Foreword
Instead of the standard YS/T 87-1995 "copper, lead anode slime of gold, silver analysis sampling and sample preparation method."
Compared with this standard YS/T 87-1995, mainly the following modifications.
--- The standard name changed to "copper, lead anode slime sampling and sample preparation methods," to expand the scope of application of the standard;
--- Increasing the sample preparation method mix;
--- Increasing the flow chart of sample preparation sample;
--- Increasing the sample water sample measured parallel alignment process;
--- Increasing the sample preparation equipment and tool requirements;
--- Increasing the amount of sample preparation requirements;
--- The inspection lot like arbitration adjustment from 30 days to 45 days;
--- Moisture measurement accuracy by a sense of balance is not more than 0.1g, adjust the scale value is not more than 0.01g;
--- Original sample volume less than 2kg, modify parts of the sample volume of not less than 70g, the inspection lot like amount of not less than 3kg;
--- The original sample size by the final revised to 0.125mm 0.098mm;
--- Modify the original sample amount, the original water sample 3.5, 3.6 component sample;
--- Will lead anode slime water bag may not exceed 20%, adjusted to 30%.
