欧盟玩具安全新指令化学要求及测试方法综述

2013年开始实施的欧盟玩具安全指令对化学物质的检测要求更加严格,限制迁移元素从8种增加到包含三价铬、六价铬和有机锡的19种,增加了对N-亚硝胺类物质的迁移量和致敏性芳香剂的限制;限量降低,铅、镉、六价格、有机锡限量分别只有3.4,0.5,0.005,0.2 mg/kg,传统玩具检测使用的ICP-OES和GC-MS已无法满足六价铬、有机锡、亚硝胺、芳香剂的检测要求。该文简述了指令的化学相关要求以及相应的检测方法,重点介绍了六价铬和有机锡检测方法的技术进展和技术难点。

Review on Chemical Requirements and Related Testing Methods of the New EU Toy Safety Directive

The EU Toy Safety Directive which came into force in 2013 has substaintially increased requirements on chemical substances.Restricted migration elements have been increased from 8 to 19 elements,which include trivalent chromium,hexavalent chromium and organotin.Restricted migration amount of N-nitrosamines and restriction of allergenic fragrances have been added.The limited amounts of lead,cadmium,hexavalent chromium,organotin have been decreased to 3.4,0.5,0.005,0.2 mg/kg respectively,and traditional toy testing methods such as inductively coupled plasma-optical emission spectrometry and gas chromatography-mass spectrometry cannot satisfy the testing requirements of hexavalent chromium,organotin,N nitrosamines and fragrances.This paper has briefly described the chemical requirements of TSD and corresponding testing methods,highlighted the technical progress and difficulties of testing methods of hexavalent chromium and organotin.
