1.1 This specification covers casein and other protein-blend adhesives for use adhering wood to wood. The adhesive type covered by this specification is a dry powder or granular product comprising a mixture of casein, or casein and other protein source, with the necessary dry chemicals to effect solution when the mixture is added to water. Note 1: Although the term casein adhesive is used throughout this
specification, historically, the adhesive subclass described in
1.1 has been known as casein
glue. See Terminology D907,
1.2 Limitations—Cooked casein adhesives are
not covered by this specification.
1.3 The values stated in inch-pound units are to be regarded as standard. The values given in parentheses are mathematical conversions to SI units that are provided for information only and are not considered standard. 1.4 The following safety hazards caveat pertains only to the test method portion, Sections 8 through 13, of this specification: 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. 1.5 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. |
