Brief introduction for FCC certification
FCC (Federal Communications Commission, USA Federal Communications Commission) is an independent agency American government, accountable to Congress directly. Support engineering department is responsible for thetechnical committee FCC, and equipment approval matters. According to theUSA Federal Communications regulations (CFR Part 47) regulations, all those who enter the USA electronic products are required for Electromagnetic Compatibility Certification (except for some special provisions products), known as the FCC certification.
There are three more common way in FCC certification: Certification, DoC,Verification. These three kinds of product certification procedures have great differences, different products can choose the authentication mode related regulations in FCC. The degree of decreasing strict certification. To these three kinds of authentication, the FCC committee also has the related requirement of each test chamber.
The main purpose of FCC certification
The FCC to formulate regulations are aimed at reducing the electromagnetic interference, management and control of radio frequency range, to protect the normal operation of telecommunication network, electrical products.Electromagnetic interference into the conducted interference and radiated interference. Conduction disturbance propagation through the power line, the frequency is below 30MHz, the main audio frequency interference. If the appliance products are metal shell for shielding effect, mainly for the conducted interference. The conducted interference size was measured in many electrical appliances (such as computer power) an important standard of quality. We mayhave this experience in their daily work, in the computer boot, near the TV,stereo and other electrical appliances such as not normal use, this is the effect of conduction interference. An example is the mobile phone radiation interference, when in use, the nearby computer screen will appear the obviousjitter, phone can hear the noise signal sound.

FCC certification norms applicable range of products
FCC to control products (including personal computer, CD player, radio, fax machines, photocopiers, video game machines, office machinery, electronic toys,television and microwave ovens), according to the conditions of use for A, B two categories: a class for commercial or industrial use products, products for Bclass household use. FCC products on the B regulations more stringent requirements. This is because the average home user, lack of professional and technical personnel with professional skills training; and electrical safety of the family environment is not as office environment more favorable. So the productsafety requirements on the use of home users use products than for businessindustrial environment more strict.
FCC has different specifications for different products, such as FCC Rule Part 15 is suitable for electronic instruments, digital equipment and low power transmitter;FCC Rule Part 18 is suitable for household appliances microwave ovens; FCCRule Part 22 is suitable for mobile phone; FCC Rule Part 95 is suitable for remote control toy.
FCC of the unqualified products punishment
FCC on illegal products usually impose a very severe punishment. The degree of punishment, generally enough to let the offender dissipate one's fortune, unable to stand up. So few people will commit a crime it knowingly, defy the law. FCC to the illegal product sellers punishment specific methods of operation are the following:
1, all do not accord with standard of the products shall be confiscated;
2, for each individual or organization shall impose fines of $100000 - 200000;
3, impose a amount of unqualified products gross sales double fine;
4, each violation fines of $10000 for the day.
Laboratory certification and Accreditation of FCC classification
TCB (Testing Certification Body)
NVLAB (National Voluntary Lab.)
Listed Laboratory
Three commonly used methods of FCC certification
1.Certification (ID certification / accreditation verification)
Certification is the three common methods in the most stringent FCC certification.The procedure is:
- Equipment liability direction FCC application ID
In FCC approved laboratory to complete quality testing
- equipment responsible parties prepare the relevant documents
- file data and test report submitted by the Committee of FCC
Committee to review the report and the information, if no problem, issued acertificate of accreditation
- equipment responsible party logo FCC logo and ID number on the product.
Certification is mostly applied to difficult technical wireless products, low powertransmitters such as cordless telephone, automatic door remote control, wireless remote control toy and security alarm system, Part 15 intentional emission ofradio frequency energy equipment, Part 18 of the mass of consumers to useindustrial, scientific and medical equipment, automatic conversion receiver and super regenerative receiver TV interface devices, and home computers and peripherals. It also includes special: energy-saving lamps consumer.
2.Declaration of Conformity (DoC / declaration of conformity) DoC is currently themost commonly used method of FCC certification, its characteristic is economicand rapid. The method does not need the FCC committee staff to review the test report, manufacturers may use self certification approach. But the selfcertification test report must be issued by NVLAP standard recognitionlaboratory.
FCC Class A products can be used for self authentication method, applicationprogram does not need through the FCC committee. Applicable to Verificationproducts also can use DoC authentication mode.
DoC certification process is as follows:
- equipment responsible party (usually a manufacturer or importer) present testapplication to the recognized NVLAB laboratory.
- submit product data and samples to the laboratory.
- sample tested by laboratory according to FCC regulations.
Through laboratory test, after qualified report.
