Mechanical testing equipment for the determination of elasticity, adhesion and elongation of paint on sheet metal. The frame has a bending lever with a roller which pivots on a steel conical mandrel with a diameter from 3.2 to 38.1mm (0.12 to 1.5"). A graduation indicates the mandrel diameter in mm and inches.
This particularly robust and rigid construction provides excellent resistance to deformation and long service life. The specimen can be bent on part of or along the entire length of the mandrel, and the results (cracks) corresponding to different test diameters can be observed in a single operation.
|Elasticity & Resistance Deformation|
|Elasticity and resistance to deformation are part of the key physical properties required in the coatings industry today. Essentially there are three different test methods which are used to determine a coating’s performance under different deformation conditions.|
|Bend Test : A coated metal sheet is bent over a cylindrical or conical mandrel and the coating observed for cracks and discolouration.
Impact Test : A coated metal sheet is placed beneath a falling weight and the resultant damage caused by the deformation is observed. The impact test method is used to identify how the coating performs under a rapid deformation process.
Cupping Test : A coated sheet metal is subjected to a gradual deformation by a polished die. This deformation is caused by the die being pushed from beneath the coating – i.e. from the reverse side of the sheet metal. The end-point is when the coating begins to crack.
