Scope

This Part of GB/T 39560 refers to the sample as the object to be processed and measured. The
nature of the sample and the manner in which it is acquired is defined by the entity carrying out
the tests.
It is noted that the selection of the sample may affect the interpretation of the test results.
While this standard provides guidance on the disassembly procedure employed for obtaining a
sample, it does not determine or specify:
• the level of the disassembly procedure required for obtaining a sample;
• the definition of a “unit” or “homogenous material” as the sample;
• conformity assessment procedures.
NOTE: Further guidance on assessment procedures of the conformity may be found in GB/Z 30374-
2013[2].
