Standard Test Method for Amylaceous Matter in Adhesives

SIGNIFICANCE AND USE
5.1 This test method is used to determine if a melamine resin, a phenol, or a resorcinol adhesive contains any starch-like filler, the presence of which could affect water resistance or strength, or both.
SCOPE
1.1 This test method covers the determination of the presence or absence of amylaceous (starch-like) material in phenol-, resorcinol-, and melamine-resin adhesives.  
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 the user of this standard to establish appropriate safety, health, and environmental practices and determine the applicability of regulatory limitations prior to use.  
1.4 This international standard was developed in accordance with internationally recognized principles on standardization established in the Decision on Principles for the Development of International Standards, Guides and Recommendations issued by the World Trade Organization Technical Barriers to Trade (TBT) Committee.
