Test report 7603
The approval
A test mark “DLG APPROVED for individual criteria“ is awarded for agricultural products which have successfully fulfilled a scope-reduced usability testing conducted by DLG according to independent and recognised evaluation criteria. The test is intended to highlight particular innovations and key criteria of the test object. The test may contain criteria from the DLG test scope for overall tests, or focus on other value-determining characteristics and properties of the test subject. The minimum requirements, test conditions and procedures as well as the evaluation bases of the test results will be specified in consultation with an expert group of DLG. They correspond to the recognised rules of technology, as well as scientific and agricultural knowledge and requirements. The successful testing is concluded with the publication of a test report, as well as the awarding of the test mark which is valid for five years from the date of awarding.
The test was based on the DLG Testing Framework for elastic flooring for pigs, as of February 2023 and DIN 3763:2022-08 (Elastic floorings for cattle and dairy cows walking and rest surfaces – requirements and testing). Other criteria were not tested.
Assessment in brief
The PREMIUM Rubber-Topper elastic flooring is suitable for use in pig resting areas. It was tested for durability and comfort in the DLG-APPROVED for individual criteria. The requirements of the DLG testing program for elastic flooring systems for pigs (as of February 2023) were fulfiled.

The product
Description and technical data
The elastic flooring is suitable for use in pig resting areas.
- Elastic rubber surface (17 mm thick, textured with 1.3 mm-high studs and installed) for PP Copo plastic grating (rigid component, manufactured using injection molding)
- Total thickness: 64.5 mm
- Shore A: approx. 64
The method
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 250 N. 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.
Acid resistance
A permanent dipping test in accordance to DIN 7861 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.
Slip resistance
The measurements were carried out with the ComfortControl test rig of the DLG test centre. A polyamide plastic foot loaded with 10 kg, designed to simulate a pig‘s hoof (40 mm in diameter, contact area approximately 20 cm²), was dragged across the test mat at a speed of 20 mm/s.
Detailed account of the test results
Abrasion test
The abrasion depth after 10,000 cycles amounted to 1,5 mm, this corresponds to approximately 2.3 % of the rubber thickness. Of the ground surface 0.9 grams were rubbed off. The abrasion depth and the slight grit implicate a good wear resistance of the mat.
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) in this test – ranging from 0.5 to 0.7 – are significantly higher than the minimum value of μ = 0.25 (DLG test program).
Acid 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) in this test – ranging from 0.5 to 0.7 – are significantly higher than the minimum value of μ = 0.25 (DLG test program).
