ELECTRIC IRONS FOR HOUSEHOLD OR SIMILAR USE –
METHODS FOR MEASURING PERFORMANCE
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) Attention is drawn to the possibility that some of the elements of this IEC Publication may be the subject of

patent rights. IEC shall not be held responsible for identifying any or all such patent rights.

International Standard IEC 60311 has been prepared by subcommittee 59L: Small household

appliance, of IEC technical committee 59: Performance of household and similar electrical

appliances.

This fifth edition cancels and replaces the fourth edition published in 2002, Amendment

1:2005 and Amendment 2:2009. This edition constitutes a technical revision.

This edition includes the following significant technical changes with respect to the previous

edition:

a) 5.3: introduction of clarifications on voltage and frequency to be applied for the tests;

b) 5.12: introduction of an anti-circumvention subclause;
c) 9.2.3: clarification on the procedure for measuring steaming rate;
d) 14.1 and 14.2: clarification on type of water used for the tests;
e) Figure 2: clarifications and alignment with the relevant formula.

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 document 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;
• vented steam irons with motor pump;
• spray irons;

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

exceeding 5 l.

This document 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, 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 is not given to minor differences in any one result.
