Mattress Rolling Test Compression Hardness Testing Machine
Used for testing the durability of all kinds of mattresses and beds,at the same time, testing the deflection measurement of mattresses and beds,the height of cushion surface, the height of the edge, measuring the hardnessvalue of mattresses, the evaluation of the hardness grade, and automaticallyassess the soft and hard grade of mattresses.
Testobjective: a wooden hexagonal barrel or cylinder (250 mm in diameter at bothends and 300mm in the middle) that rolls horizontally is used to roll back andforth on the tested mattress, simulating human motion to evaluate thedurability of the mattress. The maximum size of the mattress is 2.2m X 2m.
QB/T1952.2-2011; GB/T26706-2011; BS EN1957-2012; GB/T26706-2011
Control and detection method: Computercontrol, automatic test results, with a key control full automation and manual testingmode. The equipment is equipped with three test methods: pavement rolldurability test, hardness test and cushion height test. All items are testedautomatically by the computer according to the standard program. After the testis completed, the system will automatically lift the roller to the initialposition.
