7. Procedure
7.1 Sampling:
7.1.1 Different parts of a blister copper form may vary in composition. A sample, therefore, must be taken with care to be
representative of that form. To obtain a sample representative of a lot of the product, a number of test pieces should be sampled
individually. The sample tak
