Application Summary AI generated

This standard specifies a method for determining the indentation hardness of vulcanized or thermoplastic rubber using a portable IRHD (International Rubber Hardness Degrees) pocket meter. It is applied in quality control and field testing scenarios where a quick, non-destructive hardness measurement is needed on finished rubber products, such as seals, hoses, or tire components, without requiring a laboratory benchtop instrument. The method is particularly useful for on-site inspection of large or installed rubber parts where traditional bench-mounted durometers are impractical.
