AS NZS 1859.1:2017 pdf free.Reconstituted wood-based panels- Specifications Part 1: Particleboard.
4.3 Particleboard
Panel material manufactured under pressure and heat from particles of wood (wood flakes, strands, chips, shavings, sawdust, and similar) and/or lignocellulosic material in particle form (flax shives, hemp hurds, bagasse fragments, rice hulls, wheat straw and similar) with the addition of an adhesive.
Wood-based particleboard may be manufactured from virgin, reclaimed or recycled fibre or combinations of each.
4.4 Recycled and reclaimed wood
Recycled materials are defined in AS 4707. Within the definition for Recycled material’,
Item (a) refers to reclaimed fibre and Item (b) refers to recycled fibre.
5 CLASSIFICATION
Particleboard is classified as follows:
(a) Standard particleboard (STD) is intended for use in dry conditions, for example, for interior fitments (including furniture) in dry areas.
(b) Moisture resistant particleboard (MR) is intended for use in humid, interior conditions, for example, for interior fitments (including furniture) in humid areas such as occur in tropical climates and in kitchens, laundries and bathrooms, where occasional wetting may occur.
NOTES:
I MR particleboard should not be used where persistent wetting is likely. If particleboard is left in continuously wet conditions, degradation will occur through adhesive failure and/or fungal attack.
2 Exterior use should be strictly in accordance with the manufacturer’s recommendations, instructions and guidelines.
6 RFQUIREMENTS AT DISPATCH
6.1 General
Particleboard shall comply with the general requirements listed in Tables I and 2 when
dispatched from the producing factory.
Some supplementary properties and their appropriate test methods are given in Clause 8.
The 5-percentile values, based on the mean values for individual panels and calculated in accordance with AS/NZS 4266.1 (as referenced in Clause 9). shall be equal to or greater than the lower specification limits in Tables 3 and 4.
The requirements in Tables 3 and 4 are lower specification values for modulus of elasticity (MOE) based on mean values. A 5-percentile calculation is not required for MOE.
7.3 Upper specification limits
The requirements in Tables 3 and 4 arc the upper specification limits for the following properties:
(a) Thickness swelling.
(b) Thickness swelling after cyclic test.
The 95-percentile values, based on the mean values for individual panels and calculated in accordance with AS/NZS 4266.1 (as referenced in Clause 9), shall be equal to or less than the upper specification limits in Tables 3 and 4.AS NZS 1859.1 pdf download.
