GB/T 36214的本部分规定了在60 ℃~180 ℃下使用有机洗脱剂，通过体积排除色谱法(SEC)测定聚合物平均分子量和分子量分布的方法。依据聚合物标样构建的校正曲线计算得到平均分子量和分子量分布，因此该测试方法属于相对法(参见附录A及GB/T 36214.1—2018的附录A)。

GB/T 3682的本部分规定了在规定的温度和负荷条件下测定热塑性塑料熔体质量流动速率(MFR)和熔体体积流动速率(MVR)的方法。方法A是质量测量方法，方法B是位移测量方法。通常，热塑性塑料材料标准参考本部分规定测定熔体流动速率的试验条件。附录A中列出了热塑性塑料常用的试验条件。 熔体体积流动速率特别适用于填充和非填充的热塑性塑料的比较，以及不同填充量的填充材料的比较。如果已知材料在试验温度下的熔体密度，则MFR可以由MVR的测定结果确定，反之亦然。 本部分也可用于流变行为受水解(断链作用)、缩聚和交联影响的热塑性塑料，但仅当这些影响及测试结果的重复性和再现性在可接受的范围内时才适用。 本部分不适用于在测试过程中流变行为受到显著影响的材料。这些情况下，可采用GB/T 3682.2。
