Singapore Radio Type Approval (IMDA) is a technical specification and compliance process for radio communications equipment used in the country. The process is managed by the Infocomm Media Development Authority (IMDA), which is the regulatory body for the telecommunications and media industries in Singapore. IMDA provides guidelines for radio equipment type approval, which manufacturers must follow in order to sell their products in the country. The type approval process includes tests to ensure that the equipment meets international standards for safety, electromagnetic compatibility, and radiofrequency emissions. IMDA also issues licences for the import, sale, and use of radio communications equipment in Singapore. Manufacturers must obtain a licence from IMDA before their products can be sold in the country. IMDA maintains a list of approved radio equipment, which is available on its website.
