Preparation of mooney viscosity of butadiene rubber(BR) 9000

The value of butadiene rubber was defined according with standard material value after preparated,passed by uniformity and stability measure by laboratories.The dispose of proceed of standard material value was used to judge of unusual numbers,inspect of distributed numbers,testy of equal precision,appraised of uncertainty.When remarkable level a=0.05 of standard material of mooney viscosity after tested by laboratory,the number was certainty,normal distribution and equal precision,the value of standard was(45.6±0.5)ML(1+4)100 ℃.Successful preparation of standard material should be supported to control of produce,trade of goods and arbitration of quality.
