ELEMENTAL CONCENTRATION IN 20G/L TREATING SOLUTION OF PRESERVATIVE:

Oxide CCA 60% is the copper-chromium-arsenic mixture in the liquid form. When the CCA is diluted in ratio 1:20 of cold water the elemental concentrations of copper, chromium and arsenic in the treating solution of preservative complies with the data given in Table #1:

Concentration of active elements in our Oxide CCA 60% Paste (in terms of g/L) complies with the requirements of the standard SANS673: 2008, Clause 3.2.

OXIDE CONCENTRATIONS IN OXIDE CCA 60% type C:

COMPLIANCE WITH AWPA STANDARD:
In order to check compliance of Oxide CCA 60% (as per COA results) with the American Wood Protection Association (AWPA) standards, the oxides concentration as per COA (60%) are converted to a 100% oxide basis:

Our Oxide CCA 60% type C complies with the specifications stipulated by AWPA for CCA Type C in standard AWPA P23-08.

The data shown above demonstrate that Oxide CCA 60% type C sold by Hippocampus OU complies to all specifications as stipulated by the SANS (South African Bureau of Standards), AWPA (American Wood Protection Association) as well as that of the Russian manufacturer standard TU 2499-001-78576072-2009 .
The concentrations listed above may vary according to the limits stipulated in the standards’ requirements listed above, accordingly.

Chromated Copper Arsenate (CCA) is a wood preservative, a copper-chromium-arsenic mixture produced in liquid form. The mixture is diluted in accordance with the manufacturer’s instructions to give the treating solution a nominal total elemental concentration of copper, chromium and arsenate of 7,3 g/l. A 7,3 g/L total elemental concentration treating solution is equivalent to a 20 g/L solution of a preservative where the copper, chromium, and arsenic are expressed as copper sulphate pentahydrate, sodium dichromate dehydrate and arsenic pent oxide dehydrate, respectively.
CCA is the world’s most widely used wood preservative. It is manufactured to national and international standards depending on the country of intended use, including AWPA P23-10 for the USA and SANS 673 for South Africa, TU 2499-001-78576072-2009 for Russia and each manufacturer complies with these standards.
