GB/T 27680-2011 Copper,lead,zinc and nickel concentrates—Experimental methods for checking the bias of sampling
Abstract
This standard specifies the experimental methods for checking the sampling errors of copper, lead, zinc, and nickel concentrates. The sampling method follows ISO 12743. The methods specified in this standard can also be used to check whether there are errors in sample processing and to detect any significant differences that may exist in the analysis of samples exchanged between different locations (such as loading and unloading points) and batch samples.
