ISO 1817 – Swelling of Rubber, Vulcanized or Thermoplastic – Determination of the Effect of Liquids
Natural rubbers are often vulcanized (cross linked) to improve their thermal and mechanical properties. When a vulcanized rubber is exposed to a lubricant, the rubber may absorb or react with the lubricant. This test determines changes in hardness, tensile strength, volume and elongation that result from the exposure of rubber to lubricants. This test may be used for both for vulcanized natural rubbers and synthetic elastomers.
The rubber is cut into the proper sized coupons and immersed in the lubricant for the test time at the test temperature. Reported are the changes in properties as requested, which may include swelling, hardness, tensile strength, elongation and flexural stability.
