AS/NZS 3112 Plug and Socket-Outlet Test Solution

About AS/NZS 3112

AS/NZS 3112 is an electrical safety standard jointly developed by Australia (AS) and New Zealand (NZS), fully titled AS/NZS 3112: 2017 Approval and test specification-Plugs and socket-Outlets. The standard specifies the safety design, performance criteria, and testing requirements for plugs and socket-outlets in household and similar applications, aiming to ensure the safe use of electrical equipment and prevent risks such as electric shock and fire. It applies to plugs and socket-outlets for household and similar purposes with not exceeding 500V and a rated current not exceeding 32 A.

 

As a fundamental standard for electrical safety in the Australia-New Zealand region, AS/NZS 3112 ensures user safety in electricity use by strictly regulating the design, production, and testing processes of plugs and socket-outlets. For manufacturers, importers, and consumers, understanding this standard helps ensure product compliance or select safe and reliable electrical equipment. The following are the testing items covered by this standard.
