Electrical and electronic products into Australia, in addition to the safety labeling, should also have EMC mark that c-tick mark. Purpose is to protect the resources of radio communication frequency band, which provides the implementation of the system is somewhat similar to the European EMC directive, therefore, can be provided by the manufacturer / importer to self-declaration. However, C-tick mark in the application, it must be tested according to the relevant CISPR standards. And be endorsed by the Australian importer & reports. Australia ACA (Australian Commication Authority) to accept all, issuing registration number.
　　Australia, electrical products, EMC requirements by the ACA (Australin Communications Authority) monitoring. In addition to the standard used in Australia and New Zealand Standard (AS / NZS) outside, ACA2002 recognized 103 years and other standards, these standards include EN, IEC and CISPR.
　　In order to limit the influence of electromagnetic interference, Australia from January 1999 onwards, all within the limits prescribed in the standard product of electromagnetic interference (EMI) mandatory. Some experimental projects must also comply with EMC mandatory requirements, they are: conduction disturbances, intermittent interference (the click), radiation interference. The remaining EMC project without mandatory. Product testing with the relevant standards in order to paste the C-Tick mark. Any company or individual to use this flag must make an application to the competent government departments to obtain written approval before use, and mark the height of not less than 3 mm.

C-Tick mark next to be marked according to the provisions Australian suppliers of information to ACA sampling products on the market can be effectively traced back to EMC is responsible for the product supplier. The identification information includes four aspects:
1. Australian suppliers registered name and address.
2. Australian Company Number (Australian Company Number)
3. Issued by the ACA Australian suppliers of numbers.
4. Products on the market in Australia using Australian registered trademark.

　　Australian EMC system is divided into three levels, vendors in the sales level two, level three products, you must register in the ACA, apply for C-Tick mark.
　　Level of a product is the use of wireless devices interfering with lower radiation spectrum of products, such as manual switches, relays simple, one-way squirrel-cage induction motors, resistors and so on. On the level of a product, the supplier must provide signed declaration of conformity and product description sheet. Level of a product may voluntarily apply for C-Tick mark, but vendors choose to use the mark, declaration of conformity and in the provision of products described in the book, while also providing compliance records to prove that statement as described in the product has been comply with the relevant EMC standards. Test site is not required, allowing the internal testing.
　　Level two products is the use of wireless devices interfering with higher radiation spectrum of products, such as switching power supplies, welding, dimmers, most household appliances. In addition to suppliers declaration of conformity must sign and deliver products described in the book, but also to provide the relevant standard test report, if there is no standard, you will need to provide technical construction file, test site is not required, allowing the internal testing.
　　Level 3 product is the use of wireless devices interfering with high radiation spectrum of products, ie products covered CISPR11 and CISPR22. Currently, the communication terminal products still is contained within this range, but from November 7, 2003, the end product will be divided into level two products. In addition to suppliers declaration of conformity must sign and deliver products described in the book, but also to provide by accredited test report issued by the agency. But also issued by the certification body QSM Quality Management System Certificate.
