FCC established in 1934 as an independent body of the US government. The FCC coordinates domestic and international communications by controlling radio, television, telecommunications, satellites and cables. Many radio applications, communications products and digital products to enter the US market, require FCC approval - FCC certification. The FCC committee investigates and studies the various stages of product safety to find the best way to solve the problem, while the FCC also includes radio equipment, aircraft testing, etc. [1].
 
       In the United States, the Federal Communications Commission (FCC) is responsible for authorizing and managing radio frequency transmission devices and equipment other than those used by the federal government. For this reason, under the guidance of the National Environmental Act, the FCC is also responsible for the adverse effects of the equipment and equipment on which it is approved, and the environmental factors that must be evaluated are those that are exposed to the transmitter Of the RF EMF.

On August 1, 1996, the FCC adopted a new specification for assessing exposure to radio frequency fields. Prior to this, the FCC relied on the American National Standards Organization to achieve this goal. The newly adopted specification for maximum allowable exposure is based on ANSI's 1992 revision standard (ANSI / IEEE C95.1-1992). In 1992, this standard was developed by a committee of the IEEE, and the establishment of this specification also adopted the exposure standards recommended by the National Radiation Protection and Survey Advisory Agency in 1986. The FCC adopted the NCRP standard for electrical and magnetic fields, power density and time averages. The NCRP limits are consistent with those included in ANSI / IEEE C95.1-1992, except that the power density limit exceeds 1500 MHz and some of the low frequency and time averages of the magnetic field. MPE limit covers the bandwidth is 300KHz to 100GHz. Including two exposure levels, one is "occupational / control" exposure, another more stringent level is "normal population / uncontrolled" exposure. Restrictions on the limitations (partial body) absorption are adopted for exposure to portable and mobile devices. These recent limitations are expressed in terms of the specific absorptivity concept and are based on the 1992 ANSI / IEEE and NCRP recommendations. FCC operations are usually supported by the United States responsible for the protection of public health agencies, including the US Environmental Protection Agency, the US Food and Drug Administration, the National Occupational Safety and Health Organization and the Occupational Safety and Health Administration, which will be used by the FCC Application and refinement to provide details.

According to the relevant part of the Federal Communications Act (CFR 47), all electronic products entering the United States are required for electromagnetic compatibility certification (except for some of the provisions of the special provisions of the product), of which there are three common certification methods: Certification, DoC, Verification. The three products of the certification methods and procedures are quite different, different products can be selected in the FCC certification in the relevant provisions. The degree of strictness of its certification decreased. In response to these three certifications, the FCC Committee also has requirements for each laboratory.
 
      At present, the United States has for several years to become China's second largest trading partner, Sino-US trade volume was increasing year by year, so the US exports can not be underestimated. US product technology standards, import regulations rigorous called the world's first, understand the US market access rules will help China's products to further open the US market. Federal Communications Commission (FCC) - manages the import and use of radio frequency devices, including computers, fax machines, electronic devices, radio receiving and transmitting equipment, radio remote control toys, telephones, personal computers and other products that may harm personal safety. If these products are to be exported to the United States, they must be inspected and approved by a government-authorized laboratory in accordance with FCC technical standards. Importers and cus
