Anotácia

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.
