AS/NZS 1605.4:2018
Methods for sampling and analysing timber preservatives and preservative-treated timber - Part 4: Analysis methods for determination of preservative solution concentration
Specifies analysis methods for the determination of preservative solution concentration. Analytical procedures for the determination of specific preservative components are given for oil-borne and waterborne preservatives. Calculations are provided for determining compliance with relevant standards, including the AS/NZS 1604 series and NZS 3640. This Standard is intended to be read in conjunction with the AS/NZS 1604 series, NZS 3640 or the relevant Standard to which timber is claimed to have been treated, and AS/NZS 1605.1. The preservatives incorporated in the AS/NZS 1604 series are required to be accompanied by analytical methods for their determination, which are incorporated in the AS/NZS 1605 series.
