丁基橡胶门尼黏度标准物质的研制

Development of standard substance of butyl rubber Mooney viscosity

经过丁基橡胶的样品候选、均匀性检验、稳定性检验、定值、不确定度评估等系列工作,研制出了丁基橡胶门尼黏度国家标准物质,于2013年11月获得了国家质量监督检验检疫总局的批准。丁基橡胶门尼黏度标准物质定值结果在0.01的显著水平时数据间无异常值,呈现正态分布,各组数据间处于等精度,因此定值结果的总平均值即为门尼黏度标准物质的标称值。

On the basis of butyl rubber sample selection, uniformity test, stability test, standard value certification and uncertainty evaluation , the national standard substance of butyl rubber Mooney viscosity was successfully developed and approved by General Administration of Quality Supervision , Inspection and Quarantine of the People′s Republic of China in November of 2013.When the significant level was at 0.01 , the data of certified values of IIR standard substance showed a Gaussian distribution and equal precision , and no abnormal values were found in the result data , so that the total average of certified values were the standard values of Mooney viscosity standard substance at different measurement conditions.
