Foreword
This standard is drafted in accordance with the rules given in GB/T 1.1-2009.
This standard replaces GB/T 4135-2002 "silver". Compared with GB/T 4135-2002, this standard has been modified as follows.
--- change the standard name to "silver ingot";
--- delete GB/T 4315-2002 in the granular silver and rod-like silver content;
--- Ic-Ag99.99 grade Cu impurity content requirements from 0.003% to 0.0025%;
--- Ic-Ag99.99 grade Te content modified to no more than 0.0008%;
--- Delete GB/T 4315-2002 Table 1 "Note 2. lead system recovery silver IC-Ag99.99 grades in the bismuth mass fraction can not be large
At 0.001% ";
--- silver ingot physical specifications to increase the appearance of the size and weight requirements and weight requirements;
--- ingot physical specifications of the ingot weight from the four specifications modified to two specifications (15kg, 30kg);
- the content of the test method has been modified and in the test method to add the silver ingot size detection equipment requirements;
--- 3.4.2 modified as. 30kg silver ingot top pit deep should not be greater than 12mm.
