ISO3601-5: Suitability of elastomeric materials for industrial applications

ISO3601-5 specifies the appropriateness of various rubber materials which may be used for the production of O Rings intended for use in industrial applications. ISO3601-5 also specifies the capability of the materials to fulfil many of the demands related to fluid power elements and systems. This includes fluid compatibility and temperatures. The manufacturer and customer should both agree on the physical properties.

O Rings synthetic elastomers include:

  • NBR – Nitrile / Acrylonitrile-butadiene – IRHD 70, 90
  • FKM – Fluorocarbon – IRHD 70, 80
  • EPDM – Ethylene propylene diene – IRHD 70, 80
  • VMQ – Silicone – IRHD 70
  • ACM – Polyacrylate – IRHD 70
  • HNBR – Hydrogenated Nitrile – IRHS 70, 80

Depending on installation other materials and hardnesses may be more suited.
