GB/T 9580-2009 stipulates the identification method of standard reference carbon black. The standard clarifies the whole process from Sample Handling, testing items to data evaluation, and accurately determines and compares key performance indicators such as particle size, structure, oil absorption value of standard reference carbon black to determine whether it meets the standard requirements. Provide unified identification criteria for carbon black production, scientific research and related testing institutions to ensure the stability and reliability of standard reference carbon black mass, lay a solid foundation for various types of carbon black performance comparison, quality control and new Product Research & Development, and effectively promote the standardization development of carbon black industry.
