What national standards must EPSEMC meet?

In China, EPS products need to meet a series of mandatory (GB) and recommended (GB/T) EMC standards, depending on their application (e.g., civil, industrial, medical). The main standards include:

1. Emission standards: GB4824 "Limits and methods of measurement of radio frequency interference characteristics of industrial, scientific and medical equipment" is a common standard, specifying conducted and radiated emission limits (divided into Class A/B environments). GB/T9254 (information technology equipment) may also be referenced.

2. Immunity standards: GB/T17626 series (equivalent to IEC61000-4 series), typically including electrostatic discharge (.2), radiated immunity (.3), burst immunity (.4), surge immunity (.5), conducted immunity (.6), power frequency magnetic field (.8), voltage dips (.11/.34), etc.

3. Product-specific standards: GB17945 "Fire emergency lighting and evacuation guidance systems" has specific EMC requirements for fire-fighting EPS. Enterprises need to select applicable standards and pass type tests by third-party testing institutions based on product classification and claims.
