Dynamic test system for determination of flex and crack growth properties of rubber.

Standards :

DIN ISO 132

The hydraulic Tear Analyser measures fatigue and crack propagation on 1x10 elastomers with the system BAYER. The Tear Analyser represents an instrument, which allows the quantitative reproducible determination of differential crack propagation mechanisms under specific degradation parameters. [1] The possibility of testing up to 10 specimens at a time allows recording a sufficient data base for statistical evaluation in a time efficient manner.

The electromotoric Tear Analyser measures fatigue and crack propagation on 2x5 elastomer specimen with the system BAYER.

Force instrumented impact test with impact speed measurement and motorized drop height setting. The measurement runs automatically and the breaking energy is provided instantly after impact. The system can be fitted to meet various test scenarios from standard testing to individual component testing.

Determination of the temperature at which plastics that are not rigid at normal ambient temperature exhibit brittle failure under specified impact conditions.

Standards :

ISO 812, ISO 974, ASTM D 746

This test method covers the determination of the susceptibility of ethylene plastics to environmental stress-cracking. Under certain conditions of stress and in the presence of environments such as soaps, wetting agents, oils, or detergents, ethylene plastics may exhibit mechanical failure by cracking.

Bent specimens of the plastic, each having a controlled imperfection on one surface, are exposed to the action of a surface-active agent. The proportion of the total number of specimens that crack in a given time is observed.
