A
This value is exclusive of silver and shall be determined by difference of “impurity total” from 100 %. “Impurity total” is defined as the sum of sulfur, silver, lead, tin,
bismuth, arsenic, antimony, iron, nickel, zinc, phosphorus, selenium, tellurium, manganese, cadmium, and oxygen present in the sample.
B
Other impurity maximums for C10100 shall be: bismuth and cadmium 0.0001 each, oxygen 0.0005, selenium 0.0003, silver 0.0025, and sulfur 0.0015.
C
Copper (including silver).
D
Oxygen in C10200 shall be 0.0010 max.
E
Cu is determined by the difference in the impurity total and 100 %.
F
Copper plus sum of named elements shall be 99.95 % min.
G
Cu + Sum of Named Elements, 99.8 % min.
H
Cu + Sum of Named Elements, 99.6 % min.
I
Cu + Sum of Named Elements, 99.5 % min.
J
When the product is for subsequent welding applications, and so specified in the contract or purchase order, zinc shall be 0.50 % max, lead 0.02 % max, phosphorus
0.02 % max, sulfur 0.02 % max, and carbon 0.05 % max.
