随着生产水平及闹钟质量的提高,对闹钟成品及零部件的质量不断提出新的要求。八十年代初,我厂在同行业之中最先采用美国海军抽样办法即GB2828—87逐批检查计数抽样程序。 下面我们就以机械闹钟关键部件摆轮的抽样办法为例做简单介绍。 检查批:为实施抽样检查汇集起来的单位产品。 批量:批中所包含的单位产品数。
With the improvement of the production level and the quality of the alarm clock, new requirements are constantly put forward on the quality of the alarm clock finished product and the parts and components. The early eighties, I plant in the industry among the first to use the US Navy sampling that GB2828-87 batch inspection count sampling procedures. Below we will take the mechanical components of the alarm clock as the key components of the sampling method to do a brief introduction. Inspection Lot: The unit product collected for the implementation of sampling inspection. Batch: The number of units included in the batch.
