Test report 7494
The approval
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 Approved Test “Deformability/Elasticity, Permanent tread load, Slip resistance” includes technical measurements on test stands of the DLG Test Center. The deformability and elasticity as well as the slip resistance were measured and a permanent tread load was applied. The test was based on the DLG Testing Framework for elastic stable flooring, as of December 2018 and DIN 3763:2022-08 (Elastic floorings for cattle and dairy cows walking and rest surfaces – Requirements and Testing). Other criteria were not investigated.
Assessment – brief summary
The Bioret alley mat Magellan tested here, an elastic floor for walking ways in cubicle houses, was investigated with regard
to durability and comfort properties on test stands in the DLG APPROVED test for single value-determining criteria. The deformability and elasticity, the slip resistance were measured and a permanent tread load was applied. Requirements of DIN 3763 fulfilled in the examined criteria.

The product
Description and Technical Data
Black profiled rubber mat with inlay at the bottom.
- thickness: approx. 30 mm
- upper side: Stepping area with V-shaped grooves (with integrated slope) and knops, grooves (width approx. 25 mm and depth approx. 19 mm) between the stepping area.
- under side: with diamond structure
- Shore A Hardness: approx. 72
- Seamless installation
The method
Deformability and elasticity
The deformability is measured in new condition and following permanent tread load with a round steel foot (diameter of 105 mm and therefore a contact area of 75 cm²) 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 250,000 alternating loads at 5,000 N (corresponding to approx. 500 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
Slip resistance
The measurements were carried out with the Comfort Control test rig of the DLG Test Center. 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 test results in detail
Deformability and elasticity
In the penetration test in new condition with 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)) and a penetration force of 2.000 N (corresponding to approx. 200 kg), penetration depth was 2.7 mm. This results in a calculated surface pressure of 26.7 N/cm².
Elasticity was measured after the Magellan Mat had been exposed to a permanent tread load exerted by the steel foot (250.000 alternating loads of 5.000 N). After the endurance test, the penetration depth increased to 3.0 mm. (see Fig. 2). Evaluation see table 1.
Permanent tread load
After the Magellan Mat had been exposed to a permanent tread load exerted with 250.000 alternating loads of 5.000 N (corresponding to approx. 500 kg), the mat showed no noticeable wear. Lasting deformation could not be observed.
Evaluation see table 1.
Slip resistance
The slide pulling tests showed a good slip resistance on the dry or wet mat surface in new condition. The measured friction coefficients (μ) all surpassed the minimal value of µ = 0.40 (DIN 3763) and μ = 0.45 (DLG test prorgram) which speaks for a good foothold. Evaluation see table 1.
Based on test-stand investigations, the criteria tested in this DLG-APPROVED test for single value-determining criteria evaluate the comfort and durability properties of the Bioret Magellan Mat for use in the walking ways in cubicle houses. The tested Bioret Magellan Mat met the requirements of the Testing Framework and DIN 3763 with respect to the investigated criteria.
