EUROLAB, with its state-of-the-art accredited laboratories and expert team, provides precise and fast testing services within the scope of DIN 53863-2 testing. Circular abrasion test, e.g. It can also be claimed for friction. The results of circular wear tests cannot be directly compared with results obtained using any other wear test method.
The principle of operation of the circular rubbing device according to this standard is that a friction body equipped with additional weights comes in constant contact with the specimen clamped on a wide-angle rotating cone along the generatrix of the cone, resulting in a eroding effect in the tangential region.
The method is not suitable for testing such flat textile structures (especially very flexible woven and crocheted fabrics), whose structure can be highly deformed under the influence of small forces.
The general guidelines in DIN 53803 Part 1 and Part 2 should be followed when sampling. For the circular wear test, at least 100 circular samples with an area of 5 cm², distributed as evenly as possible on the test piece, should be cut using a punch or scissors and a template or a template. sample cutter Only loosely attached marginal threads to the edge of the sample are expediently removed, they are lost in further processing, which means that the determination of the weight loss is incorrect.
In knitted and crocheted fabrics, cardboard rings with an outer diameter of 113 mm and an inner diameter of 100 mm are glued to the sample rod before cutting and the samples are cut into the outer circle of the cardboard rings. In special cases, eg. B. When testing knitted and crocheted fabrics, the sample area can be kept smaller if the tester is equipped with an additional clamping device for small test areas.
