| 摘 要： | 依据GB/T 7124-2008《胶粘剂拉伸剪切强度的测定》,以环氧树脂结构胶为例,对胶粘剂拉伸剪切强度测量结果的不确定度分量进行了分析和量化,计算了合成标准不确定度和扩展不确定度。当环氧树脂结构胶的拉伸剪切强度为28.8 MPa时,扩展不确定度为1.0 MPa(k=2)。

| Abstract: | Aaccording to the test method GB/T 7124 - 2008 Adhesives Determination of Tensile Lap - Shear Strength of Rig- id - to - Rigid Bonded Assemblies, the tensile lap - shear strength of adhesive was determined. The main sourees of uneertainty resul- ted from the determination process were discussed and calculated. The expanded uncertainty of measurement was 1.0 MPa, as the de- teetion result of tedsile lap - shear strength of adhesive was 28.8 MPa. |
