协调标准（HD21和HD22）在2014年1月份需要换版为EN50525。 届时，HD21和HD22标准将作废，所涉及的所有PVC和橡胶线VDE证书将必须在此期限内完成EN50525标准更新。
站内似乎还没有说明新旧标准的差异，新标准也还没有发布。现提供以下信息，供各位参考：

举例： 以H03VV-F为例，需要进行的额外测试有：
cold impact at -5C( 旧标准为-15C)
增加non-compatibity test(旧标准没有此要求， 只有compatibity test）
bending test
voltage test （2000V） after bending test（旧标准在bending test后没有voltage test 的要求）
虽然新标准尚未发布，为避免项目塞车，现在即可向VDE提出申请。
