GB/T 14505-2010Method for chemical analysis of rocks and ores - General rules and regulations (English PDF)

Foreword

This standard replaces GB/T 14505-1993 "Methods for chemical analysis of rocks and ores General rules and regulations." This standard compared with GB/T 14505-1993, the main changes are as follows:

--- Adds elements of rock and ore chemical standard analytical methods;

--- To increase the accuracy of the test requirements of developing chemical analysis of rocks and ores standards;

--- Increased requirements for apparatus, equipment and measuring instruments shall be within the validity period of the test;

--- Increased reagents, laboratory water requirements and standard solutions should be carried out to verify alignment requirements;

--- Increased the use of the standard substance (or spike recovery), so that the test results are accurate and reliable, and traceability requirements;

--- Increasing the chemical analysis of rocks and minerals standard safety precautions for handling hazardous substances need to be to protect the environment Requirements;

--- Modified according to standard analytical sample preparation and processing;

--- Modify the content analysis results to the mass fraction w (B) represented;

--- Revised standard samples to verify test is required after confirming used. The standard proposed by the People's Republic of China Ministry of Land Resources. This standard by the Technical Committee of Standardization of Land and Resources. This standard is drafted by: National Geological Experimental Test Center. Drafting of this standard. National geology test center in Wuhan Integrated Mineral Rock Measurement Center, Institute of Geology and Mineral Resources in Zhejiang Province. The main drafters of this standard. Wangsu Ming, Yanmao Hong, Jiang Zheng deposit, 3n. This standard supersedes the previous editions as. GB/T 14505-1993. Methods for chemical analysis of rocks and ores General rules and regulations

1 Scope

GB/T 14505-2010 is the Chinese national standard on method for chemical analysis of rocks and ores - general rules and regulations, in the field of mining and minerals. The /T suffix marks it as a recommended standard: it is not compulsory by itself, but it becomes binding as soon as a contract, a tender or a customer specification calls it up - which in practice is how most foreign buyers meet it. It was issued on 10 November 2010 by the General Administration of Quality Supervision, Inspection and Quarantine of the People's Republic of China; Standardization Administration of China, and has been in force since 1 February 2011. Classification: ICS 73.080, CCS D53. This page is published from the official record of the standard held by the Chinese standards administration: the identification, the dates, the classification and the issuing body are taken from there. The clause text, the tables and the numeric limits are in the document itself, which is delivered complete in English translation.

This standard specifies the method for chemical analysis of rocks and ores General rules and regulations. This standard applies to chemical analysis of rocks and ores.
