Frequently Asked Questions
Q1:What is this equipment used for?
It evaluates how well a chair backrest withstands the repeated rearward force from users leaning back—essential for validating durability and meeting BIFMA certification requirements.
Q2:How does it work?
The machine uses a pneumatic cylinder to apply a controlled cyclic load to the chair backrest at a specific angle and position while the seat is weighted. PLC controls manage the test cycle precisely.
Q3:What standards does it comply with?
ANSI/BIFMA X5.1 sections 10, 15, 16, and 18—the primary North American standard for office chair testing.
Q4:What types of chairs can be tested?
Office chairs, conference chairs, task seating, and residential chairs with backrests. The adjustable loading position accommodates various backrest heights.
Q5:What force levels can it apply?
Two preset levels: 334 N (75 lb) and 445 N (100 lb), selectable based on the chair type and test requirement.
Q6:How long does a typical test take?
At 10–30 cycles per minute, an 80,000-cycle test runs approximately 44–133 hours; 120,000 cycles runs 67–200 hours, depending on the selected speed.
Q7:What air supply is required?
A stable 6 kgf/cm² or higher air source. The pneumatic system requires consistent pressure for accurate force application.
Q8:What industries use this equipment?
Furniture manufacturers, testing laboratories, certification bodies, procurement QA teams, and institutional buyers specifying furniture durability.
