摘　　要：对聚苯乙烯泡沫塑料(XPS)板按GB/T8813-1988进行了压缩强度的测试。依据JJF1059-1999分析了试验中对结果产生影响的各项因素,对测量结果的不确定度进行了计算和评定,并就相关问题展开了讨论。结果表明,此类测量存在相对较大的不确定度,其中试样长、宽方向的尺寸偏差和相对形变的取值为主要的影响因素。The compression strength of polystyrene foam was measured according to GB/T8813-1988. Depending on the standard of JJF1059-1999, the measurement uncertainty was calculated and evaluated, the effective factors in the test were analysized. It showed that in such measurements there was high uncertainty from the dimention tolerance and relative distortion.
