Foreword
This standard was drafted in accordance with GB/T 1.1-2009 given rules.
This standard is the international standard ISO 12743.2006 "Copper, lead, zinc and nickel concentrates - Determination of metal and moisture content of the sampling method" (in English
Version) non-equivalent, the main differences are as follows.
--- Of terms, definitions and provisions of the content of expression by Chinese customs have been modified;
--- Of sampling methods according to our conditions are summarized and classification;
--- Deleted extraction, sample preparation equipment and methods are not suitable for our country;
--- Increasing the sample combinations and sample preparation process;
--- Increased moisture determination method;
--- Added Appendix A "concentrate quality fluctuation test" Appendix B "test methods for checking the precision" and Appendix C "sampling system error
Poor verification method. "
This standard replaces GB/T 14260-1993 "heavy nonferrous metals flotation concentrates in bulk sampling and sample preparation General."
This standard and GB/T 14260-1993 compared to the main changes are as follows.
--- Sampling system into the clear light of international standards and quality system sampling time sampling systems;
--- Van sampling method increases the sampling methods concentrate on delivery of the car;
--- Increasing the sampling methods bagged concentrate;
--- For the determination of water balance precision equipment and the initial drying temperature has been modified;
--- Concentrate on Appendix B for checking the precision test data analysis, the deleted step to do R control charts to simplify the process.
--- Terminology, definitions and presentation of the contents of the provisions made several editorial changes.
The Standard Appendix A, Appendix B and Appendix C are normative appendix.
