BS EN 60335-1:2012, “Household and similar electrical appliances. Safety. General requirements,” has just been released and is now available from Document Center Inc. The 198 page standard is the UK implementation of EN 60335-1:2012.
BS EN 60335-1 deals with the safety of electrical household appliances – providing their rated voltage is not more than 250 V for single-phase and 480 V for other appliances. These best practice recommendations for electrical safety look at common hazards of household equipment or electrically-operated devices that could cause injury to persons in and around the house.
The standard explains heating, void as well as leakage currents and electric strength at operating temperatures. Other topics include moisture resistance, stability and mechanical hazards, internal wiring and connections.
BS EN 60335-1 looks at the general requirements and conditions to test the domestic safety of electric household appliances. It also defines the classification and marking of electrical equipment, and demonstrates how to ensure protection against live parts.
It is derived from IEC 60335-1:2010, incorporating corrigendum July
2010. It supersedes BS EN 60335-1:2002+A15:2011, which will be
withdrawn on 21 November 2014.
Battery-operated appliances and other d.c. supplied appliances are within the scope of this standard. Appliances not intended for normal household use but which nevertheless may be a source of danger to the public, such as appliances intended to be used by laymen in shops, in light industry and on farms, are within the scope of this standard. Examples of such appliances are catering equipment, cleaning appliances for commercial use, and appliances for hairdressers.
The principal changes in this edition are as follows:
– updated the text of the standard to align with the most recent editions of the dated normative references;
– modified the functional safety requirements using programmable electronic circuits including software validation requirements;
– updated Clause 29 to cover insulation requirements subjected to high frequency voltages as in switch mode power supply circuits;
– updated Subclause 30.2 to further align the pre-selection option with the end-product test option;
– deleted some notes and converted many other notes to normative text;
– clarified requirements for class III constructions.
National Annex NA (informative) reproduces the original IEC
60335-1:2010 text prior to amendment or deletion by the CENELEC
The Ireland and United Kingdom special national condition in Clause
25.8 of Annex ZA is missing the values in parentheses, which were
introduced in the 2007 corrigendum to BS EN 60335-1:2002. It is
expected that a CENELEC corrigendum will be issued to amend this.
