饰面人造板静曲强度的不确定度评定

Evaluation of Uncertainty in Static Bending Strength of Veneered Wood Based Panels

测量不确定度是对于误差分析中的最新理解和阐述,是测量结果质量的重要指标。依据GB/T 17657—2013《人造板及其饰面板理化性能试验方法》4.7节静曲强度和弹性模量测定(三点弯曲),对其测量的过程的不确定度进行分析与评定。

Measurement uncertainty is the latest understanding and elaboration in error analysis,and it is an important indicator of the quality of measurement results.According to GB/T 17657-013 Test methods for Physical and Chemical Properties of Woodbased Panels and Their Decorative Panels,4.7 determination of static bending strength and elastic modulus(three-point bending),the uncertainty of the measurement process was analyzed and evaluated.
