Equiv­a­lent: CISPR 142:2015 Elec­tro­mag­netic com­pat­i­bil­ity — Require­ments for house­hold appli­ances, elec­tric tools and sim­i­lar appa­ra­tus — Part 2: Immu­nity — Prod­uct fam­ily stan­dard

Replace: EN 550142:1997 +A1 +A2 +AC Elec­tro­mag­netic com­pat­i­bil­ity — Require­ments for house­hold appli­ances, elec­tric tools and sim­i­lar appa­ra­tus — Part 2: Immu­nity — Prod­uct fam­ily stan­dard

New in this edition:

  • ESD test require­ments have been changed for con­tacts of plugs and sock­ets. Addi­tion­ally, require­ments for hor­i­zon­tal cou­pling plane and ver­ti­cal cou­pling plane have been changed;
  • Require­ments are changed for large floor stand­ing equip­ment in RF con­ducted sus­cep­ti­bil­ity tests. EUT setup dif­fers from require­ments defined in IEC 610004-6:2013;
  • Alter­na­tive RF radi­ated sus­cep­ti­bil­ity test­ing method have been intro­duced– IEC 61000422;
  • No require­ment to apply pulses line-​ground for EUT with­out ground con­nec­tion in surge tests;


Scope
Appli­ances and sim­i­lar appa­ra­tus for house­hold and sim­i­lar pur­poses with rated volt­age up to 250V for sin­gle phase equip­ment and up to 480V for other equip­ment (includ­ing bat­tery pow­ered devices).
Equip­ment may include motors, heat­ing ele­ments, elec­tronic cir­cuits pow­ered by bat­ter­ies, mains power, trans­form­ers or dif­fer­ent elec­tri­cal power source.
The fol­low­ing equip­ment is included in the scope of EN 550142:2015 is:

  • microwave ovens for domes­tic use and catering;
  • cook­ing hobs and cook­ing ovens, if RF energy is used for cooking;
  • induc­tion cook­ing appliances;
  • devices for per­sonal care equipped with UV, IR and vis­i­ble light radiators;
  • power sup­plies and bat­tery charg­ers pro­vided with or intended for devices within the scope of this standard.

Devices not intended for house­hold use, but which may require sim­i­lar immu­nity require­ments– shops, light indus­try, barns, farms, if these devices are in scope of EN 550141:2006.

The fol­low­ing equip­ment is not included in scope of EN 550142:2015 is:

  • Light­ning equipment;
  • Indus­trial equipment;
  • Cables, switches, cir­cuit barkers;
  • Med­ical equipment;
  • Mul­ti­me­dia equip­ment except toys;
  • Radio trans­mit­ters;
  • Auto­mo­tive equipment;
  • Infant mon­i­tor­ing systems.


Clas­si­fi­ca­tion
Cat­e­gory 1– devices that con­tain no elec­tronic cir­cuits (motor with switch, heat­ing ele­ments with switch, tools with motors and switches with­out elec­tronic cir­cuits).
Cat­e­gory 2– devices with elec­tronic cir­cuits with no clock higher than 15MHz (toys, tools with elec­tronic con­trol, UV and IR radi­a­tors, microwave ovens).
Cat­e­gory 3– devices that dur­ing nor­mal use are not con­nected to mains net­work and have no cables (bat­tery pow­ered devices, solar power pow­ered devices). If equip­ment is charged by con­nect­ing it to mains net­work, it should be tested also as Cat­e­gory 2 equip­ment in charg­ing mode.
Cat­e­gory 4– Devices that are in scope of 550142:2015, but not clas­si­fied as Cat­e­gory 1– Cat­e­gory 3 equip­ment.

Require­ments


Per­for­mance cri­te­rion A
The appa­ra­tus shall con­tinue to oper­ate as intended dur­ing and after the test. No degra­da­tion of per­for­mance or loss of func­tion is allowed below a per­for­mance level spec­i­fied by the man­u­fac­turer, when the equip­ment is used as intended. The per­for­mance level may be replaced by a per­mis­si­ble loss of per­for­mance. If the min­i­mum per­for­mance level or the per­mis­si­ble per­for­mance loss is not spec­i­fied by the man­u­fac­turer, either of these may be derived from the prod­uct descrip­tion and doc­u­men­ta­tion and what the user may rea­son­ably expect from the equip­ment if used as intended.

Per­for­mance cri­te­rion B
The appa­ra­tus shall con­tinue to oper­ate as intended after the test. No degra­da­tion of per­for­mance or loss of func­tion is allowed below a per­for­mance level spec­i­fied by the man­u­fac­turer, when the equip­ment is used as intended. The per­for­mance level may be replaced by a per­mis­si­ble loss of per­for­mance. Dur­ing the test, degra­da­tion of per­for­mance is how­ever allowed. No change of actual oper­at­ing state or stored data is allowed. If the min­i­mum per­for­mance level or the per­mis­si­ble per­for­mance loss is not spec­i­fied by the man­u­fac­turer, either of these may be derived from the prod­uct descrip­tion and doc­u­men­ta­tion and what the user may rea­son­ably expect from the equip­ment if used as intended.

Per­for­mance cri­te­rion C
Tem­po­rary loss of func­tion is allowed, pro­vided the func­tion is self-​recoverable or can be restored by the oper­a­tion of the con­trols.


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.
