How to carry out Premium Backpack Inspection?

Based on normal backpack inspection(such as promotion backpack inspection), premium backpack inspection requires larger sample size  for inspection, stricter standard for defects allowance (stricter AQLs for Major and Minor defects) and more technical requirements for backpack products.

Unless otherwise instructed, AiT uses the Single Sampling Plan Normal Level III (according to the ANSI/ASQ Z1.4 standard). This is generally the strengthened inspection requirement for products manufactured in China. It is also the most widely accepted sampling method by every industrial company for premium products.

The AQLs for premium backpack are usually AQL 0 for critical defects, AQL 1.5 for major defects and AQL 2.5 for minor defects, unless otherwise instructed.
