本技术报告就欧洲法规（即指令2011\/65\/EU（RoHS）[1]，废除2002\/95\/EU）对钢（镀铬产品除外）和铸铁的化学成分控制提供了指导，欧盟委员会授权欧盟2015\/863号指令修订2011\/65\/EU[10]和2000\/53\/EC（ELV）[2]指令附件二。这些指令要求对这些材料的镉（Cd）、六价铬（Cr（VI）、汞（Hg）、铅（Pb）、多溴联苯（PBB）、多溴二苯醚（PBDE）和四种邻苯二甲酸盐DEHP、BBP DBP和DIBP进行表征。然而，指令并未反映出这些元素\/化合物与每种相关材料的正常成分之间的对应关系。换言之，对于每一种材料，都有义务确定所列的所有化合物，而与这些控制措施的相关性无关。

The present Technical Report gives guidance regarding the chemical composition controls of steels (except chrome plated products) and cast irons in respect of the European legislation, namely Directives 2011/65/EU (RoHS) [1], repealing 2002/95/EU, the Commission Delegated Directive EU 2015/863 amending Annex II to Directive 2011/65/EU [10] and 2000/53/EC (ELV) [2]. These Directives require the characterization of these materials for Cadmium (Cd), hexavalent chromium (Cr (VI)), mercury (Hg), Lead (Pb), polybrominated biphenyls (PBB), polybrominated diphenyl ethers (PBDE) and the four phthalates DEHP, BBP DBP and DIBP. Nevertheless, the Directives do not reflect the correspondence between these elements/compounds and the normal composition of each material concerned. In other words, for every material there is an obligation to determine all the compounds listed, independently of the relevance of such controls.
