(Test Method)Standard Test Method for Determining Chloride Used in Calculating Pentachlorophenol in Solutions or Wood (Lime Ignition Method) (Withdrawn 2006)
Standard Test Method for Determining Chloride Used in Calculating Pentachlorophenol in Solutions or Wood (Lime Ignition Method) (Withdrawn 2006)
SCOPE
1.1 These procedures cover the chemical analysis by the lime ignition method of treating solutions containing pentachlorophenol and of wood treated with pentachlorophenol. The method is suitable for the determination of up to 0.05 g of pentachlorophenol in treating solutions (Section ), up to 0.05 g of pentachlorophenol in wood volumes up to 0.25 in.3 (Section 11), and up to 0.25 g of pentachlorophenol in wood volumes up to 2.0 in.3 (Section ).
1.2 This test method is not applicable to samples containing halogens other than chlorine unless appropriate correction can be made. Total halogen (excluding fluorine) is calculated as its pentachlorophenol equivalent of chloride.
1.3 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.
WITHDRAWN RATIONALE
These procedures cover the chemical analysis by the lime ignition method of treating solutions containing pentachlorophenol and of wood treated with pentachlorophenol.
Formerly under the jurisdiction of Committee D07 on Wood, this test method was withdrawn without replacement in July 2006.
