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.
International Standards are drafted in accordance with the rules given in the ISO/IEC Directives, Part 3.
Draft International Standards adopted by the technical committees are circulated to the member bodies for voting.
Publication as an International Standard requires approval by at least 75 % of the member bodies casting a vote.
International Standard ISO 11199-1 was prepared by Technical Committee ISO/TC 173, Technical systems and
aids for disabled or handicapped persons.
ISO 11199 consists of the following parts, under the general title Walking aids manipulated by both arms —
Requirements and test methods:
 Part 1: Walking frames
 Part 2: Rollators
Annex A of this part of ISO 11199 is for information only.

Walking aids manipulated by both arms — Requirements and test
methods —
Part 1:
Walking frames
1 Scope
This part of ISO 11199 specifies requirements and methods of testing fatigue, static load capacity and stability of
walking frames without accessories, unless specified in the particular test procedure. This part of ISO 11199 also
gives the requirements relating to safety, ergonomics, performance, marking and labelling.
The requirements and tests are based on everyday usage of walking frames manufactured for a user mass of not
less than 35 kg.
NOTE Recommendations further to the requirements given in this part of ISO 11199 are given in annex A.
2 Normative references
The following normative documents contain provisions which, through reference in this text, constitute provisions of
this part of ISO 11199. For dated references, subsequent amendments to, or revisions of, any of these publications
do not apply. However, parties to agreements based on this part of ISO 11199 are encouraged to investigate the
possibility of applying the most recent editions of the normative documents indicated below. For undated
references, the latest edition of the normative document referred to applies. Members of ISO and IEC maintain
registers of currently valid International Standards.

3 Terms and definitions
For the purposes of this part of ISO 11199, the following terms and definitions apply (see also Figures 1, 2 and 3).
3.1
folded dimensions
height, width and length of the walking frame measured with the frame folded together without the use of tools, the
height adjustment at its minimum height and the handles positioned as in 5.1.
3.2
frame height
vertical distance from the rear handgrip reference point to the ground
See Figure 3.

3.3
front handgrip reference point
that point on the upper surface of the handgrip located 30 mm from the front end of the handgrip length
See Figure 2.
3.4
handgrip
that part of the walking frame which is normally held by the hand when the frame is in use
3.5
handgrip length
dimension of the handgrip measured longitudinally where the hand rests
See Figure 2.
NOTE Where the front end or the rear end of the handgrip is not clear, the full length of the handgrip that can support the
weight of the user is defined as the handgrip length.
3.6
handgrip width
outside dimension of the handgrip measured horizontally at the thickest point where the hand rests
See Figure 2.
3.7
handle
that part of the walking frame to which the handgrip is attached.
3.8
maximum length
maximum outside dimension of a walking frame when the height adjustment is at its maximum, measured parallel to
the direction of movement when the frame is in normal use
See Figure 3.
3.9
maximum width
maximum outside dimension of a walking frame when the height adjustment is at its maximum, measured
horizontally at right angles to the direction of movement when the frame is in normal use
See Figure 3.
3.10
rear handgrip reference point
that point on the upper surface of the handgrip located 30 mm from the rear end of the handgrip length
See Figure 2.
NOTE If the grip protrudes further than the handle, the measurement is made from the end of the handle.
3.11
tip
that part of a walking frame which is in contact with the ground
3.12
turning diameter
diameter of the largest circle described by a walking frame when the height adjustment is at its maximum and the
walking frame is turned through 360° about its own central vertical axis
See Figure 3.

user weight
body mass of the person using the product as a technical aid
NOTE Standard user weight is 100 kg for adults and 35 kg for children.

walking frame
walking aid without wheels and with no support devices other than handles

4 Requirements
4.1 Mechanical durability
When tested according to the fatigue test (5.3), no part of the walking frame shall crack or break.
When tested according to the static loading test (5.4), no part of the frame shall crack or break.
When tested according to the static leg-strength test (5.5), none of the legs shall crack, break or show any
permanent set of more than 15 mm, measured at the end of the leg.
4.2 Stability
When tested according to the forward stability test (5.6), the angle of the plane at the point of walking frame tilting
shall be not less than 10,0°.
When tested according to the backward stability test (5.7), the angle of the plane at the point of walking frame tilting
shall be not less than 7,0°.
When tested according to the sideways stability test (5.8), the angle of the plane at the point of walking frame tilting
shall be not less than 3,5°.
It is acknowledged that a reciprocal walking frame cannot meet this sideways stability requirement. Therefore, an
analysis of the risks related to the instability shall be assessed by the manufacturer, and appropriate guidance and
warnings on limitations for use shall be given.
