This specification covers the general requirements for the 315/70R22.5 154/150L radial truck standard reference tire. Provided in this specification is a 22.5 rim diameter code standard truck tire design and construction, standard dimensions and standard condition of storage. This specified tire is...
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,...
This method is intended to define the continuous upper temperature limit (CUTL) of thermoplastic elastomers and thermoset rubber with durometer hardness <=90 Shore A, to oxidation or other degradation when exposed solely to hot air for an extended period of time.
1.1 This test method covers Type A Durometer hardness of thermoplastic pavement marking material at elevated temperatures. 1.2 This test method is similar to Test Method D2240 for hardness with special attention given to keeping the temperature of the test sample and instrument constant....
1.1 This specification covers lubricating greases suitable for the periodic relubrication of chassis systems and wheel bearings of passenger cars, trucks, and other vehicles. 1.2 This specification defines the requirements used to describe the properties and performance characteristics of chassis...
4.1 Poly(vinyl chloride) compositions degrade by discoloration on prolonged exposure to heat. The degree of discoloration is related to the condition of exposure, such as length of period and temperature. When the conditions of exposure are fixed and controlled, then the relative resistance to...
This specification covers a fluorosilicone (FVMQ) rubber in the form of sheet, strip, tubing, extrusions, and molded shapes. This specification is not to be used for the manufacture of O-rings, molded O-ring cord, or molded in place seals or gaskets for aerospace applications.
1.1 This test method covers twelve types of rubber hardness measurement devices known as durometers: Types A, B, C, D, DO, E, M, O, OO, OOO, OOO-S, and R. The procedure for determining indentation hardness of substances classified as thermoplastic elastomers, vulcanized (thermoset) rubber,...
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,...
8.1 This specification describes types (based on resistance to tearing and compression set), grades (based on durometer hardness), class (based on flame propagation requirements), and surfaces (based on surface characteristics) of products as listed in Section 4 for various applications. It...
This specification covers a self-extinguishing, pigmentable silicone (MQ/VMQ/PVMQ) elastomer that can be used to manufacture product in the form of molded, extruded, and/or calendared, sheets, strips, and shapes.
4.1 The results obtained by this test method are simply a measure of the indentation into the sealant material of the indentor under load; they are not generally considered a measure of abrasion or wear resistance of the sealant.
1.1 This test method evaluates the compatibility of lubricating greases and fluids with coupons cut from standard elastomer sheets (Practice D3182). Compatibility is evaluated by determining the changes in volume and Durometer A hardness that occur when elastomer coupons are totally immersed...
The materials defined by these specifications are colored and U.V. stabilized thermoplastic elastomers based on Styrene block copolymers (TES) for interior use of nominal instantaneous Durometer A hardnesses ranging from 45 to 90 having good long term resistance to heat at temperatures up to...
The materials defined by these specifications are colored and U.V. stabilized thermoplastic elastomers (TEO) for interior use of nominal instantaneous Durometer. A hardnesses ranging from 60 to 83 having good long term resistance to heat at temperatures up to 125 °C. Being thermoplastic, the...
Form. This specification covers a fluorosilicone (FVMQ) rubber in the form of molded rings, compression seals, O-ring cord, and molded-in-place gaskets and rubber sheets, strips, molded parts and extruded shapes for aeronautical and aerospace applications. This material is not suitable for use in...
The materials defined by these specifications are flexible polyvinyl chloride compounds.
These specifications define the requirements for thermoplastic elastomers with a durometer hardness less than 95, Type A. These materials may include but are not limited to EPDM-modified thermoplastic elastomeric olefinic and their vulcanizates (TEO, TPV) and styrenic block copolymer...
