GB/T 23229-2023Methods for analysis of waterborne wood preservatives (English PDF)

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 23229-2009 "Analysis Method for Waterborne Wood Preservatives". Compared with GB/T 23229-2009, in addition to structural adjustments and editorial changes, the main technical changes are as follows:

a) Atomic absorption spectrometry for the determination of chromium and arsenic content in preservatives containing chromium and arsenic and in preservative wood has been added (see 4.2);

b) Changed the analysis method for the determination of boron content in boron-containing preservatives and preservative wood (see 5.2, 2009 version of 5.2);

c) Added the analysis method of quaternary ammonium salts in preservative wood---two-phase titration method (see Chapter 8);

d) Added analytical methods for cyproconazole, hexaconazole, triazole, prothioconazole, difenoconazole, tetrafluroconazole, etc. (see Chapter 9, Chapter 10);

e) The analytical methods of tebuconazole and propiconazole have been changed (see Chapter 10, Chapter 8 and 9 of the 2009 edition);

f) Added 4,5-dichloro-N-n-octyl-4-isothiazolin-3-one (DCOI), N-octyl-4-isothiazolin-3-one (OIT), 5- Chloro-2-methyl Analysis methods for methyl 4-isothiazolin-3-one (CMIT), 2-methyl 4-isothiazolin-3-one (MIT), etc. (see Chapter 11 and Chapter 12);

g) Added the analytical method for iodopropynylbutylcarbamate (IPBC) (see Chapter 13).
