Electromagnetic Compatibility (EMC) Testing

All electrical and electronic products that manufacturers plan to sell in the United States must comply and meet relevant RF and EMC requirements under the&nbsp;Federal Communications Commission (FCC).

FCC&nbsp;testing and authorization involves two approval procedures - &#39;Certification&#39;&nbsp;and &#39;Supplier&rsquo;s Declaration of Conformity (SDoC)&#39;.

The approval procedure required to be used is specified in the applicable&nbsp;FCC&nbsp;rule part(s) that apply to the radio frequency functions of a device or an end product. In general, except when otherwise stated in a rule, intentional radiators(transmitters) arerequired to be approved using the certification procedure,and unintentional radiators (e.g.digital circuitry) are approved using the&nbsp;SDoC&nbsp;procedure.

STC&rsquo;s technical competence meets&nbsp;FCC&nbsp;requirements for various scopes of accreditation for testing performed in support of&nbsp;SDoC&nbsp;and Certification.

  FCC Recognized Accredited Scope   	 Unintentional Radiators&nbsp;(FCC Part15 Subpart B) 	 Intentional Radiators&nbsp;(FCC Part 15 Subpart C) 	 U-NII without DFS Intentional Radiators&nbsp;(FCC Part 15 Subpart E) 	 UWB Intentional Radiators&nbsp;(FCC Part 15 Subpart F) 	 White Space Device Intentional Radiators&nbsp;(FCC Part 15 Subpart H) 	 Industrial, Scientific, and Medical Equipment&nbsp;(FCC Part 18)  If you have any further question, please feel free contact us at&nbsp; enquiry@stc.group &nbsp;or visit our website:&nbsp; https://www.stc.group/en/contact
