Wheelchair seating - Part 3 : determination of static, impact, and repetitive load strengths for postural support devices

This document specifies requirements for static, impact, and repetitive load strengths for postural support devices (PSDs) with associated attachment hardware intended for use with an undefined wheelchair seating system. It specifies the test methods for determining whether the minimum performance requirements have been met to release a product into use. It also specifies requirements for disclosure of the test results. Not all tests apply to all PSDs.This document is also applicable to other seating systems.The test methods can be used to verify the manufacturer’s claims that a product meets the requirements of this document. This document does not apply to PSDs that are designed to fail under certain static, dynamic, or repetitive loads.This document does not apply to the strength of PSDs under crash conditions in a motor vehicle.This document does not evaluate long-term useful life.NOTE 1   ISO 16840‑4 provides crash test methods and requirements for wheelchair seating systems when used as part of a wheelchair seat in a motor vehicle.NOTE 2   For user masses greater or less than those specified in this document, appropriate extrapolation of test apparatus dimensions, mounting point separation, forces, etc. can be carried out, and the test parameters noted in the test report.NOTE 3   Rigid surrogate test fixtures are utilized to provide a standardized test method, and consequently this document does not involve a test of a PSD on a particular wheelchair.

Wheelchair seating - Part 3 : determination of static, impact, and repetitive load strengths for postural support devices

This document specifies requirements for static, impact, and repetitive load strengths for postural support devices (PSDs) with associated attachment hardware intended for use with an undefined wheelchair seating system. It specifies the test methods for determining whether the minimum performance requirements have been met to release a product into use. It also specifies requirements for disclosure of the test results. Not all tests apply to all PSDs.

This document is also applicable to other seating systems.

The test methods can be used to verify the manufacturer’s claims that a product meets the requirements of this document. This document does not apply to PSDs that are designed to fail under certain static, dynamic, or repetitive loads.

This document does not apply to the strength of PSDs under crash conditions in a motor vehicle.

This document does not evaluate long-term useful life.

NOTE 1   ISO 16840‑4 provides crash test methods and requirements for wheelchair seating systems when used as part of a wheelchair seat in a motor vehicle.

NOTE 2   For user masses greater or less than those specified in this document, appropriate extrapolation of test apparatus dimensions, mounting point separation, forces, etc. can be carried out, and the test parameters noted in the test report.

NOTE 3   Rigid surrogate test fixtures are utilized to provide a standardized test method, and consequently this document does not involve a test of a PSD on a particular wheelchair.

ZOOM ON ... the Requirements department
To comply with a standard, you need to quickly understand its issues in order to determine its impact on your activity.

The Requirements department helps you quickly locate within the normative text:
- mandatory clauses to satisfy,
- non-essential but useful clauses to know, such as permissions and recommendations.

The identification of these types of clauses is based on the document “ISO / IEC Directives, Part 2 - Principles and rules of structure and drafting of ISO documents ”as well as on a constantly enriched list of verbal forms.
