摘要
以乙丙丁三元共聚聚丙烯为丁烯含量标准物质定值样品,对丁烯含量测量不确定度的来源进行了分析和评定。结果表明,影响乙丙丁三元共聚聚丙烯丁烯含量标准物质不确定度的因素主要有样品均匀性、样品稳定性和各实验室定值结果的重复性。经过评定,乙丙丁三元共聚聚丙烯丁烯含量标准物质测定的不确定度为0.10,标称值为4.82±0.10。
The sources of uncertainty measurement for butane content of 1-butene-ethylene-propylene terpolymer reference material was evaluated. Evaluation of uncertainty measurement for butane content of 1-butene-ethylene-propylene terpolymer reference material was influenced by uniformity tests,stability tests and the repeatability of all laboratories results. Nominal value of butane content of 1-butene-ethylene-propylene terpolymer reference material was4. 82 ± 0. 10.
