Compression set fixtures CS 3000 for constant deflection testing according to ISO 815, DIN 53517, ASTM D 395 and other International Standards.
Compression set testing measures the ability of rubber to return to its original thickness after prolonged compressive stresses. As a rubber sample is compressed over time between two flat parallel plates with a predefined percentage and kept for a specific time at a certain temperature, it loses its ability to return to its original thickness. This loss of resiliency, also called memory or permanent set, characterizes the capability of an elastomeric product to perform over a long period of time. MonTech Compression set fixtures are entirely made of precision ground stainless steel and feature stiff compression plates as well as sets of spacers according to customer choice. Two standard dimensions of compression set test fixtures are readily available from stock – each size is available in a single and double layer configuration. Optionally suitable tempering ovens, height gages and curing moulds in accordance with standards are available.
