烧结普通砖抗压强度测量结果的不确定度评定

Evaluation on the uncertainty in measuring the compressive strength of common fired bricks

GB/T2542-2003《砌墙砖试验方法》给出了烧结普通砖抗压强度测量结果的评定方法,没有给出重复性限和再现性限。通过对烧结普通砖抗压强度测量结果的不确定度评定,给出一种评价测量结果分散程度的方法。

The national standard of Test Methods for Wall Bricks （GB/T 2542-2003） gives a evaluation method on the compressive strength of common fired bricks, but not repeatability limit and reproducibility limit. Through evaluating the uncertainty of compressive strength, this article presents an evaluation method on dispersion of measuring result.
