Assessment – Brief Summary

The Shvedoff Cubicle Mat Ecopol 24 tested here, an elastic floor covering for the resting area in cubicle houses, was investigated with regard to durability and comfort properties on test stands in the DLG Focus Test. The deformability and elasticity of the cubicle mat, the abrasion resistance, the slip resistance, the acid resistance were measured and a permanent tread load was applied.

The Method

Deformability and elasticity

The deformability is measured in new condition and following permanent tread load using ball penetration tests with a calotte (r = 120 mm) and a penetration force of 2,000 N (corresponding to approx. 200 kg).

Permanent tread load

The permanent tread load is ­measured on a test stand with a round steel foot in the standard test programme with 100,000 alternating loads at 10,000 N (corresponding to approx. 1,000 kg). The steel foot is adapted to the natural conditions as an “artificial cow foot”. The foot has a diameter of 105 mm and therefore a contact area of 75 cm²; the carrying edge of the hoof is simulated by a 5 mm wide ring on the periphery of the sole that projects 1 mm above the rest of the surface.

Abrasion test

In a standardised abrasion test
with 10.000 cycles the top cover was grinded with an emery cloth (granu­lation 280) and a grinding pressure of 500 N (= 8.1 N/cm² surface pressure). The friction element was cooled continuous with water to prevent an influence of the generated heat during the abrasion test. The size of the grinded area was 61,5 cm².

Slip resistance

The measurements were carried out with the ComfortControl test rig of the DLG test centre. A loaded (10 kg) round plastic foot (97 mm diameter, with a contact area of 74 cm², 3 mm wide ring at the periphery of the ground) was pulled with a velocity of 20 mm/s across the mat.

Acid resistance

A permanent dipping test in accor­dance to DIN EN ISO 175:2000 (performance of synthetic material against liquid chemicals) was carried out. Test samples (size 30 mm x 30 mm) were completely dipped into different test liquids for 24 hours and 28 days (room temperature 20° Celsius). In the 28 days test the liquids were changed weekly. After the 28 days the samples were washed with distillate water and  dried for 24 hours. Before and after the dipping the weight, the dimensions and the shore hardness (shore A) of the test samples were measured. Additional visual evaluation was done for alterations like colour changing, swelling, destruction or crystallisation. All samples were evaluated in comparison to the standard water.

Cleaning distance

In test stand trials with a high
pressure cleaner (approximately 145 bar, exposure period 1 minute with a 25° flat jet nozzle and a coarse dirt remover) the distance was measured where no damage occurs.

The Test Results in Detail

Deformability and elasticity

In the ball penetration tests in new condition with a calotte (r = 120 mm), penetration depth was 7.9 mm. The resulting calculated bearing pressure of 33.6 N/cm² indicates a satisfactory load on the carpal joints when lying down and getting up.

Elasticity was measured following a permanent tread load exerted by a steel foot (contact area: 75 cm²) with 100,000 alternating loads at 10,000 N. Following the endurance test, the penetration depth of the calotte increased from 7.9 mm to 8.0 mm. The bearing pressure decreased from 33.6 N/cm² to 33.2 N/cm² (see Fig. 3). This means that deformability and elasticity slightly decrease.
Evaluation see Table 1.

Permanent tread load

Wear on the surface of the mat was observed following exposure to permanent tread load on a test stand with 100,000 alternating loads at 10,000 N. No lasting de­formation was observed.
Evaluation see Table 1.

Abrasion test

The abrasion depth after 10,000 cycles amounted to 1.5 mm, this corresponds to approximately 6 % of the rubber thickness. Of the ground surface 2.9 grams were rubbed off. Evaluation see Table 1.

Slip Resistance

The slide pulling tests showed a good slip resistance on the dry or wet rubber mat surface in new condition. The measured friction coefficients (μ) all surpassed the minimal value of μ = 0.45 which speaks for a good foothold. Evaluation see Table 1.

Acid resistance

The rubber mat was resistant against the used test liquids. The differences in weight, thickness and Shore A hardness between the acid treated and not acid treated samples were minor and lay in the range of water as standard. Against the used liquids the rubber mat seems to be good suited for the described use.  

Cleaning distance

In test stand trials with a high pressure cleaner damage to the cover of the mattress only occurred when a minimum distance of 45 cm (with a coarse dirt remover) and 20 cm (with a flat-jet nozzle) was not kept. For cleaning and disinfection of the floor cover, only the cleaning agents permitted by the manu­facturer should be used. Evaluation see Table 1.

A quality mark “DLG-APPROVED for single value-determining criteria” is awarded to agricultural products which successfully passed a smaller-scope DLG usability test according to independent and recognized evaluation criteria. The test intends to highlight special innovations and key criteria of the test item. The test can focus on criteria from the DLG testing framework for full tests or on other individual features or qualitative criteria. The minimum requirements, the test conditions and procedures as well as the evaluation guidelines of the test results are determined in consultation with a DLG expert group. They comply with the generally recognized technology rules as well as with scientific and agricultural knowledge and requirements. The successful test concludes with the publishing of a test report and the awarding of a quality mark which is valid for five years following the award date.

The DLG Appoved Test “Deformability/Elasticity, Permanent Tread Load, Abrasion, Slip resistance, Acid resistance, Cleaning distance” includes technical measurements on test stands of the DLG Test Center. The deformability and elasticity, the abrasion resistance, the slip resistance, the acid resistance, the  cleaning distance were measured and a permanent tread load was applied. The test was based on the DLG Testing Framework for elastic stable flooring, as of April 2010.  Other criteria were not investigated.
