Household and similar electrical appliances - Safety -- Part 1: General requirements

Gives safety of electrical appliances for hausehold and similar  use such as appliances intended to be used by laymen in  shops, in light industry and on farm, the rated voltage of the  appliances being not more than 250 V for single-phase  appliances, 480 V for other appliances. This standard does not  deal appliances intended exclusively for industrial purposes,  used in locations where special conditions prevail, appliances  for medical purposes, electronic equipment, personal  computers, blankets, pads and similar flexible heating  appliances.

Overview

EN 60335-1:2002/A1:2004 (CENELEC) is the European amendment to the international safety standard IEC 60335‑1:2001 for household and similar electrical appliances - Part 1: General requirements. Approved 22 Sep 2004 and including the January 2007 corrigendum, this amendment updates and supplements EN 60335‑1:2002 and defines general safety principles, test requirements and normative annexes applicable across a wide range of domestic electrical appliances.

Key topics and requirements

• General safety scope: requirements to protect against electric shock, fire and mechanical hazards in normal and reasonably foreseeable abnormal conditions. The amendment emphasizes how electromagnetic phenomena can affect safe operation.
• Software and electronic controls: Annex R (normative) introduces software evaluation (referencing IEC 60730‑1) and Annex Q (informative) describes test sequences for evaluating electronic circuits.
• Environmental and climatic guidance: Annex P (informative) provides guidance for appliances used in damp, warm, equable climates.
• Fire and material tests: normative references include glow‑wire and hot‑wire tests (IEC 60695 series), flammability and tracking tests (IEC 60112, IEC 60695).
• Electromagnetic compatibility (EMC): references to IEC 61000 series for immunity tests (ESD, radiated RF, fast transients, surge, harmonics).
• Mechanical and electrical components: requirements for cable and conduit dimensions, appliance couplers (IEC 60320), lamp holders, connectors and protective devices.
• Annex structure & national deviations: Annexes B–N and R are normative parts of the standard; Annexes A, L, O, P, Q are informative. Annex ZA/ZB list special national conditions and deviations (examples: Ireland/UK, Germany).

Applications and who uses it

• Appliance manufacturers and design engineers: to design products that meet European safety requirements for domestic appliances.
• Test laboratories and conformity assessors: to perform required mechanical, electrical, EMC and software evaluations.
• Regulatory and compliance teams: to demonstrate national implementation (endorsed/identical national standards) and track country deviations.
• Procurement and product safety officers: to specify compliant appliances for markets across CENELEC member countries.

Related standards (examples referenced)

• IEC 60335‑1 (base standard), IEC 60730‑1 (automatic electrical controls / software evaluation)
• EMC test standards: IEC 61000‑4 series
• Fire and flammability: IEC 60695 series; tracking index: IEC 60112
• Appliance couplers and connectors: IEC 60320, IEC 60061

EN 60335‑1:2002/A1:2004 is essential for anyone responsible for the safety, testing and regulatory compliance of household electrical appliances sold in Europe. Keywords: EN 60335‑1, IEC 60335‑1, appliance safety, software evaluation, EMC, glow‑wire, household electrical appliances.

The insulation is raised to the temperature measured during the test of Clause 11. The
surface of the insulation is then scratched by means of a hardened steel pin, the end of which
o

o o
0,25 mm ± 0,02 mm. The pin is held at an angle of 80 – 85 to the horizontal and loaded so
that the force exerted along its axis is 10 N ± 0,5 N. The scratches are made by drawing the
pin along the surface of the insulation at a speed of approximately 20 mm/s. Two parallel
scratches are made. They are spaced sufficiently apart so that they are not affected by each
other, their length covering approximately 25 % of the length of the insulation. Two similar
o
scratches are made at 90 to the first pair without crossing them.

approximately 10 N. No further damage, such as separation of the material, shall occur. The
insulation shall then withstand the electric strength test of 16.3.
The hardened steel pin is then applied perpendicularly with a force of 30 N ± 0,5 N to an
unscratched part of the surface. The insulation shall then withstand the electric strength test
of 16.3 with the pin still applied and used as one of the electrodes.

Non-self-resetting thermal motor protectors shall have a trip-free action unless they are
voltage maintained.
NOTE 2 Trip-free is an automatic action that is independent of manipulation or position of the actuating member.
Reset buttons of non-self-resetting controls shall be located or protected so that their
accidental resetting is unlikely to occur if this could result in a hazard.
NOTE 3 For example, this requirement precludes the location of reset buttons on the back of an appliance, which
could result in them being reset by pushing the appliance against a wall.
Compliance is checked by inspection.
