Yes, microwave ovens are required to obtain FCC (Federal Communications Commission) approval in the United States. The FCC is responsible for regulating various electronic devices, including microwave ovens, to ensure they comply with specific standards for electromagnetic interference (EMI) and radio frequency (RF) emissions.
The FCC's regulations aim to prevent microwave ovens from interfering with other electronic devices and communication systems. These regulations establish limits on the amount of electromagnetic radiation that can be emitted by the microwave oven during its operation.
Manufacturers must submit their microwave ovens for testing and certification to demonstrate compliance with the FCC's regulations before they can be legally sold in the United States. The FCC approval mark is typically displayed on the product or its packaging to indicate that it has passed the required tests and meets the regulatory standards.
