| Field of application |
ANSI/BIFMA X5.5-2008 8 Leg Strength Test |
| ANSI/BIFMA X5.1-2011 10 Tilt Mechanism Test - Cyclic |
| ANSI/BIFMA X5.1-2011 15 (i) Backrest Durability Test - Cyclic - Type I |
| ANSI/BIFMA X5.4-2005 21 Tilt Mechanism Test - Cyclic |
| ANSI/BIFMA X5.1-2011 16 Backrest Durability Test - Cyclic - Type II and Type III |
| Working Rationale |
1 Imitate human body sat in a chair and lean back action to test the back performance. |
| 2 Place 250lbs 16 dia sand bag in the seat,apply a force that is initially 90 degrees ± 10 degrees to the plane of the backrest. |
| 3 Repeatly out put requested force to backrest by the autocontrol. |
| 4 Record the testing cycle, evaluate the product performance. |
| Structure characteristics |
1 Multi-function testing equipment，out-force and traveling for selection. |
| 2 Air Cylinder can be moved up -down, right-left and aslo be rotated freely. |
| 3 Out-force and travel-distance of air cylinder for selection |
| 4 When the form-device left the Backrest, the back will return the original state without any resistance. |
| 5 Precision manual pressure regulating valve ensure to get the stable and reliable output force and indicate from the digital display. |
| 6 RPM disply can be adjusted. |
| Parameter |
1 More than 150kg out-force. |
| 2 More than 1000mm testing platform |
| 3 600mm Air cylinder traveling |
| Hight ajustment：600-1600mm. |
| Rotation: 90 degree |
| Max Air cylinder Cyclic rate: 20 RPM; |
| Test objects |
Tilt Mechanism test-Cyclic and Back Durability test |
| Control System |
Multi-function for adjustable Hight,our-force degree and rotation. |
| Out-force and travel distance for control |
| Touch Screen+PLC,Power off memory and breakpoint stop function. |
