Hi everybody,

The C-Tick mark was a certification mark used in Australia and New Zealand to indicate that a particular electronic or electrical product complied with the applicable Australian and New Zealand electromagnetic compatibility (EMC) standards. The C-Tick mark demonstrated that the product did not emit excessive electromagnetic interference (EMI) and could function as intended without causing interference to other electronic devices.

Background and Purpose
The C-Tick mark was administered by the Australian Communications and Media Authority (ACMA) and was a legal requirement for a wide range of electronic and electrical products sold in Australia and New Zealand. The primary purpose of the C-Tick mark was to ensure that products met the necessary EMC requirements to protect the radiofrequency spectrum and ensure the proper functioning of communication networks and equipment.

Scope and Applicability
The C-Tick mark applied to various products, including + information technology equipment, + telecommunications equipment, + electrical appliances, + lighting products, and + industrial machinery. Manufacturers or importers of these products were required to ensure compliance with the relevant EMC standards and to register with the ACMA before affixing the C-Tick mark to their products.

Compliance Process
The compliance process for obtaining the C-Tick mark involved several steps:

Assessment: Manufacturers needed to assess their products against the applicable EMC standards. This usually involved testing the product in an accredited laboratory to measure its electromagnetic emissions and immunity.

Documentation: Manufacturers were required to maintain a compliance folder containing evidence of compliance, such as test reports, technical documentation, and a declaration of conformity.

Registration: Manufacturers or importers had to register with the ACMA and provide details about the product and its compliance.

Labeling: Once compliance was established, the product could be labeled with the C-Tick mark, along with the supplier's identification number.

Transition to the RCM Mark
In 2013, the C-Tick mark was phased out and replaced by the Regulatory Compliance Mark (RCM) as part of a harmonization effort to simplify the compliance marking for products subject to + electrical safety, + electromagnetic compatibility, and other regulatory requirements in Australia and New Zealand. The RCM mark now serves as a single compliance mark indicating that a product meets all applicable regulatory requirements, including EMC, electrical safety, and telecommunications standards.

In summary, the C-Tick mark was a certification mark used in Australia and New Zealand to indicate compliance with EMC standards for electronic and electrical products. It has been replaced by the RCM mark, which consolidates various compliance requirements under a single mark, simplifying the process for manufacturers and ensuring that products meet the necessary safety and performance standards.
