GB/T 2007《散装矿产品取样、制样通则》分为六个部分,本部分为GB/T 2007的第4部分。
本部分将GB/T 2007.4-1987《散装矿产品取样、制样通则　精密度校核试验方法》和
GB/T 2007.5-1987《散装矿产品取样、制样通则　取样系统误差校核试验方法》合并，并做编辑性修改，代替ＧGB/T 2007.4-1987和GB/T 2007.5-1987。
本部分规定了偏差、精密度校核的术语和试验方法。
本部分适用于按GB/T 2007.1和GB/T 2007.2所列取样、制样方法精密度的校核，以及对需校核的取样方法、取样装置进行偏差校核试验，也可用于制样方法、缩分设备偏差的校核。

Scope

This section specifies the terms and test methods for deviation and precision calibration. 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 deviation checking test for the sampling methods and sampling devices that need to be checked, and can also be used for sample preparation methods , Checking the deviation of the shrinkage equipment.
