How to Audit a Commercial Water Boiler OEM Factory: Certification, Inspection and Contract Terms
A water boiler OEM factory audit should verify business licenses, production scope, quality management, incoming inspection, welding or assembly, water tests, electrical safety, aging tests, packaging drop tests, spare-part capability and after-sales response. Branding, nameplates, manuals and packaging must match target-market requirements.

Procurement, Installation and Compliance Points
Verify Certificate Coverage
Certificate product names, models and intended use must cover the ordered boiler and cannot be substituted by similar models.
Audit Along the Production Flow
Review records and现场 conditions from incoming materials, fabrication, assembly and inspection to packaging.
Perform Prototype and Batch Inspection
After prototype approval, batch shipments still require sampling for specifications, appearance, safety and packaging.
Lock After-sales and Parts
Include heating elements, thermostats, taps, float valves, seals and panel supply in the contract.
