CB Certification Testing Standards for Sockets

The CB standards for sockets and plugs are primarily based on a series of standards developed by the International Electrotechnical Commission (IEC), specifically IEC 60309-1 and IEC 60309-2. These standards apply to industrial plugs, sockets, and couplers, specifying general requirements and ensuring the interchangeability of pin and sleeve dimensions. This guarantees compatibility and safe usage of industrial plugs and sockets from different manufacturers.

1. IEC 60364-5-53

This standard addresses the selection and installation of electrical equipment in building electrical installations. It covers requirements for insULation, switching, and control, ensuring the safe and reliable operation of plugs and sockets in building electrical systems.

2. IEC 60320-1

This standard specifies general requirements for appliance couplers used in household and similar general-purpose devices. It defines basic performance and safety criteria for household plugs and sockets to meet daily safety demands.

3. IEC 60884-1 and Related Parts

- IEC 60884-1 provides general requirements for plugs and socket-outlets for household and similar purposes. It includes tests for marking and dimensional verification, electric shock protection, grounding measures, and more, ensuring the safety and reliability of plugs and sockets from multiple perspectives.

- IEC 60884-2 covers specific requirements for various types of household plugs and sockets, such as:

- Converters

- Fused plugs

- Appliance sockets

- Interlocked and non-interlocked socket-outlets for fixed installations

- Plug and socket systems for safety extra-low voltage (SELV)

- Extension cords

- Portable socket-outlet devices

4. IEC 60906-1, IEC 60906-2, and IEC 60906-3

These standards specify requirements for different types of IEC-standard plugs and sockets for household and similar appliances, including:

- AC plugs and sockets rated at 16A 250V, 15A 125V, and 20A 125V

- AC and DC plugs and sockets rated at 16A for 6V, 12V, 24V, and 48V (safety extra-low voltage).
