LOW TEMPERATURE ELASTOMER TESTER


Low temperature testers such as TR Tester, Gehman Tester and Brittleness tester are used to determine the low temperature characteristics of rubber materials. The TR test according to ISO 2921 determines the low temperature characteristics by the temperature retraction procedure. The values TR and TR 10 are often used in material specifications.

The Gehman test according to ISO 1432, ASTM D1053 is used to determine the relative stiffness characteristics of vulcanized or thermoplastic rubbers over a temperature range, also called the Gehman procedure.

The Brittleness test according to ISO 812 determines either the lowest temperature at which materials do not exhibit brittle failure or the temperature where 50% of test pieces fail when subject to impact under specified conditions.

Low Temperature Elastomer Tester Products


TR Tester, ET 01-II

TR Tester, ET 01-II, for determination of low temperature characteristics by the temperature retraction procedure according to ISO 2921 and ASTM D1329. The values TR10 and TR30 are often used in material specifications. The software can present a curve with the elastic retraction up to 70 %.

Gehman tester, ET 02-II

Gehman Tester, ET 02-II, for determination of the relative stiffness characteristics of vulcanized or thermoplastic rubbers, also called the Gehman procedure. The test is done according to ISO 1432, ASTM D1053, or equivalent standards. The result is presented as the relative stiffness where the stiffness in RT is 1. If the test piece dimension are put into the software it can also calculate the modulus as a function of temperature.
