Full title and description

St ISO 7176-11-2012 — Wheelchairs — Part 11: Test dummies. Specifies requirements and construction details for anthropomorphic test dummies used in the evaluation of manual and electrically powered wheelchairs (including scooters), providing formulas and data so that dummies of various masses produce comparable results in stability, performance and durability testing.

Abstract

ISO 7176-11:2012 defines test-dummy requirements for masses ≥ 25 kg, gives formulae for overall centre of mass, segment masses and pivot locations, and specifies characteristics of loading pads that support dummy segments. It also includes informative tables of segment masses and centre-of-mass locations for example dummy masses up to 300 kg in 25 kg increments to support reproducible test results across laboratories and manufacturers.

Scope

Specifies the constructional and mass-distribution requirements for test dummies intended for use in other parts of ISO 7176 so that stability, performance and durability tests on wheelchairs and scooters are comparable. The standard covers formulae for overall centre of mass, segment masses, pivot locations and loading-pad characteristics, and provides example tables for dummy masses from 25 kg up to 300 kg in 25 kg steps.

Key topics and requirements

• Definition of nominal dummy mass classes (≥ 25 kg) and corresponding segment mass distributions.
• Formulae to determine overall centre of mass and positions of segment centres of mass.
• Location of pivots connecting dummy segments to reproduce realistic posture and load transfer.
• Characteristics and placement of loading pads that contact wheelchair seating and supports.
• Informative tables of masses and centres of mass up to 300 kg in 25 kg increments for example constructions.
• Designed to produce comparable outcomes for stability, performance and durability tests across test labs and manufacturers.

Typical use and users

Used by wheelchair and scooter manufacturers, independent testing laboratories, conformity assessment bodies, regulatory authorities, product designers and researchers conducting stability, durability and performance tests on manual and powered wheelchairs. It is applied whenever reproducible anthropometric loading conditions are needed for ISO 7176 test methods.

Related standards

Part of the ISO 7176 series (wheelchairs), commonly used alongside other parts such as ISO 7176-1, -4, -5, -6, -7, -8, -9, -10, -13, -15, -20, -22 and -26 (test methods and requirements for dimensions, strength, performance, environmental tests, set-up procedures and terminology). Users typically apply ISO 7176-11 together with the specific test-method part that requires a test dummy.

FAQ

Q: What is this standard?

A: ISO 7176-11:2012 is the ISO international standard that specifies constructional and mass-distribution requirements for test dummies used in wheelchair evaluation (Edition 2, published December 2012).

Q: What does it cover?

A: It covers formulae and requirements to determine overall centre of mass, segment masses and pivot locations for test dummies, characteristics of loading pads, and provides informative tables for example dummy masses (25 kg to 300 kg) so tests across labs and manufacturers are comparable.

Q: Who typically uses it?

A: Wheelchair and scooter manufacturers, test houses, regulatory and conformity-assessment bodies, researchers and product designers who need reproducible anthropomorphic loading in performance, stability and durability tests.

Q: Is it current or superseded?

A: ISO 7176-11:2012 is the current published edition that replaced ISO 7176-11:1992 (the 1992 edition was withdrawn when the 2012 second edition was published). ISO standards are subject to periodic review (typically every five years); users should check the ISO catalogue for the latest review status if precise currency is required.

Q: Is it part of a series?

A: Yes — it is part of the ISO 7176 series addressing wheelchairs. ISO 7176-11 supplies the test-dummy definitions used by other parts of the series that specify particular test methods and requirements.

Q: What are the key keywords?

A: Test dummy, manikin, centre of mass, segment mass, loading pad, wheelchair testing, stability, durability, ISO 7176.
