1.1 本试验方法涵盖了炭黑中EU-11多环芳烃（PAH）清单的定性和定量测定。EU-11多环芳烃化合物清单见 表1 该方法包括用甲苯进行索氏提取，然后使用气相色谱和质谱（GC/MS）进行提取物分析。该方法不适用于美国。食品药品监督管理局（FDA 21 CFR 178.3297）用于间接食品接触应用的炭黑合规性。 1.2 单位- 以SI单位表示的值应被视为标准。本标准不包括其他计量单位。 1.3 本标准并不旨在解决与其使用相关的所有安全性问题（如果有）。本标准的使用者有责任在使用前建立适当的安全、健康和环境实践并确定法规限制的适用性。1.4 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》中确立的国际公认的标准化原则制定的。 ======意义和用途====== 5.1 本试验方法用于测定通过索氏提取装置用甲苯从炭黑中提取的EU-11表中多环芳烃化合物的单个浓度。

1.1 This test method covers the qualitative and quantitative determination of the EU-11 list of polycyclic aromatic hydrocarbons (PAH) on carbon black. The EU-11 list of PAH compounds is given in Table 1 . The procedure involves Soxhlet extraction with toluene followed by extract analysis using gas chromatography with mass spectrometry (GC/MS). This method is not intended to test for U.S. Food and Drug Administration (FDA 21 CFR 178.3297) compliance of carbon blacks used for indirect food contact applications. 1.2 Units— The values stated in SI units are to be regarded as the standard. No other units of measurement are included in this 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, health, and environmental practices and determine the applicability of regulatory limitations prior to use. 1.4 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 procedure is used to determine the individual concentrations of the PAH compounds in the EU-11 list extracted from carbon black by the means of a Soxhlet extraction apparatus with toluene.
