Elec­tri­cal tool cer­ti­fi­ca­tion

RF EMC DEVEL­OP­MENT offers elec­tri­cal tool cer­ti­fi­ca­tion, elec­tri­cal tool Dec­la­ra­tion of Con­for­mity and elec­tri­cal tool CE mark­ing.

This requires at least one elec­tri­cal tool sam­ple to carry out test­ing and elec­tri­cal tool doc­u­men­ta­tion (tech­ni­cal file).

Cer­ti­fi­ca­tion or Dec­la­ra­tion of Con­for­mity is manda­tory for elec­tri­cal tool to enter Euro­pean Union mar­ket and to be on marked. Cer­ti­fi­ca­tion and Dec­la­ra­tion of Con­for­mity pro­ce­dures are dif­fer­ent in the aspect– who is car­ry­ing out the pro­ce­dure. Cer­ti­fi­ca­tion is car­ried out by Euro­pean Union Noti­fied body (NB). Dec­la­ra­tion of Con­for­mity is car­ried out by man­u­fac­turer or manufacturer’s rep­re­sen­ta­tive in Euro­pean Union. It is obvi­ous that, Dec­la­ra­tion of Con­for­mity is less expen­sive (usu­ally by ~30% cheaper), than cer­ti­fi­ca­tion car­ried out by third party. Com­mon part of both pro­ce­dures is test­ing; it must be done in both cases.

RF EMC DEVEL­OP­MENT have reviewed elec­tri­cal tool cer­ti­fi­ca­tion and Dec­la­ra­tion of Con­for­mity pro­ce­dures in seven easy steps. These pro­ce­dures are also applied to other elec­tri­cal and elec­tronic equip­ment, chang­ing direc­tives and stan­dards.


House­hold equip­ment cer­ti­fi­ca­tion pro­ce­dure:

1. It is nec­es­sary to receive at least one house­hold equip­ment sam­ple (To cer­tifi­cate house­hold equip­ment, it is nec­es­sary to carry out test­ing in ISO17025 accred­ited lab­o­ra­tory. Basi­cally, house­hold equip­ment two Euro­pean Union direc­tives are applied:

• Low Volt­age Direc­tive (LVD) 2014/​35/​EC,
• Elec­tro­mag­netic com­pat­i­bil­ity direc­tive (EMC) 2014/​30/​EC.

• Machin­ery (MD) 2006/​42/​EC

2. EMC test­ing (house­hold equip­ment is tested in elec­tro­mag­netic com­pat­i­bil­ity lab­o­ra­tory (EMC) accord­ing to fol­low­ing standards:

• EN 55014‒1 Elec­tro­mag­netic com­pat­i­bil­ity — Require­ments for house­hold appli­ances, elec­tric tools and sim­i­lar appa­ra­tus — Part 1: Emission,
• EN 55014 – 2 Elec­tro­mag­netic com­pat­i­bil­ity — Require­ments for house­hold appli­ances, elec­tric tools and sim­i­lar appa­ra­tus — Part 2: Immunity,
• EN 61000−3−2 Elec­tro­mag­netic com­pat­i­bil­ity (EMC) — Part 3 – 2: Lim­its — Lim­its for har­monic cur­rent emis­sions (equip­ment input cur­rent ≤16 A per phase)
• EN 61000−3−3 Elec­tro­mag­netic com­pat­i­bil­ity (EMC) — Part 3 – 3: 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 61000‒3‒3:2008))

Other stan­dards may be used for pro­fes­sional equip­ment.


3. LVD test­ing (Elec­tri­cal tool is tested in LVD lab­o­ra­tory. Applied stan­dards depends on prod­uct fam­ily)

4. Tech­ni­cal file review (Tech­ni­cal infor­ma­tion is reviewed– schemat­ics, PCB draw­ings, com­po­nent list, con­struc­tion draw­ings etc.)

If upper defined steps 2 – 4 are not suc­cess­fully passed
5. Development/​troubleshooting (Elec­tri­cal tool man­u­fac­turer receives fail­ing EMC and LVD test reports and caries out elec­tri­cal tool improve­ments to pass EMC test­ing and LVD test­ing and tech­ni­cal file review. RF EMC DEVEL­OP­MENT can offer help in this stage to reduce time required for elec­tri­cal tool cer­ti­fi­ca­tion).

6. Elec­tri­cal tool cer­ti­fi­ca­tion (Cer­ti­fi­ca­tion is car­ried out by Euro­pean Union Noti­fied body).

7. Doc­u­men­ta­tion trans­fer to elec­tri­cal tool man­u­fac­turer (Doc­u­men­ta­tion includes:

• Elec­tri­cal tool EMC test report,
• Elec­tri­cal tool LVD test report,
• Elec­tri­cal tool tech­ni­cal file,
• Elec­tri­cal tool Certificate,
• Elec­tri­cal tool CE mark).
