Frequently Asked Questions
ISO/TC 164/SC 1/WG 2 is a Subcommittee within the International Organization for Standardization (ISO). It is named "Creep and stress relaxation testing". This committee has published 2 standards.
ISO/TC 164/SC 1/WG 2 develops ISO standards. Currently, there are 2 published standards from this subcommittee.
The International Organization for Standardization (ISO) is an independent, non-governmental international organization that develops and publishes international standards. Founded in 1947 and headquartered in Geneva, Switzerland, ISO brings together experts from 170+ member countries to share knowledge and develop voluntary, consensus-based standards that support innovation and provide solutions to global challenges.
A Subcommittee (SC) in ISO operates under a Technical Committee and focuses on a specific subset of the TC's scope. Subcommittees develop standards and technical specifications in their specialized area, reporting to their parent Technical Committee. They may also have working groups for detailed technical work.
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.

ISO 204:2009 specifies the method for the uninterrupted and interrupted creep tests and defines the properties of metallic materials which can be determined from these tests, in particular the creep elongation and the time of creep rupture, at a specified temperature. The stress rupture test is also covered, as is the testing of notched test pieces.
