Technical parameters of Bifma X5.1 Chair backrest Tilt Mechanism Test Machine:

Technical parameters:

Standards:
ANSI/BIFMA X5.1-2012 ,EN 1335: 2000

5. Adjust the cycling device to move the mechanism between the front and back stops, without overriding or impacting either stop

Reference test method
Standards: BIFMA X5.1-2011-13 Arm Strength Test - Vertical - Static :
13.1 Applicability: This test applies to all chairs with arms.
13.2 Purpose of Test: The purpose of the test is to evaluate the ability of a chair and arm to withstand stresses caused by applying vertical forces on the arm(s).

a) A force of 750 N (169 lbf.) shall be applied for one (1) minute.
b) Remove the force.

13.4.2 Proof Load
a) A force of 1125 N (253 lbf.) shall be applied for one (1) minute.
b) Remove the force.
