GB/T 2941-2025 "Rubber, Physical Test Methods General Procedures for Specimen Preparative and Adjustment" is an important basic standard in the field of rubber physical performance testing in our country. The standard is equivalent to the ISO 23529:2016 international standard, which comprehensively regulates the general procedures for the preparation, measurement, marking, storage and adjustment of rubber samples, as well as the selection of environmental conditions during the test. The standard focuses on strengthening the temperature, Humidity and time interval control requirements during sample processing, and significantly improves the conformity and comparability of test results between different laboratories. As a replacement version of GB/T 2941-2006, the new standard will be officially implemented on November 1, 2025 and will be managed by the National Rubber and Rubber Standardization Technical Committee.
