Automatic EN1335 BIFMA X5.2 Office Chair Swivel Durability Testing Machine With LCD Touch Screen
Swivel Durability Tester is used for seating furniture, with load pad and accessories for the fixing of the chair, according to DIN 4551, EN 1335, NEN 1812 and BIFMA 5.1.
It is used for office chairs, stools, gas springs, tested units are subjected either to the entire test procedure
prescribed by the standards or to selected individual tests.
The test axes each have their own controllers assembled in the immediate vicinity, which are operated from
a Touch panel and controlled by PLC.

Build up by the control system, pneumatic system and adjust the mechanical part of composition and so on Made by aluminum frame, beautiful shape Adopt imported brand pneumatic fittings and cylinder products It can work unattended for a long time
1. Seat surface static load test
Choose corresponding test level, will load by loading pad, successively in the following two position vertically downward Add 10 times each.
-Loading templates determine the seat surface mount point
-Surface center line 100 mm from the front seat along the disadvantage
-For a specimen with two or three seats, the loading position as follows
-Two seats of the specimen, and at the same time in the template to determine two seat surface mount point and front loading point load each 10 times
-Three seat specimens, at the same time, in any side surface and the middle face templates determine the loading point and front loading points each , Load each load force 10 times at least 10 s
Bench test, load by small seat surface mat, the force on the template to determine the loading point. The end of the test and check the overall structure, sample and record, evaluation
2. Use block depends on the foot side of the chair or stool.Choose products corresponding test level, will load mat is perpendicular to the specified load through the back of the chair direction load 10 times,
Load time, load balance on the surface of the seat should be loaded into the loading templates determine the seat surface loading point, balance force size is commonly 750 n (75 kg), such as tilting the trend, the unbalanced force increase, until just stop chair tilting, and to remember, record the balance force. Loading position in the following two positions in a lower position.
- loading the template back mount point is determined
-Longitudinal axis, the back of the chair back down at the top of the 100 mm
For a specimen with two or three of the chair, according to the above regulations, loading is as follows
-Two specimens of the back of the chair, at the same time two back loading
point loading 10 times
-Three specimens of the back of the chair, on either side at the same time and in the middle of the back of the chair to load 10 times
Each loading force to keep at least 10 s
Static load should be no less than 410 n the back of the chair
Frame for rectangular stool specimen foot, regardless of seat surface shape, in turn, the force on each side with the rectangular feet adjacent points corresponding to the front of the seat along the 5 times ,Frame for triangle stool specimen foot, are in turn push force along arbitrary direction on both sides of the center 5 times of load.
End of the test, first remove the force in the back of the chair, then remove the forces acting on the surface of the present. Check the overall structure, sample and record, Evaluation.
Back of the chair, seat surface joint static load test, static load test also can be being done alone
3.Seat surface, the durability of the chair joint test
Seat surface 950 N, and then applying force of 330N on the back, with no more than 40 times/min frequency cycle ring 200000 times, then examines the specimen damage.
