This specification covers aspects important to the fabrication, cleaning, handling, identification, documentation, and shipping of Fluorel (fluro-elastomer) rubber parts produced for installation within the LIGO vacuum systems.
1) Removed the "applicable documents" section (was unnecessary)
2) Changed the amount of carbon black (N990) from 20 to 30 phr (parts per hundred of rubber/Fluorel)in order to achieve a durometer of Shore A 75.
3) Changes the appendix A sources for cleanroom materials to be consistent with the latest version of the LIGO Contamination Control Plan (E0900047-v9)
