在材料试验机的定期检定中,示值误差指标合格与否的确认是一项十分重要的工作,对这些指标的准确描述与理解将直接影响检定工作的质量。本文拟接着《中国计量》2011年第12期刊文和后续文章《材料试验机检定规程误差公式补充讨论》对相关规程示值相对误差公式、示值进回程相对误差公式的讨论,再对示值重复性相对误差公式谈一些看法。
In the periodic testing of material testing machine, it is very important to confirm whether the indication error index is qualified or not. The accurate description and understanding of these indexes will directly affect the quality of the verification work. This article will be followed by “China Metrology” 2011 the twelfth issue and follow-up article “material testing machine test procedures error formula supplementary discussion” on the relevant regulations indication error relative formula, the value of the return to the relative error formula discussion, Repetitive relative error formula to talk about some ideas.
