ANSI/ASQ Z1.4-2008 (AQL) Standard
At TradeAider, we use the globally trusted ANSI/ASQ Z1.4-2008 (AQL) Single Sampling Plan for all inspections. This standard, aligned with ISO 2859-1 and equivalents like BS6001, ABC105, ANSI/ASQ Z1.4, NFX 06-022, ISO2859-1 and DIN 40080, ensures consistent, reliable quality checks. This method is widely used to determine whether to accept a production lot without checking every single unit, and it's special Inspection Level will be applied for safety, reliability, performance or other special tests if whereas applicable. The method 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. Our default Acceptable Quality Level is Level II.
