ASTM C1668-10

Standard Specification for Externally Applied Reflective Insulation Systems on Rigid Duct in Heating, Ventilation, and Air Conditioning (HVAC) Systems

ABSTRACT
This specification establishes the physical and performance requirements, and the corresponding test methods, for the evaluation of reflective insulation systems that are applied externally to rigid ducts in heating, ventilation, and air conditioning (HVAC) systems operating at specified temperatures. The products covered here are classified into five types according to the substrate material used, namely: Type A, product with polyethylene foam substrate; Type B, product with polyethylene bubble pack substrate; Type C, product with fiberglass substrate; Type D, product with polyester fiber substrate; and Type E, product with kraft paper substrate. Properly sampled specimens shall undergo test procedure to examine their conformance with the following requirements: emittance, water vapor permeance, surface burning characteristics, aging resistance, adhesive performance (bleeding and delamination), pliability, fungi resistance, thermal resistance, and hot-surface performance.
SCOPE
1.1 This specification covers the requirements and physical properties of reflective insulation systems applied externally to Rigid Heating, Ventilation, and Air Conditioning (HVAC) duct systems operating at or below 250ºF (121.1 °C). These insulation systems consist of one or more low-emittance surfaces, such as metallic foil or metallic deposits, mounted on substrates to produce reflective air spaces. Reflective insulation systems derive their thermal performance from surfaces with an emittance of no greater than 0.1 facing enclosed air spaces.
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.
