Example: Documents, marking or components which are not complying with the safety standard or with the established requirements or sampling not among the required quantity of finished products.

TAP = Total Acceptable Product.
AQL = Acceptable Quality Limit/ Level.

AQL: Acceptable quality level is the Allowable percent of defectives in a Sample for an Inspection.

Five Parts of Acceptance Sampling System:

  • Lot Size
  • Sample Size
  • Acceptable Quality Level
  • Accept Number
  • Reject Number

Three Plan of Acceptance Sampling System:

  • Normal or Single Sampling Plan
  • Double Sampling Plan
  • Multi Sampling Plan

When to use a quality control inspection?

1. Initial or Pre Production Inspection (IPI or PPI):
The Initial Production Inspection checks the materials or components stored by the manufacturer to produce your order. We also inspect the initial production run.

2. During Production Inspection (DPI or DUPRO):
The During Production Inspection checks semi-finished or finished goods and takes place when a minimum 40% of your order has been produced.

3. Final Random Inspection (FRI) or Pre-Shipment Inspection (PSI):
The Final Random Inspection, or Pre-Shipment Inspection (PSI), checks finished products when at least 80% of your order has been export-packed.

4. Container Loading Supervision (LS):
Container Loading Supervision ensures that your order is completed and safely loaded in a container before shipment.
