Frequently Asked Questions

Q: What is this equipment used for?
This tester evaluates the durability and structural strength of chairs, stools, and other seating by simulating repeated loading on the seat and backrest. It helps manufacturers ensure products withstand long-term use without failure.

Q: How does it work?
Pneumatic actuators apply controlled, repeatable forces to the seat and backrest at programmable speeds and cycle counts. The PLC controller manages the test sequence, while a load cell with PID feedback maintains precise force application.

Q: What standards does it comply with?
It supports EN 1728, ISO 7173, BS EN 1335-3, BS EN 581-2, GB/T 10357.3, QB/T 2280, and BIFMA X5.1. This makes it suitable for testing to both European and American seating standards.

Q: What types of chairs can be tested?
Office chairs, work seating, stools, and various other seating furniture. The adjustable actuator height (500–1200 mm) and sample height (300–600 mm) accommodate different chair sizes and configurations.

Q: What load ranges does it support?
Seat load: 5–300 kg; back load: 5–100 kg. The adjustable force range allows testing across light-duty to heavy-duty seating products.

Q: Can I adjust the test speed and cycle count?
Yes. Test speed is adjustable from 1 to 30 cycles per minute, and cycle count can be set from 1 to 999,999, providing full flexibility to match specific standard requirements or custom test protocols.
