EN IEC 60335-2-66:2026/A11:2026 is a CENELEC amendment to the European safety standard for household and similar electrical appliances, Part 2-66 for water-bed heaters. It updates the requirements for electric water-bed heaters and their associated control units with rated voltage not more than 250 V, including DC supplied appliances. The document is meant for people who design, test, certify, or specify these products.
What does EN IEC 60335-2-66:2026/A11:2026 specify?
EN IEC 60335-2-66:2026/A11:2026 specifies amendments to the existing European Standard EN IEC 60335-2-66:2026. It is read together with the base Part 2-66 and with the general safety standard EN IEC 60335-1:2023+A11:2023+A12:2026.
The scope stays focused on the safety of electric water-bed heaters and their associated control units for household and similar use. The amendment refines how the standard treats foreseeable hazards in the home, including people and domestic animals around the appliance.
| Annex | What it covers |
|---|---|
| Annex ZA | Normative references to international publications and their corresponding European publications |
| Annex ZZA | Relationship to Directive 2014/35/EU - marked not applicable |
| Annex ZZB | Relationship to Regulation (EU) 2023/1230 - marked not applicable |
| Annex ZZC | Relationship to Directive 2014/53/EU - marked not applicable |
What are the key requirements of EN IEC 60335-2-66:2026/A11:2026?
EN IEC 60335-2-66:2026/A11:2026 mainly changes the way the product is described and the way users must be instructed. In practice, the amendment pushes manufacturers to address household use more explicitly, especially around children, people with reduced abilities, and domestic animals.
Clause 1, Scope - The text now frames the standard around reasonably foreseeable hazards from intended use in and around the home. For a designer or buyer, this means the safety review has to consider normal domestic situations, not only ideal operating conditions.
Clause 7, Marking and instructions - 7.12 - The instructions must state that persons with reduced physical, sensory or mental capabilities, or with lack of experience and knowledge, may use the appliance when supervised or instructed by a responsible person. This matters because the user information must be written clearly enough to support safe household use.
Clause 7, Marking and instructions - 7.12 - The instructions must also tell users to supervise children and domestic animals so they do not play with the appliance. That makes the intended home environment part of the safety message, not an afterthought.
Clause 7, Marking and instructions - 7.12 - Cleaning and user maintenance must not be carried out by children. This affects the wording of manuals, labels, and warnings that accompany the appliance.
Annex ZA - ISO 2439 is added as a normative reference, with the European adoption EN ISO 2439. Where flexible cellular polymeric materials are relevant, the document points users to the indentation hardness method needed for evaluation.
Annexes and related parts - The amendment is applied with the annexes of Part 1 and Part 2, and it supplements or modifies the corresponding clauses in EN IEC 60335-1:2023+A11:2023+A12:2026 and EN IEC 60335-2-66:2026. In practice, conformity work has to follow the general household-appliance safety rules as well as the water-bed-heater-specific ones.
What terms does EN IEC 60335-2-66:2026/A11:2026 define?
- Electric water-bed heaters - Appliances intended to heat water beds for household and similar use.
- Associated control units - The control equipment used with the heater to manage its operation.
- Direct current (DC) - Electrical supply using direct current, which is included in the scope.
- CENELEC - The European Committee for Electrotechnical Standardization, which approved the amendment.
- dop - The latest date for national implementation by publication or endorsement.
- dow - The latest date for withdrawing conflicting national standards.
Who uses EN IEC 60335-2-66:2026/A11:2026?
EN IEC 60335-2-66:2026/A11:2026 is used by manufacturers of water-bed heaters and control units, test laboratories, conformity assessment bodies, and quality or compliance managers. It is also useful for buyers and specifiers who need to check that a product is designed and documented for domestic safety expectations. The standard helps these users align product design, instructions, and testing with the same European safety framework.
What changed in EN IEC 60335-2-66:2026/A11:2026 from the previous edition?
EN IEC 60335-2-66:2026/A11:2026 supersedes EN IEC 60335-2-66:2003. The amendment introduces requirements and instructions addressing children, people with disabilities, and domestic animals. It also updates the scope wording, the user-instruction text in Clause 7, the normative references in Annex ZA, and the bibliography.
Which standards are used with EN IEC 60335-2-66:2026/A11:2026?
- EN IEC 60335-1:2023+A11:2023+A12:2026 - The general safety requirements for household and similar electrical appliances, used together with this particular part.
- EN IEC 60335-2-66:2026 - The base Part 2-66 standard that this amendment modifies.
- ISO 2439 / EN ISO 2439 - The referenced method for determining hardness of flexible cellular polymeric materials.
- ISO 13732-1 / EN ISO 13732-1 - Added in the bibliography as a related reference.
What does the EN IEC 60335-2-66:2026/A11:2026 document contain?
EN IEC 60335-2-66:2026/A11:2026 is structured as a set of targeted amendments, not a full standalone rewrite. It contains the European foreword, changes to the Introduction, Scope, Clause 7 on marking and instructions, modifications to annexes, and a bibliography update.
The annex section includes the normative references annex and three informative relationship annexes for EU legislation. The bibliography addition points readers to ISO 13732-1, while Annex ZA adds ISO 2439 for material-related evaluation where relevant.
