GB/T 22727.1-2008 Limits and methods of measurement of certain hazardous substances in telecommunication product Part 1: Telecommunication terminal (English Version)
1 Scope
This part specifies the limits and methods of measurement of six hazardous substances in the telecommunication terminal products, i.e., lead (Pb), mercury (Hg), cadmium (Cd), hexavalent chromium [[Cr(VI)], polybrominated biphenyls (PBB), and polybrominated diphenyl ethers (PBDE).
For the purpose of this part, the limits are applicable to the telecommunication terminal products listed in the Key management catalogue for electronic information product pollution control, while the methods of measurement are applicable to telecommunication terminal products.
