Foreword

GB/T 17414 "Method for chemical analysis of beryllium ores" There are two parts. --- Part 1. Determination of the amount of beryllium Aili Luo cyanine R spectrophotometry; --- Part 2. Determination of beryllium by catalytic polarography. This section GB/T Part of 117,414. This Part replaces GB/T 17414.1-1998 "Determination of beryllium ores chemical analysis of beryllium Aili Luo cyanine R spectrophotometric amount." This section compared with the GB/T 17414.1-1998, the main changes are as follows. --- Modify this part of the English name; --- Text format has been modified; --- Formula for calculating the mass fraction represented by the symbol w instead of ω (%); --- Increased alert, warnings; --- Increased provision sample; --- Increased waste disposal provisions. Appendix A of this section is an informative annex. This section presents the People's Republic of China Ministry of Land Resources. This part of the National Standardization Technical Committee under the jurisdiction of Land and Resources. This section is responsible for drafting. National geology test center. This section is drafted. Liaoning Provincial Institute of Geology. The main drafters of this section. Chen Haiying, Wei Zhanwen. This part of the standard replaces the previous editions are. --- GB/T 17414.1-1998. Methods for chemical analysis of beryllium ores Part 1. Determination of the amount of beryllium Aili Luo Jing R spectrophotometry Warning. Use of this standard shall have a person experiences regular laboratory work. This standard does not point out all possible security issues. Users have the responsibility to take appropriate safety and health practices and to ensure compliance with the conditions relevant national regulations.
