摘 要:檢驗(yàn)員在對(duì)檢驗(yàn)數(shù)據(jù)的處理與判定時(shí),應(yīng)根據(jù)產(chǎn)品標(biāo)準(zhǔn)中的具體要求,分別采用全數(shù)值比較法或修約值較法。但同時(shí),應(yīng)根據(jù)參數(shù)指標(biāo)的重要程度不同,將檢測(cè)結(jié)果精密度一并考慮,這樣檢測(cè)結(jié)果會(huì)更客觀、合理。

[Abstract]:The inspector when to examines the data processing and the determination,should act according to in the product standard the specific request,separately uses the entire value comparison test or repairs approximately the value method.But simultaneously, should actaccording to the parameter target the important degree different,will examines the result accuracy one and the consideration,like this will examine the result to be able more objective,to be reasonable.
[Key Words]:Examination data processing and determination;Entire value comparison test;Repairs approximately the value comparison test;Accuracy.
產(chǎn)品質(zhì)量監(jiān)督檢驗(yàn)部門發(fā)出的檢驗(yàn)報(bào)告是具有法律效力的。因此,對(duì)于檢驗(yàn)報(bào)告來說,檢驗(yàn)結(jié)果不但要準(zhǔn)確,而且還要科學(xué)。但在實(shí)際工作中,我發(fā)現(xiàn)有些檢驗(yàn)員對(duì)檢驗(yàn)報(bào)告中檢驗(yàn)結(jié)果的數(shù)據(jù)處理與判定,一直存在著不同的見解。其差異在于對(duì)處于臨界值的測(cè)定結(jié)果的處理。有的認(rèn)為不能修約,有的贊成修約。贊成修約的當(dāng)中又有的認(rèn)為修約位數(shù)應(yīng)與相應(yīng)標(biāo)準(zhǔn)中質(zhì)量指標(biāo)的有效數(shù)字位數(shù)相同;有的則認(rèn)為修約后的有效數(shù)字或小數(shù)點(diǎn)位數(shù)應(yīng)比標(biāo)準(zhǔn)值有效數(shù)字或小數(shù)點(diǎn)位數(shù)多一位。而這些見解與GB/T8170-2008標(biāo)準(zhǔn)“數(shù)值修約規(guī)則與極限數(shù)值的表示和判定”中的有關(guān)規(guī)定是不相符或不完全相符的。為了能夠更好地解決上述分歧。首先,闡述幾個(gè)比較重要的概念:(1)異常值:就是的所得的測(cè)定值中,個(gè)別明顯偏離其它檢測(cè)值的數(shù)據(jù)。(2)極限值:標(biāo)準(zhǔn)中規(guī)定的質(zhì)量指標(biāo)數(shù)值。(3)臨界值:臨近界限值的實(shí)測(cè)數(shù)值,即由于數(shù)字修約影響其單項(xiàng)結(jié)論合格與否的實(shí)測(cè)數(shù)值。其次,讓我們討論依據(jù)GB/T8170-2008標(biāo)準(zhǔn)對(duì)檢驗(yàn)數(shù)據(jù)中臨界值進(jìn)行處理和判定的問題。……
