What is BS 5293-20 - Method for evaluation in styrene-butadiene rubbers about?
BS 5293 is a series on sampling and testing carbon black for use in the rubber industry. Carbon black is a material produced by the incomplete combustion of heavy petroleum products such as fluid catalytic cracking tar, coal tar, ethylene cracking tar, or vegetable matter.
Carbon black is a form of paracrystalline carbon that has a high surface-area-to-volume ratio, albeit lower than that of activated carbon. BS 5293-20 specifies standard materials, equipment, and processing methods for evaluating carbon black in styrene-butadiene rubbers (SBR).
Who is BS 5293-20 - Method for evaluation in styrene-butadiene rubbers for?
BS 5293-20 on method for evaluation in styrene-butadiene rubbers is useful for:
- Rubber manufacturing industries
- Quality control personnel
- Research and development manufacturers
Why should you use BS 5293-20 - Method for evaluation in styrene-butadiene rubbers?
Carbon black is mainly used as a reinforcing filler in tires and other rubber products. In plastics, paints, and inks, carbon black is used as a colour pigment. It is used in some places, such as the EU, as a food colourant if produced from vegetable matter (E153). The standard test formula is given in BS 5293-20. The materials are NIST standard reference materials as indicated in BS 5293-20 or are in accordance with equivalent national or International Standards.
The test report includes a reference to BS 5293-20, all details necessary for the identification of the sample, the reference materials used, including the Mooney viscosity of the SBR, the vulcanizing temperature and times used in BS 5293-20, any unusual features noted during the determination, any operation not included in BS 5293-20 or in the International Standards to which reference is made, as well as any operation regarded as optional, the results and the units in which they have been expressed and the date of the test. Using BS 5293-20 you can specify standard materials, equipment, and processing methods for evaluating carbon black in styrene-butadiene rubbers.
