ASTM D246-04a

Standard Test Method for Distillation of Creosote and Creosote-Coal Tar Solutions (Withdrawn 2006)

SCOPE
1.1 This test method covers a procedure for the distillation of creosote and creosote-coal tar solution. Test Methods D38 covers the sampling of wood preservatives prior to testing.  
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WITHDRAWN RATIONALE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 a procedure for the distillation of creosote and creosote-coal tar solution. Test Methods D 38 covers the sampling of wood preservatives prior to testing.
Formerly under the jurisdiction of Committee D07 on Wood, this test method was withdrawn with no replacement in July 2006.
