EU regulation power cord detection operation instruction
2011-05-25 20:28:03
 

1. Objective:
To make EU regulations, China CCC Power cord are based on wire tests to follow, especially the development of this standard.
2. Application:
Our application follows the EU regulations, the national standard wire: a. H03VVH2-F (RVV 300/300V) b. H03VV-F (RVV300/300V) and A03VV-F c. H05VVH2-F (RVV 300/500V) d. H05VV -F (RVV 300/500V)
e. H03VVH2H8-F f. H03VVH8-F g. H05VVH2H8-F h. H05VVH8-F
i. RVB 300/300V
3. Definitions:
EU regulation, the national standard wire: refers to VDE, NF, IMQ, DEMK, EMKO, FIMKO, SEMKO, OVE, KEMA, CEBEC, SEV, and BS, SAA, BR, GB standard cable, because most of the above criteria is based on the content of IEC standards development.
4. Operation:
      Based on the items listed in the table on the wire inspection, sampling and testing frequency, see the "test project management approach" in terms of 3.3.1:
