EUROLAB, with its state-of-the-art accredited laboratories and expert team, provides precise and fast testing services within the scope of ISO 2039-1 testing. This part of ISO 2039 specifies a method for determining the hardness of plastics and ebonite by means of a loaded ball recess tip.
The ball indentation hardness determined by this method can provide data for acceptance or rejection under research and development, quality control, and specifications.
The method consists of forcing a ball to the surface of the test sample under a certain load. Print depth is measured under load. The surface area of the dimension is calculated from its depth. The ball indentation hardness is then calculated from the following relationship:
Ball indentation hardness = applied load/impression surface area
The hardness tester mainly consists of a frame with an adjustable platform equipped with a plate to support the test specimen, a recess with the associated fittings, and a device for applying the load without impact.
Unless otherwise specified, perform the tests in the same atmosphere used for conditioning. Place the test specimen on the support plate with the test specimen fully supported and its surfaces perpendicular to the direction of the applied load.
Perform the test in such a way that any bubbles or cracks in the test specimen do not affect the result. If multiple determinations are made on the same test specimen, ensure that the indentation points are at least 10 mm apart from each other and from the edge of the test specimen.
