Preface

This document is in accordance with the provisions of GB/T 1.1-2020 "Guidelines for standardization work Part 1.Structure and drafting rules for standardization documents" Drafting. This document replaces GB/T 9580-2009 "Identification method of standard reference carbon black". Compared with GB/T 9580-2009, except for the structural adjustment In addition to the integration and editorial changes, the main technical changes are as follows. --- Added "The remaining carbon black samples after sampling shall be used as backup samples and properly stored until the identification work is completed." (see 5.2); --- Change the standard reference carbon black sample to "2 kg" (see 5.3, 4.3 of the.2009 edition); --- Added "Standard reference carbon black (SNs) for chemical item testing" (see 6.1); --- Change “physical and chemical properties test” to “standard reference carbon black (IRCs) for physical test” (see 6.2, 5.3 of the.2009 edition); --- For physical test items, only the “iodine absorption value” and “oil absorption value” are retained for standard reference carbon blacks (IRCs) (see Table 3, Table 1 of the.2009 edition); --- Deleted "Recommended physical and chemical performance tests" (see 5.5 of the.2009 edition); --- Change the sample number to 6 (see Table 6, Table 5 of the.2009 edition). Please note that some of the contents of this document may involve patents. The issuing organization of this document does not assume the responsibility for identifying patents. This document was proposed by the China Petroleum and Chemical Industry Federation.
