Test report 7497
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” includes technical measurements on test stands of the DLG Test Center. The deformability and elasticity 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 Aquastar Waterbed 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 APPROVED Test for single-value-determining-criteria. The deformability and elasticity of the waterbed were measured and a permanent tread load was applied. Requirements of DIN 3763 fulfilled in the examined criteria. Deformability and elasticity class 4 according to DIN 3763.

The product
Description and Technical Data
The Aquastar Waaterbed tested here is an elastic floor covering for use in the resting area of high cubicles in cubicle houses;
it contents waterbed with a latexfoam underlay.
- Surface with groove profil
- Thickness Latexfoam: approx. 30 mm
- Thickness complete: approx. 70 mm
- Shore A hardness: approx. 70
- laid as sheeting
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 rig with a round steel foot 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.
The test results in detail
Deformability and elasticity
A penetration depth of 29.6 mm was determined in ball-indentation tests in new condition with a calotte (r = 120 mm) and a penetration force of 2,000 N (corresponding to approx. 200 kg). A bearing pressure of 9.0 N/cm² was calculated from this, indicating a relatively small load on the carpal joints when lying down and standing up.
The elasticity was measured following a permanent loading test with 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 decreased from 29.6 mm to 25.6 mm. The bearing pressure increased from 9.0 N/cm² to 10.4 N/cm² (see Figure 2). This corresponds to a decrease in deformability and elasticity.
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 Aquastar Waterbed for use in the resting area of high cubicles in cubicle houses. The tested Bioret Aquastar Waterbed met the requirements of the Testing Framework and DIN 3763 with respect to the investigated criteria.
