scope:

This specification defines the minimum durability requirements of all thermal, foam gasket and sound absorption applications, where various materials are combined to provide an assembly having thermal and/or acoustical (sound absorption/barrier) and/or functional features. This includes interior passenger, luggage compartment, engine compartment and underbody thermal and/or acoustical (sound absorbing/barrier/ insulation) parts. This document also includes high temperature applications such as exhaust shields. In addition, ultra high temperature parts exposed to heat from turbochargers, EGR systems and exhaust pipes are also included. Adhesive backed products must meet WSSM11P62- A.
