What is ISO 6892-1 about?
ISO 6892-1 specifies the method for tensile testing of metallic materials and defines the mechanical properties which can be determined at room temperature.
ISO 6892-1 guides you for testing the determination of the upper yield strength, lower yield strength, original cross sectional area and methods of verification of permanent set strength.
Who is ISO 6892-1 for?
ISO 6892-1 on method of test at room temperature is useful for:
- Metal workers
- Metallurgists, metallurgical engineers and material science engineers
- Welder fabricators
- Machine tool operators
- Mechanical engineers
- Composite manufacturers
Why should you use ISO 6892-1?
During discussions concerning the speed of testing in the preparation of ISO 6892, it was decided to recommend the use of strain rate control in future revisions. In ISO 6892-1, there are two methods of testing speeds available.
The first, method A, is based on strain rates (including crosshead separation rate) and the second, method B, is based on stress rates. Method A is intended to minimize the variation of the test rates during the moment when strain rate sensitive parameters are determined and to minimize the measurement uncertainty of the test results. Therefore, and out of the fact that often the strain rate sensitivity of the materials is not known, the use of method A is strongly recommended.
What’s changed since the last update?
BS EN ISO 6892-1: 2019 supersedes BS EN ISO 6892‑1:2016, which is withdrawn. There are some technical changes BS EN ISO 6892-1: 2019 has made with respect to BS EN ISO 6892‑1:2016. These include:
- Correction of the title of a standard in Clause 2
- Correction of the designation "coefficient of determination" ("coefficient of determination" instead of "coefficient of correlation")
- Correction of Formula (1)
- Wording in 10.3.2.1
- Wording in the key of Figure 9
