dr harry greaveskeeping standards up-to-datestandards are living documents which reflect progress in science, technology and systems. to maintain their currency, all standards are periodically reviewed, and new editions are published. between editions, amendments may be issued. standards may also be withdrawn. it is important that readers assure themselves they are using a current standard, which should include any amendments which may have been published since the standard was purchased.detailed information about joint australian/new zealand standards can be found by visiting the standards web shop at .au or standards new zealand web site at www.standards.co.nz and looking up the relevant standard in the on-line catalogue.alternatively, both organizations publish an annual printed catalogue with full details of all current standards. for more frequent listings or notification of revisions, amendments and withdrawals, standards australia and standards new zealand offer a number of update options. for information about these services, users should contact their respective national standards organization.we also welcome suggestions for improvement in our standards, and especially encourage readers to notify us immediately of any apparent inaccuracies or ambiguities. please address your comments to the chief executive of either standards australia or standards new zealand at the address shown on the back cover.this standard was issued in draft form for comment as dr 06082.as/nzs 1605.4:2006australian/new zealand standardmethods for sampling and analysing timber

standard was prepared by the joint standards australia/standards new zealand committee tm-006, timber preservation and durability, to supersede (in part), as/nzs 1605:2000, methods for sampling and analysing timber preservatives and preservative-treated timber.the objective of this standard is to set out a series of methods for sampling and analysing timber preservatives and preservative-treated timber.this revision separates the current as/nzs 1605 into a four-part series as follows: as/nzs1605methods for sampling and analysing timber preservatives and preservative-treatedtimber1605.1part 1: general requirements, sampling, and determination of sapwood and heartwood presence1605.2part 2: determination of preservative penetration by spot tests1605.3part 3: analysis methods for determination of preservative retention1605.4part 4: analysis methods for determination of preservative solution concentration(this standard)the preservatives approved for use and 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.contentspagesection 1 scope and general1.1scope . 71.2application
