Methods for sampling and analysing timber preservatives and preservative-treated timber - Part 3: Analysis methods for determination of preservative retention
Specifies analysis methods for determining preservative retention in preservative-treated wood products. The calculations necessary for determining compliance with the requirements specified in the AS/NZS 1604 series and NZS 3640 are outlined. The objective of this revision is to add analytical procedures. This standard is intended to be read in conjunction with AS/NZS 1605.1 and the AS/NZS 1604 series, NZS 3640 or the relevant Standard to which timber is claimed to have been treated. 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.
