This document specifies a method for the determination of the apparent hardness of vulcanized- or thermoplastic-rubber
1.1 This test method describes a type of composite foam hardness measurement device known as durometer: Type CF. The procedure for determining indentation hardness of substances comprised of two or more elastomeric materials, one of which is a foam or foam like material. These are classified...
This specification covers a silicone (MQ/VMQ) 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, O-ring cord, and molded in place gaskets for aeronautical...
This specification establishes the requirements for synthetic rubber materials for gaskets of 50 durometer hardness (maximum).
This specification covers a 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, O-ring cord, and molded in place gaskets for...
4.1 The International Hardness test is based on measurement of the penetration of a rigid ball into the rubber specimen under specified conditions. The measured penetration is converted into IRHD, the scale of degrees being so chosen that 0 represents a material having an elastic modulus of zero,...
This document specifies a method for determining the indentation hardness (Shore hardness) of vulcanized or thermoplastic rubber using durometers with the following scales: - the A scale for rubbers in the normal-hardness range; - the D scale for rubbers in the high-hardness range; - the AO...
1.1 This test method covers quantitative procedures for the evaluation of the compatibility of automotive engine oils with several reference elastomers typical of those used in the sealing materials in contact with these oils. Compatibility is evaluated by determining the changes in volume,...
The materials defined by these specifications are thermoplastic elastomers of nominal instantaneous Durometer 'A' hardnesses ranging from 60 to 89 having good long term resistance to heat and engine coolant at temperatures up to 125 °C. The harder materials also have moderate resistance to...
