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, except for
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):

(DDAC), dodecylbenzyldimethylammonium chloride (BAC), cyproconazole, tebuconazole, propiconazole, hexaconazole, triazole, prothioconazole, benzene
Containing etherfenoconazole, tetrafluroconazole, bis-(N-cyclohexyl)diazene dioxide (HDO), IPBC, DCOI, OIT, CMIT, MIT and boron
Quantitative measurement method and method for determining the penetration of anticorrosive wood:
This document is applicable to the determination of active ingredients in water-borne preservatives and preservative wood:
