注:脚本执行有风险,对于客户正式环境请在研发指导下执行。

检验为确定产品或服务的各特性是否合格,测定、检查、试验或度量产品或服务的一种或多种特性,并且与规定要求进行比较的活动。

计数检验:关于规定的一个或一组要求,或者仅将单位产品划分为合格或不合格,或者仅计算单位产品中不合格数的检验。

可接受合格质量水平:简称AQLAcceptable Quality Level,是一个生产企业能够接受的最抵的不合格率,是企业能够达到的平均质量水平。当企业产品不合格率低于AQL时,即为合格区域。

质检方案质检系统的重要基础设置,相当于一个质检单质检内容的模版,定义了一个质检过程要检验哪些指标,分几步执行,每个指标的标准值和检验方法。

严格程度用于调整型抽检方案。一般情况下,抽样检验采用正常检验。但是根据产品质量的变动情况,应适时调整检查的严格程度,以保护供需双方的利益。调整型质检方案的严格程度分为三种:正常、放宽、加严。

单位产品单位产品也可以称为个体,是构成产品总体的基本单位。在检验中,一般将每个样品叫做一个单位产品。单位产品可以自然地划分,如一批灯泡中的每只灯泡;有时不能自然地划分,如在不同的要求下,一尺布,一丈布以致一丈布都可以作为一单位产品。

样本样本由取自产品总体的单位产品(即个体)组成。根据统计原理,构成样品的各个单位产品应随机地取自总体,并相互独立,以便使样本的统计特性能够较好地反映总体的分布特性。样本中单位产品的数目称为样本容量或样本大小,一般用n表示。

交验批:提供检验的产品总体称为交验批。交验批中单位产品的数量称为批量,当批量有限时常用N来表示。

合格判定数Ac和不合格判定数Re: 在抽样方案中,预先规定的判定批产品合格的样本中最大允许不合格数,称为合格判定数AcAcceptance Numben);预先规定的判定批产品不合格的样本中最小不合格数称为不合格判定数ReRejection number)。

批不合格率p和过程不合格率Þ批不合格率是批中不合格品数D占整个批量N的比率,一般用百分比数来表示,即:p=D/N。过程不合格率Þ是指批产品的平均不合格率。过程不合格率Þ可以用这些批产品的样本抽验结果来估计。设共有k批产品,从每批产品中抽取的随机样本的大小依次为n1,n2,n3,…nk;其中的不合格品数依次为d1,d2,d3,…dk; Þ=d1+d2+d3+…+dk/n1+n2+n3+…+nk)。

合格质量水平AQL合格质量水平AQL也称为可接受质量水平,是供需双方共同认为可以接收的连续交验批的过程平均不合格率的上限值。

 

检验水平(IL):也叫检验级别。在MIL-STD-105D中,将检验级别分为三个一般检验级别(Ⅰ、Ⅱ、Ⅲ)和四个特殊检验级别(S-1S-2S-3S-4
