Elcometer 1506 Cylindrical Mandrel Bend Tester

Similar in use to the Elcometer 1510, the Elcometer 1506 is also a very robust mechanical unit for determining the elasticity, adhesion and elongation properties of cured coatings on sheet metal. The frame has a bending lever with heightadjustable rollers and a sliding vice for clamping the sample which means the test pieces are bent perfectly and regularly on decreasing mandrels until the desired effect can be observed. The instrument can be adjusted to the diameter of the mandrel used and the mandrels are easily changed. A wide range of mandrels with metric and imperial diameters is available. Mandrels are not supplied with the instrument and can be ordered as a set or individually.

Information

Elasticity & Resistance to Deformation The performance of coatings when influenced by external stresses caused by stretching, bending or impacts, determines their suitability for their designed application. A coating designed for use in the coil coating industry, for example, should have the ability to stretch as the substrate is formed into its desired shape without damage. Deformation or damage would reduce the protective quality and appearance including colour change, adhesion etc. Further, a coating designed for industrial use should be able to withstand impacts during the life of the product. In order to characterise a coating’s performance to elongation and deformation, a number of repeatable and reproducible tests have been developed. Mandrel Bend Test A coated metal sheet is bent over a conical or cylindrical mandrel and cracks, colour change, adhesion etc. of the coating are evaluated. Corresponding results, produced by decreasing mandrel sizes, indicate the degree of elasticity of the coating. A conical mandrel allows the user to undertake fewer tests to achieve a similar result to cylindrical mandrels. Cupping Test A coated metal sheet is subjected to a gradual deformation by a polished die being pushed from beneath the coating - i.e. from the reverse side of the sheet. Variable Impact Tests There are two methods: either a weight with a punch attached falls on a coated metal sheet or a weight falls on to a punch which is resting on the coated metal sheet. In either test, the damage caused is observed and evaluated. These methods are used toidentify how the coating performs under a rapid deformation process.
