Frequently Asked Questions

1. What is this equipment used for?
This tester evaluates chair armrests, legs, and footrests for static strength and fatigue durability. It simulates real-world loading to ensure seating products meet BIFMA X5.1 requirements before they reach the market.

2. What standards does it comply with?
It complies with ANSI/BIFMA X5.1-2011, specifically test methods 11.4 (front corner load), 18 (leg strength), 20 (footrest durability), and 21 (arm durability).

3. What types of chairs can be tested?
The machine accommodates most office and commercial seating with armrest heights from 500 to 780mm. The adjustable fixture system allows for various chair frame designs and sizes.

4. How does the force application work?
Two systems are used: a pneumatic pulley system for static strength tests (push/pull and vertical forces) and a cable/strap system for dynamic durability tests up to 50,000 cycles.

5. What safety features are included?
Emergency stop with cylinder retraction, overload sensing, mechanical damage protection, power interruption stop, and automatic shutdown upon specimen failure or cycle completion.

6. What are the power and air supply requirements?
The machine requires 1Φ, AC220V, 3A power supply and a minimum of 6 bar compressed air for the pneumatic system.
