Overview

EN 60335-2-66:2003/A11:2019 is a CENELEC amendment that updates the European safety requirements for water‑bed heaters used in household and similar electrical appliances. Published as part of the EN 60335 series, this amendment (A11) modifies the original Part 2-66 standard and is intended to be read together with EN 60335-1:2012 (Part 1). The amendment was approved in 2019 and includes changes to scope, marking/instructions and heating control requirements, plus a revised Annex ZZA linking the standard to the Low Voltage Directive (2014/35/EU) for conformity assessment.

Keywords: EN 60335-2-66:2003/A11:2019, water-bed heaters, household electrical appliances, safety standard, CENELEC, Low Voltage Directive.

Key topics and technical requirements

• Scope refinement: Clarifies reasonably foreseeable hazards and explicitly notes limitations regarding unsupervised use by very young children and children at play; recognizes that very vulnerable persons may need additional measures.
• Marking and instructions (Clause 7 modifications):
  • Mandatory warning symbol or text: “Not to be used by very young children (0–3 years)”.
  • Instructions must explain symbol meanings and specify control settings for continuous use.
  • Additional user-safety statements required: warnings about persons insensitive to heat, age-based usage guidance (children 3–8 only with preset controls or adult instruction).
• Heating controls (Clause 11 modifications):
  • Clarifies test/setup condition: controls are set to the highest (maximum user temperature) position for specified verifications.
• Annex ZZA (informative):
  • Establishes the relationship between the standard’s clauses and the safety objectives of Directive 2014/35/EU, providing a presumption of conformity when the standard is cited in the Official Journal.

Applications and who uses it

• Manufacturers and product designers developing water‑bed heating systems to ensure safe design and regulatory compliance.
• Technical writers and compliance teams preparing instruction manuals, warnings, and user labels consistent with Clause 7 requirements.
• Test laboratories and certification bodies performing safety testing and conformity assessment under the Low Voltage Directive.
• Regulatory authorities and notified bodies evaluating CE marking evidence and harmonized standard application.
• Retailers and importers verifying supplier compliance before placing products on the EU market.

Related standards

• EN 60335-1:2012 (Part 1) - General requirements for household and similar electrical appliances.
• Annex ZZA - Links EN 60335-2-66:2003/A11:2019 to Directive 2014/35/EU for conformity presumption.

This amendment targets safer designs, clearer user information, and harmonized compliance pathways for water‑bed heaters within the EU market.
