Walking aids manipulated by both arms - Requirements and test methods - Part 3: Walking tables (ISO 11199-3:2005)

ISO 11199-3:2005 specifies requirements and methods of testing the static stability, braking capabilities, static strength and fatigue of walking tables without accessory equipment, unless specified in the particular test procedure. It also gives requirements relating to safety, ergonomics and performance, marking, labelling and information supplied by the manufacturer.
ISO 11199-3:2005 includes all walking tables with three or more wheels or tips against the walking surface and having arm supports in the shape of a horizontal supporting table or two horizontal forearm supports.
The requirements and tests are based on everyday usage of walking tables as walking aids, for a maximum user mass as specified by the manufacturer.
ISO 11199-3:2005 includes walking tables specified for a user mass of not less than 35 kg.

Gehhilfen für beidarmige Handhabung - Anforderungen und Prüfverfahren - Teil 3: Gehwagen (ISO 11199-3:2005)

Dieser Teil von ISO 11199 legt Anforderungen und Prüfverfahren für die Kippsicherheit, die Bremseigenschaften, die statische Festigkeit und die Materialermüdung von Gehwagen ohne zusätzliche Ausstattung fest, sofern es nicht in speziellen Prüfverfahren anders festgelegt ist.

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 2.
The main task of technical committees is to prepare International Standards. 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.
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.
ISO 11199-3 was prepared by Technical Committee ISO/TC 173, Assistive products for persons with disability.
ISO 11199 consists of the following parts, under the general title Walking aids manipulated by both arms —
Requirements and test methods:

Maximum force to apply and release parking brakes shall not exceed 60 N pushing force or 40 N pulling force.
When tested according to the parking brake test (see 5.8.3) the walking table shall not move more than
10 mm in 1 min.
Brake performance shall not be adversely affected by folding, unfolding or adjusting actions. If re-adjustment
of the brakes is necessary following an adjusting action of the walking table (e.g. height adjustment), tools
shall not be required.
4.3 Mechanical durability
When tested according to the static strength test (see 5.10) no part of the walking table shall crack or break
and the permanent set of the walking table height shall not exceed 1 %.
When tested according to the fatigue test (see 5.11) no part of the walking table shall crack or break.
4.4 Manoeuvrability
The wheel diameter shall be not less than 75 mm.
The wheel diameter of walking tables manufactured for outdoor use shall be not less than 180 mm.
The wheel width of walking tables manufactured for outdoor use shall be not less than 22 mm as defined

The handgrip shall be securely fixed to the handle of the walking table as judged by the inspector.
The handgrip shall be replaceable or easy to clean.
4.6 Leg section and tip
Where there is no wheel, the leg section shall end in a tip of a design that will prevent the leg section from
piercing it when the walking table is used as intended by the manufacturer.
Where there is no wheel, the tip shall be replaceable.
Where there is no wheel, the tip shall not cause discolouring of the walking surface, as verified by visual
inspection.
That part of the tip that is in contact with the walking surface shall have a minimum area at least covering a
circle of diameter 35 mm. Compliance shall be verified by measurement.
When inspected, the rubber tip shall be securely fixed to the leg of the walking table as judged by the
inspector.

4.7 Adjusting devices
The handles may be adjustable but shall be securely fixed when in use, as verified by inspection.
Each of the height adjustment devices shall be clearly marked with its maximum permissible elongation.
After the fatigue test (see 5.11), the adjustment/folding mechanisms shall operate as intended by the
manufacturer.
Folding walking tables shall lock into working position when unfolded.
4.8 Resting seat
When tested according to 5.9, no part of the walking table shall crack or break.
4.9 Materials and finish
Walking table materials, which come into contact with the human body during intended use, handling,
transportation and storage, shall be assessed for bio-compatibility using the guidance given in ISO 10993-1.
The walking table materials shall not cause discolouring of skin or clothing when the walking table is used as
intended by the manufacturer.
All parts of the walking table shall be free from burrs, sharp edges or projections that could cause damage to
clothing or discomfort to the user and attendant.
4.10 Marking and labelling
User information shall be provided according to Clause 6.
5 Test methods
5.1 General
All tests, if not otherwise specified, shall be performed at an ambient temperature of 21 °C ± 5 °C.
If not otherwise specified, all tests shall be performed with the height adjustments at their maximum and
swivelling wheels in the least stable position. The handles shall be positioned as far forward as the fastening
mechanism is intended. Width-adjustable supporting tables shall be set at maximum width. If adjustable, each
forearm support shall be adjusted to the position giving minimum stability, as judged by the testing personnel
and at the same time angled inwards at the front as close as possible to 10° in relation to the centreline of the
aid in the direction of walking. The angle shall always be recorded.
Parking or running brakes shall not be activated unless specified in the test procedure.
During the stability tests, the wheels shall be in the most unstable position for the test being performed, and
the walking table shall be prevented from sliding or rolling before tilting occurs. The results of the tests shall
not be influenced by the means used.
If the manufacturer offers alternate fittings as accessory equipment, all alternatives shall be supplied with the
walking table when tested so that the walking table may be tested in the least favourable configuration (e.g.
with extended handles).
