Thailand's Standards Association Enforces MOK 1955-2551 to Prevent Light Bulbs from Disrupting Electronics

Key summary

The Thailand Standards Association (TSA) enforces MOK 1955-2551, a mandatory standard for lighting equipment that limits radio frequency interference. This regulation ensures light bulbs and similar devices do not emit electromagnetic waves that disrupt television signals, Wi-Fi, or medical equipment. Products must pass laboratory tests in anechoic chambers to verify they meet emission limits for conducted and radiated disturbances before receiving the mandatory MOK mark, which includes a QR code for verification.
