Standard Test Method for Applied Weight Per Unit Area of Dried Adhesive Solids (Withdrawn 2005)
SCOPE
1.1 This test method covers the determination of the quantity of adhesive solids applied in a spreading or coating operation.
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.
1.3 The values stated in SI units are to be regarded as the standard. The values in parentheses are for information only.
WITHDRAWN RATIONALE
This test method covers the determination of the quantity of adhesive solids applied in a spreading or coating operation.
Formerly under the jurisdiction of Committee D14 on Adhesives, this test method was withdrawn in December 2004 in accordance with section 10.6.3.1 of the Regulations Governing ASTM Technical Committees, which requires that standards shall be updated by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.
