UL

Initial Production Inspection (IPI)

• When the UL certified product is first produced.
• This test is performed as long as it is a new factory or a new product category in the original plant (IPI is not required in some special cases).
• Confirm that UL certified product manufacturers produce products that meet the requirements of the Follow-Up Services Procedure.
• It is very similar to other tests except that the inspection date is determined by the customer and UL.
• If the product complies with the requirements of the subsequent inspection service procedure, the UL factory inspector will allow subsequent production to continue to use the UL Mark/Indicator/Label.

Before the factory inspection, the factory needs to prepare the following documents for inspection:

1. Company organization chart
2. Quality Control Flow Chart
3. Production flow chart
4. Product change flow chart or file
5. QC personnel and key position personnel training records
6. Incoming inspection related files (such as standards, work instructions, etc.)
7. Process (production) inspection related files
8. Shipment inspection related documents
9. Equipment management related documents (such as calibration memory, equipment account, etc.)
10. Basic production equipment (such as high pressure meter, etc.)
11. Non-conforming product control
