FprEN IEC 60335-2-74:2026/FprAA:2026

prEN IEC 60335-2-74:2026/prAA:2026 is a CENELEC draft amendment to the European standard for the safety of portable immersion heaters. It modifies EN IEC 60335-2-74:2026 for household and similar electrical appliances with rated voltage not above 250 V, including appliances intended for laymen in shops, light industry and farms. The amendment focuses on foreseeable hazards, user instructions, heating checks and the linked annexes.

What does prEN IEC 60335-2-74:2026/prAA:2026 specify?

prEN IEC 60335-2-74:2026/prAA:2026 specifies changes to the European standard for portable electric immersion heaters. In practice, it is an amendment document: it does not stand alone, but modifies the base Part 2 standard and is read with it.

The document is organized as clause-by-clause modifications to the Introduction, Scope, Normative references, Marking and instructions, Heating, the annexes, and the Bibliography. It also shows the European foreword and the usual CENELEC publication information.

What are the key requirements of prEN IEC 60335-2-74:2026/prAA:2026?

prEN IEC 60335-2-74:2026/prAA:2026 mainly strengthens the safety wording for users, children and domestic animals, and aligns the standard with the base Part 1 requirements. The most important changes are in Scope, instructions, heating, and the annexes.

Scope and hazard focus

The Scope is rewritten to emphasize reasonably foreseeable hazards from intended use that may be encountered by all persons and domestic animals in and around the home. For a reader, this means the safety view is broader than the appliance alone - it covers the way people and animals may come into contact with it during normal use.

Marking and instructions

Clause 7 changes the user instructions so they must cover supervised use by persons with reduced physical, sensory or mental capabilities, or lack of experience and knowledge. The instructions must also say that children cannot use the appliance, that the appliance is to be kept out of reach of domestic animals and children, and that children shall not carry out cleaning or user maintenance. In practice, this affects the wording in manuals and product labels.

Heating tests

Clause 11 removes a sentence that allowed any measuring instrument giving the same results as the probe. This keeps the heating assessment tied more tightly to the specified test arrangement. For manufacturers and test labs, that means the heating method has to follow the stated probe-based conditions.

Relationship to Part 1 and annexes

The amendment says that the annexes of Part 1 apply with the stated modifications. Annex ZA is updated with the European publication for EN IEC 60335-1, and the text also points to the companion Part 2 standard EN IEC 60335-2-74:2026. For compliance work, this means the product has to be checked against the general Part 1 safety framework as well as the portable immersion heater requirements.

Bibliography updates

The bibliography adds IEC 60335-2-15, IEC 60335-2-55 and IEC 60335-2-73, each harmonized as EN IEC versions. These references help users trace related appliance safety documents.

What terms does prEN IEC 60335-2-74:2026/prAA:2026 define?

• Portable immersion heaters - Electric heaters designed to be immersed in liquid and moved between uses.
• Laymen - Non-professional users, here including use in shops, light industry and farms.
• CENELEC - The European electrotechnical standardization body that issues this draft amendment.
• CLC/TC 61 - The technical committee responsible for safety of household and similar electrical appliances.
• Annex ZA - The annex that maps international publications to their corresponding European publications.
• Public Enquiry - The review stage during which CENELEC members submit comments on the draft.
• Domestic animals - Animals specifically brought into the safety scope for foreseeable contact around the home.

Who uses prEN IEC 60335-2-74:2026/prAA:2026?

prEN IEC 60335-2-74:2026/prAA:2026 is used by manufacturers of portable immersion heaters, product safety engineers, test laboratories, certification bodies, and quality managers. It is also relevant to buyers and compliance teams that need to check whether a product design and its instructions match the safety expectations for household and similar use.

In practice, these users apply it when designing the appliance, writing the instructions, selecting the heating test method, and checking conformity with the Part 1 framework. It is especially relevant where the product may be used by non-professionals, or where children and domestic animals have to be considered in the safety instructions.

What changed in prEN IEC 60335-2-74:2026/prAA:2026 from the previous edition?

prEN IEC 60335-2-74:2026/prAA:2026 is stated to supersede EN 60335-2-74:2003+A1:2006+A2:2009+A11:2018 when adopted. The significant technical change named in the foreword is the introduction of requirements and instructions for children, people with disabilities and domestic animals.

It also updates the Scope wording, adds EN IEC 60335-1:2023 to the normative references, revises the instruction text in Clause 7, and adjusts Clause 11 and the annexes.

Which standards are used with prEN IEC 60335-2-74:2026/prAA:2026?

prEN IEC 60335-2-74:2026/prAA:2026 is used with EN IEC 60335-2-74:2026, which is the base Part 2 standard it amends. It also adds EN IEC 60335-1:2023 to the normative references, because Part 1 provides the general safety requirements used alongside this particular standard.

The annex text also points to EN IEC 60335-1:2023+A11:2023+prA12:2026 in Annex ZA, and the bibliography cites IEC 60335-2-15, IEC 60335-2-55 and IEC 60335-2-73 as harmonized EN IEC publications.

What does the prEN IEC 60335-2-74:2026/prAA:2026 document contain?

prEN IEC 60335-2-74:2026/prAA:2026 contains clause-by-clause amendments, not a full rewritten standard. It shows the exact areas changed in the Introduction, Scope, Normative references, Marking and instructions, Heating, the annexes, and the Bibliography.

It also includes the European foreword, the publication status information, and the annex structure used for European references and EU relationship statements. For a reader, the practical value is that it tells you exactly where the base standard is being tightened or aligned without reproducing the full Part 2 text.
