1.1 This test method covers the determination of the water solubility of an organic solvent used as an auxiliary or cosolvent for pentachlorophenol or other biocides in wood preserving solutions. Conversely, the solvent solubility in the water may also be determined. Auxiliary solvents are used to either formulate high concentrations of penta or other biocides for shipment of liquid concentrate for subsequent dilution with an oil, or to boast the biocide solvency of the petroleum solution when mixed for treating.

1.2 This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use.
