A/C-Tick is a certification mark issued by the Australian Communications Authority (ACA) for communication equipment.

Manufacturers and importers must follow the steps below to use the A-Tick:

1. The product performs ACAQ technical standard test

2. Register with ACA to use A/C-Tick

3. Fill out the "Declaration of Conformity Form" and keep it together with the product compliance record

4. A label with the A/C-Tick logo on the communication product or equipment

5. A-Tick sold to consumers is only applicable to communication products. Most electronic products are to apply for C-Tick. However, if electronic products apply for A-Tick, there is no need to apply for C-Tick.

Since November 2001, EMI from Australia/New Zealand has applied for merger; if the product is to be sold in these two countries, the following documents must be prepared before marketing, in preparation for ACA (Australian Communications Authority) or New Zealand (Ministry of Economic Development) ) The authorities will conduct random inspections at any time:

1. The test report - it must be issued by NATA or a certification body mutually assigned with NATA, such as a laboratory accredited by NVLAP or A2LA to be valid, otherwise the probability of sending samples for testing is very high.

2. "Application to use the C-tick Mark" Form - must be signed by the Australian/New Zealand company or importer.

3. "Supplier's Declaration of Conformity" Form - must be signed by the Australian/New Zealand company or importer. The manufacturer responsible for the signature is responsible for ensuring that the products sold still comply with the EMI regulations.

5. Describe the production inspection procedures during manufacture to ensure the maintenance of EMI characteristics.
