Deformability and elasticity
In ball penetration tests in new condition with a spherical cap (r = 120 mm) and a penetration force of 2.000 N (corresponding to ca. 200 kg), penetration depth was 26.3 mm. The calculated bearing pressure of 10.1 N/cm² indicates a relatively small load on the carpal joints during lying down and getting up.
Elasticity was measured after the cow mat had been exposed to a continuous tread load exerted by the steel foot (contact area 75 cm²) and 100.000 alternating loads of 10.000 N. After the endurance test, the penetration depth of the calotte increased from 26.3 mm to 28.0 mm. The calculated bearing pressure reduced from 10.1 N/cm² to 9.5 N/cm². This means that deformability and elasticity increas-es slightly.

cial 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 pro-jects 1 mm over the rest of the surface (carrying edge of the claw)) in test stand trials (100.000 altern-ing loads of 10.000 N (corres- ponding to ca. 1000 kg), the mattress showed no appreciable wear. Lasting deformation could not be observed.
Evaluation*
– surface no appreciable wear +– no lasting deformation ++
Abrasion test
In a standardised abrasion test dur-ing which the surface was grinded with an emery cloth (granulation 280) and a grinding pressure of 500 N (= 8.1 N/cm2 surface pres-sure), the abrasion depth after 10,000 cycles amounted to 0.8 mm, this corresponds to approximately 11 % of the rubber thickness. Of the ground surface (61.5 cm2) 0.9 grams were rubbed off.
Evaluation*The minor abrasion depth and the slight grit implicate a good wear resistance of the rubber mat +

Slip resistance Acid resistance
A permanent dipping test in accor-dance to DIN EN ISO 175:2000 (performance of synthetic material against liquid chemicals) was car-ried out. Test samples (size 30 x 30 mm) were complete dipped in different test liquids for 24 hours and 28 days (room temperature 20° Celsius).
In the 28 days test the liquids were changed weekly. Before and after the dipping the weight, the dimen-sions and the shore hardness (shore A) of the test samples was meas-ured. Additional a visual evaluation was done for alterations like colour changing, swelling or destruction.
Evaluation**
The rubber mat was resistant against the used test liquids. Because of the resistance against
the used feed- and excrement acids and the used disinfection liquid the rubber mat seems to be well suited for the described use.
** Evaluation: + = resistant; = limited resistant; – = not resistant
The measurements were carried out with the ComfortControl test rig of the DLG test centre. A loaded (10 kg) round plastic foot (105 mm diameter, with a contact area of 75 cm2, 3 mm wide ring at the periphery of the ground) was pulled with a velocity of 20 mm/s across the mat.
The slide pulling tests showed a good slip resistance on the dry or wet rubber surface in new condi-tion.
The measured friction coefficients (μ) all surpassed the minimal value of μ = 0.45 which speaks for a good foothold.

PrüfungThe DLG FokusTest included tech-nical measurements on test rigs and in the chemical lab of the DLG test station.
Deformability and elasticity were examined and a permanent tread load test was carried out. Examina-tions of abrasion resistance in an abrasion test using an emery cloth, examinations of slip resistance with the aid of slide pulling tests were carried out and the acid resistance was examined.
