Random Inspections: by default we use AQL system, but for long term contracts we can assimilate other methods. We offer the following three (3) phase inspections per order/style/shipment:
Pre-production: we scrutinize pre-production samples (or factory test runs products) and discuss our findings with the factory at a pre-production meeting. During that meeting the factory has to persuade our inspectors that they can control and avoid the defects found in the samples by implementing changes in their production methods and/or put additional specific in-line quality supervisors.
In-line Inspections: at least twice during the course of the production, our inspectors randomly inspect the various stages of production as well as finishing and packing based on AQL method and report the findings.
Final Inspection: based on AQL system, our inspectors check packed goods and verify all aspects of quality before shipment. Packing conditions, visual aspect, detection of defects, functional inspection (operate the moving/closing parts), measurement control, touch and smell.
For random inspections we use AQL system, but we can adjust to your standards.
Acceptable Quality Level [AQL]
As MIL-STD-105E is based on random sampling, therefore a few defects are considered acceptable. The AQL is the maximum defect rate that, for purposes of sampling inspection, can be considered satisfactory as a process average. Different AQL may be designated for different defects such as critical, major and minor defects. The AQL should be agreed upon between buyer and supplier before the start of production.
Defect Classification
The client defines the AQL and the maximum number of defective goods allowed in the sample size. Defects detected during visual inspection are usually classified within three (3) categories: “Critical”; “Major”; and “Minor”.
- Critical: likely to result in unsafe condition or contravene mandatory regulation or reject by import customs.
- Major: reduces the usability/function and/or sale of the product or is an obvious appearance defect
- Minor: doesn’t reduce the usability/function of the product, but is a defect beyond the defined quality standard more or less reduces the sale of the products.
Clients can specify what points are minor, major or critical in a defect classification check list together with the inspection criteria and product specification.
100% Inspections
We keep one or more inspectors in factory at all times, doing both in-line and final inspections.
Our staff will do 100% visual final inspection (every piece will be visually inspected by our crew before packing) and 10% measurements check on goods before packing.
This form of inspection is commonly used when dealing with new factories, factories that have a “poor record” or when the buyer does not feel confident about a factory’s quality level.
