General inspection departments need to make judgments on each inspection item when inspecting products. The judgment results are divided into ACC and REJ, where ACC stands for acceptance and REJ stands for rejection.

By counting the ACC number and REJ number of each sub-item, and then comparing with the AQL acceptance standard, the judgment result of whether the whole batch of products is qualified is obtained.

Extended data:

IQC is the window for the company to deal with suppliers, and it is also the gateway to control the quality of suppliers. The operation mode of IQC is directly related to the quality cost of our products and our impression among suppliers.

① Strict sampling

Sampling inspection is a risk with statistical probability. This risk may miss the inspection of defective products and put them on the production line, or reject qualified products, thus indirectly causing losses to the company. Therefore, when sampling, we must try our best to make the sample reflect the quality of the mother.

In the sampling scheme, according to the current international or national standards, the risk rate can be controlled below 5%, but in the specific sampling process, due to personal preference, the randomness of the matrix may be insufficient, so special attention should be paid to rigor in the sampling method.

② Judge the quality objectively and fairly.

A.IQC personnel often contact with suppliers, forming an "emotional atmosphere", which is easy to form subjective consciousness during inspection, leading to different standards for judging suppliers.

B. Affected by personal mood, if you are in a good mood, you may be more serious, and your test judgment may be more cautious; Being in a bad mood may just be something you do at a glance.

C. Influenced by the personality of inspectors, impatient people tend to be subjective in their judgment, so they should pay attention to objectivity and fairness. If unqualified batches are put into the process and raw materials have problems, IQC personnel will take the responsibility first.

③ Respect suppliers.

④ Comprehensive factor judgment.

During the inspection, we sometimes encounter some conflicts in quality, time, cost and efficiency. For example, raw materials need to be put online urgently, but the inspection found that some "minor problems" could not be accepted according to the original standards. The company's procurement strategy is to adopt materials with lower prices, even if they are different from the original quality objectives, they may be accepted.

⑤ Try not to take special measures.

⑥ Clear identification during inspection.

Label identification is used to distinguish products to be inspected, defective products, qualified products, etc. , and it is best to stick a color label to show the difference.
