TREATMENT OF ROOF, CEILING AND TIMBER ROOF COMPONENTS WITH COPPER-CHROME-ARSENIC PRESERVATIVES FOR INDOOR ABOVE-GROUND USE - SPECIFICATION
This Malaysian Standard specifies requirements for treatment of all timber components used in roof and ceiling construction where termites and wood boring insects are common threats to structural performance of these timbers.
This standard is only applicable to timber that is used for indoor above-ground contact, protected from wetting during service. The treatment specified in this standard has been primarily designed for copper-chrome-arsenic preservative (CCA) formulations complying with MS 733. It does not cover the remedial treatment of existing timber in old buildings nor does it deal with the protection of timber against fire, weathering or staining.
CAUTION: Attention is drawn to the mandatory requirement that the CCA marketed in this country shall be registered with the Pesticides Board Malaysia under the Pesticides Act (Amendment 2004).
