Product Inspection Standard

What quality inspection standard do we use?

AQI Service uses the ANSI/ASQ Z1.4-2008 as its sampling inspection standard and acceptable level of quality. This method is widely used to decide whether to accept a production lot without checking every single item. This standard now has equivalents in all national and international standardization organizations such as BS6001, ABC105, ANSI/ASQ Z1.4, NFX 06-022, ISO 2859 and DIN 40080.

It offers the advantage of clearly defining the number of samples to be inspected from a given lot or consignment. It also suggests the maximum number of defective items allowed in the samples size unless specified by clients. the default Acceptable Quality Level is Level II.

Inspector randomly select a sampling size quantity (based on the AQL tables) to be inspected. then inspector inspect the sampling size and classify the defects into critical, major and minor defects.

According to the number of defects found for each type and according to the number of defects allowed (figures given by the AQL tables), we will advise you to accept or to reject your shipment.

Then it is up to you to make your own decision based on the information and recommendations we have provided to you.

We suggest that you discuss the findings with your vendor and the manufacturer and you ask him to pay attention/rework/re-produce/sort out the products.
