kSIST FprEN IEC 60335-2-74:2026/kFprAA:2026

kSIST FprEN IEC 60335-2-74:2026/kFprAA:2026 is a CENELEC draft amendment published by SIST for the safety standard on portable immersion heaters. It updates the requirements for portable electric immersion heaters with a rated voltage not more than 250 V, for household and similar use, including use by laymen in shops, light industry and on farms.

What does kSIST FprEN IEC 60335-2-74:2026/kFprAA:2026 specify?

kSIST FprEN IEC 60335-2-74:2026/kFprAA:2026 specifies amendment text for the European standard on portable immersion heaters. It is read together with EN IEC 60335-2-74:2026 and with Part 1, because it changes selected clauses rather than standing alone.

The scope updates the safety focus to cover reasonably foreseeable hazards of intended use encountered by all persons and domestic animals in and around the home. That matters because the document is not only about the appliance itself, but also about the wording manufacturers must use for safe use, instruction, and user awareness.

The amendment is organized as:

• modification to the Introduction
• modification to Clause 1, Scope
• modification to Clause 2, Normative references
• modification to Clause 7, Marking and instructions
• modification to Clause 11, Heating
• modification to the annexes
• modification to the Bibliography

What are the key requirements of kSIST FprEN IEC 60335-2-74:2026/kFprAA:2026?

kSIST FprEN IEC 60335-2-74:2026/kFprAA:2026 mainly revises the wording that controls how the appliance is described, instructed, and assessed. In practice, manufacturers need to check the instructions, the scope statement, and any heating-related measurement or test wording against the new text.

Scope and intended users

The amended scope states that the document deals with hazards of intended use that may be encountered by all persons and domestic animals in and around the home. For a manufacturer, this means the safety approach now explicitly includes realistic household use conditions and the presence of children and animals.

Marking and instructions

Clause 7 changes the instructions text to state that people with reduced physical, sensory or mental capabilities, or lack of experience and knowledge, may use the appliance only when supervised or instructed by a person responsible for their safety. It also states that children cannot use the appliance, that the appliance should 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 instruction manuals and any safety wording supplied with the product.

Heating

Clause 11 removes a sentence about using any measuring instrument that gives the same results as the probe. That matters for testing and conformity work because the heating assessment now follows the revised wording without that extra measurement option.

References and annexes

Clause 2 adds EN IEC 60335-1:2023 to the normative references. Annex ZA then ties the document to the European publication of Part 1. For compliance teams, this confirms that the general requirements of Part 1 remain part of the technical basis for the product standard.

What terms does kSIST FprEN IEC 60335-2-74:2026/kFprAA:2026 define?

The amendment itself is focused on modifying safety text, so the key terms are mainly those used in the revised clauses.

• Portable electric immersion heaters - appliances intended to be immersed in liquid and carried from place to place.
• Rated voltage - the declared voltage limit for the appliance; this document applies up to 250 V.
• Reasonably foreseeable hazards - risks that can be expected from normal intended use, including realistic household situations.
• Reduced physical, sensory or mental capabilities - users who may need supervision or instruction before using the appliance safely.
• Domestic animals - animals in or around the home that the amended scope and instructions explicitly consider.
• Part 1 - the general safety standard that supplies the baseline requirements used together with this Part 2-74 document.

Who uses kSIST FprEN IEC 60335-2-74:2026/kFprAA:2026?

Manufacturers of portable immersion heaters use it to align product instructions and safety wording with the European safety approach. Test laboratories and conformity assessment teams use it when checking heating-related clauses and the relationship with Part 1.

It is also relevant to quality managers, compliance engineers, and buyers who need to confirm that a portable immersion heater standard covers household and similar uses, including shop, light industry, and farm contexts. In practice, it helps these users decide whether the product documentation and test basis match the intended market.

What changed in kSIST FprEN IEC 60335-2-74:2026/kFprAA:2026 from the previous edition?

The amendment states that, with European Amendment A11, EN 60335-2-74:2003+A1:2006+A2:2009+A11:2018 is superseded.

The listed technical changes are:

• introduction of requirements and instructions for children, people with disabilities and domestic animals
• revised scope wording on reasonably foreseeable hazards and intended use
• added normative reference to EN IEC 60335-1:2023
• revised marking and instructions text in Clause 7
• deletion of a sentence in Clause 11 on measuring instruments
• updates to the annexes and bibliography

Which standards are used with kSIST FprEN IEC 60335-2-74:2026/kFprAA:2026?

kSIST FprEN IEC 60335-2-74:2026/kFprAA:2026 is read in conjunction with EN IEC 60335-2-74:2026, and Clause 2 adds EN IEC 60335-1:2023 as a normative reference. The foreword also points to EN IEC 60335-1:2023+A11:2023+prAB:2026 as the Part 1 basis affected by the amendment.

The bibliography adds IEC 60335-2-15, IEC 60335-2-55 and IEC 60335-2-73, noted as harmonized as EN IEC versions. These references help readers place the document within the wider household appliance safety series.

What does the kSIST FprEN IEC 60335-2-74:2026/kFprAA:2026 document contain?

The document contains targeted changes to the Introduction, Scope, Normative references, Marking and instructions, Heating, annexes, and Bibliography. It also includes Annex ZA with the European reference mapping for Part 1.

Annexes ZZA, ZZB and ZZC are included as relationship annexes to EU legislation and are marked not applicable in this draft. For practical use, the document is mainly a change set that tells the reader exactly where the base standard is being updated for portable immersion heaters.
