The rubber durometer chart below gives you an idea of the rubber hardness that you want for your application.

Rubber o ring testing.

Part of the specification includes tension testing for determining the breaking force tensile strength and ultimate elongation of an o ring. D1414 15 standard test methods for rubber o rings relative density compression set test aging test mold shrinkage products and services standards publications standards products. Load the o ring onto the ball bearing spool grips by bringing the grips in close proximity to each other so as not to stretch the sample during loading. The company has decades of experience with all types of o rings and has been testing these products to make sure quality stays as high as possible.

Technical handbook o rings how to properly deal with hardness and compression set hardness testing is the easiest test to carry out on o rings but a proper interpretation of the hardness may be difficult. Generally most rubber materials fall under the rubber durometer scale of shore a. Astm d1414 15 standard test methods for rubber o rings. Thus if you need a rubber or o ring durometer that feels like a running shoe sole review our rubber hardness chart below then pick shore 70a.

Different industries and different situations often require different products so they have set up an oring testing lab to make sure the products first the recruitments of the industries. The hard ness commonly mentioned in the various data sheets refers to the standard measuring method by din or astm. Within the field of rubber and o ring test method eriks is leading for practical all industries. The tension test is intended to be performed on a universal testing machine tensile testing machine.

Tests measuring compression aging properties sealing properties and seal design help engineers and designers to understand the performance of their products in service. Astm d1414 rubber o rings tensile strength. Ardl provides a wide range of capabilities specific to the testing of o rings and o ring material. Active standard astm d1414 developed by subcommittee.

Companies like eriks design and develop specific o ring and rubber parts often in close cooperation. We can assist with rapid gas decompression high pressure high temperature testing dynamic testing tensile. Chemical resistance guide o ring calculator unit converter bellow selector rubber profile price calculator anti vibration selector rubber testing eriks possesses a complete range of equipment and know how for testing elastomer materials and rubber compounds. Prior to testing store the o ring specimens at 23 2c for at least 30 minutes.

A test report on a rubber compound which is being considered for use in o rings or for any other type of elastomer seal is of value only if the user understands how to interpret and utilize the data it contains. This brief guide is intended to explain the various terms used in common elastomer test reports and to assist the reader in relating material test results to.
