unreliable quantitative analysis of the boiling distribution in the C 4-C8 region. Since the detector does not quantitatively measure the carbon disulfide, its subtraction from the sample using a solvent-only injection and corrections to this region via quenching factors, results in an approximate determination of the net chromatographic area. A separate, higher resolution gas chromatograph (GC) analysis of the light end portion of the sample may be necessary in order to obtain a more accurate description of the boiling point curve in the interval in question (see ).1.4 This test method is also designed to obtain the boiling point distribution of other incompletely eluting samples such as atmospheric residues, vacuum residues, etc., that are characterized by the fact that the sample components are resolved from the solvent.1.5 This test method is not applicable for the analysis of materials containing a heterogeneous component such as polyesters and polyolefins.1.6 The values stated in SI units are to be regarded as the standard. The values given in parentheses are for information only.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. Specific warning statements are given in Section 8.

This practice is recommended for use primarily for non-occupational exposure monitoring in domiciles, public access buildings, and offices. The methods described in this practice have been successfully applied to measurement of pesticides and PCBs in outdoor air and for personal respiratory exposure monitoring. A broad spectrum of pesticides are commonly used in and around the house and for insect control in public and commercial buildings.

This part of ISO 15202 is applicable for the assessment of workplace exposure to metals and metalloids for comparison with limit values (see e.g. EN 689[1], ASTM E 1370[2], etc.). The following is a non-exclusive list of metals and metalloids for which limit values have been set (see Reference [3]), and for which one or more of the sample dissolution methods specified in ISO 15202-2 and the analytical procedure described in this part of ISO 15202 are applicable. However, there is no information available on the effectiveness of any of the sample dissolution methods specified in ISO 15202-2 for those elements in italics. aluminium calcium magnesium selenium tungsten antimony chromium manganese silver uranium arsenic cobalt mercury sodium vanadium barium copper molybdenum strontium yttrium beryllium hafnium nickel tantalum zinc bismuth indium phosphorus tellurium zirconium boron iron platinum thallium caesium lead potassium tin cadmium lithium rhodium titanium NOTE ISO 15202 is not applicable to determination of elemental mercury, since mercury vapour is not collected using the sampling method specified in ISO 15202-1. The procedure is suitable for assessment of exposure against the long-term exposure limits for most of the metals and metalloids listed above when sampling at a typical flow rate of 2 lmin for sampling times in the range 30 min to 8 h and for assessment of exposure against the short-term exposure limits, where applicable (see 10.4). The procedure suffers from no significant spectral interferences (see 10.5), provided that suitable analytical wavelengths are used. However, inaccurate background correction and/or inadequate matrix-matching can adversely affect results.
