1.1 本试验方法包括通过离子色谱法定量溴化阻燃剂在塑料材料表面上的晕染。 1.2 该试验方法涉及回收未老化试样、在70°C下老化14天的试样和在70°C下老化35天的试样上含有溴化阻燃剂的塑料材料表面的沉积物。对这些沉积物进行定量分析，以获得已在表面上形成的溴化阻燃剂分数。 1.3 以国际单位制表示的数值应视为标准值。本标准不包括其他计量单位。 1.4 本标准并非旨在解决与其使用相关的所有安全问题（如有）。 本标准的用户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。 注1: 没有已知的ISO等效于本标准。 1.5 本国际标准是根据世界贸易组织技术性贸易壁垒（TBT）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》中确立的国际公认标准化原则制定的。 ====意义和用途====== 5.1 该试验方法将允许定量测定源自阻燃剂的溴，该阻燃剂在规定条件下老化后在表面上绽放。 根据所用阻燃剂的已知结构，还可以计算阻燃剂的膨胀量。 5.2 部分 14 包含一些安全建议。

1.1 This test method covers the quantification of the blooming of brominated flame retardants onto the surface of plastic materials by an ion chromatographic method. 1.2 The test method involves recovery of the deposits on the surface of plastic materials, containing brominated flame retardants, on unaged specimens, on specimens aged at 70°C for 14 days and on specimens aged at 70°C for 35 days. These deposits are quantitatively analyzed to obtain the fraction of brominated flame retardant that has bloomed onto the surface. 1.3 The values stated in SI units are to be regarded as standard. No other units of measurement are included in this standard. 1.4 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. Note 1: There is no known ISO equivalent to this standard. 1.5 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 This test method will allow the quantitative determination of the bromine originating from the flame retardant that has bloomed onto the surface after aging under specified conditions. Based on the known structure of the flame retardant used, the amount of the flame retardant that bloomed can also be calculated. 5.2 Section 14 contains some safety recommendations.
