Overview

SIST EN 60335-2-35:2003/kFprA11:2013 is a European standard issued by the CLC (European Committee for Electrotechnical Standardization) that specifies particular safety requirements for household and similar electrical appliances, specifically instantaneous water heaters. This standard is an amendment to the original EN 60335-2-35:2002 and supports the essential safety principles outlined in the Low Voltage Directive (LVD 2006/95/EC).

This standard addresses safety hazards associated with instantaneous water heaters, commonly found in domestic and similar settings, to ensure protection against electrical, mechanical, and thermal risks. It complements the general standards EN 60335-1:2012 by introducing specific provisions for this type of water heating equipment.

Key Topics

• Scope and Application
  EN 60335-2-35 focuses on hazards typically encountered by all users in household environments but does not specifically cover unsupervised use by very young children or children playing with appliances. It recognizes the need to address vulnerabilities for certain users but emphasizes safe normal use conditions.

• Marking and Instructions
  The standard requires clear markings and user instructions, particularly for temperature controls on instantaneous water heaters. Temperature regulation must be easily detectable by shape or position, or be indicated with symbols or digital displays of adequate size and contrast for visibility and safety.

• Safety Requirements for Water Resistance
  Special tests are mandated to verify the water heaters’ resistance against water penetration, especially when installed in shower enclosures or above baths. It covers scenarios where moisture could affect electrical safety, requiring that no water compromises insulation or electrical clearances.

• User Accessibility and Safety
  The appliance can be safely used by children aged 3 years and above, and by persons with reduced physical, sensory, or mental capabilities, provided they receive adequate supervision and instruction.

• Compliance and Testing
  Appliances must pass rigorous electric strength tests and inspections to ensure safety criteria such as clearance and creepage distances are maintained, even under adverse moisture conditions.

Applications

EN 60335-2-35 applies primarily to the design, manufacture, and testing of instantaneous water heaters intended for:

• Household use in bathrooms, kitchens, and other domestic environments.
• Similar applications such as small commercial premises or similar venues with comparable safety requirements.
• Installations where water heaters are mounted near water sources, such as above shower basins or baths, demanding enhanced moisture resistance.

By adhering to this standard, manufacturers ensure the reliable and safe operation of water heaters, reducing risks of electric shock, fire, and other hazards related to water heating equipment. The standard facilitates regulatory compliance within the European Economic Area, supporting the safe market penetration of products.

Related Standards

• EN 60335-1:2012 – General requirements for the safety of household and similar electrical appliances. EN 60335-2-35 acts as a supplement specifying particular rules tailored for instantaneous water heaters.
• EN 60335-2-5:2003 + A1:2005 + A2:2008 + A11:2009 – Pertains to dishwashers, referenced in EN 60335-2-35 to cover specific test substances and conditions related to moisture resistivity.
• ISO/TR 22411:2011 – Provides ergonomic guidance on marking contrast and usability to accommodate older persons and individuals with disabilities, ensuring the safety marking provisions in the standard are practical and accessible.

Manufacturers and testing laboratories should consider these related standards to achieve full compliance and ensure that their products meet comprehensive safety requirements.
