Elec­tro­mag­netic com­pat­i­bil­ity test­ing in EMC lab EN 55024, CISPR 24

EN 55024:2010 Infor­ma­tion tech­nol­ogy equip­ment– Immu­nity char­ac­ter­is­tics– Lim­its and meth­ods of mea­sure­ment (CISPR 24:2010)

Scope
Inter­na­tional stan­dard EN 55024:2010 is applic­a­ble to infor­ma­tion tech­nol­ogy equip­ment (ITE). Stan­dard EN 55024:2010 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 55024:2010.

Clas­si­fi­ca­tion
Inter­na­tional stan­dard EN 55024:2010 have no spe­cific over­all clas­si­fi­ca­tion of equip­ment.

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

Per­for­mance cri­te­ria

Cri­te­rion A
Dur­ing and after the test­ing the EUT shall con­tinue to oper­ate as intended with­out oper­a­tor inter­ven­tion. No degra­da­tion of per­for­mance or loss of func­tion is allowed below a min­i­mum per­for­mance level spec­i­fied by the man­u­fac­turer when the EUT is used as intended.

Cri­te­rion B
Dur­ing the test­ing, degra­da­tion of per­for­mance is allowed, but no change of oper­at­ing state or stored data is allowed to per­sist after the test. After the test­ing, the EUT shall oper­ate as intended with­out oper­a­tor inter­ven­tion and with­out degra­da­tion. No degra­da­tion of per­for­mance or loss of func­tion is allowed, after the appli­ca­tion of the phe­nom­ena below a per­for­mance level spec­i­fied by the man­u­fac­turer, when the EUT is used as intended.

Cri­te­rion C
Dur­ing and after test­ing, a tem­po­rary loss of func­tion is allowed, but func­tions shall be self-​recoverable, or can be restored by the oper­a­tion of the con­trols and/​or turn­ing off /​on the power of the EUT, fol­low­ing the man­u­fac­turer instructions.

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.
