oftheplan:

- draft specifications on reference black pilot batch were developed in August and sent for approval to the Institute of Hydrocarbons Processing of Siberian Branch Russian Academy of Scinces;

- specificationsweredevelopedon somereferenceingredients--zinc oxide, stearic acid, accelerators, in compliance with ASTMD 5900 requirements;

- SC 5 specialists are preparing the draft standard “Rubber. Referencematerials.Development, production and certification procedures, allowing for ASTM 4678 and ASTM 5900 provisions.

Release and certification of reference ingredients first batches are

The use of industrial reference ingredients and blacks provides the unity of the measurements and testing conducted by rubber producers and users, markedly reduces mutual claims in quality, improves the result accuracy and reproducibility.IRMreleaseandcertificationisparamountforsubstitution

AtSC 5 meetingon 27 October2016 the participants are invited to consider measuresto implementthe Comprehensive plan, in particular, the steps of elaboration, release and certification of industrial reference ingredients and blacks (of IRB type), as well as measures to providewith domestic instrumentation and rigs, such as molds, cutters, sharpening devices, etc.
