YS/T 409-2012Specification for certified reference materials of non-ferrous metal product for analysis (English PDF)

Foreword

This standard follows the GB/T 15000 series of standards for the work of YS/T 409-1998 revised.

This standard replaces the YS/T 409-1998 "non-ferrous metal product samples analyzed by standard technical specifications." Compared with this standard YS/T 409-1998, the main changes are as follows.

--- Modify the terms and definitions;

--- Increasing the standard classification of non-ferrous metal samples;

--- Increasing the preparation process section component analysis using standard sample preparation procedures;

--- Modify the uniformity of the test section of a predetermined number of samples;

--- Increasing the uniformity of the test described in the order;

--- Increasing the content uniformity test methods (appendix form);

--- Increase the measurement repeatability poor homogeneity test case;

--- Increasing the uniformity of the contents of the bottle;

--- Increase the information content uniformity test results should be given;

--- Increase the stability of the test method, timing, sampling and other content;

--- Increase the stability of the test results to determine the validity and determine the content (in the form of an appendix);

--- Increased specific provisions to extend the period of validity;

--- Increased its research and development unit, the unit value of the qualification requirements and methods of valuation and valuation requirements for personnel;

--- Increase the content value statistical processing method (in the form of an appendix);

--- Modify the technical requirements of the packaging;

--- Increasing the format and content requirements of the standard sample certificate (appendix form).

This standard by the national standard sample technical committee Nonferrous Metals Technical Committee (SAC/TC118/SC3) centralized.

This standard was drafted. Technical and Economic Research Institute of Nonferrous Metals.

1 Scope

This standard specifies the composition of non-ferrous metal product samples analyzed by standard selection, processing, homogeneity testing, stability testing, analysis set Value, packaging, transportation, storage and certification requirements.

This standard applies to the development of non-ferrous metal products component analysis using standard solid and liquid samples. Development of other types of standard samples may be refer to this standard.
