Metallic materials - Verification of the alignment of fatigue testing machines

This International Standard describes a method for verifying the alignment in a testing machine using a straingaugedmeasuring device. It is applicable to dynamic uniaxial tension/compression, pure torsion and combinedtension/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 machinesand in non-metallic materials testing.

ZOOM ON ... the Requirements department
To comply with a standard, you need to quickly understand its issues in order to determine its impact on your activity.

The Requirements department helps you quickly locate within the normative text:
- mandatory clauses to satisfy,
- non-essential but useful clauses to know, such as permissions and recommendations.

The identification of these types of clauses is based on the document “ISO / IEC Directives, Part 2 - Principles and rules of structure and drafting of ISO documents ”as well as on a constantly enriched list of verbal forms.
