Chair Seating Impact and Durability Testing Machine

Short Description:

This chair seating impact and durability testing machine is a multi-function test bench for seating products, including office chairs, chairs, plastic chairs and stools. It performs two test modes — repeated seat impact and single (one-time) seat impact — to evaluate the durability of the seat surface under vertical force, simulating an abusive sitting load far beyond normal use.

product advantages

Two Test Modes in One Bench – Switches between repeated seat impact and single one-time impact, covering durability and peak-load requirements on the same platform.
True Free-Fall Release – An electromagnet holds and releases the impact head, so the mass falls without cylinder drag, matching the free-fall condition the standards assume.
Unconstrained Vertical Loading – Foot-cup lateral restraints fix the chair horizontally while leaving the seat free vertically, preventing false passes from over-constrained specimens.
250 mm Drop, 125–500 lbs Load – The full impact weight range is adjustable, covering BIFMA X5.1 and EN 1335 impact energy levels without fixture changes.
Power-Failure Memory – The touchscreen controller logs impact count and speed continuously and resumes the test after a power interruption, protecting long-run durability cycles.
Low-Noise Hydraulic Buffering – A hydraulic buffer on the return stroke reduces noise and mechanical wear, keeping the bench suitable for lab and production-floor use.
