5.1 This specification is intended to provide information on the properties of adhesives, and the test methods required to evaluate adhesives to be used in the production bonding of aluminum alloys to foam core materials for the manufacture of tactical shelters.AbstractThis specification covers two-part adhesives for bonding aluminum alloy facing to foam core, inserts, edge attachments, and other components of a Type II foam cored sandwich panels. The adhesive should be suitable for forming bonds that can withstand long-term exposure at specified temperatures, and different combinations of stress, temperature, and humidity expected to be encountered in service. The adhesive may be used for new production or depot maintenance. The adhesive shall be a two-part thermosetting epoxy paste containing no asbestos and, when tested, shall meet the following physical and mechanical property requirements: curing time, temperature, and pressure; mix ratio; storage life; adhesive life; room-, low-, and high-temperature shear; hot humidity exposure shear; and room-temperature salt spray exposure shear.1.1 This specification covers two-part adhesives for bonding foam core sandwich panels. The adhesive may be used for new production or depot maintenance. The adhesive should be suitable for forming bonds that can withstand long-term exposure to temperatures from −55 °C  to 93 °C  (−67 °F to 200 °F) and also withstand combinations of stress, temperature, and humidity expected to be encountered in service. The adhesives shall be used for bonding aluminum alloy facing to foam core, inserts, internal aluminum framing members, and other components of a foam cored sandwich panel.1.2 The values stated in SI units are to be regarded as the standard where only SI units are given or where SI units are given first followed by inch-pound units; where inch-pound units are given first followed by SI units, the inch-pound units are to be regarded as the standard.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, health, and environmental practices and determine the applicability of regulatory limitations prior to use.1.4 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.

3.1 The failure of wood-based materials with impact loads is sometimes an important criteria in design considerations. In addition, some effects on the mechanical properties of wood, such as decay, are best evaluated by measuring its toughness. This test method serves to evaluate the toughness of structural panel products while Methods D143 can be used to measure the toughness of solid clear wood specimens.1.1 This test method for toughness of wood structural panels covers the determination of energy necessary to cause failure by impact loading of a beam specimen which is simply supported and loaded at midspan. Wood structural panels in use include plywood, oriented strand board, and composites of veneer and of wood-based layers.1.2 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.1.3 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, health, and environmental practices and determine the applicability of regulatory limitations prior to use.1.4 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.

4.1 This test method determines the cleavage force required to peel stiff facings from the core of sandwich panels, and is used to determine how well the facing is bonded to the core. Test Method D1781 only works well with flexible facings. As a guideline, the cleavage test method would work better on sandwich panels that have facings with a bending stiffness (EI) of greater than approximately 27.3 lb-in2/inch width (3.09 kN·mm 2/mm width). This converts to approximately 0.032 in. (0.81 mm) 6061 T6 aluminum alloy, 0.023 in. (0.57 mm) steel, and 0.046 in. (1.18 mm) fiberglass facings.1.1 This test method covers the determination of the cleavage force to peel stiff facings from sandwich panels.1.2 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.1.3 This standard does not purport to address all of the safety concerns, if any, associated with its use.
