Issued by the Ministry of Industry and Information Technology of the People's Republic of China
This standard is drafted in accordance with the rules given in GB/T 1.1-2009.
This standard replaces YS/T 70-2005 "coarse copper", compared with YS/T 70-2005, the main changes are as follows.
The contents of As, Pb, Ni and Zn in the three grades Cu99.40, Cu99.00 and Cu98.50 were relaxed.
--- the original standard "each piece of coarse copper weight.200kg ~ 1200kg" to "400kg, 600kg, 800kg, 1000kg, 1200kg
Five specifications ", and increased the size requirements and appearance of the schematic;
--- increase with high gold and silver (Au ≥ 10g/t or Ag ≥ 500g/t) of the volume than the bit-like drilling method;
The size of the dies-like particle size increased by 2mm standard sieve, delete the use of magnets to remove iron and iron mixed with the operating procedures;
--- the original standard "coarse copper factory, should be accompanied by a small sample ingot" to "thick copper shipments, should promptly notify the demand side."
This standard is proposed by the National Committee for Standardization of Nonferrous Metals (SAC/TC243).
