Overview

IEC 60335-2-48:2000 is the IEC safety standard that specifies particular requirements for commercial electric grillers and toasters (rotary, continuous and radiant‑heat types such as rotisseries and salamanders). It is Part 2-48 of the IEC 60335 series and is to be used in conjunction with the latest edition of IEC 60335-1 (general safety for household and similar electrical appliances). The standard applies to appliances not intended for household use (e.g., restaurants, canteens, bakeries, butcheries) and covers electrical parts of appliances that may otherwise use other energy sources.

Key scope points:

• Rated voltage: ≤ 250 V for single‑phase (phase to neutral) and ≤ 480 V for other appliances.
• Includes rotary/continuous grillers and toasters and appliances using radiant heat.
• Excludes appliances designed exclusively for industrial process, griddles (covered by IEC 60335-2-38), continuous mass‑production equipment, or use in corrosive/explosive atmospheres without additional measures.

Key topics and technical requirements

The standard supplements and modifies IEC 60335-1 with particular requirements specific to commercial grillers and toasters. Major technical topics include:

• Classification and protection: appliances are normally Class I for protection against electric shock (earthing provisions required).
• Marking and instructions: mandatory instructions for installation (banks of appliances, fixed wiring), water‑pressure marking for water‑connected units, and warnings about cleaning (e.g., prohibition of water jets where applicable).
• Testing conditions: appliances tested as heating appliances; normal operation, moisture resistance, leakage current and dielectric strength tests, endurance and abnormal‑operation tests.
• Construction and safety aspects: stability/mechanical hazards, mechanical strength, internal wiring, components, terminals, creepage/clearance, resistance to heat/fire/tracking, and radiation/toxicity considerations.
• Installation considerations: requirements for appliances fixed to installation walls or installed in banks, and instructions where leakage currents may exceed 10 mA (recommendation for earth leakage protective devices).

FOREWORD
1) The IEC (International Electrotechnical Commission) is a worldwide organization for standardization comprising
all national electrotechnical committees (IEC National Committees). The object of the 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, the IEC publishes International Standards. 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. The 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 the 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 National Committees.
3) The documents produced have the form of recommendations for international use and are published in the form
of standards, technical specifications, technical reports or guides and they are accepted by the National
Committees in that sense.
4) In order to promote international unification, IEC National Committees undertake to apply IEC International
Standards transparently to the maximum extent possible in their national and regional standards. Any
divergence between the IEC Standard and the corresponding national or regional standard shall be clearly
indicated in the latter.
5) The IEC provides no marking procedure to indicate its approval and cannot be rendered responsible for any
equipment declared to be in conformity with one of its standards.
6) Attention is drawn to the possibility that some of the elements of this International Standard may be the subject
of patent rights. The IEC shall not be held responsible for identifying any or all such patent rights.
International Standard IEC 60335-2-48 has been prepared by subcommittee 61E: Safety of
electrical commercial catering equipment, of IEC technical committee 61: Safety of household
and similar electrical appliances.
It forms the third edition of IEC 60335-2-48 and replaces the second edition, published in 1995,
