GSO ISO 16740:2021 工作场所空气 空气颗粒物中六价铬的测定 离子色谱法和二苯卡巴肼分光光度法测量

ISO 16740:2005 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. ISO 16740:2005 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 micrograms to 10 micrograms 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. For a 1 cubic metre air sample, without sample dilution, the working range is approximately 0,01 micrograms per cubic metre to 10 micrograms per cubic metre.

GSO ISO 17091:2021 工作场所空气 氢氧化锂、氢氧化钠、氢氧化钾和氢氧化钙的测定 抑制离子色谱法测定相应阳离子的方法

ISO 17091:2013 specifies a method for the determination of the time-weighted average mass concentration of lithium hydroxide (LiOH), sodium hydroxide (NaOH), potassium hydroxide (KOH), and calcium dihydroxide [Ca(OH)2] in workplace air by collection of the particulate hydroxides on a filter and analysis of the corresponding cations using ion chromatography. For aerosol sampling, the method is applicable to the personal sampling of the inhalable fraction of airborne particles, as defined in ISO 7708, and to static (area) sampling. The method is applicable to the determination of masses of 0,005 mg to at least 2,5 mg of lithium per sample and 0,01 mg to at least 5 mg of sodium, potassium, and calcium per sample. The concentration range of particulate LiOH, NaOH, KOH, and Ca(OH)2 in air for which the measuring procedure is applicable is determined by the sampling method selected by the user. For a 1 m3 air sample, the working range is approximately 0,002 mg m−3 to at least 20 mg m−3 for all four hydroxides. For a 30 l air sample, the lower limit of the working range is approximately 0,1 mg m−3 for all four hydroxides. The procedure does not allow differentiation between the hydroxides and their corresponding salts if both are present in the air. If the cations are present alone in the form of hydroxides, the method is specific for these basic compounds. In other circumstances, the results obtained represent the highest concentration of the hydroxides that could be present in the sampled air.

ISO 17734-2:2013 gives general guidance for the sampling and analysis of airborne amines and aminoisocyanates in workplace air. It is strongly recommended that the determination of amines and aminoisocyanates is made together with the determination of isocyanates in air, using DBA as a reagent (see ISO 17734-1). The method can be used for simultaneous determinations of amines, such as 4,4'-methylenediphenyldiamine (4,4'-MDA), 2,4- and 2,6-toluenediamine (2,4- and 2,6-TDA), and 1,6-hexamethylenediamine (1,6-HDA), and compounds containing both isocyanate and amine groups, such as 4,4'-methylenediphenyl aminoisocyanate (4,4'-MAI), 2,4-, 4,2-, and 2,6-toluene aminoisocyanate (2,4-, 4,2-, and 2,6-TAI), and 1,6-hexamethylene aminoisocyanate (1,6-HAI). The method is suitable for collecting amines and aminoisocyanates in both the gas and particle phases. The instrumental detection limit for the amines is about 5 nmol/sample and for the aminoisocyanate, it is about 0,3 nmol/sample. For a 15 l air sample, this corresponds to 0,4 ng⋅m?3 for TDA and 0,03 ng⋅m?3 for TAI.

GSO ISO 16258-2:2021 工作场所空气 通过 X 射线衍射分析可吸入结晶二氧化硅 第2部分：间接分析法

ISO 16258-2:2015 specifies the analysis of RCS in samples of air collected on collection substrates (i.e. filters or foams) by X-ray diffraction, when using an analytical approach where dust from the sample collection substrate (i.e. filter or foam) is recovered, treated and deposited on another filter for analysis by the instrument. This part of ISO 16258 includes information on the instrumental parameters, sensitivity of different sampling apparatus, the use of different filters, sample treatment to remove interference and correction for absorption effects. In this part of ISO 16258, the expression respirable crystalline silica includes the most common polymorphs quartz and cristobalite. The less common polymorphs of crystalline silica, such as tridymite, are not included within the scope of this part of ISO 16258 because a standard reference material is not available. Under certain circumstances (i.e. low filter dust loads, low silica content), the analytical approach described in this method may not fulfil the expanded uncertainty requirements of EN 482[7]. Guidance for calculation of uncertainty for measurements of RCS is given in ISO 24095.

GSO ISO 20552:2021 工作场所空气 汞蒸气的测定 原子吸收光谱法或原子荧光光谱法收集和分析金汞齐的方法

ISO 20552:2007 specifies a procedure for determination of the mass concentration of mercury vapour in workplace air using a method of gold-amalgam collection with analysis by either cold vapour atomic absorption spectrometry (CVAAS) or cold vapour atomic fluorescence spectrometry (CVAFS). The procedure specifies a number of sampling methods for different applications. The procedure is suitable for making short-term measurements (e.g. 15 min) when sampling at a flow rate of between 100 ml per min and 1 000 ml per min. For assessment of long-term exposure, such as 8 h, this procedure can be used with sampling flow rate of 100 ml per min in workplaces where the concentration of mercury vapour is expected to be lower than 20 micrograms per cubic metre. If the expected concentration of mercury vapour is higher than 20 micrograms per cubic metre, it is necessary to use the procedure prescribed in ISO 17733. ISO 20552:2007 is unsuitable for making measurements of mercury vapour in air when chlorine is present in the atmosphere, e.g. in chloralkali works. Gaseous organo-mercury compounds can cause a positive interference.

ISO 15202-1:2012 specifies a method for collecting samples of airborne particulate matter for subsequent determination of metals and metalloids using inductively coupled plasma ? atomic emission spectrometry (ICP-AES). Samples obtained using the method described herein can also be subsequently analysed for elemental composition by other instrumental methods, such as atomic absorption spectrometry (AAS) or inductively coupled plasma mass spectrometry (ICP-MS). The method is not applicable to the sampling of mercury, which is present in air in the vapour phase at ambient temperatures; inorganic compounds of metals and metalloids that are permanent gases, e.g. arsine (AsH3); or inorganic compounds of metals and metalloids that are present in the vapour phase at ambient temperatures, e.g. arsenic trioxide (As2O3). The method is applicable to personal sampling of the inhalable or respirable fraction of airborne particles, as defined in ISO 7708, and to static sampling.
