The standard specimens are used to determine the deformation behaviour of foam mouldings and foam standard specimens.
The specimen lies on a perforated plate or, when testing moulded parts according to DIN 53579-1, in specially standardised matrices.
The specimen penetrates the foam at a constant speed to determine a force-displacement diagram.
The shape (round or square) and the area of the specimen are specified in the basic standards ISO 2439, ISO 3386 and ASTM 3574.
The factory standards of different car manufacturers are based on these standards, but sometimes evaluate the results differently.
The test specimens are equipped with a standard D16 receptacle with cross hole for D8 pins and are connected to the load cell.
