Note 1. The sample can be obtained from a sample or parts of a sampling unit, or a plurality of parts from a merger or a plurality of sampling means samples obtained.
Note 2. "Sample" (specimen) of the word, in some cases, especially for some discrete sampling materials, used instead of "sample" (sample).
3.1.4
Representative samples representativesample
One kind of quarried material samples have the same composition, and this material is considered to be completely uniform.
3.1.5
Sampling scheme samplingplan
In order to obtain the necessary understanding of the characteristic (see 3.2.15) from the final sample (see 3.2.9) to make a judgment on the goods (see 3.2.1)
