1998, the Society of Aerospace Engineers (SAE) issued Aerospace
Recommended Practice (ARP) 5316. It was intended to fully
replace MIL-HDBK-695C as the industry standard for the Shelf
Life of Aerospace elastomeric seals. However, APR 5316 can
also be used as a useful guideline for the Shelf Life of many
industrial and commercial grade elastomers as well.
The information in ARP 5316, and the chart below, is intended
to be utilized by those organizations who do not already have
specific recommendations for the control of elastomeric seals.
It should be noted that the packaging of the elastomeric seals
prior to assembly into a product is an integral part of of
the controlled storage procedure. It provides a positive means
of product identity from the time of manufacture, to the time
ARP 5316 does not establish limitations for storage times
in assembled components, nor does it in any way provide a
guideline for the operating life span of a particular compound.
