2)Standard :
ASTM F1566,BS EN1957, QB/T 1952.2-2011
Test items: include the following tests and measurement projects:
1.Durability test for the bed surface.( simulating the effects to the mattress after the body of people rolls on it)
2.Durability test for bed edge . ( simulate a people sits on the edge of the mattress)
3.Height measurement of the mattress.--thickness test
4.Measurement of the Hardness value.---hardness test
(also you can choice what you need : only one / 2 on 1 / 3 on1 )
Equipment characteristics:
1) Durability Test Applications& Test Purpose
Mattess Durability Tester using a horizontal hexagonal wooden drum roll or cylinder (both ends of the diameter of 250 mm, the middle part of the 300 mm, rolling back and forth on the mattress, simulate human motion to assess the durability of the mattress.
Roller for bed surface durability test:
2) EN Hardness and Height Change Test
Mattress Hardness and Height Change Test Applications & Test Purpose:
The mattress test machine combines the loading device (roll) with a hardness measuring device. Thus, firmness test can be carried out according to ASTM F 1566 or EN 1957, without the need for a rearrangement of the specimen, which would falsify the measured values. It can also display height change by servo measuring system.
3) Edge Test
Test Standard: EN1725
Applications& Test Purpose:
The machine increases mattress fatigue test function, it simulate human sitting on the edge of mattress, with 1000N force to test the fatigue of mattress for 5000 cyclic according to EN1725.
Technical parameters:
Rolling test stroke: The mattress mid-line left and right are both 500 mm.
Rolling test speed: 16±2Cycles per minute (or specified by customer)
Cylinder Roller: 1400N, The middle diameter: 300mm, Both ends diameter: 250mm, length: 1000
Hexagon style wooden roller: size as standard requirement
Counter: 0~999999can be set.
The control way of rolling: Touch screen + PLC control
Loading cushion on the edge: buttocks shape, 380mmx 495mm
Loading parts on the edge: The midpoint on the long edge of the mattress.200 mm from edge.
Loading force on the edge: 1000N
Loading time on the edge: 3S
Position of measurement: Mattress center, Left and right are both 250mm, the midpoint on the long edge
of the mattress 200 mm inward.
Loading plate of measurement: Diameter 355mm, Radius of curvature of the end R800mm
Capacity of force sensor: 2kN
Loading speed of measurement: 90±5mm/min
Stroke: 500mm
Drive motor: Servo motor
