ASTM D6785-02 用火焰或石墨炉原子吸收光谱法测定工作场所空气中铅含量的标准试验方法

1.1 This standard specifies flame and graphite furnace atomic absorption spectrometric methods for the determination of the time-weighted average mass concentration of particulate lead and lead compounds in workplace air.1.2 The method is applicable to personal sampling of the inhalable fraction of airborne particles, as defined in ISO 7708, and to static (area) sampling.1.3 The sample dissolution procedure specifies hot plate or microwave digestion, or ultrasonic extraction (11.2). The sample dissolution procedure is not effective for all lead compounds (see Section 5). The use of an alternative, more vigorous dissolution procedure is necessary when it is desired to extract lead from compounds present in the test atmosphere that are insoluble using the dissolution procedures described herein. For example if it is desired to determine silicate lead, a hydrofluoric acid dissolution procedure is required.1.4 The flame atomic absorption method is applicable to the determination of masses of approximately 1 to 200 956;g of lead per sample, without dilution (1). The graphite furnace atomic absorption method is applicable to the determination of masses of approximately 0.01 to 0.5 956;g of lead per sample, without dilution (1).1.5 The ultrasonic extraction procedure has been validated for the determination of masses of approximately 20 to 100 956;g of lead per sample, for laboratory-generated lead fume air filter samples (2).1.6 The concentration range for lead in air for which this procedure is applicable is determined in part by the sampling procedure selected by the user (see Section 10).1.7 Anions that form precipitates with lead may interfere, but this potential interference is overcome by the addition of the disodium salt of ethylenediamine tetraacetic acid (EDTA) when necessary.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 D5156-02(2008) 周围环境,工作地点及室内空气中臭氧连续测量的标准试验方法

Standards for O3 in the atmosphere have been promulgated by government authorities to protect the health and welfare of the public (5) and also for the protection of industrial workers (6). Although O3 itself is a toxic material, in ambient air it is primarily the photochemical oxidants formed along with O3 in polluted air exposed to sunlight that cause smog symptoms such as lachrymation and burning eyes. Ozone is much more easily monitored than these photochemical oxidants and provides a good indication of their concentrations, and it is therefore the substance that is specified in air quality standards and regulations.1.1 This test method describes the sampling and continuous analysis of ozone (O3) in the atmosphere at concentrations ranging from 10 to 2000 μg/m3 of O3 in air (5 ppb(v) to 1 ppm(v)). 1.1.1 The test method is limited to applications by its sensitivity to interferences as described in Section 6. The interference sensitivities may limit its use for ambient and workplace atmospheres. 1.2 The values stated in SI units are to be regarded as the standard. 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.

ASTM D5149-02(2008) 大气臭氧浓度的标准试验方法:化学发光乙烯的连续测量

Air quality standards for ozone have been promulgated by government authorities to protect the health and welfare of the public. Though ozone itself is a toxic material, it is often complex organic compounds that cause the symptoms of smog such as tearing and burning eyes. However, ozone is the predominant oxidant and is much more easily monitored than organic species. Since ozone concentrations are also correlated with other photochemical oxidant levels, it is the substance that is specified in air quality standards and regulations.1.1 This test method describes the sampling and continuous analysis of the ozone content of the atmosphere at concentrations of 20 to 2000 μg of ozone/m3 (10 ppb (v) to 1 ppm (v)). 1.2 This test method is limited in application by its sensitivity to interferences as described below. This test method is not suitable for personal sampling because of instrument size and sensitivity to vibration and ambient temperature. 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. Some specific precautionary statements are presented in Section 8.

ASTM D5955-02 基于粒子紫外线吸收法（UVPM）和粒子荧光吸收法（FPM）评估环境烟草烟雾对可吸入悬浮颗粒物影响的标准试验方法

1.1 These test methods pertain to the sampling/analysis of respirable suspended particles (RSP) and the estimation of the RSP fraction attributable to environmental tobacco smoke (ETS). These test methods are based on collection of total RSP on a membrane filter, extracting the collected material in methanol, and measuring total ultraviolet absorbance or fluorescence, or both, of this extract. The corresponding methods of estimation are termed ultraviolet particulate matter (UVPM) and fluorescent particulate matter (FPM), respectively.1.2 These test methods are compatible with, but do not require the determination of solanesol, which is also used to estimate the contribution of ETS to RSP (see Test Method D 6271).1.3 The sampling components consist of a preweighed, 1.0-m pore size polytetrafluoroethylene (PTFE) membrane filter in a filter cassette connected on the inlet end to a particle size separating device and, on the outlet end, to a sampling pump. These test methods are applicable to personal and area sampling.1.4 These test methods are limited in sample duration only by the capacity of the membrane filter (about 2000 g). These test methods have been evaluated up to a 24-h sample duration with a minimum sample duration of at least 1 h.1.5 Limits of detection (LOD) and quantitation (LOQ) for the UVPM test method at a sampling rate of 2 L/min are, respectively, 2.5 g/m3 and 8.3 g/m3 for a 1-h sample duration and 0.3 g/m3 and 1.0 g/m3 for an 8-h sample duration. The LOD and LOQ for the FPM test method at a sampling rate of 2 L/min are, respectively, 1.4 956;g/m3 and 4.7 956;g/m 3 for a 1-h sample duration and 0.2 956;g/m3 and 0.6 956;g/m 3 for an 8-h sample duration.1.6 The values stated in SI units are to be regarded as standard.1.7 This standard does not purport to address all of the safety concerns, if any, associated with its use.

ASTM D5015-02 电测法测定大气湿沉积物样品pH值的标准试验方法

The accurate measurement of pH in atmospheric wet deposition is an essential and critically important component in the monitoring of atmospheric wet deposition for trends in the acidity and overall air quality. Atmospheric wet deposition is, in general, a low ionic strength, unbuffered solution. Special precautions, as detailed in this test method, are necessary to ensure accurate pH measurements (1).3 Special emphasis must be placed on minimizing the effect of the residual liquid junction potential bias. This test method is applicable only to the measurement of pH in atmospheric wet deposition. Its use in other applications may result in inaccuracies. Fig. 1 provides a frequency distribution of precipitation pH values measured in conjunction with a national monitoring program within the United States. These data are an indication of the range of pH values common to atmospheric wet deposition. FIG. 1 Frequency Distribution of Measured Laboratory pH of Atmospheric Wet Deposition From the 1984 National Atmospheric Deposition Program (NADP)/National Trends Network (NTN)1.1 This test method is applicable to the determination of pH in atmospheric wet deposition samples by electrometric measurement using either a pH half cell with a reference probe or a combination electrode as the sensor. 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.

The document gives general guidance for the sampling and analysis of volatile organic compounds (VOCs) in air. It is applicable to ambient, indoor and workplace atmospheres. It is appropriate for the determination of a wide range of VOCs, including hydrocarbons, halogenated hydrocarbons, esters, glycol ethers, ketones and alcohols. A number of sorbents are recommended for the sampling of these VOCs, each sorbent having a different range of applicability. It is applicable to the measurement of airborne vapours of VOCs in a concentration range of approximately 0,5 ?m bis 100 mg/m individual compound.

This part of ISO 16017 gives general guidance for the sampling and analysis of volatile organic compounds (VOCs) in air. It is applicable to ambient, indoor and workplace atmospheres and the assessment of emissions from materials in small- or full-scale test chambers. This part of ISO 16017 is appropriate for a wide range of VOCs, including hydrocarbons, halogenated hydro-carbons, esters, glycol ethers, ketones and alcohols. A number of sorbents are recommended for the sampling of these VOCs, each sorbent having a different range of applicability. Very polar compounds will generally require derivatization, very low boiling compounds will only be partially retained by the sorbents, depending on ambient temperature, and can only be estimated qualitatively. Semi-volatile compounds will be fully retained by the sorbents, but may only be partially recovered. Compounds for which this part of ISO 16017 has been tested are given in tables. This part of ISO 16017 may be applicable to compounds not listed, but in these cases it is advisable to use a back-up tube containing the same or a stronger sorbent. This part of ISO 16017 is applicable to the measurement of airborne vapours of VOCs in a concentration range of approximately 0,5 μg/ m to 100 mg/m individual compound. 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 shall not be exceeded when sampling. The lower limit of the useful range depends on the noise level of the detector and on blank levels of analyte and/or interfering artefacts on the sorbent tubes. Artefacts are typically sub-nanogram for well-conditioned Tenax GR and carbonaceous sorbents such as Carbopack/Carbotrap type materials, carbonized molecular sieves and molecular sieves such as Spherocarb, or pure charcoal; at low nanogram levels for Tenax TA and at 5 ng to 50 ng levels for other porous polymers such as Chromosorbs and Porapaks. Sensitivity is typically limited to 0,5 ug/m3 for 10-litre air samples with this latter group of sorbents because of their inherent high background. The procedure specified in this part of ISO 16017 is applicable to low flowrate personal sampling pumps and gives a time-weighted average result. It is not applicable to the measurement of instantaneous or short-term fluctuations in concentration. note:1) The sorbents listed in annex C and elsewhere in this International Standard are those known to perform as specified under this part of ISO 16017. Each sorbent or product that is identified by a trademarked name is unique and has a sole manufacturer; however, they are widely available from many different suppliers. This information is given for the convenience of users of this part of ISO 16017 and does not constitute an endorsement by ISO of the product named. Equivalent products may be used if they can be shown to lead to the same results.

This part of ISO 16000 describes a procedure for the determination of formaldehyde (HCHO) and other carbonyl compounds (aldehydes and ketones) in air. The method is specific for formaldehyde but, with modification, at least thirteen other carbonyl compounds can be detected and quantified. It is suitable for determination of formaldehyde and other carbonyl compounds in the concentration range of approximately 1 μg/m to 1 mg/m. The sampling method gives a time-weighted average (TWA) sample. It can be used for long-term (1 h to 24 h) or short-term (5 min to 60 min) sampling of air for formaldehyde. This part of ISO 16000 describes a sampling and analysis procedure for formaldehyde and other carbonyl compounds that involves collection from air onto cartridges coated with 2,4-dinitrophenylhydrazine (DNPH) and subsequent analysis by high performance liquid chromatography (HPLC) with detection by ultraviolet absorption [1,3]. The procedures described are written specifically for the sampling and analysis of formaldehyde in air using an adsorbent cartridge and HPLC. The method also permits the determination of other aldehydes and ketones collected from air. This part of ISO 16000 is applicable to the following carbonyl compounds: Formaldehyde Acetaldehyde Acetone Benzaldehyde Butyraldehyde Valeraldehyde 2,5-Dimethylbenzaldehyde Crotonaldehyde Isovaleraldehyde Propionaldehyde Hexanal o-Tolualdehyde p-Tolualdehyde m-Tolualdehyde note: 1) Instead of the nomenclature according to IUPAC regulations, the more common names are used in this International Standard: formaldehyde: methanal acetaldehyde: ethanal acetone: 2-propanone butyraldehyde: butanal crotonaldehyde: 2-butenal isovaleraldehyde: 3-methylbutanal propionaldehyde: propanal m -tolualdehyde: 3-methylbenzaldehyde o -tolualdehyde: 2-methylbenzaldehyde p -tolualdehyde: 4-methylbenzaldehyde valeraldehyde: pentanal

This part of ISO 6145 specifies a method for the continuous production of calibration gas mixtures, containing two or more components, from pure gases or other gas mixtures by use of commercially available multi-piston, volumetric pumps. Pumps of this type may be employed to prepare gas mixtures in which the volume fractions of the gaseous components in the complementary gas range from 0,1 % upwards; the relative expanded uncertainty of measure-ment, U, obtained by multiplying the relative combined standard uncertainty by a coverage factor k = 2 is not greater than 0,5 %. Lower concentrations may be obtained by cascading volumetric pumps, and the lowest volume fraction achievable by means of a two-pump cascade is 10. Moreover, if pre-mixed gases are used instead of pure gases, much lower concentrations can be obtained. The merits of this method are that a large quantity of the gas mixture can be prepared on a continuous basis, and that multicomponent mixtures can also be readily prepared.
