BS ISO 1352. Metallic materials. Torque-controlled fatigue testing
|Standard number:||21/30404149 DC|
|Status:||Draft for Comment|
This standard 21/30404149 DC BS ISO 1352. Metallic materials. Torque-controlled fatigue testing is classified in these ICS categories:
- 77.040.10 Mechanical testing of metals
This International Standard specifies the conditions for performing torsional, constant-amplitude, nominally elastic stress fatigue tests on metallic specimens without deliberately introducing stress concentrations. The tests are typically carried out at ambient temperature or an elevated temperature in air by applying a pure couple to the specimen about its longitudinal axis.
While the form, preparation and testing of specimens of circular cross-section and tubular cross-section are described in this International Standard, component and other specialized types of testing are not included. Similarly, low-cycle torsional fatigue tests carried out under constant-amplitude angular displacement control, which lead to failure in a few thousand cycles, are also excluded.
