AWPA A6918, Standard Method to Determine the Penetration of Copper Containing Preservatives, is employed to determine the penetration depth of copper containing preservatives into treated wood to decide whether the treated product meets acceptance levels as prescribed in treatment standards.
AWPA A7018, Standard Method to Determine the Penetration of Pentachlorophenol Using a SilverCopper Complex Known as PentaCheck. This standard is employed to determine the penetration depth of pentachlorophenol containing preservatives where the wood has been treated with pentachlorophenol dissolved in light-colored Hydrocarbon Solvent Type A or Hydrocarbon Type C
of AWPA Standard P9 into treated wood to decide whether the treated product meets acceptance levels as prescribed in treatment standards.
AWPA A7118, Standard Methods for Determining Penetration of Solvent Used with Oil-Soluble Preservatives.
This standard is provided exclusively for determining the penetration of oilsoluble organic biocides in wood where the wood has been treated with the oilsoluble organic biocide dissolved in light-colored Hydrocarbon Solvent Type A of AWPA Standard P9.
AWPA M219, Standard for the Inspection of Preservative Treated Products for Industrial Use. This Standard provides procedures for inspection at wood preserving plants of industrial products including but not limited to poles, crossarms, piling, ties, timbers, round posts and composite wood products.
