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.
ISO 289‑2 specifies a method for determining the pre-vulcanization characteristics of compounded rubber.
Who is ISO 289‑2 - Pre-vulcanization characteristics of rubber for?
ISO 289‑2 on pre-vulcanization characteristics of rubber is useful for:
- Manufacturer of automotive, shoes
- Rubber processing industries
- Manufacturer of insulation materials
- Manufacturer of rubber products
Why should you use ISO 289‑2 - Pre-vulcanization characteristics of rubber?
Unvulcanized rubber is used in improving the elasticity of rubber at high temperatures, which results in sustaining the rubber in different conditions.
ISO 289‑2 helps in changing the mooney viscosity of the rubber compound with running time at a specified temperature. The units are recorded at a particular time when the Mooney viscosity increases. The calibration schedule mentioned in ISO 289‑2 is useful in the inspection of calibrated items which helps you in specifying these calibrate items are in good condition or not.
ISO 289‑2 specifies the test procedures and calibration schedule which helps you in conducting the tests. This method determines the pre-vulcanization characteristics of rubber that can help you in maintaining the long-compounded rubber at high temperatures.
What’s changed since the last update?
BS ISO 289‑2:2020 supersedes BS ISO 289‑2:2016. The main change in BS ISO 289‑2:2020 compared to the previous edition is that the precision statement in Annex B has been updated after a new ITP was performed.
