GB/T 1689 is the Chinese national standard for determining the abrasion resistance of vulcanized rubber with an Akron abrasion machine. The current edition is GB/T 1689-2014, a recommended national standard in force since 1 June 2015.
Rubber compounders and labs supplying parts to Chinese specifications cite GB/T 1689 when a material specification or customer document calls for Akron abrasion results. Labs keep specimen preparation, conditioning and machine settings consistent across a test program. Before testing, labs confirm the edition and any requirements set out in the product or material specification they work to.
Akron-type abrasion machines such as our Akron abrasion tester are used for testing vulcanized rubber to GB/T 1689. If you need help matching GB/T 1689 requirements to your parts or setup, contact our team.
