5、7 1.0 APPLICATION This specification outlines the requirements for molded, resin bonded fiberglass which is used as a thermal and acoustical liner for under cab applications. Three levels of sound transmission loss are available. 1.1 Type I: No sound transmission loss requirement, this is the minimu
6、m requirement for edge coating of all grades. 1.2 Type II: Medium sound loss requirements, this is the default requirement. 1.3 Type III: High sound loss requirements. 1.4 Type IV: High sound loss requirements with foil surface and composite sound barrier. 1.5 Type V: Medium sound loss requirements
7、with foil surface, no composite sound barrier required. 1.6 For existing engineering drawings which reference this specification but do not specify a Type (I, II, III, IV, or V), Type II will be supplied. 2.0 SCOPE This specification covers the general requirements, property and performance requirem
8、ents, quality, quality, qualification, source approval, and quality control for 5 types of cab insulators. 2.1 Restricted Chemical Substances Effective January 1, 2007, all product supplied to the requirements of this specification must comply with the requirements of the CEMS B-50 specification. 3.
