Scope
Inter­na­tional stan­dard EN 613261:2013 is applic­a­ble for elec­tri­cal equip­ment, oper­at­ing from bat­ter­ies or mains net­work with esti­mated volt­age up to 1000V AC or 1500V DC intended to be used for pro­fes­sional, indus­trial or non­in­dus­trial, man­u­fac­tur­ing, edu­ca­tional pur­poses, includ­ing equip­ment for:
  • tests and measurements;
  • con­trol;
  • lab­o­ra­tory use;
  • acces­sories intended to be used for upper men­tioned equipment.
Inter­na­tional stan­dard EN 613261:2013 also is applic­a­ble for:
  • equip­ment used in res­i­den­tial, com­mer­cial and light indus­trial envi­ron­ments, as described in EN 6100061;
  • equip­ment intended to be used in indus­trial locations;
  • equip­ment to be used in lab­o­ra­to­ries with a con­trolled elec­tro­mag­netic environment;
  • portable test and mea­sure­ment equipment.

Equip­ment used for com­pu­ta­tion and assem­blies for com­pu­ta­tion and sim­i­lar equip­ment within the scope of Infor­ma­tion Tech­nol­ogy Equip­ment (ITE) that com­plies with applic­a­ble Infor­ma­tion Tech­nol­ogy Equip­ment EMC stan­dards can be used in sys­tems within the scope of EN 613261:2013 and addi­tional test­ing is not nec­es­sary in case, if Infor­ma­tion Tech­nol­ogy Equip­ment is suit­able for the intended elec­tro­mag­netic envi­ron­ment.

Clas­si­fi­ca­tion
Inter­na­tional stan­dard EN 613261:2006 for clas­si­fi­ca­tion of equip­ment it cov­ers, have a ref­er­ence to inter­na­tional stan­dard EN 55011:2016, that sep­a­rates all equip­ment in two groups– Group 1 and Group 2, each group is sub­di­vided in two classes– class 1 and class 2.

Group 1- cov­ers all devices that are not cov­ered by group 2
Group 2- cov­ers devices that inten­tion­ally gen­er­ates RF energy in fre­quency range 9kHz-​400GHz, that is used in form elec­tro­mag­netic radi­a­tion, induc­tive cou­pling, capac­i­tive cou­pling for mate­r­ial analy­sis or inspec­tion.
Class A- cov­ers devices for usage in all estab­lish­ments other than domes­tic and that are not directly con­nected to a low volt­age power sup­ply net­work, which sup­plies domes­tic envi­ron­ment.
Class B- cov­ers devices for usage in domes­tic estab­lish­ments that are directly con­nected to a low volt­age power sup­ply net­work, which sup­plies domes­tic envi­ron­ment.

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

This equip­ment is not intended for use in res­i­den­tial envi­ron­ments and may not pro­vide ade­quate pro­tec­tion to radio recep­tion in such environments.

Exam­ples
Elec­tri­cal mea­sure­ment and test equip­ment, that records or indi­cates one or more elec­tri­cal or non-​electrical quan­ti­ties– ana­lyz­ers, gen­er­a­tors, power sup­plies, trans­duc­ers.
Equip­ment which con­trols one or more out­put quan­ti­ties to spe­cific val­ues– indus­trial process mea­sure­ment and con­trol equip­ment includ­ing, con­trollers, reg­u­la­tors, power sup­plies and power sys­tems, actu­a­tors, indi­ca­tors posi­tion­ers, shak­ers.
Lab­o­ra­tory equip­ment, that mea­sures or mon­i­tors sam­ples or is used to pre­pare sam­ples. Also in vitro equip­ment used in indus­trial premises and lab­o­ra­to­ries or domes­tic premises.

Require­ments
Equip­ment within the scope of EN 613261:2013 might be oper­ated in dif­fer­ent envi­ron­ments. Emis­sion and immu­nity test require­ments are applic­a­bil­ity depends elec­tro­mag­netic envi­ron­ment. EN 613261:2013 cov­ers three types of elec­tro­mag­netic envi­ron­ments:
• basic elec­tro­mag­netic envi­ron­ment– areas sup­plied directly by low volt­age from the pub­lic mains net­work (houses, apart­ments, shops, super­mar­kets, cin­e­mas, bars, gas sta­tions, car park­ing, bus stops, work­shops, lab­o­ra­to­ries, ser­vice cen­tres)
• indus­trial elec­tro­mag­netic envi­ron­ment– envi­ron­ment sup­plied by a sep­a­rate power net­work (high– or medium-​voltage trans­former), ded­i­cated for the sup­ply of instal­la­tions feed­ing man­u­fac­tur­ing or sim­i­lar plants with one or more of the fol­low­ing con­di­tions:
–fre­quent switch­ing of heavy inductive/​capacitive loads;
–high cur­rents and high mag­netic fields;
–pres­ence of ISM equip­ment.
• con­trolled elec­tro­mag­netic envi­ron­ment– envi­ron­ment usu­ally char­ac­ter­ized by recog­ni­tion and con­trol of EMC threats.

Lim­its
Emis­sions must sat­isfy require­ments defined in:
EN 55011:2016 Indus­trial, sci­en­tific and med­ical equip­ment– Radio-​frequency dis­tur­bance char­ac­ter­is­tics Lim­its and meth­ods of mea­sure­ment
EN 610003-2:2014 Elec­tro­mag­netic com­pat­i­bil­ity (EMC) — Part 32: Lim­its — Lim­its for har­monic cur­rent emis­sions (equip­ment input cur­rent ≤16 A per phase)
EN 6100033:2008 Elec­tro­mag­netic com­pat­i­bil­ity (EMC) — Part 33: Lim­its –Lim­i­ta­tion of volt­age changes, volt­age fluc­tu­a­tions and flicker in pub­lic low-​voltage sup­ply sys­tems, for equip­ment with rated cur­rent ≤ 16 A per phase and not sub­ject to con­di­tional con­nec­tion (IEC 6100033:2008)

Immu­nity require­ments



Per­for­mance cri­te­rion A
The equip­ment under test 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 equip­ment under test 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.

Cri­te­rion B exam­ple 1
A data trans­fer is controlled/​checked by par­ity check or by other means. In the case of mal­func­tion­ing, such as caused by a light­ning strike, the data trans­fer
will be repeated auto­mat­i­cally. The reduced data trans­fer rate at this time is accept­able.

Cri­te­rion B exam­ple 2
Dur­ing test­ing, an ana­logue func­tion value may devi­ate. After the test, the devi­a­tion van­ishes.

Cri­te­rion B exam­ple 3
In the case of a indicators/​monitors/​displays are used, it is accept­able that some degra­da­tion takes place for a short time, such as flashes dur­ing the EFT test.

Cri­te­rion B exam­ple 4
An intended change of the oper­at­ing state is allowed if self-​recoverable.


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.

Cri­te­rion C exam­ple 1
In the case of a mains power inter­rup­tion the power sup­ply unit of the equip­ment is switched off. Turn-​on may be auto­matic or car­ried out by the oper­a­tor.

Cri­te­rion C exam­ple 2
Dur­ing and after the test the proces­sor func­tions of the equip­ment stops at a defined posi­tion and is not left in a “crashed state”. The operator’s deci­sion prompts may be nec­es­sary.

Cri­te­rion C exam­ple 3
Dur­ing the surge test over­cur­rent pro­tec­tion inter­vene. As a result, over-​current pro­tec­tion device that is replaced or reset by the oper­a­tor.
