Chair-Back-Durability-Test
Application This test shall be performed on Type I Tilting chairs with backrests greater than 200 mm in height. It is used for static load and durability tests of various office
chairs, high chairs, children's dining chairs, etc., to simulate
the user's condition, and to perform cushions and backrests
(simultaneous and/or separate) for all kinds of chairs. Static load
test and dynamic endurance test to judge the fatigue stress and
bearing capacity of the test piece Product introduction Chair back durability test equipment tests the strength and durability of the seats and backrests by simulating the daily use loading of the seat. The machine is equipped with two drive devices, which can be individually controlled to repeatedly load the test points of the seat. Through different parameter settings, the machine can do following test on the seat: 1. Seat and back static load test. 2. Seat and back durability test. 3. Seat front edge static load and durability test; 4. Horizontal forward static loading test for backrest. 5. Headrest static load test, 6. Legs forward static load test, 7. Legs lateral static load test. Technical parameter a.One pneumatic cylinder with load cell capacity 200N. b.Adjustable load direction (90° to the chair backrest) c.Form-fitting load distribution device: A device which distributes
a force over a 305 ± 13mm ×70 ± 32mm(12±0.5'' ×2.75'' ± 1.25'')
area of a backrest. The device will be shaped to approximate the
contours of the chair backrest (refer attachment) d.2 operation mode: -Electronic predetermined counter(EPC) - 6 digit counter to
stroke the cylinder up to 120.000 cycles. -Timer - to apply and release the force after 1 minute. Compressed air: ± 6kg/m² e.Single phase AC 220V f.Speed: adjutable (10-30 cycle/minute) g.Clamp:- to restrain the chair base. i.Backrest strength test-Static -Type I & II (ANSI/BIFMA X5.1-2017, clause 5) ii.Backrest strength test-Static -Type III (ANSI/BIFMA X5.1-2017, clause 6) iii.Backrest durability test - cyclic - Tpye I &II (ANSI/BIFMA X5.1-2017, clause 14) IV.Backrest durability test - cyclic - Tpye III (ANSI/BIFMA X5.1-2017, clause 15) Specification
