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 recognized 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 recognized 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 DLG Approved Test“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, were measured and a permanent tread load was applied. The test was based on the DLG Testing Framework for elastic stable flooring, as at April 2010. Other criteria were not investigated.
The cover mat for lyingbox mattresses Family Code: 1316 tested here was investigated with regard to durability properties on test stands in the DLG-APPROVED test for single value-determining criteria. The abrasion resistance, the slip resistance, the acid resistance and the cleaning distance were measured.

Description and specifications
The Animat Animattress 1-40 tested here, an elastic floor for cubicles in cubicle houses
- thickness approx. 43.0 mm
- Surface: black
- Undersite: coppery colour
- Thickness: ca. 3 mm
- Shore A hardness: approx. 75
- Mattress underlay made of approx. 40 mm thick PU foam sheet
- seamless installation.
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 (= 8.13 N/cm² surface pressure). The friction element was cooled continuously with water to prevent an influence of the generated heat during the abrasion test. The size of the grinded area was 61.5 cm².
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.
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.
In test bench 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 abrasion depth after 10,000 cycles amounted to 0.2 mm, this corresponds to approximately 6 % of the mat thickness. From the ground surface 0.2 grams were rubbed off. The abrasion depth and the slight grit implicate a good wear resistance of the cover mat.
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 = 0.45 which speaks for a good foothold.
In test bench trials with a high pressure cleaner damage to the mat only occurred when a minimum distance of 40 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.
The cover 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 cover mat seems to be good suited for the described use.

Based on test-stand investigations, the criteria tested in this DLG-APPROVED test for single value-determining criteria evaluate the durability properties of the cover mat for lyingbox mattresses Family Code: 1316. The tested cover mat for lyingbox mattresses Family Code: 1316 met the requirements of the Testing Framework with respect to the investigated criteria.
