6、根据我国电气化铁路发展的需要，结合我国具体情况参照了相应的德国标准(DIN)和日本铁路标准(JRS)部分章节的有关内容，在TB/T2809-1997《电气化铁道用接触线通用技术条件》,TB/T2810-1997《铜接触线》和TB/T2821-1997《铜合金接触线》基础上进行修订。本标准与EN50149-2001的一致性程度为非等效，主要差异如下:—按照我国国家标准对编排格式的要求进行了修订;—将国外标准的表述改为适用于我国标准的表述;—参照了JRS36512-3F-14AR3A(电车线(G合金)》中的耐软化试验有关内容;—修改了接触线的检验规则。本标准代替TB/T28

7、09-1997《电气化铁道用接触线通用技术条件》。本标准与TB/T2809-1997相比主要变化如下:—将TB/T2810-1997《铜接触线》,TB/T2821-1997《铜合金接触线》纳人本标准;—列出了铜及铜合金化学主要成分，对材料选用重新进行修订;—以附录形式增补了对接触线横向晶粒尺寸和含氧量的技术要求;—增加了接触线振动试验、疲劳试验的相应技术要求;—修改了接触线的检验规则。本标准附录A、附录B为资料性附录。本标准由中铁电气化局集团有限公司提出并归口。本标准起草单位:铁道部产品质量监督检验中心、烟台金晖铜业有限公司、江阴市电工合
