Table of Elastomer Shelf Life Recommendation: The Society of Aerospace Engineers (SAE) issued Aerospace Recommended Practice (ARP) 5316 was issued in 1998 to supercede MIL-HDBK-695C (canceled) as the aerospace industry standard. APR 5316 is often used as a guideline in determining useful shelf life of elastomers used in other industries
