General rules for sampling and sample preparation of heavy nonferrous metals flotation concentrates in bulk ICS 77.120.01 D42 National Standards of People's Republic of China Replacing GB/T 14260-1993 Heavy nonferrous metals flotation concentrates in bulk sampling and sample preparation General (ISO 12743.2006 (E), Copper, lead, zincandnickelconcentrates- moisturecontent, NEQ) Issued on. 2010-12-23 2011-09-01 implementation Administration of Quality Supervision, Inspection and Quarantine of People's Republic of China Standardization Administration of China released ForewordThis 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. The standard proposed by China Nonferrous Metals Industry Association. This standard by the national non-ferrous metals Standardization Technical Committee (SAC/TC243) centralized. This standard is drafted by.
