Abstract

This specification covers the composition and the physical properties of spray-applied mineral fiber thermal and sound absorbing insulation. These mineral fibers shall be pneumatically conveyed to a spray nozzle where they are mixed with water. These mineral fibers shall have a binder either pre-mixed with the fibers or added at the spray nozzle with the water. The basic material shall be fibers made form mineral substances such as rock, slag or glass processed from the molten state into a fibrous form. All self-supporting applications of the insulation shall have a minimum adhesive/cohesive strength of five times the weight of the material under the testing plate when tested. The insulation shall not spall, crack, or delaminate when the substrate is deflected. The insulation shall have a maximum flame spread index of 25 and a maximum smoke developed of 50 when tested. The insulation shall have a weight loss not greater than 5 %, nor shall there be a flaming ignition when tested. When tested, the insulation shall have growth no greater than that observed on the white birch tongue depressor comparative material. The spray-applied mineral fiber shall show no greater corrosion than the comparative plate in contact with the sterile cotton for the particular metal substrate to which classification is desired. A detectable odor of a strong objectionable nature recorded by more than two of the five panel members shall constitute rejection of the material when tested. Density and thickness of each sample tested shall be determined in accordance with test methods E 605. The adhesive/cohesive strength, thermal resistance, effects of substrate deflection, water vapor sorption, surface burning characteristics, smoldering combustion, fungi resistance, particular metal substrate corrosion, sound absorption, odor emission, and air errosion characteristics shall be tested to meet the requirements prescribed.
