Foreword

"Gold products destructive determination of gold content" is divided into two parts. --- Part 1. electron probe micro-analysis; --- Part 2. Comprehensive measurement method. This is Part 2. This Part replaces GB/T 17364-1998 "nondestructive quantitative analysis method of gold content in gold products." This portion of the GB/T 17364-1998 main changes are as follows. --- "Non-destructive quantitative analysis method" to "Comprehensive measurement method"; --- "Reference standard" to read. "normative references"; --- Added "term and symbol" part; --- "Normative" to "informative annex"; --- Use the "accuracy" to use the "uncertainty"; --- Added "measurements" section; --- Added "original recording format" section; --- Added "Measurement Report Format" section; This section of the Appendix A, Appendix B, Appendix C, Appendix D are informative appendices.
