SIST EN IEC 60335-2-66:2026/A11:2026 is the Slovenian version of EN IEC 60335-2-66:2026/A11:2026, published by SIST and prepared within CENELEC. It is a European amendment to the household appliance safety standard for water-bed heaters, updating the Part 2-66 requirements and the instructions that go with these appliances.
What does SIST EN IEC 60335-2-66:2026/A11:2026 specify?
SIST EN IEC 60335-2-66:2026/A11:2026 specifies amendments to the safety standard for water-bed heaters used as household and similar electrical appliances. The amendment is read together with EN IEC 60335-2-66:2026 and the general safety requirements in Part 1.
The document is organized as a short amendment with changes to the Introduction, Clause 1 on Scope, Clause 7 on Marking and instructions, the annexes, and the Bibliography.
| Annex | What it covers |
|---|---|
| Annex ZA | Normative references to international publications and the added reference to ISO 2439 |
| Annex ZZA | Relationship to the safety objectives of Directive 2014/35/EU - not applicable |
| Annex ZZB | Relationship to the essential requirements of Regulation (EU) 2023/1230 - not applicable |
| Annex ZZC | Relationship to the essential requirements of Directive 2014/53/EU - not applicable |
What are the key requirements of SIST EN IEC 60335-2-66:2026/A11:2026?
SIST EN IEC 60335-2-66:2026/A11:2026 mainly changes how the safety standard treats foreseeable use, user instructions, and references. For a manufacturer or test lab, the practical effect is that the appliance documentation and compliance review must reflect the amended wording.
Clause 1 - Scope
The amendment replaces the scope wording so the document deals with reasonably foreseeable hazards of intended use for appliances encountered by all persons and domestic animals in and around the home. In practice, this places the focus on realistic home use, not just the technical appliance itself.
Clause 7.12 - Marking and instructions
SIST EN IEC 60335-2-66:2026/A11:2026 requires the instructions to state that persons with reduced physical, sensory or mental capabilities, or lack of experience and knowledge, may use the appliance when supervised or instructed by a person responsible for their safety. It also requires supervision of children and domestic animals so they do not play with the appliance, and it forbids children from carrying out cleaning and user maintenance.
For a buyer or compliance team, this means the supplied instructions must contain the specified safety messages, not just general warnings.
Introduction
The amendment deletes one word from the Introduction and turns a warning sentence into a note. This is a drafting change, but it signals that the scope and safety messaging have been aligned with the amended text.
Annexes
The annexes of Part 1 and Part 2 apply with the stated modifications. Annex ZA adds ISO 2439, which is the test method for hardness of flexible cellular polymeric materials using indentation.
Bibliography
The Bibliography adds ISO 13732-1. In practice, that gives readers a further referenced document for temperature-related safety considerations.
Status of related EU annexes
Annexes ZZA, ZZB, and ZZC are included as informative relationship annexes, and each is marked not applicable in this amendment. That tells readers the amendment text itself is not setting out those EU relationship mappings here.
What terms does SIST EN IEC 60335-2-66:2026/A11:2026 define?
SIST EN IEC 60335-2-66:2026/A11:2026 uses a few key terms in its amended wording and instructions.
- Water-bed heaters - the appliances covered by Part 2-66, intended to heat water beds.
- Reasonably foreseeable hazards of intended use - the hazards the scope now ties to normal and predictable home use.
- Reduced physical, sensory or mental capabilities - people who may use the appliance only with supervision or instruction.
- Domestic animals - animals in and around the home that must be considered in the scope and supervision instructions.
- User maintenance - maintenance that children are not allowed to perform under the amended instructions.
- Supervision - oversight required so children and domestic animals do not play with the appliance.
Who uses SIST EN IEC 60335-2-66:2026/A11:2026?
SIST EN IEC 60335-2-66:2026/A11:2026 is used by manufacturers of water-bed heaters, electrical safety engineers, test laboratories, certification bodies, and compliance or quality teams. It is also relevant to buyers and importers who need to check that product instructions and safety claims match the European safety wording for home-use appliances.
What changed in SIST EN IEC 60335-2-66:2026/A11:2026 from the previous edition?

Which standards are used with SIST EN IEC 60335-2-66:2026/A11:2026?
SIST EN IEC 60335-2-66:2026/A11:2026 is read with EN IEC 60335-2-66:2026 and with Part 1, EN IEC 60335-1:2023+A11:2023+A12:2026. Annex ZA adds ISO 2439 for hardness testing of flexible cellular polymeric materials, and the Bibliography adds ISO 13732-1.
What does the SIST EN IEC 60335-2-66:2026/A11:2026 document contain?
SIST EN IEC 60335-2-66:2026/A11:2026 contains a European foreword, then clause-by-clause amendments to the Introduction, Scope, Marking and instructions, the annexes, and the Bibliography. It also includes the implementation dates, the statement that it modifies EN IEC 60335-2-66:2026, and the Annex ZA reference table. The body of the document is mainly redline-style technical and editorial changes rather than a full rewritten standard.
