Conditions characterized by a moisture content in the materials corresponding to those typically found in a well-ventilated temperate environment (temperatures generally less than 25°C and a relative humidity of the surrounding air exceeding 65% only for a few weeks per year).
Conditions characterized by a moisture content in the materials corresponding to those typically found in a tropical environment (temperatures often in excess of 25°C and a relative humidity of the surrounding air regularly exceeding 85%),or where there is occasional risk of the particleboard getting wet.
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.
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:
1 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.
Thickness, length, width and squareness tolerances shall be within the maximum tolerances stated in Tables 1 and 2 at dispatch from the producing factory.
NOTE: For certain types or uses of particleboards (see specific standards for panel types and performance standards), or in the case of dispatch in cut sizes, or where panels are further machined, special tolerances for thickness, length and width may be agreed between the user and the supplier.AS NZS 1859.1 pdf free download.
