We can help you gain access to US markets through our accredited testing services.

EMC Testing

RN Electronics is recognised as a Conformity Assessment Body (CAB) by the Federal Communications Commission (FCC), and we are designated to perform compliance testing on equipment subject to Suppliers Declaration of Conformity (SDoC) under Parts 15B and 18 of the Commission's Rules.

There are two main parts of the Code of Federal Regulations (CFR) that cover EMC:
FCC Part 15B – Radio frequency devices (non-intentional radiators).
FCC Part 18 – Industrial, scientific and medical equipment.

Radio Testing

As an FCC accredited testing laboratory for the US market, RN Electronics can perform unlicensed radio testing to various parts of 15C, along with testing to certain licensed rule parts. We can also provide certification services in order to achieve FCC grants and listing on the FCC’s website for Radio equipment. RN Electronics FCC scope of accreditation can be viewed here. FCC 47 CFR Part 15 also covers devices which are intentional radiators in subpart 15C.

Electrical equipment marketed in the USA requires authorisation. There are two routes available to show the evidence required according to the risk of interference that the type of equipment possesses:

Suppliers Declaration of Conformity (SDoC)

Unintentional radiators I.e. that connect with PC's or television systems, CB radios, digi-boxes, and other digital devices considered to be medium risk. The product is tested at an accredited facility and similar to in Europe the manufacture draws up a Declaration to accompany the product and its technical file.


Intentional radiators I.e. RF transmitters, radar detectors and certain other high-risk devices. The product is tested at a listed facility and the technical file reviewed by an independent body before a certificate is granted and details listed on the FCC website.
