Microwave Oven Door Shield Screen is used for blocking microwave energy at the oven door while users can still see the food, using a perforated metal screen whose 1–2 mm holes are far smaller than the 12 cm wavelength. IEC 60335-2-25 is the reference cited for it on drawings, datasheets and purchase orders.
What IEC 60335-2-25 Means for Microwave Oven Door Shield Screen
The dimensions in the table below are supplied to suit IEC 60335-2-25. Where the standard sets requirements for the finished appliance, device or system, compliance testing of that assembly stays with its manufacturer; we supply the metal mesh part to the drawing and can provide material certificates and dimensional reports with the shipment.

| 25 L door | 1.5 | 2.2 | 0.4 | 42.2 | Cold-rolled steel, black |
| 32 L door | 1.6 | 2.4 | 0.5 | 40.3 | SS430 |
| Built-in combi | 1.2 | 2.0 | 0.5 | 32.6 | SS304 |
Specifying Microwave Oven Door Shield Screen Beyond the Standard
- Hole diameter & pitch: 1.2–1.6 mm holes keep leakage well under the 5 mW/cm² limit when the door is correctly sealed.
- Open area: Higher open area improves visibility; balance it against shielding margin.
- Material & finish: Black-coated cold-rolled steel for contrast; SS430 for premium doors.
When Microwave Oven Door Shield Screen Is Not the Right Choice
Not a DIY part — door repairs must be leakage-tested by qualified service technicians.
