Standard Test Method for Moisture and Creosote-Type Preservative in Wood (Withdrawn 2006)

SCOPE
1.1 This test method covers the determination of the moisture content in wood and is an alternative procedure for the oven drying method given in Sections 124 to 127 of Methods D143. Its use is required when the wood contains volatile oils or oil preservative. The test method also covers the determination of the quantity of creosote or creosote-base preservative in treated wood.  
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.
WITHDRAWN RATIONALE
This test method covers the determination of the moisture content in wood and is an alternative procedure for the oven drying method given in Sections 124 to 127 of Methods D 143. Its use is required when the wood contains volatile oils or oil preservative. The test method also covers the determination of the quantity of creosote or creosote-base preservative in treated wood.
Formerly under the jurisdiction of Committee D07 on Wood, this test method was withdrawn without replacement in July 2006.
