The included Volhard Chloride procedure, commonly called the "lime ignition" method, describes the chemical analysis of treating solutions which contain pentachlorophenol, of pentachlorophenol concentrates, and of wood treated with pentachlorophenol. The method as described is specifically suitable for the determination of the following:

• Solutions which contain less than 10 percent by weight pentachlorophenol.
• Solutions which contain more than 10 percent by weight pentachlorophenol.
• Wood volumes of less than 0.25 cubic inches [4 cm3] which contain less than 0.75 pounds per cubic foot (pcf) [12 kg/m3] pentachlorophenol.
• Wood volumes of less than 2.0 cubic inches [33 cm3] which contain less than 0.50 pcf [8.0 kg/m3] pentachlorophenol.
