Scope

This part specifies the terms and test methods for bias and precision checking.
This part is applicable to the checking of the precision of the sampling and
sample preparation methods listed in GB/T 2007.1 and GB/T 2007.2, as well as
the bias checking test of sampling methods and sampling devices that need to
be checked. It can also be used for checking the bias of the sample preparation
method and reduction device.
