Rubber Testing & control
Quality assurance through advanced rubber testing
When testing and inspecting rubber and rubber parts there are several different test methods to use depending on the properties to be evaluated. Below we briefly describe the most common test methods.
Preparation
When testing rubber, one starts either from uncured rubber or cured rubber products. The testing can also relate to the uncured or cured state. Specimen preparation is a very important part of the actual testing as it ensures that the test result does not reflect the specimen preparation more than the actual properties of the rubber.
Even conditioning the sample material is an important part of the sample preparation itself.
