Metallic materials. Verification of the alignment of fatigue testing machines
| Published By | Publication Date | Number of Pages |
| BSI | 2012 | 42 |
This International Standard describes a method for verifying the alignment in a testing machine using a strain-gauged measuring device. It is applicable to dynamic uniaxial tension/compression, pure torsion and combined tension/compression plus torsion fatigue testing machines for metallic materials.
The methodology outlined in this International Standard is generic and can be applied to static testing machines and in non-metallic materials testing.
