This document has been declared "Stabilized" and will no longer be subjected to periodic reviews for currency. Users are responsible for verifying references and continued suitability or technical requirements. New technology may exist. This specification covers a chloroprene (CR) rubber in the form of sheet, strip, tubing, extrusions, and molded shapes. These products have been used typically for parts, such as grommets, seals, and line supports, on the firewall of aircraft or wherever flame resistance is of prime importance, but usage is not limited to such applications. Each application should be considered individually.
