Foreword

ISO (the International Organization for Standardization) is a worldwide federation of national standards

bodies (ISO member bodies). The work of preparing International Standards is normally carried out

through ISO technical committees. Each member body interested in a subject for which a technical

committee has been established has the right to be represented on that committee. International

organizations, governmental and non-governmental, in liaison with ISO, also take part in the work.

ISO collaborates closely with the International Electrotechnical Commission (IEC) on all matters of

electrotechnical standardization.

The procedures used to develop this document and those intended for its further maintenance are

described in the ISO/IEC Directives, Part 1. In particular, the different approval criteria needed for the

different types of ISO documents should be noted. This document was drafted in accordance with the

editorial rules of the ISO/IEC Directives, Part 2 (see www .iso .org/ directives).

Attention is drawn to the possibility that some of the elements of this document may be the subject of

patent rights. ISO shall not be held responsible for identifying any or all such patent rights. Details of

any patent rights identified during the development of the document will be in the Introduction and/or

on the ISO list of patent declarations received (see www .iso .org/ patents).

Any trade name used in this document is information given for the convenience of users and does not

constitute an endorsement.

For an explanation of the voluntary nature of standards, the meaning of ISO specific terms and

expressions related to conformity assessment, as well as information about ISO's adherence to the

World Trade Organization (WTO) principles in the Technical Barriers to Trade (TBT), see www .iso .org/

This document was prepared by Technical Committee ISO/TC 173, Assistive products, in collaboration

with the European Committee for Standardization (CEN) Technical Committee CEN/TC 293, Assistive

products and accessibility, in accordance with the Agreement on technical cooperation between ISO and

CEN (Vienna Agreement).

This second edition cancels and replaces the first edition (ISO 11199-1:1999), which has been technically

revised.
The main changes compared to the previous edition are as follows:
— 3.1 was changed to be in accordance with ISO 9999;

— Clause 6, on general requirements for assistive products for walking, was added.

A list of all parts in the ISO 11199 series can be found on the ISO website.

Introduction

A walking frame can be used when a person needs assistance when walking. The walking frame can

provide stability when walking and standing and reduce the risk of falling. Walking frames are designed

to support the user inside a frame to carry the user’s full body weight.

Part 1:
Walking frames
1 Scope

This document specifies requirements and test methods for walking frames used as assistive products

for walking, manipulated by both arms, without accessories, unless specified in the particular test

procedure. This document also gives requirements relating to safety, ergonomics, performance and

information supplied by the manufacturer, including marking and labelling.

The requirements and tests are based on everyday use of walking frames as assistive products for

walking for a maximum user mass as specified by the manufacturer. This document includes walking

frames specified for a user mass of no less than 35 kg.

Foreword

ISO (the International Organization for Standardization) is a worldwide federation of national standards

bodies (ISO member bodies). The work of preparing International Standards is normally carried out

through ISO technical committees. Each member body interested in a subject for which a technical

committee has been established has the right to be represented on that committee. International

organizations, governmental and non-governmental, in liaison with ISO, also take part in the work.

ISO collaborates closely with the International Electrotechnical Commission (IEC) on all matters of

electrotechnical standardization.

The procedures used to develop this document and those intended for its further maintenance are

described in the ISO/IEC Directives, Part 1. In particular, the different approval criteria needed for the

different types of ISO documents should be noted. This document was drafted in accordance with the

editorial rules of the ISO/IEC Directives, Part 2 (see www .iso .org/ directives).

Attention is drawn to the possibility that some of the elements of this document may be the subject of

patent rights. ISO shall not be held responsible for identifying any or all such patent rights. Details of

any patent rights identified during the development of the document will be in the Introduction and/or

on the ISO list of patent declarations received (see www .iso .org/ patents).

Any trade name used in this document is information given for the convenience of users and does not

constitute an endorsement.

For an explanation of the voluntary nature of standards, the meaning of ISO specific terms and

expressions related to conformity assessment, as well as information about ISO's adherence to the

World Trade Organization (WTO) principles in the Technical Barriers to Trade (TBT), see www .iso .org/

This document was prepared by Technical Committee 173, Assistive products for persons with

disability.

This second edition cancels and replaces the first edition (ISO 11199-1:1999), which has been technically

revised.
The main changes compared to the previous edition are as follows:

— corrected the definition of Walking frames to conform to the definition described in ISO 9999:2016

(classification no.: 12 06 03)

— added the clauses for relevant general requirements for assistive products for walking based upon

ISO/DIS 21856, ISO 17966, and EN12182

Assistive products for walking manipulated by both arms are covered by the following International

Standards:
— ISO 11199-Part 1: Walking frames
— ISO 11199-Part 2: Rollators
— ISO 11199-Part 3: Walking tables
— ISO 19894: Walking trolleys

Introduction

A walking frame, as defined in ISO 11199-1 can be used when a person needs assistance when walking.

The walking frame can provide stability when walking and standing and reduce the risk of falling.

Walking Frames are designed to support the user inside a frame to carry the user’s full body weight. In

addition to the requirements in this international standard, Annex B gives general recommendations

Part 1:
Walking frames
1 Scope

This part of ISO 11199 specifies requirements and test methods of walking frames being used as

assistive products for walking, manipulated by both arms, without accessories, unless specified in the

particular test procedure. This part of ISO 11199 also gives requirements relating to safety, ergonomics,

performance and information supplied by the manufacturer including marking and labelling.

The requirements and tests are based on every-day use of walking frames as assistive products for

walking for a maximum user mass as specified by the manufacturer. This part of ISO 11199 includes

walking frames specified for a user mass of no less than 35 kg.
