ISO 6892-2 Metallic Materials - Tensile Test - High Temperature Test Method

EUROLAB, with its state-of-the-art accredited laboratories and expert team, provides precise and fast testing services within the scope of ISO 6892-2 testing. This part of ISO 6892 specifies the method for tensile testing of metallic materials at temperatures higher than room temperature.

In this section of ISO 6892, two test rate methods are described. First, Method A is based on strain rates (including crosshead separation ratio) with tight tolerances (20%), and second, Method B is based on conventional strain rate ranges and tolerances.

Method A aims at minimizing the variation in test velocities and minimizing the measurement uncertainty of the test results as soon as strain rate sensitive parameters are determined.

The influence of test speed on the mechanical properties determined by the tensile test is normally greater at elevated temperature than at room temperature. Mechanical properties traditionally determined by tensile tests at elevated temperatures were determined at a slower strain or stress rate than at room temperature.

This part of ISO 6892 recommends the use of slow strain rates, but in addition, higher strain rates are permitted for certain applications, such as comparison with room temperature specifications at the same strain rate.

During discussions about test speed in the preparation of this part of ISO 6892, it was decided to consider deleting the stress ratio method in future revisions.
