| 摘 要： | 以低顺橡胶P30AF为例，依据ASTMD5668-2009在电热恒温鼓风干燥箱中进行了挥发分含量测试，对其挥发分含量测试过程中的不确定度分量进行了分析和评定，并给出了具体数值。结果表明：低顺橡胶P30AF挥发分含量X=0．67％，扩展不确定度U=0．09％，包含因子k=2，置信概率p=95％；其测量不确定度主要来源为由样品的不均匀性引入的不确定度。

| Abstract: | Volatile content of low-CIS rubber was tested according to ASTM D5668--2009 with P30AF rubber as example, and the uncertainty factors were analyzed and evaluated during the testing process. The results show that the volatile content of low-CIS rubber P30AF X= 0. 67%, with the expanded uncertainty U： 0. 09% coverage factor k= 2, confidence probability p≈ 95 %, and the main source of the uncertainty in the volatile content testing process was the inhomogeneity of the sample. |
