Foreword

This document is in accordance with the provisions of GB/T 1.1-2020 "Guidelines for Standardization Work Part 1: Structure and Drafting Rules of Standardization Documents" Drafting.

1 Scope

This document describes the terms, definitions and tests for the analysis of CCA and ACQ preservative wood and wood preservatives by X-ray fluorescence spectrometer Principles, requirements, equipment, sample preparation and determination.

This document is applicable to antiseptic wood and wood preservatives in CCA and ACQ in copper oxide, chromium trioxide, arsenic pentoxide, etc. Determination of ingredients, as well as the determination of other preservative wood and wood preservatives containing the above active ingredients.

2 Normative references

The contents of the following documents constitute the indispensable clauses of this document through normative references in the text. Among them, dated quotations Only the version corresponding to that date is applicable to this document; for undated reference documents, the latest version (including all amendments) is applicable to this document.

3 Terms and definitions

The following terms and definitions defined in GB/T 14019 and GB/T 27654 apply to this document.

4 Test principle

This method mainly uses X-ray fluorescence spectrometer to measure the K-layer electronic transition of the copper, chromium, and arsenic element electronic layers. The spectral line intensity is high small, and then determine the content of the element to be measured.
