Abstract To better understand and reach consensus on a series of issues around the standard ISO 6892-1 and TENSTAND WP4 report, extensive experiments were conducted using 5 different methods with non-aging high-uniformity tensile reference materials. These tests were performed by 21 laboratories and a number of findings have been observed by analyzing the data collected from these tests. The findings suggested that the two reasons to recommend strain control method cited in TENSTAND WP4 report were not valid as the actual test conditions do not match the conditions in the report. A number of unjustified requirements in ISO 6892-1 were listed in this paper according to the findings. Four requests to update ISO 6892-1 were proposed for consideration.
