WATER SOLUBLE TYPE WOOD PRESERVATIVES

PART II COPPER-CHROME-ARSENIC (CCA ) WOOD PRESERVATIVE

0.1 This Indian Standard ( Part II ) was adoptrtl by tire lntlian Standards Institution on 30 November l(I81, nficr tlrf, clr~ft firr:lliz~,tl t)y ~II(: Timber Sectional Committee had been apl)roveti by the (‘:I\ 11 l,~r+n~~-rrrr~ Division Council.

0.2 With the rapid industrial development of the country, cor~pletl xvitlr increased construction Activity alround, tlrc demand f?x tinlbcr 1’0 r construction purposes has gt,eatly increased. In clew of the 1111 1tctt1 availability of naturally due able species, such :IS teak ( ~-P~//u/u ~s~,.~i~iG ) and sal (Shorea robusta ), it is imperative that supplies 01' durable trrrlt)c~r-s are augmented by selected timbers of lesser tlur-ability whrch, when suitably treated, would give increased life under service c olltlil ions. Preservative treatment of timber, therefor-c, forms a VCI’~ iurpor~r;Brrt ~);LT t of the national effort to conserve the nraterial resources of the country, and to achieve their most economic utilization.

0.3 IS : 401-1982* covers types of preservative, methods of treatment, and the type and choice of treatment for different species of tirnbclr for :I number of uses. The standard also lists various oil type’, organic sol\*ent type, and water-soluble ( leachable ) and water-soluble (fix&j type preservatives. The efficiency of preservative treatment depcntls, besides the proper choice of preservative and the tr-catrnent process, on the quality of the preservative to ensure required absor-ption and penerration of the preservation. This standard has been formulated to lay down requirements of copper-chrome-arsenic (CGA) - a water-soluble (fixed) type preservative.

0.4 In the formulation of this standard due weightage has been given to international co-ordination among the standards and practices prevailing in different countries in addition to relating it to the practices in the field in this country.

3.3 In case of dry powder form, a true representative sample of preserva- tive not less than 10 percent of the contents shall be taken for analysis.

3.4 At least 1 kg of the preservative shall be dissolved to obtain 15 percent solution of the preservative.

3.5 A small amount of the 15 percent solution may be drawn and diluted exactly to 5 percent for chemical analysis.

4. TESTING
