SIST EN 60335-2-74:2003/A2:2010

SIST EN 60335-2-74:2003/A2:2010 is the Slovenian adoption of amendment A2 to the European standard for household and similar electrical appliances - safety - portable immersion heaters. It updates the safety text for this appliance family, mainly by refining the scope wording, changing one test sequence rule, and adding a bibliography reference used with the base Part 2-74 document. The amendment is intended for manufacturers, test laboratories, certifiers and others checking conformity of portable immersion heaters.

What does SIST EN 60335-2-74:2003/A2:2010 specify?

SIST EN 60335-2-74:2003/A2:2010 is an amendment, not a full standalone product standard. It modifies EN 60335-2-74:2003 for portable immersion heaters and keeps the same safety focus for household and similar electrical appliances.

The document is organized as front matter plus targeted changes to those sections. In practice, that means readers use it together with the base standard rather than as a separate complete test method.

What are the key requirements of SIST EN 60335-2-74:2003/A2:2010?

The amendment mainly clarifies how the base safety standard is applied and when one test must be carried out. It does not introduce a new product family; it adjusts the way the existing portable immersion heater requirements are read and tested.

Relationship with Part 1 and other standards

The introduction states that when Part 2 does not add a special requirement for a hazard, Part 1 applies. It also says this product-family standard takes precedence over horizontal and generic standards for the same subject. In practice, users should apply the 60335 series first and not layer in separate cross-sector hot-surface requirements unless the standard points to them.

Scope wording for intended users

Clause 1 updates the wording for people who need supervision or instruction before safe use. It explicitly includes persons, including children, whose physical, sensory or mental capabilities, or lack of experience and knowledge, prevent safe use, and it also addresses children playing with the appliance. For manufacturers and instruction writers, this means the safety information and user guidance must match these user groups.

Test sequence in Clause 5.3

Clause 5.3 changes the order of testing: the additional test of 21.1 is done before the tests of Clause 8. That matters for laboratories because test order can affect results and repeatability. A lab plan should follow this sequence exactly when applying the standard.

Hot-surface reference in the bibliography

The bibliography adds ISO 13732-1, the ergonomics standard for assessing human response to contact with hot surfaces. In practice, this gives a named reference for evaluating burn-related hazards where hot surfaces are involved.

What terms does SIST EN 60335-2-74:2003/A2:2010 define?

• Portable immersion heaters - Appliances covered by Part 2-74 that are intended to heat liquid by immersion.
• Part 1 - The general safety standard in the IEC 60335 series that applies where Part 2-74 has no special rule.
• Product family standard - A standard written for one appliance family, with priority over horizontal and generic standards for the same hazard.
• Horizontal and generic standards - Cross-sector standards for one hazard, such as hot surfaces, used across many products.
• CENELEC - The European electrotechnical committee that approved the amendment for national adoption.
• IEC TC 61 - The IEC technical committee for safety of household and similar electrical appliances.
• ISO 13732-1 - The hot-surface ergonomics standard added to the bibliography.

Who uses SIST EN 60335-2-74:2003/A2:2010?

Manufacturers of portable immersion heaters use this amendment when designing products and preparing technical files. Test laboratories and certification bodies use it to run and order the required safety tests in the correct sequence. Quality managers, compliance teams and buyers use it to check that supplier products and instructions match the safety approach for household and similar electrical appliances.

What changed in SIST EN 60335-2-74:2003/A2:2010 from the previous edition?

SIST EN 60335-2-74:2003/A2:2010 is amendment A2 to EN 60335-2-74:2003 and IEC 60335-2-74:2002/A2:2009. The amendment changes the introduction, updates the scope wording for supervised users and children, moves the additional test of 21.1 to before the Clause 8 tests, and adds ISO 13732-1 to the bibliography.

Which standards are used with SIST EN 60335-2-74:2003/A2:2010?

• Part 1 of the IEC 60335 series - Applies where Part 2-74 has no additional requirement for a hazard.
• ISO 13732-1 - Provides the hot-surface assessment reference added to the bibliography.
• EN 60335-2-74:2003 - The base European standard that this amendment modifies.
• IEC 60335-2-74:2002/A2:2009 - The international amendment text on which the European amendment is based.

What does the SIST EN 60335-2-74:2003/A2:2010 document contain?

The document contains amendment instructions rather than a full rewritten safety standard. It gives front matter, a foreword with approval and implementation dates, an introduction on how Part 1 and Part 2 work together, and specific edits to Clause 1, Clause 5.3 and the bibliography. It is therefore mainly used to update application, testing and reference information for portable immersion heaters.
