IEC 60397: Industrial Microwave Heating Equipment — From Food Processing to Ceramic Sintering

Microwave Heating Is Not Just “Reheating Food” — Industrial Microwave Equipment Reaches 100 kW

IEC 60397:1994 specifies industrial microwave heating equipment testing. While domestic microwaves operate at ~1kW, industrial units exceed 100kW for rubber vulcanization, ceramic sintering, food drying, and medical waste sterilization. Frequencies: 915MHz (industrial) and 2,450MHz (domestic/medical) — 915MHz offers ~3× deeper penetration for large-volume materials.

TNLab — Industrial and domestic microwaves share the same physics, but power and penetration depth considerations are entirely different.
