Foreword

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

Drafting.

This document replaces GB/T 14019-2009 "Terminology for Wood Preservation". Compared with GB/T 14019-2009, the only changes are structural adjustments and editing.

Aside from the sexual alterations, the main technical changes are as follows.
