Asuperscript epsilon () indicates an editorial change since the last revision or reapproval.1. Scope1.1 This specification covers starch, dextrin, c

3、asein, resin base, and other liquid adhesives (excepting pressure-sensitive types)used for sealing the top flaps of fiberboard shipping cases. It includes provisions for adhesive selection based on: (1) satisfactorymachining characteristics on specific equipment, and (2) adequate adhesion under spec

15、 0.9-L (1-qt) aliquot consisting of a composite taken when possible from three or moreseparate containers chosen at random. Samples also shall be taken from containers that appear to be nonrepresentative and shallbe tested separately. Before a sample is withdrawn, mix the contents in the container t

Samples of boardsused for all bonding permanency tests shall be within a defined range of water absorptive

The specific range shall be selected by the purchaser and shall be based upon the adhesive for shipping cases used on theproduction line.6.3 Test a minimum of six board or board-facing materials samples in selecting the sample for each adhesion study.
