A / c-tick is an authentication mark issued by Australian Communications Authority (ACA) for communication equipment. C-tick is the certification for electromagnetic compatibility of electronic products in Australia, which is a compulsory certification of import and export customs. All electronic products entering Australia must have this certificate. Communication products can apply for a-tick certification, while electronic products can apply for c-tick certification.

Manufacturers and importers must follow the next steps to use a-tick:

1. Products are tested according to acaq technical standard

2. Register with ACA to use a / c-tick

3. Fill in the declaration of conformity form and keep it together with the product conformity record

4. Label with a / c-tick on communication products or equipment

5. A-tick sold to consumers is only applicable to communication products, and most electronic products apply for c-tick. However, if electronic products apply for a-tick, there is no need to apply for c-tick.

Since November 2001, Australian / New Zealand EMI has applied for merger; If the products are to be sold in these two countries, the following documents must be prepared for random inspection by ACA (Australian Communications Authority) or the Ministry of economic development (New Zealand) authorities at any time before marketing:

1. The test report must be approved and issued by Nata or the certification body mutually agreed with Nata, such as nvlap or A2LA recognized laboratory, otherwise the sample delivery probability is very high.

2. "Application to use the c-tick mark" form - must be signed by an Australian / New Zealand company or importer.

3. "Supplier's declaration of conformity" form - must be signed by an Australian and New Zealand company or importer. The manufacturer responsible for signing is responsible for ensuring that the products sold still comply with EMI regulations.

4. Original design drawings and specifications (such as circuit diagram, block diagram, user's manual, service manual, etc.).

5. Describe the production inspection procedure to ensure the maintenance of EMI characteristics.

6. Description of any changes that may affect EMI and necessary test records.

Certification period: 1-2 weeks

The information of Australian supplier must be marked beside the c-tick mark according to the regulations, so that ACA can effectively trace back to the supplier responsible for EMC when sampling products in the market. The identification of information includes four aspects

1. Registered name and address of Australian supplier

2. Australian company number

3. Number issued by ACA to Australian supplier

4. The Australian registered trademark used in the Australian market

The c-tick sequence label radio communication equipment or special electrical and electronic equipment must meet the relevant label notice requirements, otherwise they cannot be sold or supplied to Australia. The c-tick sequence label is a sequence label, which is applicable to the material items covered by the following label notice

1. Radio communication (sequence label with transmission) bulletin 2001 brief description of compliance with EMC adjusted arrangements

2. Radio equipment (sequence label) Notice No. 1 1996 to show briefly the arrangement of radio communication subject to adjustment

3. Radio communication (sequence label - electromagnetic radiation) Notice 2003 brief description subject to EMR adjustment arrangement

Under the EMC adjustment arrangement, the product must be labeled in sequence before it is supplied to Australia. It is also a sequential label for non radio communication products that must comply with the electromagnetic radiation (EMR) rules. For telecom products, EMR is covered by a-tick sequence label. The sequence label on c-tick must have the supplier information that can identify the supplier. This information may take the supplier code issued by ACA, the Australian company number or other forms detailed in the relevant label notice. More information about the use of c-tick mark can be obtained on the ACA website.

Australia's EMC system divides products into three levels. Before selling Level 2 and level 3 products, suppliers must register with ACA and apply for c-tick mark.

Level 1 products refer to products with low interference radiation to equipment using wireless spectrum, such as manual switch, simple relay, unidirectional squirrel cage inductive motor, resistor, etc. For level 1 products, the supplier must sign the conformity statement and provide the product description. Level 1 products can voluntarily apply for c-tick mark, but after choosing to use the mark, the supplier should provide a statement of compliance and product description, as well as a record of compliance to prove that the products described in the statement have met the relevant EMC standards. The test site is not required, and internal test is allowed.

Level 2 products refer to products with high interference radiation to equipment using wireless spectrum, such as switching power supply, electric welding machine, dimmer, most household appliances, etc. In addition to signing the conformity statement and providing the product description, the supplier should also provide the test report according to the relevant standards. If there is no relevant standard, the supplier should provide the technical structure test location is not required, and the internal test is allowed.

Level 3 products refer to the products with extremely high interference radiation to the equipment using wireless spectrum, that is, the 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 divided into Level 2 products. In addition to signing the conformity statement and providing the product description, the supplier should also provide the test report issued by the recognized testing agency. At the same time, the quality management system certificate issued by QSM certification body should be issued.
