The product inspections include
- Agreements with the customers
- Laboratory and testing equipment
- In-house control
- Inspection (testing) of anodized products
- Marking and labelling
The plant inspections include
- Processes - mostly recommended practices
The inspector may test samples of anodized products at the plant or take them back to his testing institute for testing.
