Overview

EN 60335-2-73:2003/A11:2021 is a European amendment published by CENELEC that supplements Part 2-73 of the EN 60335 series. It addresses safety for fixed immersion heaters and related household and similar electrical appliances. The amendment was prepared by CLC/TC 61 and approved in February 2021 to update the original 2003 standard.

Scope (as provided): Deals with the safety of electric thermal-storage room heaters intended to heat the room in which they are located, their rated voltage being not more than 250 V for single phase and 480 V for other appliances.

This amendment clarifies applicable clauses and harmonization with EU requirements under the Low Voltage Directive (2014/35/EU), offering a practical route to conformity for manufacturers and compliance bodies.

Key Topics

• Amendment A11 content: modifications to the Introduction, Scope, Clause 6 (Classification), Clause 7 (Marking and instructions), Clause 19 (Abnormal operation), and updates to annexes and bibliography.
• Safety focus: mitigation of electrical and thermal hazards, clearer labelling and instructions, and handling of abnormal operation conditions.
• Regulatory conformity: Annex ZZA provides the relationship between the standard and the safety objectives of Directive 2014/35/EU, enabling a presumption of conformity when cited in the Official Journal.
• Standards governance: prepared by CLC/TC 61 and subject to CENELEC rules for national adoption and withdrawal timelines (latest implementation and withdrawal dates specified in the amendment).

Applications

This standard and its amendment are directly applicable to:

• Manufacturers of fixed immersion heaters and electric thermal-storage room heaters for domestic and similar use.
• Product designers and compliance engineers seeking to ensure safe design, correct marking and instructions, and documented handling of abnormal operation.
• Certification bodies and testing laboratories assessing conformity to the EN 60335 family and LVD requirements.

Practical benefits include:

• Improved product safety through standardised requirements for electrical and thermal risk reduction.
• Clearer documentation expectations (labelling, instructions) to reduce misuse and support compliance testing.
• Regulatory clarity for placing products on the EU market when the standard is cited under the Low Voltage Directive.

Related Standards

• EN 60335-1 (Part 1) - general safety requirements for household electrical appliances, referenced and supplemented by this amendment.
• Other Part 2 series standards harmonized with IEC equivalents (listed in the bibliography of the amendment), such as EN 60335-2-15, EN 60335-2-21, EN 60335-2-35, EN 60335-2-55, EN 60335-2-74.

For manufacturers and assessors, reference to EN 60335-2-73:2003/A11:2021 ensures alignment with CENELEC's interpretation of safety objectives and provides a documented pathway to demonstrate compliance with EU low-voltage safety requirements.
