ASTM D5040-90(1997)e1

Standard Test Methods for Ash Content of Adhesives

SCOPE
1.1 These test methods cover procedures used in determining the ash content of adhesives. This standard is intended as a replacement for Method 4032.1 of Federal Test Method Standard 175B, "Adhesives: Methods of Testing."
1.2 Two test methods are used:
1.2.1 Test Method A is used for a starch adhesive or other type glue, where there is no danger from the non-volatile content forming a rubbery mass when ignited.
1.2.2 Test Method B employs nitric acid to avoid the non-volatile residue being transformed into a viscous foam when ignited.
1.3 These methods are not applicable to adhesives containing decomposable salts such as zinc chloride.
1.4 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. For a specific hazard statement, see 9.2.3.
