This section 10.

The partial replacement of YS/T 568.10-2006 "zirconium oxide, hafnium and manganese contents" (formerly GB/T 2590.10-1981).

This portion of YS/T 568.10-2006 compared to the main changes are as follows.

--- Added "7.1 repeatability" clause;

--- Added "8 Quality assurance and control" clause.

The non-ferrous metal part by the National Standardization Technical Committee and centralized.

This part by the Beijing Nonferrous Metal Research Institute, China Nonferrous Metals Industry Institute of Standards Metrology and Quality is responsible for drafting.
