SIST EN 60335-2-74:2003/A11:2018

Overview

SIST EN 60335-2-74:2003/A11:2018 is a European safety standard developed by the CLC (European Committee for Electrotechnical Standardization) specifically for portable immersion heaters. This standard sets out the particular safety requirements for household and similar electrical appliances with a rated voltage not exceeding 250 V. It covers devices intended for domestic use, as well as applications in shops, light industry, and farming environments where laymen may operate these appliances.

The latest amendment (A11) published in 2018 updates the original 2003 standard, incorporating changes approved by CENELEC in 2016 to ensure compliance with evolving safety regulations and practical usage considerations. This standard aligns with the EU Low Voltage Directive 2014/35/EU, providing manufacturers with a harmonized framework to demonstrate conformity and market their portable immersion heaters safely within the European Union and associated countries.

Key Topics

• Scope and Applicability:
  The standard addresses reasonably foreseeable hazards associated with portable immersion heaters used by all persons excluding unsupervised children. It specifically excludes considerations for children playing with or maintaining the appliances. This ensures that safety requirements focus on typical use scenarios in domestic and similar environments.

• User Capability Requirements:
  The standard recognizes users with reduced physical, sensory, or mental capabilities, provided they have received appropriate supervision or instruction. It emphasizes that cleaning and user maintenance activities should not be performed by children to reduce the risk of accidents.

• Safety Requirements:
  EN 60335-2-74 outlines essential safety criteria such as electrical insulation, protection against electric shock, temperature controls to prevent overheating, and mechanical stability. It complements the general safety clauses in EN 60335-1, focusing on portable immersion heaters' specific risks.

• Marking and Instructions:
  Clear markings and operational instructions must be provided to inform users about safe handling, voltage limits, and use limitations. This aids in reducing misuse and accidents during operation, cleaning, and maintenance.

• Legal and Regulatory Compliance:
  The standard supports harmonization under the EU Low Voltage Directive, giving manufacturers a voluntary means of compliance with applicable legal safety objectives, facilitating market access across member countries.

Applications

SIST EN 60335-2-74:2003/A11:2018 is directly applicable to the design, manufacturing, testing, and certification of portable immersion heaters used in various settings:

• Household Use:
  Ensuring the safety of portable immersion heaters utilized in typical home environments for heating liquids.

• Commercial Shops:
  Guiding manufacturers supplying immersion heaters intended for use by retail personnel or consumers in shops.

• Light Industrial Settings:
  Covering applications where immersion heaters are operated by workers for low-risk, light industrial processes.

• Agricultural and Farm Use:
  Enabling safe use in farming environments, where workers or operators may require portable heating appliances.

Manufacturers, importers, and testing laboratories rely on this standard to mitigate electrical, thermal, and mechanical hazards, ensuring user safety and regulatory compliance.

Related Standards

• EN 60335-1: General safety requirements for household and similar electrical appliances, which serves as the foundational standard complemented by specific parts such as EN 60335-2-74.

• Low Voltage Directive (2014/35/EU):
  The European Union directive mandating electrical equipment safety requirements for products with voltages between 50 V and 1000 V AC and 75 V to 1500 V DC. EN 60335-2-74 aligns with this directive.

• Other EN 60335-2 Series Standards:
  Cover specific appliances and their safety requirements, such as heaters, kitchen devices, and personal care appliances, ensuring a broad safety regime across electrical household equipment.
