Tips for assistive products for walking -- Requirements and test methods
ISO 24415-2:2011 specifies requirements and test methods for the durability of tips for crutches. ISO 24415-2:2011 is not applicable to tips manufactured for special purposes e.g. walking on ice and snow. The requirements and test method are based on tips being used with an ordinary gait on dry and flat walking surfaces.

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

ISO 24415-2 was prepared by Technical Committee ISO/TC 173, Assistive products for persons with disability.
ISO 24415 consists of the following parts, under the general title Tips for assistive products for walking —Requirements and test methods:
— Part 1: Friction of tips
— Part 2: Durability of tips for crutches

The characteristics of tips attached to the bottom of assistive products for walking are essential to ensuring
user safety. The tips are continuously and repeatedly subjected to load and friction while walking; durability
against this repeated load is important both for safety and for cost effectiveness.
Tips are used on many different assistive products for walking, including canes, walking sticks, crutches,
walking frames, rollators, and walking tables. They are produced in many different sizes and are made of many
different materials, depending on the sort of assistive products for walking to which they are applied. A variety
of bottom shapes are available on the market for the many kinds of assistive products for walking.
Generally, durability of rubber is estimated based on a wearing resistance test using test pieces rather than
finished goods. However, tips for assistive products for walking are used in several different ways, therefore it
is favourable to perform the test on manufactured tips (not manufactured test pieces) to obtain realistic data.
For example, tips for crutches can endure less abrasion, because the load on tips for crutches is higher thanthat on tips for other assistive products for walking.
This part of ISO 24415 specifies requirements and test methods for durability of tips for crutches to enable developers,
manufacturers, distributors, and health care providers to determine whether tips have the necessary durability.iv © ISO 2011 – All rights reserved

INTERNATIONAL STANDARD ISO 24415-2:2011(E)
Tips for assistive products for walking — Requirements and
test methods —
Durability of tips for crutches
This part of ISO 24415 specifies requirements and test methods for the durability of tips for crutches, and is
not applicable to tips manufactured for special purposes. The requirements and test method are based on tipsbeing used with an ordinary gait on dry and flat walking surfaces.
Crutches include elbow crutches, forearm support crutches, and axillary crutches, as described in ISO 9999.NOTE Special purposes might include walking on ice and/or snow.
