Microwave Leakage Limits: What Does the Law Say?
Microwave ovens are powerful appliances that use electromagnetic energy to heat food quickly. However, if this energy leaks due to damage or wear, it can pose health risks such as burns or radiation exposure. That’s why strict laws exist to limit acceptable microwave leakage levels. Regulatory bodies like the FDA (in the U.S.) and standards such as AS/NZS 60335.2.25 (in Australia and New Zealand) define maximum leakage as 5 mW/cm² at 5 cm distance. These limits are designed to ensure user safety and workplace compliance. Regular testing and tagging help businesses stay within these legal thresholds and protect everyone around.

Legal Limits for Microwave Leakage
Governments around the world enforce strict regulations to control microwave radiation exposure. These legal limits ensure that appliances used in homes and workplaces operate within safe boundaries. The most widely accepted limit is 5 milliwatts per square centimeter (mW/cm²) measured at a distance of 5 centimeters from the microwave’s surface. This standard is upheld across regions like the U.S., Australia, New Zealand, and the European Union. Regular compliance checks are necessary, especially for commercial and industrial kitchens. Breaching these limits can result in legal penalties, equipment bans, or serious health hazards.

International Standards for Microwave Leakage
Microwave leakage regulations are consistent across major regions, ensuring safety and accountability. Most countries set the legal limit at 5 mW/cm² measured at 5 cm from the oven surface. These standards help protect users and require regular testing, especially in commercial settings. To Know More Click Here
- New Zealand & Australia (AS/NZS 60335.2.25:2011)
- Max leakage: 5 mW/cm² at 5 cm
- Recommended for regular testing in workplaces
- United States (FDA 21 CFR 1030.10)
- Max emission: 5 mW/cm² at 5 cm
- Must maintain this limit throughout the product’s life
- European Union (EN 60335-2-25)
- Follows international leakage limit: 5 mW/cm² at 5 cm
- Ensures user protection and manufacturer compliance

Why Compliance Matters
Microwave ovens that leak beyond legal limits can pose serious health and legal risks. Non-compliance with safety standards may lead to costly consequences for businesses, especially in regulated environments like hospitality and healthcare. Ensuring compliance not only protects people but also safeguards business operations and brand integrity. That’s why periodic testing is essential. To Know More Click Here
