A-A-59588, the commercial item description titled “Rubber, Silicone,” has just been released as a new Revision B edition. Available from Document Center Inc., the new document covers six classes of silicone rubber, in various grades. GSA (the General Services Administration) has authorized it’s use by all federal agencies.
A CID (commercial item description) is an indexed, simplified product description that describes by function or performance characteristics of available, acceptable commercial products (often referred to as “off-the-shelf”) that will satisfy the Government’s needs.
The six grades covered by A-A-59588B are:
Class 1A – Low temperature resistant.
Grades – 40, 50, 60, 70, 80
Class 1B – Low temperature resistant and low compression set at high temperature.
Grades – 40, 50, 60, 70, 80
Class 2A – High temperature resistant.
Grades – 25, 40, 50, 60, 70, 80
Class 2B – High temperature resistant and low compression set.
Grades – 25, 40, 50, 60, 70, 80
Class 3A – Low temperature, tear and flex resistant.
Grades – 30, 50, 60
Class 3B – Tear and flex resistant.
Grades – 30, 50, 60, 70, 80
The silicone rubber is usually provided in the form of sheets, strips or tape; extruded shapes or tubing; or molded shapes, as specified in the government contract or purchase order. Normally, dimensions and tolerances are indicated in the contract or purchase order as well. If not, there’s 2 tables in the specification which cover commercial tolerances that can be used.
In this new edition, where changes from the previous issue were made, the margins are marked with vertical lines. FYI: This was done as a convenience only and the Government assumes no liability whatsoever for any inaccuracies in these notations.
A-A-59588 is the document that replaced ZZ-E-765 (Rubber Fabricated Materials) when it was withdrawn in 2001. For more information on other government documents on Rubber Fabricated Materials, see our page for the Federal Supply Classification number FSC 9320.
