Catalog excerpts

The compression platens are used to perform compression tests on a wide range of materials and components. This allows a variety of tests to be performed for determination of compression modulus, compression strength, and compression yield strength. Easy to install, these compression platens are precisely machined fixtures that are designed for even distribution of compression loads during a test. Spherical seating is available for applications that require self-alignment of the compression platens. To aid the operator on larger diameter anvils, laser etched circles on the platen surface allows for easier centering of the specimen body. On the edge of the platen is a provision for the attachment of optional displacement transducers, allowing you to measure the direct displacement between two equal sized platens during a compression test. PRINCIPLE OF OPERATION The compression fixture has been designed to easily provide the capability of compression. Platens are rigidly fixed and are non self-aligning. They have a high stiffness that resists off center loads, which retains the parallelism during specimen failure. Universal spherical seating is designed for use with compression anvils to ensure that loading is concentrically and evenly applied to specimens that do not stand perpendicular to the platen surface. APPLICATION RANGE • Type of loading: Static compression, compression-compression cyclic tests • Specimen material: Foam, plastic, metals, alloys, packaging, wood, composites, ceramics and other materials • Specimen shapes: Square, cylindrical cubes, components FEATURES AND BENEFITS • A range of different diameter sizes and load rated capacities are available • Conforms to ISO, ASTM, DIN and many other standards • 150mm to 300mm (5.9 in to 11.8 in) diameter platens are laser etched with concentric rings for accurate specimen placement • Optional spherical seating for concentric and evenly applied load • Provision for attachment of optional displacement transducers • Rugged design for minimum maintenence • Temperature range: -150 °C to 300 °C (-238 °F to 572 °F)
