Specifications:
According to test Standard: BIFMA X5.1-2002, Test No.13,14, 20
Applicability: This test applies to all chairs with armrests.
Purpose of Test: The purpose of the test is to evaluate the ability of a chair armrest to withstand
stresses caused by applying vertical forces or outward forces or repetitive loading on the armrest(s) Loading capacity:
1.Test No.13 Arm Strength Test- Vertical - Static
a) Functional Load: apply a force of 890N(2001bf) for one (1) minute.
b) Proof Load: apply a force of 1334N(3001bf) for one (1) minute. 2.Test No.14 Arm Strength Test - Horizontal - Static
a) Functional Load: apply a force of 445N(1001bf) for one (1) minute in the outward direction.
b) Proof Load: apply a force of 667N(1501bf) for one (1) minute in the outward direction. 3. Test No.20 Arm Durability Test - Cyclic
Simultaneously apply a force of 400N(901bf) to each armrest at a 10°±1°angle.
Test cycles:60,000 at a proper rate 10∽30cycles per minute. Features:
-Safety protection - Forces are measured with a precision proprotion valve via a
Peneumatic valve driver.The pneumatic input range is within 1kg/cm2∽8kg/cm2
Being able to maintain high precise constant force. A dopt high accuracy and precision peneumatic proprotion valve to ensure test stabilities and low error.
.Selectable units of system - kg N,1b
.Easy to Operate - The machine is operated via the simple and corresponding POD
(programmable operation display) system for easy setting and test.
.Test report is printed once complete test.
.Conforms to national standard - Meets national standard requirement. For more information, please contact with us.
