Product Overview
As professional manufacturers of Microwave Oven Door Endurance Tester, we have developed a device specifically to assess the durability of microwave oven door systems. In line with IEC 60335-2-25 clause 18, this tester simulates the normal opening and closing of microwave oven doors to verify the wear resistance of key components: hinges, microwave seals, and associated structural parts. It ensures that microwave ovens meet safety and longevity requirements during long-term use, making it an essential tool for home appliance manufacturers and quality inspection institutions.

Product Features
Realistic Use Simulation
The tester precisely replicates the normal opening and closing actions of microwave oven doors, with an adjustable angle range of 0°-140° (matching most microwave oven designs). The 6 cycles per minute operation rate aligns with average user usage frequency, ensuring test results reflect real-world durability.
Intelligent Safety Monitoring
An integrated electronic circuit with a 10A plug monitors the sample’s power status (for samples ≤2000W). If the microwave oven loses power during testing (indicating a potential door-related fault), the machine stops automatically, and the counter locks the test count while triggering a warning. This prevents invalid tests and protects the sample from damage.
Durable & Flexible Structure
The test frame is made of industrial molding aluminum, which offers high rigidity and resistance to deformation, ensuring stable operation over long test cycles. It supports both horizontal and vertical sample installation, compatible with various microwave oven models (e.g., countertop, built-in).
Application
This tester is indispensable for:
Microwave oven manufacturers: Conducting pre-shipment quality checks and R&D testing to optimize door hinge and seal designs;
Quality inspection labs: Verifying compliance with IEC 60335-2-25 standards for product certification;
Third-party certification bodies: Assessing the durability of microwave ovens for market access (e.g., CE, GS certification);
After-sales service centers: Diagnosing door system reliability issues for faulty products.
FAQ
What is the maximum microwave oven power this tester can handle?
The standard configuration supports samples with power below 2000W (via a 10A plug). For higher-power microwave ovens (e.g., 2500W), we can provide a customized 16A plug and matching circuit.
How does the counter work?
It is a 6-digit electronic predetermining pulse counter. You set the desired number of test cycles (e.g., 10,000 cycles) before starting; the machine stops automatically once the counter reaches the set value, and the count is retained for data recording.
Can it test microwave ovens of different sizes?
Yes. The adjustable test frame and support for horizontal/vertical installation allow compatibility with most microwave oven sizes, from small countertop models to large built-in units.
