Evaluation of comparative results of styrene-butadiene rubber Mooney viscosity

According to GB/T 1232.1-2000,producing,processing,researching and testing of the synthetic rubber of 26 laboratories were organized to contrast the Mooney viscosity data of styrene-butadiene rubber by robust statistical method.The laboratories taken part in this work reflected the testing level of the Mooney viscosity in the synthetic rubber industry;the quality inspection institutions of the national and industry showed higher-level,and the laboratories of the scientific research development had an obvious advance on testing;laboratories of producing and processing industries can reach the testing requirements.Compared with the past,The testing level of all the laboratories had different improvement.The laboratories with the(|Z|) lower and laboratory accreditation were chose as qualified value for preparation of standard material of the Mooney viscosity.
