6.   NOTES

(This section contains information of a general or explanatory nature that may be helpful, but is not mandatory.)

6.1   Intended use.  The rubber procurable to this specification is intended for use where resistance to jet fuel, synthetic engine lubricants, and petroleum base hydraulic fluids are required.  Generally, materials meeting this specification are usable over   temperature range of -20°F to 500°F.   Each application, however, has to be considered individually. Instances are known where this material has been used below -20°F and also above 500°F.  Material furnished to this specification must be either black or brown in color.

6.2   Acquisition document.  Acquisition documents should specify the following:

a.        Title, number, and date of this specification. b.        Type and class (sees 1.2)

c.    Material (see 3.2)

d.    Thickness and tolerances (see 3.4)

e.    Dimensions (see 3.4)

f.     Quantity

g.    Detail drawing and additional specification, if any.

h.    Unit quantity of molded parts if other than specified in 5.1.1.3.4. i.     Applicable levels of preservation and packing (see 5.1 and 5.2).

j.     Any special marking required (see 5.3).

k.    When palletization is required (see 5.3.3)

6.3   Qualification.  With respect to products requiring qualification, awards will be made only for such products as have, prior to the time set for opening of bids, been tested and approved for inclusion in the applicable Qualified Products List whether or not such products have actually been so listed by that date. The attention of the suppliers is called to this requirement, and manufacturers are urged to arrange to have the products that they propose to offer to the Government tested for qualification in order that they may be eligible to be awarded contracts or orders for the products covered by this specification.  The activity responsible for the Qualified Products List is the Air Force Wright Laboratories, Attn: WL/MLSE, 2179 Twelfth Street, Wright-Patterson AFB, Ohio 45433-7718, and information pertaining to qualification of products may be obtained from that activity.

6.4   ARM 200.  ARM 200 can be purchased from the Society of Automotive Engineers, 400 Commonwealth Drive, Warrendale, PA 15096-0001, Phone (412) 776-4841.
