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 1.
This Part replaces GB/T 17363-1998 "Method of quantitative electron probe microanalysis on gold products."
This portion of the GB/T 17363-1998 main changes are as follows.
--- Added Appendix A (informative) "original record format";
--- Added Appendix B (informative) "Measurement Report Format";
--- With "accuracy" indicates the measurement error range, to use the "standard uncertainty" represents a measurement error range;
--- Scope added "component of relatively uniform gold products";
--- Increasing the scope of the articles in "determination does not apply to non-uniform composition or gold plated gold content of the article as a whole";
--- "Weight percent" to "quality score."
Appendix A of this section and Appendix B is an informative annex.

Gold products nondestructive determination of gold content
Part 1. Electron Probe Microanalysis
1 Scope
GB/T 17363 in this section specifies the method for the determination of gold content of the main elements of the article with an electron probe spectrometer.
This section applies to the determination of composition is relatively homogeneous gold products. Also applicable to the determination of thickness greater than 3μm gold or gold products
Surface gold content.
This section does not apply to non-uniform composition or determination of gold content of the article as a whole gold plating.

3 Terms and Definitions
JJF1001-1998 and the following terms and definitions apply to this section.
3.1
Surface gold content
Some products have a surface coating or cladding. Gold plating or cladding content called "surface gold content."
3.2
Simple substance
It made of a material elements called "elemental." Such as. gold, silver, copper and the like.
3.3
Quality Score
Mass of an element in the quality of the sample divided by the sample values \u200b\u200bobtained, expressed as a percentage.
4 Fundamentals
Without changing the electron probe micro-analyzer operation state conditions were measured electron excitation area measured gold articles and reference materials
Characteristic X-ray intensity emitted, and calculate the characteristic X-ray intensity ratio k related elements, then ZAF correction calculation, eligible
It was the mass fraction of gold and gold products in other major elements.
