scope:

This specification defines the minimum durability requirements of all interior, luggage compartment, and climate control sound absorption/insulation applications, where various materials are combined to provide an assembly having acoustical sound absorption/barrier/insulation and/or functional features. This does not include engine (hood) compartment insulators, thermal insulators, and/or exhaust shields. In addition, ultra-high temperature parts exposed to heat from turbochargers, EGR systems and exhaust pipes are not included.
