1.1 This specification covers polyvinyl acetate or polyvinyl acetate copolymer resin emulsion adhesives suitable for use on wood, wood-based substrates, or plastic laminates. It does not cover the group of polyvinyl-based adhesives which are suitable for bonding flexible films. 1.2 The adhesives are classified at three performance levels in accordance with water-resistance as shown in Table 1 and Table 2 . See Section 5 for a description of the expected exposure conditions for each class of adhesive. See Table X1.1 for a classification of typical end products that are manufactured using adhesives at the three performance levels covered by this specification. 1.3 The following index is provided as a guide to the test methods portion of this specification: Section Tests for Physical Properties 9 Viscosity 9.1.1 Density 9.1.2 Nonvolatiles 9.1.3 pH 9.1.4 Tests for Adhesive Bond 10 Block Shear Strength, Compression 10.2 Plywood Shear Tests 10.3 1.4 The values stated in SI units are to be regarded as the standard. The values given in parenthesis are for information purposes only. 1.5 The following safety hazards caveat pertains only to the test method portion, Sections 9 and 10 , 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. 1.6 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.
