In Australia, the EMC requirements for electrical products are monitored by the ACA (Australian Communications Authority). In addition to the Australian and New Zealand standards (AS / NZS), the ACA recognized 103 other standards last year. These standards include EN (European Norm), IEC (International Electrotechical Commission), and CISPR (International Special Committee on Radio Interference) ).

限制 In order to limit the impact of electromagnetic interference, Australia has implemented mandatory electromagnetic interference (EMI) requirements for all products within the scope of the standard from January 1, 1999. Some EMC experimental projects must also comply with mandatory requirements, which are: conducted interference, intermittent interference (click), radio frequency radiation interference; other EMC test projects do not make mandatory requirements, such as anti-interference, electrostatic discharge (ESD), harmonic Waves, voltage flicker, etc. After inspection, the product meets the relevant standards and can be labeled with the C-Tick mark. Any company or individual who wants to use this mark must apply to the competent government department, and it can only be used after obtaining written approval, and the height of the mark is not less than 3 mm.

Labeling requirements

The C-Tick mark must be marked with the information of Australian suppliers in order to allow ACA to effectively trace back to the supplier responsible for the EMC of the product when sampling products on the market. The identification of the information includes four aspects:

1. Australian supplier's registered name and address;

2. Australian Company Number

3. Number issued by ACA to Australian supplier;

4. Australian registered trademark used in the Australian market.

EMC Product Grade

The Australian EMC system divides products into three levels. Before selling level two and level three products, suppliers must register with the ACA and apply for the C-Tick logo.

Class 1 products refer to products with low interference radiation to equipment using wireless spectrum, such as manual switches, simple relays, unidirectional squirrel-cage induction motors, resistors, etc. For Level 1 products, the supplier must sign a declaration of conformity and provide a product description. Level 1 products can voluntarily apply for the C-Tick mark, but after choosing to use the mark, the supplier must provide a declaration of conformity and a description of the product along with a record of conformity to prove that the product described in the declaration has been Meets relevant EMC standards. The test site is not required and internal testing is allowed.

Class 2 products refer to products that have high interference radiation to equipment using wireless spectrum, such as switching power supplies, welding machines, dimmers, and most household appliances. In addition to signing the declaration of conformity and providing a product description, the supplier must also provide a test report according to relevant standards. If there is no relevant standard, it is necessary to provide technical structure documents, and the test site does not require it. Internal testing is allowed.
