1.1 This standard ( Part 1 ) prescribes method for the determination of the creep strain of metal test samples subjected throughout their duration to nominally constant tensile load and constant temperature conditions in either single or multi-test sample creep testing machines for up to 100 000 h. It defines the properties to be determined and the terms used in describing tests and test samples.
1.2 This standard is applicable to interrupted and non-interrupted test, on test samples of circular and rectangular cross-section and also on test samples from tubes. It is applicable to creep tests in which strain is measured by an extensometer, and to creep test in which, strain above certain lower limiting values is determined by measurement at room temperature, during interruptions made for that purpose throughout the test.
1.3 The standard is applicable to the condition of heating the test sample in an electric resistance or radiation furnace in air or atmosphere pressure unless other media are specifically agreed upon in advance.
1.4 This standard is not applicable for conditions of rapid heating, rapid strain rates or too short times.
1.5 This standard does not cover the creep testing of notched test specimens.
