ASTM D1950-86(1995)e1

Standard Test Method for Acetone Tolerance of Heat-Bodied Drying Oils (Withdrawn 2003)

SCOPE
1.1 This test method covers the determination of the acetone tolerance of heat-bodied drying oils when no nonfatty material is present.  
1.2 The values stated in SI units are to be regarded as the standard. The values given in parentheses are for information only.
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 whoever uses this standard to consult and establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use. Specific hazard statements are given in Section 6.
WITHDRAWN RATIONALE
This test method covers the determination of the acetone tolerance of heat-bodied drying oils when no nonfatty material is present.
Formerly under the jurisdiction of Committee D01 on Paint and Related Coatings, Materials, and Applications, this test method was withdrawn in December 2003 in accordance with section 10.6.3.1 of the Regulations Governing ASTM Technical Committees, which requires that standards shall be updated by the end of the eighth year since the last approval date.
