1.1 该离子色谱测试方法描述了在混合纤维素酯（MCE）过滤器上从工作场所大气中收集的空气样品中硫酸雾的测定。 注1: 其他过滤器类型，如石英纤维、聚四氟乙烯（PTFE）和聚氯乙烯（PVC）过滤器也适用。 1.2 该测试方法的检测下限为0.001 mg/样品或0.017 毫克/米 3. 硫酸（H 2. 所以 4. )雾在60 以1L/min采样的空气L。 1.3 本试验方法受到可溶性和部分可溶性硫酸盐的干扰。其他含硫化合物可以被氧化成硫酸盐，也会产生干扰。 1.4 以国际单位制表示的数值应视为标准。本标准中不包括其他计量单位。 1.5 由于离子色谱（IC）系统的不同品牌和型号之间存在差异，因此没有提供详细的仪器操作说明。 相反，分析员应遵循所用特定仪器、分析柱和抑制器制造商提供的说明。 1.6 本标准并非旨在解决与其使用相关的所有安全问题（如有）。本标准的使用者有责任在使用前制定适当的安全、健康和环境实践，并确定监管限制的适用性。 有关具体的预防说明，请参阅第节 9 。 1.7 本国际标准是根据世界贸易组织技术性贸易壁垒委员会发布的《关于制定国际标准、指南和建议的原则的决定》中确立的国际公认的标准化原则制定的。 ===意义和用途====== 5.1 硫酸用于制造化肥、炸药、染料、其他酸、羊皮纸、胶水、铅酸电池、纺织品等。 ，以及用于金属的酸洗。 5.2 已发现该试验方法在硫酸测量方面令人满意，可与相关职业接触限值进行比较。 注2: 在一些国家，硫酸的职业接触限值（OELV）与胸部气溶胶分数有关；在这种情况下，建议使用胸部气溶胶部分的采样器（ISO 20581）。 6.

1.1 This ion chromatographic test method describes the determination of sulfuric acid mist in air samples collected from workplace atmospheres on a mixed cellulose ester (MCE) filter. Note 1: Other filter types such as quartz fiber, polytetrafluoroethylene (PTFE), and polyvinyl chloride (PVC) filters are also suitable. 1.2 The lower detection limit of this test method is 0.001 mg/sample or 0.017 mg/m 3 of sulfuric acid (H 2 SO 4 ) mist in 60 L of air sampled at 1 L/min. 1.3 This test method is subject to interference from soluble and partially soluble sulfate salts. Other sulfur-containing compounds can be oxidized to sulfate and also interfere. 1.4 The values stated in SI units are to be regarded as standard. No other units of measurement are included in this standard. 1.5 No detailed instrument operating instructions are provided because of differences among various makes and models of ion chromatography (IC) systems. Instead, the analyst shall follow the instructions provided by the manufacturer of the particular instrument, analytical column, and suppressors used. 1.6 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, health, and environmental practices and determine the applicability of regulatory limitations prior to use. For specific precautionary statements, see Section 9 . 1.7 This international standard was developed in accordance with internationally recognized principles on standardization established in the Decision on Principles for the Development of International Standards, Guides and Recommendations issued by the World Trade Organization Technical Barriers to Trade (TBT) Committee. ====== Significance And Use ====== 5.1 Sulfuric acid is used in the manufacture of fertilizer, explosives, dyestuffs, other acids, parchment paper, glue, lead acid batteries, textiles, etc., and in the pickling of metals. 5.2 This test method has been found to be satisfactory in the measurement of sulfuric acid for comparison with relevant occupational exposure limits. Note 2: In some countries the occupational exposure limit value (OELV) for sulfuric acid is related to the thoracic aerosol fraction; in such cases it is recommended to use a sampler for the thoracic aerosol fraction (ISO 20581). 6
