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 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 valuedetermining 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 for single value-determining criteria “Acid resistance” includes technical measurements in the lab of the DLG Test Center. The acid resistance was measured. The test was based on the DLG Testing Framework for stall facilities for cattle, as of September 2001. Other criteria were not investigated.

Assessment – Brief Summary

The DeLaval cubicle frame for deep bedding cubicles, was investigated with regard to durability properties in the DLG-APPROVED test for single value-determining criteria. The acid resistance was measured.

The Product

Description and Technical Data

The DeLaval cubicle frame is for deep bedding cubicles and supposed to be the boundary for the rear and front part of the cubicle. DeLaval recommends to use the cubicle frame in combination with the DeLaval flexible cubicle divider, FCD only. The profiles are made of recycled plastic.

Fixation

Rear: All elements have groove and tongue and are installed with 4pcs of anchor bolts onto the concrete floor. The elements have a length of 262 cm, which is equivalent to the dimension between center of two cubicles. Front: The front elements are being placed into the post brackets for cubicle frame between the cubicle dividers.

The Method

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.
