For rubber materials there are four important standardised test methods for Low Temperatures:

  • TR test according to ISO 2921
  • Gehman test according to ISO 1432
  • Brittleness test according to ISO 812
  • Low Temperature Compression Set according to ISO 815-2

TR Tester, ET 01

TR Tester, ET 01-II, for determination of low temperature characteristics by the temperature retraction procedure according to ISO 2921 and ASTM D1329.

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.

Brittleness Tester, ET 05-II

Elastocon Brittleness Tester, ET 05-II, for automatic determination of Brittleness point according to ISO 812, ISO 974, ASTM D746 and ASTM D2137.

Combined low temperature testers

The TR Tester, Gehman Tester and Brittleness Tester can be combined using the same base unit and a rig changing system.

Automatic cooling with liquid nitrogen, ET 01.02

The automatic cooling with liquid nitrogen, ET 01.02, consists of both the cryogenic vessel for the storing of liquid nitrogen and the special valve and hose that is needed for the connection between the vessel and the Low Temperature Tester.

Low Temperature Compression Set Rig, EV 09

EV 09 is a rig for testing compression set at low temperatures according to ISO 815-2 or other technically equivalent standards.

Software for Low Temperature Compression Set, LTCS, EC 10

The software for Low Temperature Compression Set, LTCS, EC 10, can monitor the temperature during the test time and records the recovery when the test piece is released.

Conversion kit for freezers, ET 03.01-x

With the ET 03.01-x conversion kit all of Elastocon’s laboratory freezers can be adapted for testing either in Low Temperature Compression Set with our EV 09 rig or in Stress Relaxation with our EB 02 rig.
