Elec­tro­mag­netic com­pat­i­bil­ity test­ing in EMC lab EN 61000−3−2

EN 61000‒3‒2:2006+A1+A2 Elec­tro­mag­netic com­pat­i­bil­ity (EMC) — Part 3 – 2: Lim­its — Lim­its for har­monic cur­rent emis­sions (equip­ment input cur­rent ≤16 A per phase)

Scope
Inter­na­tional stan­dard EN 61000‒3‒2:2006+A1+A2 is applic­a­ble for elec­tri­cal equip­ment that is sup­plied from mains net­work with volt­age not less than 220V and cur­rent up to 16A (includ­ing) to limit the har­monic com­po­nent emis­sion.

From the scope of this stan­dard the fol­low­ing equip­ment are excluded:

  • Equip­ment with rated power less than 75W, except class C equipment
  • Pro­fes­sional equip­ment with power >1kW
  • Sym­met­ri­cally con­trolled heat­ing ele­ments with power ≤200W
  • Inde­pen­dent dim­mers for incan­des­cent lumi­nar­ies with power ≤1kW


Clas­si­fi­ca­tion
Inter­na­tional stan­dard EN 61000‒3‒2:2006 +A1+A2 have clas­si­fi­ca­tion of equip­ment it cov­ers:

Class A:
• Three phase equip­ment
• House­hold appli­ances, except class D equip­ment
• Sta­tion­ary, fixed tools
• Dim­ming equip­ment intended to be com­bined with incan­des­cent lamps
• Audio equip­ment
• Other equip­ment that is not clas­si­fied as class B, class C or class D

Class B:
• portable tools
• non-​professional arc weld­ing equip­ment

Class C:
• light­ing equip­ment

Class D:
Fol­low­ing type equip­ment with power less than 600W (includ­ing):
• Per­sonal com­put­ers and sim­i­lar
• Tele­vi­sion receivers

Exam­ples
Class A– fre­quency con­vert­ers, cook­ing appli­ances, fixed wood­work­ing equip­ment, light­ing dim­mers, audio ampli­fiers, sub­woofers, heaters with reg­u­la­tion.
Class B– drills, elec­tri­cal ham­mers, portable min­ing equip­ment, non-​professional arc weld­ing equip­ment.
Class C– LED light­ing, LED street light­ing and other light­ing equip­ment.
Class D– Per­sonal com­put­ers, tablets, lap­tops, TV.

Require­ments
Con­ducted emis­sion require­ments cov­ered by this stan­dard are up to 40th har­monic.

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.
