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.

The procedures used to develop this document and those intended for its further maintenance are described in the ISO/IEC Directives, Part 1. In particular the different approval criteria needed for the different types of ISO documents should be noted. This document was drafted in accordance with the editorial rules of the ISO/IEC Directives, Part 2 (see www.iso.org/directives).

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. Details of any patent rights identified during the development of the document will be in the Introduction and/or on the ISO list of patent declarations received (see www.iso.org/patents).

The committee responsible for this document is ISO/TC 173, Assistive products for persons with disability, Subcommittee SC 1, Wheelchairs.

ISO 16840 consists of the following parts, under the general title Wheelchair seating:

— Part 1: Vocabulary, reference axis convention and measures for body segments, posture and postural support surfaces
— Part 2: Determination of physical and mechanical characteristics of devices intended to manage tissue integrity — Seat cushions
— Part 3: Determination of static, impact and repetitive load strengths for postural support devices
— Part 4: Seating systems for use in motor vehicles
— Part 6: Simulated use and determination of the changes in properties of seat cushions
— Part 9: Clinical interface pressure mapping guidelines for seating [Technical Report]
— Part 10: Resistance to ignition of non-integrated seat and back support cushions — Part 10: Requirements and test methods
— Part 11: Determination of perspiration dissipation characteristics of seat cushions intended to manage tissue integrity [Technical Specification]
— Part 12: Apparatus and method for cushion envelopment testing [Technical Specification]

Future parts dealing with methods for determining heat and water vapour characteristics and clinical guidelines for the measurement of postural support surfaces and body segments are planned.
