| 中文摘要: |
| 对欧盟REACH法规中与轮胎相关的多环芳烃（PAHs）含量测试的合格评定方法（标准）——IP 346和ISO 21461进行分析。IP 346和ISO 21461分别用折光指数法测试填充油（包括操作油）多环芳族化合物（PCA）萃取物含量和用核磁共振法测试成品轮胎（包括翻新轮胎）胶料中油的湾区氢含量，均是间接性测试样品PAHs含量的方法，所得结果是对样品宏观芳香性的评价，与PAHs绝对含量、苯并[a]芘（BaP）绝对含量和8种特定PAHs绝对含量无科学关联性，IP 346用于填充油和ISO 21461用于成品轮胎胶料PAHs含量合格评定缺乏合理性。采用ISO 21461对成品轮胎测试的机构少，测试成本高昂。 |
| 英文摘要: |
| In this paper，methods of determination of polycyclic aromatic hydrocarbons（PAHs） related to tire for compliance assessment（standard） in EU REACH Regulation，IP 346 and ISO 21461，were analyzed.In IP 346 method，the content of extracted polycyclic aromatic compound（PCA） in rubber extending oil（including operating oil） was measured by the refractive index method.In ISO 21461 method，the content of the bay-proton in rubber extending oil of the finished tire（including retreaded tire） was determined by nuclear magnetic resonance spectroscopy（NMR）.Both standards used indirect testing methods for determining PAHs content，and the testing results were only applicable for assessment of macroscopic aromatic characteristics and not scientifically correlated with the absolute content of PAHs，benzo[a]pyrene（BaP） and any specific type of eight appointed PAHs. Therefore，these two methods lacked solid scientific foundation.Moreover，very few testing facilities had the testing capability according to ISO 21461 and its testing cost was quite high. |
