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.

INTRODUCTION

Ever greater demands are now being placed on the accessibility of products, but, despite this,

there has been no easily available data for assessing and evaluating household appliances

from an accessibility perspective. An effective way to conduct product development is to work

on the basis of adequate testing methods for assessing various properties, as accessibility

recommendations can be formulated more clearly and be given greater emphasis during the

development of household and similar appliances. It is important that accessibility properties

be prioritized alongside functional, technical and production-related properties.

For this purpose, an inventory of sources with a product-accessibility focus has been drawn up,

which has given useful basic information and data for setting recommendations for the design

of household appliances. This International Standard on control elements, doors, lids, drawers

and handles is a result of this work, and provides information in the form of accessibility facts

and an understanding of the interaction of appliances and users with a wide range of abilities.

This document provides requirements, recommendations and measurements for specified

product characteristics, i.e. related to control elements, doors, lids, drawers and handles of

household and similar appliances. This contributes to their accessibility and underlying

ergonomic principles. However, products may have other aspects that are not covered in this

document, that might not be accessible. This information originates from scientific knowledge

and the theory of ergonomics, physiology, product design and other relevant disciplines. This

document applies ISO/IEC Guide 71:2014 and ISO/TR 22411:2008 to household and similar

appliances. Data is drawn from ISO/TR 22411:2008 and, if not specified there, from other

sources.

The purpose of designing and evaluating household and similar appliances with regard to

accessibility is to maximize the number of people who can readily use the products. A more

accessible product considers specific product characteristics. Such products are easier to use

and beneficial for all users. This document explains the characteristics that meet the needs and

abilities of an intended user in relation to control elements, doors, lids, drawers and handles.

ACCESSIBILITY OF CONTROL ELEMENTS,
DOORS, LIDS, DRAWERS AND HANDLES
1 Scope

This document contains accessibility requirements to enable more accessible use of certain

elements found on household and similar electrical appliances by older persons and persons

with disabilities. It provides guidance to achieve accessible design of only control elements

(e.g. knobs, buttons), including control panels, display screens and doors, lids, drawers and

handles. It does not enable the full assessment of the overall accessibility of a household

appliance. This document covers supporting and auxiliary functions that a user performs

regularly. Assembly, installation, configuration or repair of appliances are excluded.

This document provides test methods and data that support accessible design.

This document gives guidance to apply ISO/TR 22441:2008 and ISO/IEC Guide 71:2014 to the

design of various interactive elements of household and similar electrical appliances. It does

not deal with remote controls, or control via network or mobile applications. Touch control

elements are covered in this document (see also Annex A), but new interaction controls, such

as gestures and speech control, are not covered.
This document does not deal with safety issues.

NOTE IEC 60335 (all parts) sets out requirements on safety issues, e.g. surface temperatures and sharp edges.

4 Classification of control elements, doors, lids, drawers and handles
4.1 Classification of control elements
4.1.1 Rotary control elements and knobs

These include different knobs of different types, including cylindrical knobs and bar-grip knobs,

which can be seen in Figure 1. They may have discrete positions or continuous settings, or

both.
They may have a push function for confirming a selection or hiding the element.
Figure 1 – Cylindrical knobs and a bar-grip knob

A selection wheel, which can be seen in Figure 2, is a special kind of rotary control element. It

may have a push function for confirming a selection.
Figure 2 – Selection wheel
4.1.2 Slide controls
A slide control can be classified into the following categories:

• A small moveable part that slides within a groove to adjust a setting between defined start

and end points, usually along one axis (see Figure 3). They may have discrete positions or

continuous settings, or both.
EXAMPLE 1 Steam setting on a steam iron.

• A pictorial indicator or control element depicted in a graphical track that, while being

touched, can be dragged to adjust a setting between defined start and end points. The

indicator/control element can be moved in either a linear direction along one axis, or in a

circular direction. With this type of control, it is also often possible for the user to touch any

point along the graphical track to move the indicator/control element directly to this position

(setting).

4.1.3 Buttons and switches

It is the action needed to operate a button together with its interface (e.g. size and shape) that

affects its accessibility, regardless of whether the button is activated mechanically and/or

electrically. Buttons and switches can be classified into the following categories according to

the action needed:

• Latching push buttons: push buttons that latch into place, maintaining their physical state

until pressed again, when they will latch back to where they started.

• Returning push buttons: push buttons that move in the direction of the press, then move

back to their original state as the pressure is released. They may have more than one state,

for example two states turn the appliance on/off, or multiple selections for setting

temperatures.

• Countersunk buttons: like returning push buttons, but completely located within inde
