Test Standard: EN 1975
Applications & Test Purpose
The Mattress Durability Tester has been manufactured to determine the durability of any type of mattress and box spring unit, regardless of the materials of construction, by simulating long-term use conditions. Using a cylinder (both ends of the diameter of 250 mm, the middle part of the 300mm), rolling back and forth on the mattress, simulate human motion to assess the durability of mattress.
EN Hardness & Height Change Test
Standard Features
| Load block | Diameter 355 mm, Spherical radius of curvature 800mm, Front edge radius of curvature 20mm |
|---|---|
| Speed | 90mm/min |
| Stroke | 350mm |
| Driving method | SMC brand electric cylinder |
| Load cell | 200kg (Germany brand tecsis) |
| Load plate position adjustment | 300mm |
| Height change test | |
| Test method | High-precision servo measuring system |
Test Standard: EN 1957
Application & Test Purpose
The 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.
After simply loosening the front frame reinforcement the specimen can be inserted into a flexible test base plate. This makes the testing device very effective and space-saving.
Software allows for a flexible parameter entry, the execution of different testing procedures, a graphical representation of measured values, test evaluation, and logging. Then the pre-set number of cycles is reached, the test is ended automatically.
Edge Test
Standard Features
| Test Force | 1000N |
|---|---|
| Driving method | Air cylinder |
| Times | 5000 cycles |
| Hold time | 3S |
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
