oSIST prEN IEC 60335-2-50:2026/oprA1:2026 is the Slovene publication of a CENELEC draft amendment to the International Electrotechnical Commission (IEC) safety standard for commercial electric bains-marie. It updates the European rules for electrically operated food-holding appliances that are not intended for household and similar use, within the stated voltage limits. The draft is based on IEC 60335-2-50/A1:2025 and is read with prEN IEC 60335-2-50:2026 and prEN IEC 60335-2-50:2026/prAA:2026.

What does oSIST prEN IEC 60335-2-50:2026/oprA1:2026 specify?

oSIST prEN IEC 60335-2-50:2026/oprA1:2026 specifies safety requirements for electrically operated commercial bains-marie with rated voltage up to 250 V for single-phase appliances connected between one phase and neutral, and up to 480 V for other appliances. It is aimed at non-household use, so the intended user and installation setting matter when deciding whether the standard applies.

The amendment text is organized as changes to the Scope, Clause 3, Clause 11, Clause 12, Clause 18, Clause 20, and Annex B. In practice, that means the document mainly updates how the appliance is used, heated, powered, and protected, rather than introducing a wholly new product category.

What are the key requirements of oSIST prEN IEC 60335-2-50:2026/oprA1:2026?

• Scope and intended use - The amendment states that commercial electric bains-marie are not intended for household and similar purposes. They are used by experts or instructed persons in non-public food-processing areas such as restaurant kitchens, canteens, hospitals, bakeries and butcheries, or by laypersons in public areas such as hotel/motel common areas, canteens and self-service restaurants. For a buyer or designer, this sets the operating environment that the equipment must be matched to.

• Voltage range - The scope keeps the electrical supply limits at 250 V for single-phase appliances connected between one phase and neutral and 480 V for other appliances. That tells procurement and engineering teams which machines fall under this part.

• Heating checks - Clause 11.8 links temperature-rise limits for handles, knobs, grips, keyboards, keypads and similar parts to Table 3, and it adjusts Table 101 and Table 102 references. It also allows external accessible surfaces up to 100 mm from adjacent surfaces to exceed the usual limit by up to 25 K if the relevant part is marked with IEC 60417-5041 or equivalent text. In practice, this affects surface design, labeling and type testing.

• Battery charging - Clause 12 on charging of metal-ion batteries now says that the clause of Part 1 applies. If the appliance includes charging functions, the general requirements in Part 1 must be used as the basis.

• Endurance - Clause 18 says that the clause of Part 1 is not applicable. That matters because it removes one general endurance requirement from this particular product standard.

• Stability and mechanical hazards - Clause 20.2 requires protective enclosures, guards and similar parts to be non-detachable or interlocked, and to have adequate mechanical strength. In practical terms, safety covers and guards must stay in place or be mechanically controlled so users cannot defeat them easily.

• Battery-related annex - Annex B is deleted so that Part 1 applies without modification for battery-operated appliances, separable batteries and detachable batteries. This simplifies the battery-related route back to the general standard.

What terms does oSIST prEN IEC 60335-2-50:2026/oprA1:2026 define?

• Commercial electric bains-marie - Electrically operated bain-marie appliances covered by the standard for commercial food holding and similar use.

• Experts or instructed persons - Users who operate the appliance in non-public commercial food-processing areas, such as kitchens, canteens, hospitals, bakeries and butcheries.

• Laypersons - Users who may operate the appliance in public areas, such as hotel/motel common areas, canteens and self-service restaurants.

• Metal-ion batteries - Batteries covered by the charging clause in this amendment.

• Part 1 - The general safety part of the IEC 60335 series that this amendment applies to for certain clauses.

• IEC 60417-5041 - The symbol used when a marked part may exceed the normal temperature-rise limit within the stated surface-distance condition.

Who uses oSIST prEN IEC 60335-2-50:2026/oprA1:2026?

Manufacturers and product designers use this standard to build commercial bains-marie that fit the intended user group and electrical limits. Test laboratories and certification bodies use it for heating, stability, guarding and battery-related checks.

It is also relevant to quality managers, buyers and technical specifiers in catering, hospitality, healthcare food services, bakeries and butcheries. They use it to confirm that an appliance is suitable for the operating environment and the expected users.

What changed in oSIST prEN IEC 60335-2-50:2026/oprA1:2026 from the previous edition?

This amendment updates the scope wording, modifies Clause 3.1.9, and revises Clause 11.7 and Clause 11.8. It also replaces Clause 12 with a reference to Part 1, states that Clause 18 of Part 1 is not applicable, and modifies Clause 20.2.

The amendment further adjusts the heating tables and footnotes, adds the note about Table 3, and deletes Annex B so that Part 1 applies without modification for the battery-related topic it covered.

Which standards are used with oSIST prEN IEC 60335-2-50:2026/oprA1:2026?

• prEN IEC 60335-2-50:2026 - The base European draft standard that this amendment modifies.
• prEN IEC 60335-2-50:2026/prAA:2026 - The related draft amendment that the document is read with.
• IEC 60335-2-50/A1:2025 - The international amendment text on which this draft is based.
• Part 1 - The general requirements part used directly in Clauses 12 and 18 and after Annex B is deleted.

What does the oSIST prEN IEC 60335-2-50:2026/oprA1:2026 document contain?

This document contains amendment text rather than a full reissue of the product standard. The detailed technical content sits in the changed clauses and in the referenced tables and figure, especially Table 3, Tables 101 and 102, and Figure 102.

It also includes the European foreword and the procedural material for the draft amendment, including the enquiry status and the proposed national implementation dates. For users, the practical work is to apply the changed scope, temperature-rise rules, battery provisions, guarding requirements and Annex B deletion to design and conformity assessment.

FOREWORD
1) The International Electrotechnical Commission (IEC) is a worldwide organization for standardization comprising
all national electrotechnical committees (IEC National Committees). The object of IEC is to promote international
co-operation on all questions concerning standardization in the electrical and electronic fields. To this end and
in addition to other activities, IEC publishes International Standards, Technical Specifications, Technical Reports,
Publicly Available Specifications (PAS) and Guides (hereafter referred to as "IEC Publication(s)"). Their
preparation is entrusted to technical committees; any IEC National Committee interested in the subject dealt with
may participate in this preparatory work. International, governmen
