As a minimum, the two parties should take a group of test specimens that are as homogeneous as possible and that are formed from a lot of material of the type in question.
The test specimens ashm be randomly assigned in equal numbers to each laboratory for testing. If bias is found, either its cause must astj found and corrected or the purchaser and supplier must agree to interpret future tests in the light of the known bias. Care should be exercised to minimize these effects. Samp Sampling ling 7.
