About us

Weinmann Prüftechnik has been an established player in the field of product testing technology on the international market for 30 years. As a member of the international specialist committee for standards work, the specialists at Weinmann Prüftechnik are instrumental in the development and implementation of innovative solutions from the very beginning.

The experts at Weinmann have recently constructed a Chair surveying dummy that has been binding for all international swivel chair manufacturers since the ratification of ISO standard 24496 for office swivel chairs in December 2012.

ISO CMD – survey of functional and ergonomic dimensions

“With our so-called chair measuring device (CMD) it is possible to determine the ergonomic dimensions in addition to the functional dimensions. The handling of the ISO CMD is absolutely uncomplicated. To collect the relevant results, the office swivel chair to be determined is attached to the CMD using the rig and then moved to different positions. The data is collected using relatively simple measuring instruments at the CMD. In this way, easy and uncomplicated usability is guaranteed – and the measurement takes less than half an hour, ”says Peter Weinmann, one of the two managing directors and founder of Weinmann Prüftechnik. Currently, the ISO CMD dummy is being officially considered to be adapted to the European office swivel chair standard EN 1335-1.

ISO standard 24496 mandatory since the end of 2012

In order for the current office swivel chair models to comply with the ISO standard 24496 that has been in force since December, certain measurement parameters must be observed. These can be determined with the new CMD from Weinmann. Among other things, the seat and seat height as well as the seat depth and the seat angle are to be determined. In addition, the CMD provides results for the backrest angle, the back plate height and the armrest height and width. In the same way, data about the lumbar area as well as the head and neck support area can be collected.
