Metallic materials - Uniaxial creep testing in tension - Method of test

This document specifies the methods for:a)    uninterrupted creep tests with continuous monitoring of extension;b)    interrupted creep tests with periodic measurement of elongation;c)    stress rupture tests where normally only the time to fracture is measured;d)    a test to verify that a predetermined time can be exceeded under a given force, with the elongation or extension not necessarily being reported.NOTE       A creep test can be continued until fracture has occurred or it can be stopped before fracture.

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.
