摘要
以ABS/PC塑料板为试验材料,采用DIN EN ISO 2039—1:2003《塑料硬度测定第一部分:球压痕法》中规定的方法,测试塑料板球压痕硬度值;依据JJF 1059.1—2012《测量不确定度评定与表示》,建立数学模型及对不确定度来源量化分析,对ABS/PC塑料板球压痕硬度测量结果进行了评定。ABS/PC塑料板测定结果为H=121 N/mm^(2),其中扩展不确定度为3.3 N/mm^(2),该不确定度主要来源于重复性测量。
Using ABS/PC Plastic as test material,measured on the basis of the methods of DIN EN ISO 2039—1:2003"Plastic-Determination of Hardness-Part I:Ball indentation method".According to JJF 1059.1—2012"Evaluation and Expression of Uncertainty in Measurement",the uncertainty of hardness of ABS/PC Plastic was calculated by constructing mathematical models and quantifying the source.The results of the hardness of ABS/PC plastic were indicated as:H=121 N/mm^(2),U=3.3 N/mm^(2),which was mainly from repeatability of measurement.
