ISO 16840-3:2006 specifies test methods for the determination of static, impact and repetitive load strengths as well as disclosure requirements for postural support devices (PSD) with associated attachment hardware intended for use with wheelchairs.
ISO 16840-3:2006 does not test the transportability and the use of the PSD in a motor vehicle.
NOTE At the present time there are no minimum or maximum strength requirements specified in the test procedures for testing for PSDs. In the future, minimum or maximum loads for testing might be specified for testing on a pass/fail basis. The maximum displacement, the maximum force achieved before failure and the type of failure that occurs is disclosed for comparison purposes.
