ASTM E1793-00

Standard Practice for Preparation of Aluminum Alloy for Bonding in Foam and Beam Type Transportable Shelters

SCOPE
1.1 This practice covers the preparation of clean, uniform surfaces of aluminum alloy suitable for formation of durable adhesive bonds in "foam and beam" panels used for the manufacture of tactical shelters.  
1.2  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.
