ASTM Testing Methods for Vulcanised Rubber or Products that we conduct or get it done from external laboratories

  • ASTM D395 – Compression Set Test, Rubber Products
  • These test methods cover the testing of rubber intended for use in applications in which the rubber will be subjected to compressive stresses in air or liquid media. They are applicable particularly to the rubber used in machinery mountings, vibration dampers, and seals.

  • ASTM D412 – Tension Properties of Vulcanized Rubbers
  • This is the most common standard for determining the tensile properties of Vulcanised Rubber and Thermoplastic Elastomers.

  • ASTM D471 – Volume Change, Effects of Liquid Test
  • This standard is used to evaluate the comparative ability of Rubber to withstand the effects of liquids

  • ASTM D1149 – Ozone Test
  • This test method covers the estimation of the resistance of vulcanized rubber to cracking when exposed to an atmosphere containing ozone. The rubber specimens are kept under a surface tensile strain, and the ozone content or partial pressure in the test chamber is maintained at a fixed value.

  • ASTM D573 – Deterioration in an Air Oven
  • This test method covers a procedure to determine the influence of elevated temperature on the physical properties of vulcanized rubber. The results of this test method may not give an exact correlation with service performance since performance conditions vary widely. This test method may, however, be used to evaluate rubber compounds on a laboratory comparison basis.

  • ASTM D624 – Tear Strength of Conventional Vulcanized Rubber
  • This test method describes procedures for measuring a property of conventional vulcanized rubber and thermoplastic elastomers called tear strength.

  • ASTM D865 – Deterioration by Heating in Air
  • This test method covers a procedure to determine the deterioration induced by heating rubber specimens in individual test tube enclosures with circulating air. This isolation prevents cross contamination of compounds due to loss of volatile materials (for example, antioxidants) and their subsequent migration into other rubber compounds (specimens). The absorption of such volatile materials may influence the degradation rate of rubber compounds.

  • ASTM D1414 – Complete Testing of O-rings
  • These test methods describe the procedures for determining the physical properties of O-rings and changes in these properties due to aging.

  • ASTM D2137 – Brittleness Temperature
  • These test methods cover the determination of the lowest temperature at which rubber vulcanizates and rubber-coated fabrics will not exhibit fractures or coating cracks when subjected to specified impact conditions.

  • AASTM D2137 – Brittleness Temperature
  • These test methods cover procedures for testing the static adhesion strength of rubber to rigid materials (in most cases metals).

  • ASTM D2240 – Durometer Hardness
  • 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, elastomeric materials, cellular materials, gel-like materials, and some plastics is also described.

There are many more ASTM Standards for Rubber Products, which are product specific and are conducted when needed.
