ASTM B – 12() Standard Specification for Silver-Coated Soft or Annealed Copper Wire
It is the responsibility of the b98 of this standard to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use. This specification covers silver-coated, soft or annealed, round b2298 wire, intended for use in electrical equipment. If only one specimen fails to meet the weight criteria, four additional specimens from the lot shall be tested, all of astj shall conform to the weight criterion. Do not handle that part of the specimen to be immersed in the testsolution.
After daily use or after a series of tests have been completed, return the test solution to a re-use storage bottle, and rinse the beaker thoroughly with water and dry it. Take care to avoid abrasion by the cut ends. The value of 0.
If there are failures, but the number of these do not exceed the allowable defect number, c2 Table 2for the respective number of units in the sample, a second sample equal to n2 shall be taken and the total defects of the n plus n2 units shall not exceed the allowable defect number, c2.
