Downloaded from https://www.everyspec.com MIL-HDBK-695D 1. SCOPE 1.1 Purpose. This handbook establishes guidelines for time periods for the expected life of elastomeric products during shelf storage. The use of the expected shelf storage lives listed herein is NOT MADE MANDATORY by this handbook. The decision as to whether or not a product will have a limit placed upon the time that it may remain in storage is a function of the agency responsible for the product's ultimate use. 1.2 Scope. The handbook covers only those elastomeric products described by Government specifications and standards or by nationally recognized technical society specifications and standards.
The documents defining the items covered by this handbook were selected from the following sources: a. Acquisition Streamlining and Standardization Information System (ASSIST) (available from http://assist.daps.dla.mil/quicksearch/ or www.dodssp.daps.mil or from the Standardization Document Order Desk, 700 Robbins Avenue, Philadelphia, PA 19111-5094). b. Aerospace Materials Specifications (AMS) Index and Society of Automotive Engineers (SAE) Handbook (both available from Society of Automotive Engineers (SAE), 400 Commonwealth Drive, Warrendale, PA 15096- 0001). c.
National Aerospace Standards (NAS) (published and distributed by Aerospace Industries Association of America, Inc., 1250 I Street NW, Suite 1100, Washington DC 20005-3924). d. American Society for Testing and Materials (ASTM) Specifications (available from American Society for Testing and Materials, 100 Barr Harbor Drive, West Conshohocken, PA 19428-2959). 1.2.1 Products included. The types of elastomeric products covered by this handbook are as follows: a. Products fabricated solely from rubber. These include solid rubber, cellular rubber and hard rubber (ebonite) items. b. Composites in which the rubber is present as a discrete phase.
Examples are cables, fabric reinforced gaskets, non-aerospace hose, rubber coated fabrics, shock mounts and tires. c. Kits, accessories and outfits. The shelf life for these items should be determined by the component with the earliest expiration date. 1.2.2 Products excluded. The types of products excluded from this handbook are as follows: a. Rubber-base adhesives, coatings, sealers, and liquid rubber materials packaged in cans or tubes. b. Rubber tapes. c. Aerospace o-rings and other molded seals. Refer to SAE ARP5316 for recommended shelf lives. d. Aerospace bulk hoses and hose assemblies.
Consult SAE AS1933A for age control limits for acceptance of aerospace bulk hoses and hose assemblies. 1
