(Specification)Standard Specification for Adhesives for Duct Thermal Insulation
Standard Specification for Adhesives for Duct Thermal Insulation
ABSTRACT
This specification covers minimum material requirements, and safety precautions in application, for adhesives to bond thermal insulation duct liner on the interior surfaces of sheet metal air conditioning ducts; and for coating exposed edges and joints of duct liner thermal insulation to minimize erosion of insulation fibers by air movement. Adhesives shall be classified as follows: Type I; Type II; Type III; and Type IV. The following test methods shall be performed: bonding strength; bond retention after heat aging; flame spread and smoke developed; edge-burning test; storage stability; and precision and bias.
SCOPE
1.1 This specification covers minimum material requirements, and safety precautions in application, for adhesives to bond thermal insulation duct liner on the interior surfaces of sheet metal air conditioning ducts; and for coating exposed edges and joints of duct liner thermal insulation to minimize erosion of insulation fibers by air movement.
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 and health practices and determine the applicability of regulatory limitations prior to use. For specific precautionary statements, see Sections 7 and 9.
