Standard Practice for Adhesive Bonding of Aluminum Facings in Foam and Beam Type Shelters

SIGNIFICANCE AND USE
The formation of reproducible, durable adhesive bonds in structural units requires great care in the performance of the steps in the bonding process. Experience has shown that adhesive bonding carried out in accordance with this practice produces reproducible adhesive bonds. This practice is applicable to both the Type 1, 71°C (160°F), and Type 2, 93°C (200°F), elevated humidity service type of foam and beam shelter.
SCOPE
1.1 This practice covers the materials, processes, and quality controls to be used in the manufacture of adhesive-bonded, aluminum-faced, foam core sandwich panels for tactical shelters.
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 and health practices and determine the applicability of regulatory limitations prior to use.
