Specifications

Sound Attenuation Batt Insulation complies with ASTM C 665, Type I, ASTM E 136 and the MEA 332-83-M requirements of New York City. Federal Specification HH-I-521F has been canceled and is replaced by ASTM C665. The surface burning characteristics of Sound Attenuation Batt Insulation were derived from product tests per ASTM E 84.

This standard is used solely to measure and describe properties of products in response to heat and flame under controlled laboratory conditions, and should not be used to describe or approve the fire hazard of materials under actual fire conditions. However, the results of these tests may be used as elements of a fire risk assessment that takes into account all of the factors pertinent to an assessment of the fire hazard of a particular end use. Values are reported to the nearest five rating.
