This is a fundamental standard for regulating the determination of vulcanization characteristics. It systematically introduces the general methods, basic principles, and core requirements for measuring the vulcanization characteristics of compounded rubber using a vulcameter (rheometer). As the foundational guideline for the entire series of methods, it provides a technical framework for obtaining key process parameters such as scorch time and vulcanization rate by continuously measuring the torque-time curve of rubber during the vulcanization process. The core testing instrument applicable to this standard is the vulcameter (or rubber vulcanization rheometer), and it covers specifications for its calibration, sample preparation, test conditions (such as temperature control), and other aspects to ensure the consistency and comparability of the determination results.
