prEN IEC 60335-2-83:2026 is a CLC draft European standard in the IEC 60335 series for the safety of electrically heated gullies for roof drainage. It specifies particular safety requirements for appliances used to de-ice the inlet of drainage systems on flat roofs, balconies, and similar structures, for rated voltages up to 250 V, including DC supplied and battery-operated appliances.

What does prEN IEC 60335-2-83:2026 specify?

prEN IEC 60335-2-83:2026 gives particular safety requirements that supplement IEC 60335-1 for heated gullies for roof drainage. In practice, that means the reader applies the general household-appliance safety rules first, then the extra requirements in this part for the roof-drainage use case.

The document is organized into clauses 1 to 32, followed by Annex B and a bibliography. The annexes of Part 1 are applicable except where this part changes them.

Annex	What it covers
Annex B	Battery-operated appliances, separable batteries, and detachable batteries for battery-operated appliances

What are the key requirements of prEN IEC 60335-2-83:2026?

The main requirements focus on electrical protection, water exposure, temperature rise, installation, and corrosion resistance. These points matter because heated gullies are installed outdoors and must remain safe when exposed to drainage water, low temperatures, and long service conditions.

Electrical safety and protection level

Clause 6 requires appliances to be class I, class II, or class III, and at least IPX7. For a designer or buyer, this means the product must be selected and verified against a defined protection class and a high level of water ingress protection.

Clause 27.1 adds that all conductive parts of class I appliances that can come into contact with drainage water shall be reliably connected to the earthing terminal. This is a direct safety measure for installations where water and metal parts may meet.

Test conditions that shape the design

Clause 5.6 requires thermostats to be short-circuited for the tests, and Clause 5.7 requires Clauses 10, 11, 13, and 19 to be tested at 40 °C ± 2 °C. In practice, the appliance must remain safe under more severe test conditions than normal room temperature.

Clause 3.1.9 modifies normal operation so that the appliance operates with a thermal insulation layer covering the top surface. This affects how temperature rise is assessed and reflects the way the appliance is installed in service.

Temperature rise and overheating control

Clause 11.7 requires the appliance to be operated until steady conditions are established, and Clause 11.8 reduces the temperature rises from Table 3 by 15 K. The surface of the enclosure, including any part inaccessible after installation, shall not exceed 60 K rise.

This matters because installers and purchasers need a product that does not create excessive surface temperatures after mounting in the roof drainage system.

Installation, access, and marking

Clause 7.12.1 requires the instructions to say that the appliance shall be installed in an area unlikely to be accessed. Clauses 8.1.1 and 20.2 specify that test probe 18 is not applied. Together, these clauses show that the design and instructions must reduce user access to live or hazardous parts after installation.

Construction, wiring, and durability

Clause 22.101 requires heating elements not to be detachable parts. Clause 24.101 requires thermal cut-outs used for compliance with 19.4 to be non-self-resetting thermal cut-outs. Clause 25.1 forbids an appliance inlet or pins for insertion into socket-outlets, and Clause 25.7 requires polychloroprene-sheathed supply cords.

Clause 21.1 also requires a mechanical strength test at -25 °C. For manufacturers, this means the appliance must stay sound both mechanically and electrically in cold outdoor conditions.

Moisture and corrosion resistance

Clause 15.1.2 requires parts not intended to be exposed to drainage water to be sealed before the test. Clause 31 adds a salt mist test using IEC 60068-2-52, test method 2, with a specified scratch procedure for coated enclosures. This is important for products exposed to weather and road or roof contaminants.

What terms does prEN IEC 60335-2-83:2026 define?

• Normal operation - Clause 3.1.9 defines it for this standard as operation with a thermal insulation layer covering the top surface.
• DC - The scope uses direct current (DC) to include appliances supplied from direct current sources.
• Class I - One of the appliance classes allowed by Clause 6 for these heated gullies.
• Class II - One of the appliance classes allowed by Clause 6 for these heated gullies.
• Class III - One of the appliance classes allowed by Clause 6 for these heated gullies.
• IPX7 - The minimum ingress-protection rating required by Clause 6.
• Type Z attachment - A supply arrangement permitted by Clause 25.5.
• Test probe 18 - The access probe that is not applied in Clauses 8.1.1 and 20.2, and in Annex B.

Who uses prEN IEC 60335-2-83:2026?

Manufacturers of electrically heated gullies use prEN IEC 60335-2-83:2026 to design products for flat roofs, balconies, and similar structures. Test laboratories and certification bodies use it for safety testing, including water ingress, temperature rise, mechanical strength, and corrosion checks.

It is also used by installers, specifiers, quality managers, and buyers who need to confirm that a roof-drainage heating appliance matches the required safety class, installation guidance, and outdoor-duty construction.

What changed in prEN IEC 60335-2-83:2026 from the previous edition?

This second edition cancels and replaces the first edition published in 2001 and Amendment 1:2008. The document states that it is a technical revision.

The significant technical changes listed are:

• alignment with IEC 60335-1:2020
• removal of test probe 18 from 8.1.1, 20.2, B.22.3, and B.22.4

Which standards are used with prEN IEC 60335-2-83:2026?

• IEC 60335-1 - the general household-appliance safety standard that this part 2 is used with and that supplies the common requirements.
• IEC 60068-2-52 - the salt mist test method used in Clause 31 for corrosion resistance.

What does the prEN IEC 60335-2-83:2026 document contain?

prEN IEC 60335-2-83:2026 contains clause-by-clause additions and modifications to the general safety standard, plus a normative Annex B for battery-operated appliances. It also includes a modified temperature-rise approach, special test conditions for hot and cold exposure, and a corrosion test based on IEC 60068-2-52.

For practical work, the document is used for design checks, type testing, certification, and conformity assessment of heated gullies for roof drainage. Its content is focused on the safety questions that matter most outdoors: live parts, water exposure, overheating, mechanical strength, earthing, and long-term resistance to rusting.

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, governmental and non-governmental organizations liaising
with the IEC also participate in this preparation. IEC collaborates closely with the International Organization for
Standardization (ISO) in accordance with conditions determined by agreement between the two organizations.
2) The formal decisions or agreements of IEC on technical matters express, as nearly as possible, an international
consensus of opinion on the relevant subjects since each technical committee has representation from all
interested IEC National Committees.
3) IEC Publications have the form of recommendations for international use and are accepted by IEC National
Committees in that sense. While all reasonable efforts are made to ensure that the technical content of IEC
Publications is accurate, IEC cannot be held responsible for the way in which they are used or for any
misinterpretation by any end user.
4) In order to promote international uniformity, IEC National Committees undertake to apply IEC Publications
transparently to the maximum extent possible in their national and regional publications. Any divergence between
any IEC Publication and the corresponding national or regional publication shall be clearly indicated in the latter.
5) IEC itself does not provide any attestation of conformity. Independent certification bodies provide conformity
assessment services and, in some areas, access to IEC marks of conformity. IEC is not responsible for any
services carried out by independent certification bodies.
6) All users should ensure that they have the latest edition of this publication.
7) No liability shall attach to IEC or its directors, employees, servants or agents including individual experts and
members of its technical committees and IEC National Committees for any personal injury, property damage or
other damage of any nature whatsoever, whether direct or indirect, or for costs (including legal fees) and
expenses arising out of the publication, use of, or reliance upon, this IEC Publication or any other IEC
Publications.
8) Attention is drawn to the Normative references cited in this publication. Use of the referenced publications is
indispensable for the correct application of this publication.
9) IEC draws attention to the possibility that the implementation of this document may involve the use of (a)
patent(s). IEC takes no position concerning the evidence, validity or applicability of any claimed patent rights in
respect thereof. As of the date of publication of this document, IEC had not received notice of (a) patent(s), which
may be required to implement this document. However, implementers are cautioned that this may not represent
the latest information, which may be obtained from the patent database available at https://patents.iec.ch. IEC
