实在找不到标准文件,请教下各位成品检验可否只检验外观呢,甚至如果取消成品检验违反了哪些条款呢

产品不同要求也是不同的,有的产品出厂国家标准是明确规定检验项的,对于没有明确要求的,要能够提供数据证明可控的无风险的。

检或不检,取决于对产品质量的信心程度。如果有数据支持(比如SPC数据),成品尺寸过程稳定且能力指数CPK/PPK大于1.33,这时已几乎没有不良品,再做一遍检查其实就是浪费,完全可以不检查或减少检查数量;如果没有或者现有数据不支持,则需要进一步评估

原则上,样品承认做全尺寸量测,做CPK分析,如能达到1.67就OK;正常量产后,特殊特性项,原则上都要检验,其它依据实际再评估。
