ASTM E1555-20

Standard Specification for Structural Paste Adhesive for Sandwich Panel Repair

ABSTRACT
This specification defines those characteristics that are required of adhesives to be used in the repair of sandwich panels for durable, rigid wall, relocatable structures. It covers two-part epoxy adhesive suitable for bonding aluminum alloy facings to nonmetallic core and core to core in the repair of durable rigid wall, relocatable structures. The adhesive shall be suitable for forming bonds that will withstand exposure to a certain temperature range and high relative humidity and will also withstand the combinations of stress, temperature, and relative humidity that are expected to be encountered in service. The adhesive shall also be suitable for the bonding of panel inserts and edge attachments. The adhesive physical characteristics such as adhesive life, curing, mix ratio, storage life, and mechanical properties shall be observed in order to determine its working characteristics. The following tests shall be conducted to determine certain mechanical properties: tensile lap shear test, flatwise tension test, climbing drum peel test, and durability test.
SIGNIFICANCE AND USE
6.1 Adhesives used in the repair of sandwich panels for durable, rigidwall, relocatable structures must have a combination of mechanical property levels and environmental resistance that will ensure long-term durability of the adhesive bonds when exposed to severe climatic exposures. In addition, these adhesives must have processability characteristics that permit their use in a variety of repair scenarios and environments.  
6.2 This specification defines those characteristics that are required of adhesives to be used in the repair of sandwich panels for durable, rigidwall, relocatable structures.
SCOPE
1.1 This specification defines those characteristics that are required of adhesives to be used in the repair of sandwich panels for durable, rigidwall, relocatable structures.  
1.1.1 This specification covers two-part epoxy adhesive suitable for bonding aluminum alloy facings to nonmetallic core, core to core, and core to perimeter aluminum extrusion frame in the repair of durable rigidwall relocatable structures. The adhesive shall be suitable for forming bonds that will withstand exposure to temperatures from −54 °C to 93 °C (−65 °F to 199 °F) and high relative humidity and will also withstand the combinations of stress, temperature, and relative humidity that are expected to be encountered in service. The adhesive shall also be suitable for the bonding of panel inserts and edge attachments.  
1.2 The values stated in SI units are to be regarded as 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 The following safety hazards caveat pertains only to the test methods described in 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.  
1.4 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.
