DLG Fokus Test Evaluation
With a cap (r= 120 mm) at a penetration force of 2000 N (corresponding to approx. 200 kg)
In new condition: penetration depth 30,7 mm.
After permanent tread load test: penetration 32,0 mm.
Elasticity was measured after exposure to a continuous tread load exerted by a steel foot (contact area: 75 cm²) in the form of 100.000 alterning loads of 10.000 N
The mattress system has been exposed to a permanent tread load exerted by a round steel foot (artificial cow’s foot) having a diameter of 105 mm (contact area 75 cm²), with a 5 mm wide ring at the periphery of the sole, which projects 1 mm over the rest of the surface ( carrying edge of the claw) withalternating loads of 10.000 N (corresponding to ca. 1000 kg)
Evaluation: no lasting deformation (++)
no appreciable wear (+)
Note: (++) is the best possible evaluation
