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)
EN 50144−2−13 Safety of hand-held electric motor operated tools. Particular requirements for chain saws.
EN 50144−2−15 Safety of hand– held electric motor operated tools. Particular requirements for hedge trimmers.
EN 50338 Safety of household and similar electrical appliances — Particular requirements for pedestrian-controlled battery powered electrical lawn mowers.
Lawn trimmers and lawn edge trimmers
EN 60335−2−91 Household and similar electrical appliances, safety. Particular requirements for walk-behind and hand-held lawn trimmers and lawn edge trimmers.
Drills and impact drills
EN 60745−2−1 Hand-held motor-operated electric tools, safety. Particular requirements for drills and impact drills.
Screwdrivers and impact wrenches
EN 60745−2−1 Hand-held motor-operated electric tools, safety Particular requirements for screwdrivers and impact wrenches.
Grinders, polishers and disk-type sanders
EN 60745−2−3 Hand-held motor-operated electric tools, safety. Particular requirements for grinders, polishers and disk-type sanders.
EN 60745−2−5 Hand-held motor– operated electric tools, safety. Particular requirements for circular saws.
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).
