What is ISO 289 ‑ 2 - Pre-vulcanization characteristics of rubber about?
ISO 289 ‑ 2 is the second part of an international multi-series standard for unvulcanized rubbers. ISO 289 ‑ 2 specifies the principle, apparatus, calibration schedule, preparation of test specimen, test temperature, procedure, precision for a test method that determines the pre-vulcanization characteristics of rubber which help in maintaining the rubber at a higher temperature.
