TNJ-017 Seat Endurance Tester--Office Chair Seat and Backrest
Strength and Durability Tester
Purpose: This test apparatus is used for the strength and durability
performance test for office chairs, including seating load test,
backrest load test and seat & back combined test.
Principle: This test apparatus do the durability test to chair seat and
backrest by simulating the loading application to the chair as
daily use and habit misuse. First use the seat loading pad to apply
the certain loading to the seat surface, then the back loading pad
to the backrest, then loading unload to finish one cycle of test,
repeat the loading movement some times and certain cycles according
to different test requirement, to determine the durability
performance of chairs.
Description:
Office Chair Seat Back durability tester is used for testing the
strength and durability of office chair. Made of Aluminum material
frame, PLC control, easy operation; high precision force sensor for the load
application.
Seat and chair back durability combined tester.
Test Items:
Seat and back Static load test: test consisting of heavy loads being applied a few times to ensure
that furniture has sufficient strength under the highest levels of
loading that might reasonably be expected to occur.
Seat and back Fatigue test: Test simulating the repeated application of loads or movement of
components occurring during long-term functional use.
This test apparatus do the durability test to chair seat and
backrest by simulating the loading application to the chair as
daily use. First use the seat loading pad to apply the certain
loading to the seat surface, then the back loading pad to the
backrest, then loading unload to finish one cycle of test, repeat
the loading movement some times and certain cycles according to
different test requirement, to determine the durability performance
of chairs.
Pneumatic drive to load, easy to clean.
