ZwickRoell has designed a load frame for larger molded foam pieces. Build in the shape of a C, it facilitates excellent access on three sides. A feed table is available for mattresses, which is used to easily push them into the required testing position. The lateral contact plate can be folded down on this machine type to test smaller moldings or to perform tensile tests.

The modern measurement and control electronics enables adaptive travel and force control functions. This is particularly advantageous for hysteresis tests and when determining the comfort class to Volkswagen PV 3410 in order to approach the end positions of the cycles with precision and at a constant speed.

ZwickRoell standard machines can be used to test slab foam with dimensions of 380 x 380 mm to ISO 2439 and ASTM D3574. These machines are equipped with a function for compensating for the stiffness of the load frame, which enables precise measurement of the indention depth.

testXpert II has an entire library of programs that cover all of the relevant DIN, ISO and ASTM standards. Furthermore, ZwickRoell offers many standard testing machines that comply with the factory standards of automobile manufacturers such as Volkswagen Group, DaimlerChrysler, BMW, GM, PSA Group, Ford, and other renowned companies.
