SC 5 – Draft comprehensive plan

Draft comprehensive plan of the rubber quality control phased transition to standards meeting ISO standard requirements was prepared at the request and with the participation of rubber, tire and rubber good producing companies, as well as by RF Government decisionon the import replacement. Please be aware with the Draft on here.

To implement the Draft SC 5/SC 6 (carbonblack) joint meeting was held on 2016.04.20. A number of decisions were taken, including that on the release of reference black pilot batch.

FSUE “ISR” specialists have already started to execute some sections

of the plan:

- 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;

- specifications were developed on some referenceing redients--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

priority tasks of the program of SR quality control phased transition to ISOand ASTM standard methodology.

Industrial referenc ematerials (IRMs) are in a wide use abroad in various applications to monitor product quality, including SR, black and mechanical rubber good manufactures.

They are also employed in specifying standard values of rubber quality through interlaboratory tests for stress-strainand rheology characteristics.

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. IRM release and certification is paramount for substitution

of expensive American ingredients and blacks.

The standard materials show more stringentr equirements for quality and stability during the storage and reproduction. In practice they are to be recorded in the State Register, so their costs are higher; they are generally used for arbitration tests and IRM checking.

At SC 5 meeting on 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.

You are welcome to participate in the discussionon the Draft concerning the updating and formation of standard technical documentation on rubberquality control, single for all producers and users, with allowance for ISO and ASTM standard requirements.
