3-dimensional measurement device for chairs with integrated stability test
An increase in efficiency for testing the quality of seating furniture’s was achieved by a combination of stability testing according standard EN 1022 and a measuring station for testing of seating furniture’s according EN 1335, EN 1728 und EN 581-2.
Both tests can be performed in one single test stand consecutively, thus reducing the setting-up time. An integrated pneumatic lifting equipment allows the simple attachment of adequate loading pads conforming to standards EN 1335 und DIN 4551 with a total weight of 64 kg. Three digital measuring systems perceive the neccessary dimensions according the standard.
The distance measurement is realized by two pivoting measuring arms. The test stand is completed by the required loading pads, weights and a spring force balance. Enclosed you will find the brochure about our new test rig with picture and technical parameters. (part.-nr: 40-910-011).

The Tiltingtest according DIN 68878/1
The tilting test is of capital importance for the evaluation of the stability and durability of welded connections at tubular frames of chairs with four legs. Thus, the results of the tilting test have a direct influence on the dimension of the chair and convey a certain meaning in many companies to maintain high quality standards.
Especially for the performance of tilting tests at chairs according DIN 68878/1 we have developed a new test stand, controlled by a SPS unit, additionally containing a device, which aborts the test after specimen breakage and counts the performed cycles. The breakage of the specimen gets detected when the cylinder (actuator) deploys, but the adjusted height of stroke (normal case 3 mm) is arrived. The therefore especially developed initiator (light barrier) can be switched on and off.
A random seek of the fastening unit for the chairs at the base allows the fast and unproblematic attachment of several types of chairs. A frame construct with shock-absorbing feet and a base according DIN 68878/1 provides together with angle-adjustable pneumatic cylinders with integrated clamp-connections for the load pads the basis of the test stand. The cylinders can be positioned laterally over the entire breadth as well as in height by a crank.
The incline towards the specimen can be adjusted. Accordant the test specification a cycle time of minimum 6 seconds can be realized. If the cycle overruns 10 seconds the test will be interrupted with an error message. In order to allow the testing according standards special loading pads of 200 mm x 250 mm will be applied for the tilting test forwards and backwards, respectively, and a special prism-shaped loading pad for the tilting test sideways. As optional accessories we can deliver a weight sack and weight bags according the standards.
Please find in the appendix a prospect of our new test stand with an image and a technical description (article number 40-910-080). For further enquiries please don’t hesitate to give us a call or to send us an e-mail.
