National foreword

This British Standard is the UK implementation of ISO 7176‑3:2012. It supersedes BS ISO 7176‑3:2003 which is withdrawn.

The UK participation in its preparation was entrusted to Technical Committee CH/173/1, Wheelchairs.

A list of organizations represented on this committee can be obtained on request to its secretary.

This publication does not purport to include all the necessary provisions of a contract. Users are responsible for its correct application.

Compliance with a British Standard cannot confer immunity from legal obligations.

This British Standard was published under the authority of the Standards Policy and Strategy Committee on 30 April 2013.

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 7176‑3 was prepared by Technical Committee ISO/TC 173, Assistive products for persons with disability, Subcommittee SC 1, Wheelchairs.

This third edition cancels and replaces the second edition (ISO 7176‑3:2003), all clauses of which have been technically revised.

Significant technical changes from the second edition are under consideration.

ISO 7176 consists of the following parts, under the general title Wheelchairs:

Part 1: Determination of static stability
Part 2: Determination of dynamic stability of electric wheelchairs
Part 3: Determination of effectiveness of brakes
Part 4: Energy consumption of electric wheelchairs and scooters for determination of theoretical distance range
Part 5: Determination of dimensions, mass and manoeuvring space
Part 6: Determination of maximum speed, acceleration and deceleration of electric wheelchairs
Part 7: Measurement of seating and wheel dimensions
Part 8: Requirements and test methods for static, impact and fatigue strengths
Part 9: Climatic tests for electric wheelchairs
Part 10: Determination of obstacle-climbing ability of electrically powered wheelchairs
Part 11: Test dummies
Part 13: Determination of coefficient of friction of test surfaces
Part 14: Power and control systems for electrically powered wheelchairs and scooters — Requirements and test methods
Part 15: Requirements for information disclosure, documentation and labelling
Part 16: Resistance to ignition of postural support devices
Part 19: Wheeled mobility devices for use as seats in motor vehicles
Part 21: Requirements and test methods for electromagnetic compatibility of electrically powered wheelchairs and scooters, and battery chargers
Part 22: Set-up procedures
Part 25: Batteries and chargers for powered wheelchairs - Requirements and test methods
Part 26: Vocabulary
Part 28: Requirements and test methods for stair-climbing devices

Introduction

The performance of a wheelchair’s brakes can be critical for safety. The tests specified in this part of ISO 7176 determine the ability of a wheelchair to stop in a safe manner on level ground and on a slope, and determine the ability of a wheelchair to remain stationary when parked on a slope.

1 Scope

This part of ISO 7176 specifies test methods for the measurement of the effectiveness of brakes of manual wheelchairs and electrically powered wheelchairs, including scooters, intended to carry one person, with a maximum speed not exceeding 15 km/h. It also specifies disclosure requirements for the manufacturer.
