首件检验

对每个班次刚开始时或过程发生改变后，生产线加工的第一或前几件产品进行的检验。检验的数量，可以根据不同企业或客户的要求制定。

一般来说，至少需要对连续生产的3-5件产品进行检验，合格后方可继续加工后续产品。在设备或制造工序发生任何变化，以及每个工作班次开始加工前，都要严格进行首件检验

First article inspection



Inspection of the first or first few products processed on the production line at the beginning of each shift or after process changes.

The quantity of inspections can be determined according to the requirements of different enterprises or customers.



Generally speaking, at least 3-5 consecutive products need to be inspected and qualified before continuing to process subsequent products.

Strict first article inspection is required before any changes occur to the equipment or manufacturing process, and before each work shift begins processing

首件检验的要求

首件检验采用三检制：自检、互检及专检。

送检的产品必须先由操作人员进行“自检”，然后再由班组长或同事进行“互检”，最后由检验员“专检”，确定合格后方可继续加工后续产品

首件检验不合格，需查明原因、采取措施，排除故障后重新进行加工、进行三检，直到合格后才可以定为首件

Requirements for First Article Inspection



The first article inspection adopts a three inspection system: self inspection, mutual inspection, and special inspection.



The products submitted for inspection must first undergo a "self inspection" by the operator, followed by a "mutual inspection" by the team leader or colleagues, and finally a "special inspection" by the inspector. After confirming that they are qualified, subsequent products can be processed



If the first article inspection is not qualified, it is necessary to identify the cause, take measures, and eliminate the fault before re processing and conducting three inspections. Only after passing the inspection can it be classified as the first article
