basic introduction
In Australia, EMC requirements for electrical products are monitored by the ACA (Australin Communications Authority). Standards used In addition to the Australian and New Zealand Standards (AS/NZS), ACA 2002 recognized 103 other standards, including EN, IEC and CISPR.
In order to limit the impact of electromagnetic interference, Australia has implemented electromagnetic interference (EMI) mandatory requirements for all products within the scope of the standard since January 1999. Some EMC experimental items must also meet the mandatory requirements, they are: conducted interference, intermittent interference (click sound), radiated interference. Other EMC projects are not mandatory. The product can only be affixed with the C-Tick logo after it has been inspected and meets the relevant standards. Any company or individual who wants to use this logo must apply to the competent government department and obtain written approval before using it, and the height of the logo shall not be less than 3 mm.
Information ID
The information of the Australian supplier must be marked next to the C-Tick mark according to regulations, so that ACA can effectively trace back to the supplier responsible for the EMC of the product when sampling the product in the market. The identification of information includes four aspects:
1. The registered name and address of the Australian supplier.
2. Australian Company Number
3. A number issued by the ACA to Australian suppliers.
4. Australian registered trademarks for products used in the Australian market.
Product division
Australia's EMC system divides products into three levels. Suppliers must register with ACA and apply for the use of the C-Tick mark before selling level two and level three products.
Level one product
Level 1 products refer to products with low interference radiation to equipment using the wireless spectrum, such as manual switches, simple relays, one-way 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 the supplier chooses to use the mark, he/she must provide the conformity declaration and the product description, and also provide the conformity record to prove that the product described in the declaration has been Complies with the relevant EMC standards. Testing location is not required, internal testing is allowed.
Level 2 product
Level 2 products refer to products with high interference radiation to equipment using the wireless spectrum, such as switching power supplies, electric welding machines, dimmers, and most household appliances. In addition to signing the declaration of conformity and providing product descriptions, suppliers must also provide test reports according to relevant standards. If there are no relevant standards, they need to provide technical structure documents. The test site is not required, and internal testing is allowed.
Level three products
Level 3 products refer to products with extremely high interference radiation to equipment using the wireless spectrum, that is, products covered by CISPR11 and CISPR22. At present, communication terminal products are still included in this scope, but from November 7, 2003, terminal products will be classified into level two products. In addition to signing the declaration of conformity and providing the product description, the supplier must also provide a test report issued by an accredited testing agency. At the same time, a quality management system certificate issued by the QSM certification body should be issued.
