1 Scope

This Standard specifies requirements and test methods, inspection rules, marks, packaging, transport and storage for styrene-butadiene rubber (SBR) 1500,1502 [i.e., styrene-butadiene rubber, hereinafter referred to as styrene- butadiene rubber (SBR) 1500, 1502]. This Standard is applicable to styrene-butadiene rubber (SBR) 1500 and styrene-butadiene rubber (SBR) 1502 that take butadiene and styrene as monomers, compound soap of potassium rosin acid soap and fatty acid soap, or disproportionated potassium rosin soap as emulsifier, that is produced through low-temperature emulsion polymerization, where styrene-butadiene rubber (SBR) 1500 adds color-changing anti-aging agent and styrene- butadiene rubber (SBR) 1502 adds color non-discoloring anti-aging agent.

Under normal circumstances, mixed-refining rubber Mooney viscosity, 300% fixed stress, tensile strength, elongation at break and vulcanization characteristics are tested at least once a week. Ash content is subjected to type inspection at least once a month. Exit-factory inspection items for styrene-butadiene rubber (SBR) 1500, 1502 are volatile content, organic acid, soap, combined styrene, raw rubber Mooney viscosity. 4.3 Batching rules and sampling scheme 4.3.1 Batching rules Styrene-butadiene rubber (SBR) 1500, 1502 are batched by products of same production line, of same raw material, of same designation produced by same technique. Production plant may also batch according to a certain production cycle. Each batch does not exceed 300t. Styrene-butadiene rubber (SBR) 1500, 1502 are inspected and accepted in batches. 4.3.2 Sampling scheme Conduct sampling according to GB/T 19187-2016. Production inspection can be sampled online. 4.4 Rules for determination Styrene-butadiene rubber (SBR) 1500, 1502 shall be subjected to exit-factory inspection that is performed by quality inspection department according to test method specified in this Standard, according to mixed laboratory sample specified in 3.4 of GB/T 19187-2016. Make determination on product quality according to inspection results and technical requirements in Table 1. When any item in exit-factory inspection results fails to meet technical requirements specified in this Standard, it shall take remained sample for re- inspection for failed item. If re-inspection results do not meet requirements, it shall re-sample from double packaging units for re-inspection. Use re- inspection results as basis for quality determination of this batch of products.
