Low temperature testers

摘要

The low temperature properties of rubber materials are said to be very important, especially for rubber products used in colder climates. The requirements for these properties have long been included in specifications, especially in the automotive industry. Rubber materials testers are provided for four standardized test methods for low temperatures. The TR test according to ISO 2921 method determines the low temperature characteristics by the temperature retraction procedures. Software can present a curve with the elastic retraction up to 70%. The Gehman test according to ISO 1432 measures the relative stiffness as a function of the temperature.
