EN 55022:2010 Infor­ma­tion tech­nol­ogy equip­ment– Radio dis­tur­bance char­ac­ter­is­tics– Lim­its and meth­ods of mea­sure­ment

Scope
Inter­na­tional stan­dard EN 55022:2010 is applic­a­ble to infor­ma­tion tech­nol­ogy equip­ment (ITE). Stan­dard EN 55022:2010 defines infor­ma­tion tech­nol­ogy equip­ment as any equip­ment or device that oper­ates with a rated sup­ply volt­age not exceed­ing 600V, has a main func­tion of entry, stor­age, dis­play, retrieval, trans­mis­sion, pro­cess­ing, switch­ing, or con­trol of data and equip­ment that could be used in com­bi­na­tion with one or more ter­mi­nal ports with the main func­tion– infor­ma­tion trans­fer. Equip­ment or device, with a main func­tion of radio trans­mis­sion or recep­tion are not cov­ered by stan­dard EN 55022:2010.

Clas­si­fi­ca­tion
Inter­na­tional stan­dard EN 55022:2010 divides equip­ment, devices and appa­ra­tus it two classes:
Class B- equip­ment, device and appa­ra­tus, that are intended to be used in the domes­tic envi­ron­ment and meets EN 55022:2010 class B emis­sion require­ments;
Class A- equip­ment, device and appa­ra­tus, that do not meet the EN 55022:2010 class B emis­sion require­ments, but com­plies with EN 55022:2010 class A emis­sion require­ments;

If class A require­ments are applied, then fol­low­ing warn­ing shall be included in the instruc­tions for use:

Warn­ing

This is a class A prod­uct. In a domes­tic envi­ron­ment this prod­uct may cause radio inter­fer­ence in which case the user may be required to take ade­quate measures.


Exam­ples
PC, telecom­mu­ni­ca­tion equip­ment, office machines, data pro­cess­ing equip­ment, ITE acces­sories, portable bat­tery sup­plied devices.

Require­ments
Con­ducted emis­sion require­ments for mains ports and telecom­mu­ni­ca­tion ports must be sat­is­fied in fre­quency range 150kHz-​30MHz.

Radi­ated emis­sion require­ments must be sat­is­fied in fre­quency rage:
30MHz-​1GHz if inter­nal oscil­la­tor fre­quency is up to 108MHz
30MHz-​2GHz if inter­nal oscil­la­tor fre­quency is up to 500MHz
30MHz-​5GHz if inter­nal oscil­la­tor fre­quency is up to 1GHz
30MHz-​6GHz if inter­nal oscil­la­tor fre­quency is higher than 1GHz

EMC test­ing

RF EMC DEVEL­OP­MENT pro­vides accred­ited EMC test­ing to reach Euro­pean mar­ket. We hold a long list of Euro­pean stan­dards for such indus­tries as– house­hold, indus­trial, auto­mo­tive, med­ical, tele­com, rail­way and aero­space. Our test lab­o­ra­tory is accred­ited by Euro­pean noti­fied bod­ies accord­ing to ISO17025. Save your time by try­ing to cou­ple EMC test­ing with other tests and CE cer­ti­fi­ca­tion needs (safety, envi­ron­men­tal, energy effi­ciency, performance).


Cer­ti­fi­ca­tion

Through our part­ners, noti­fied bod­ies in Euro­pean Union, RF EMC DEVEL­OP­MENT pro­vides cer­ti­fi­ca­tion ser­vices for man­u­fac­tur­ers, retail­ers, dis­trib­u­tors and sup­pli­ers to enter EU mar­ket. We pro­vide all ser­vices to cer­tifi­cate your prod­ucts in short time span– EMC test­ing, LVD test­ing, devel­op­ment for such prod­ucts as: light­ing equip­ment, auto­mo­tive, con­sumer elec­tron­ics, indus­trial elec­tronic and machin­ery, med­ical equip­ment, telecom­mu­ni­ca­tions and wood­work­ing equip­ment etc.
