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 11199-2 was prepared by Technical Committee ISO/TC 173, Assistive products for persons with disability.
This second edition cancels and replaces the first edition (ISO 11199-2:1999), which has been technically
revised.
ISO 11199 consists of the following parts, under the general title Walking aids manipulated by both arms —
Requirements and test methods:

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.
Swivelling wheels shall be positioned as if the rollator is run forward, if not otherwise stated. The handles shall
be positioned at their maximum distance and maximum angles in the horizontal plane relative to the direction
of motion as specified by the manufacturer. When the longitudinal centreline of the handle and the direction of
forward motion are parallel, the angle is 0°. The angle shall always be recorded.
During the stability tests, the rollator 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 rollator is less stable with the height adjustment
at a lower height, the least stable position shall be tested.
Parking or running brakes shall not be activated unless specified in the test procedure.
If the manufacturer offers alternative handle fittings as accessory equipment, all alternatives shall be supplied
with the rollator when tested so that the rollator may be tested in the least favourable configuration (e.g.
extended handles).
5.2 Sampling and inspection
One rollator shall be tested. The sequence of tests shall be as follows:
 measurements;
 stability;
 brakes;
 handgrips;
 rubber tips;
 static loading of resting seat;

SIST EN ISO 11199-2:2005
ISO 11199-2:2005(E)
 static loading of handles;
 fatigue.
Immediately before being tested, the rollator shall be inspected to check compliance with this part of
ISO 11199. Any apparent defects shall be noted so that they shall not later be recorded as having been
caused by the tests.
5.3 Forward-direction stability test
5.3.1 Loading geometry
Height adjustment and handles shall be positioned as specified in 5.1. Swivelling wheels shall be in the least
stable position.
The rollator shall be placed with its wheels and/or tips on a plane that can be tilted from the horizontal with the
centreline of the hinges parallel to the line through the axis of the front wheels, and at right angles to the
normal direction of movement when the rollator is in use (see Figure 7). The loading force shall be applied
vertically to the rollator. The loading line shall remain vertical and pass through the midpoint of the line joining
the front handgrip reference points on the two handgrips.
5.3.2 Procedure
A static force of 250 N ± 2 % shall be applied. The plane shall be tilted and the maximum angle of the plane at
the point of rollator tilting recorded. Accuracy of measurement shall be less than or equal to ± 0,5°.
