Our professional inspection services are conducted according to the worldwide acknowledged international quality control standards. During inspection, product sample size is randomly selected according to the well-known international standard MIL-STD-105E, ANSI/ASQC Z1.4, MIL-STD-105, BS6001, ISO 2859, DIN 40080. After the selection of product samples from the shipment lot, the inspection will be performed according to the Acceptable Quality Level (AQL) standard.

AQL standard refers to the maximum number of defective that could be considered acceptable during the random sampling of an inspection. The Defects that are found during inspection are classified into 3 levels: Critical, Major and Minor. The AQL level should be agreed between buyer and supplier before production commences.

Acceptable Quality Level (AQL) sample inspection methods have been proven to be an accurate statistics over a long run. However, the quality level of merchandise at destination might be lower than that of the pre-shipment inspection result. This may due to the transportation process, product handling, humidity, temperature, or etc. You are advised to take these issues into consideration when deciding the AQL level for your products

During inspection, all defects found are classified into 3 categories: Critical, Major and Minor. These classifications are made based on the following principles: Critical: A Defect that is likely to result in producing an unsafe condition or contravene mandatory regulation. In our normal practice, no Critical Defect is accepted; any of this kind of defect found will be subjected to an automatic rejection of inspection result. Major: A Defect that would reduce the usability of the product, or that shows an obvious appearance defect that would affect the sales of the product. Minor: A Defect that does not reduce the usability of the product, but it is still beyond the defined quality standard. Defects could be counted as critical, major or minor according to your specifications and inspection criteria.
