This specification covers a high strength fluorosilicone (FVMQ) elastomer that can be used to manufacture product in the form of sheet, strip, tubing, extrusions, and molded shapes. This specification should not be used for molded rings, compression seals, molded O-ring cord, and molded in place gaskets for aeronautical and aerospace applications.

This specification covers a polyalphaolefin/ester-blend fluid.

This specification covers a chloroprene (CR) rubber sponge in the form of sheet, strip, molded shapes, or other forms, as ordered.

This specification covers a standard chloroprene (CR) rubber stock in the form of molded test slabs.

This specification covers three types of rubber having good resistance to high and low temperature and hydrazine type propellants, but poor resistance to hydrocarbon oils or solvents. Hydrazines are hazardous chemicals. See Dangerous Properties of Industrial Materials; by N. Irving Sax.

The purpose of this document is to specify the O-ring sizes that are suitable for quality conformance testing (limited to hardness, tensile tests, compression set, specific gravity, and volume swell per ASTM D1414) required by AMS-7xxx series of specifications. In addition, suppliers and/or users, at their own discretion and/or according to their procurement documents, may choose to invoke this specification for procurement or other purposes for O-ring sizes that are not covered by AS568. If additional tests are specified as quality conformance tests in any AMS-7xxx specification, then that specification shall also specify the required test size for that additional test. This document does not address O-ring size for qualification testing required by AMS-7xxx series of specifications since that is already specified in the AMS-7xxx specification. This document only covers O-ring sizes required by test type. These O-ring sizes include, but are not limited to, AS568-xxx O-ring sizes.

To ensure success in design of elastomeric parts for use at low temperature, the design engineer must understand the peculiar properties of rubber materials at these temperatures.

There are no static applications of rubber. The Gaussian theory of rubber elasticity demonstrates that the elastic characteristic of rubber is due to approximately 15% internal energy and the balance, 85%, is entropy change. In other words, when an elastomer is deformed, the elastomer chain network is forced to rearrange its configuration thereby storing energy through entropy change. Thermodynamically, this means that rubber elasticity is time and temperature dependent (Reference 25).

The purpose of this report is to provide guidance on low temperature properties of rubber with the terminology, test methods, and mathematical models applicable to rubber, and to present some practical experience.
