BS EN 60335-1:2012+A15:2021

What is BS EN 60335-1 - General requirements on electrical appliances about?   

BS EN 60335-1 deals with the safety of electrical appliances for household environment and commercial purposes, their rated voltage being not more than 250 V for single-phase and 480 V for others. 

Note 1: Battery-operated appliances and other d.c. supplied appliances are within the scope of this standard. Dual supply appliances, either mains-supplied or battery-operated, are regarded as battery-opera appliances when operated in the battery mode. 

Note 2: Examples of appliance for household environment are appliances for typical housekeeping functions used in the household environment that may also be used by non-expert users for typical housekeeping functions: 

• In shops, offices and other similar working environments; in farmhouses 
• By clients in hotels, motels and other residential type environments 
• In bed and breakfast type environments 

Note 3: Criteria applied for the allocation of products covered by standards in the EN 60335 series under either the Low Voltage Directive (LVD) or the Machinery Directive (MD). 

Note 4: BS EN 60335-1 doesn’t apply to: 

• Appliances intended exclusively for industrial purposes 
• Appliances intended to be used in locations where special conditions prevail, such as the presence of a corrosive or explosive atmosphere (dust, vapour or gas) 
• Audio, video and similar electronic apparatus 
• Appliances for medical purposes  
• Hand-held motor-operated electric tools 
• Personal computers and similar equipment 
• Transportable motor-operated electric tools 

Who is BS EN 60335-1 - General requirements on electrical appliances for?  

BS EN 60335-1 on electric appliance safety is useful for:  

• Electrical appliance manufacturers 
• End users 
• Electrical appliance operators 

Why should you use BS EN 60335-1 - General requirements on electrical appliances ?   

Electric appliance should be constructed in accordance with good engineering practice in relation to safety for the users.  

BS EN 60335-1 recognizes the internationally accepted level of protection against hazards such as electrical, mechanical, thermal, fire and radiation of appliances when operated as in 
normal use taking into account the manufacturer's instructions.  

BS EN 60335-1 covers abnormal situations that can be expected in practice and takes into account the way in which electromagnetic phenomena can affect the safe operation of appliances. 

BS EN 60335-1 provides general requirements to the manufacturer so as to design and construct electric appliance that conform to the principal elements of the safety. 

 What’s changed since the last update?  

BS EN 60335-1 cancels and replaces the fourth edition published in 2001 including its Amendment 1 (2004) and amendment 2 (2006).  

The principal changes in this edition as compared with the fourth edition of IEC 60335-1 are 
as follows (minor changes are not listed):
