ELECTRIC IRONS FOR HOUSEHOLD
OR SIMILAR USE –
METHODS FOR MEASURING PERFORMANCE
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 60311 has been prepared by subcommittee 59E: Ironing and

pressing appliances, of IEC technical committee 59: Performance of household electrical

appliances.

This fourth edition of IEC 60311 cancels and replaces the third edition published in 1995 and

its amendment 1 (1997) and amendment 2 (1999).

The text of this standard is based on the third edition, amendments 1 and 2 and the following

documents:

ELECTRIC IRONS FOR HOUSEHOLD
OR SIMILAR USE –
METHODS FOR MEASURING PERFORMANCE
1 Scope

This International Standard applies to electric irons for household or similar use.

The purpose of this standard is to state and define the principal performance characteristics

of electric irons for household or similar use which are of interest to the user and to describe

the standard methods for measuring these characteristics.
Electric irons covered by this standard include
− dry irons;
− steam irons;
− spray irons;

− steam irons with separate water reservoir or boiler/generator having a capacity not

exceeding 5 l.

This standard is concerned neither with safety nor with performance requirements.

NOTE The primary characteristic to be taken into account in assessing the performance of an electric iron is its

basic ability to produce a smooth finish to textile materials, without risk of scorching or other damage. lt has not

proved possible to devise a single method which will measure this characteristic in a consistently reproducible way

and measurements have therefore been included to check certain factors, such as the temperature of the sole-

plate at the mid-point, sole-plate temperature distribution, etc., which affect the basic characteristic. In evaluating

the results, it must be realized that, while a very exceptional result in any one of them may significantly affect

performance, there is considerable latitude in the combination of results which will give satisfactory ironing

performance, and too much significance should not be attached to minor differences in any one result.
