Accessed by TAFE QUEENSLAND INSTITUTES on 19 Dec 2007 AS/NZS 1604.3:2004 2 PREFACE This Standard was prepared by the Joint Standards Australia/Standards New Zealand Committee TM-006, Timber Preservation and Durability, to supersede AS/NZS
13、1604.3:2002. This Standard incorporates Amendment No. 1 (July 2006). The changes required by the Amendment are indicated in the text by a marginal bar and amendment number against the clause, note, table, figure, or part thereof affected. The objective of this Standard is to specify requirements for
14、 preservative treatment of plywood products for protection against decay or insect attack. The objectives of this revision are to (a) include requirements for seasoned softwood framing to be used south of the Tropic of Capricorn in hazard class H2 exposure conditions (in Section 3); and (b) amend th
15、e requirements for tributyltin-naphthenate-based preservatives used in structural products in hazard class H3 exposure conditions. This Standard does not specify the methods of preservative treatment to be adopted to achieve the specified penetrations and retentions. Where the user is uncertain of t

29、insect or marine borer attack. This increases the range for the end application of the plywood product and renders it a more useful and reliable material for construction, building and engineering purposes. The service life of the plywood product depends on a variety of factors. These include the na
30、tural durability of the timber species, the degree of preservative treatment, the range of hazards, the quality and type of glueline, and the type of environment anticipated during the service life of the product. In addition, the severity of exposure can be reduced by alternative design. Regular in
31、spection and maintenance procedures will assist in minimizing the effects of exposure. In all conditions of use, the non-durable timber component of the plywood products can be made durable by correct preservative treatment. Service life may depend upon the plywood products having been ripped, cross
32、-cut, shaped, bored, machined or having had any such operations or processes carried out prior to preservative treatment. Where subsequent machining is unavoidable and the treatment type is an envelope, supplementary protection should be applied to the cut surface; however, this protection cannot be
33、 expected to be as effective as the original recommended treatment.

34、S C O P E A N D G E N E R A L 1.1 SCOPE This Standard sets out a specification for preservative treatment of plywood products where the maximum thickness of any veneer does not exceed 5.0 mm. It specifies the bond type, preservative penetration pattern, and the preservative retention requirements su
35、itable for each hazard class (see Table 1). This Standard does not cover grade or seasoning condition. 1.2 APPLICATION This Standard, in conjunction with AS 1604.1 and AS/NZS 1605, is intended for application throughout Australia and New Zealand. NOTES: 1 This Standard does not apply to finger-joint
36、ed material. For finger-jointed material, the specifications in AS 1604.1 apply. 2 In Queensland the Timber Utilisation and Marketing Act 1987 and in New South Wales the Timber Marketing Act 1977 require approval of a preservative treatment and registration of a brand before timber, offered for sale
37、 in either of these states, can be described as preservative-treated. Detailed information about requirements of such legislation may be obtained from the state, territory or federal forestry authorities, or trades associations. 3 Where products are to be treated to comply with the requirements of t
38、his Standard, timber treaters should select suitable timber material to ensure that the finished product can be penetrated to the depth required for each hazard class. 4 Where a timber species treatment properties are not known, trial samples placed into a normal charge/process should give indicatio
39、ns of the timbers treatability. These indications should serve as a guide for the treater. 5 The following references set down the treatment properties of some well known commercial timbers of the world: (a) BS EN 350-2 (see Clause 1.3).
