The ‘set’ is the residual strain in a rubber test piece after it has been subjected to stress for a given time and then allowed to recover for a given time, the temperature being substantially constant during the test. 'Compression Set' is the residual compression strain after compression, (a) to a given compression strain, or (b) a given compression stress.

Two or more circular steel plates, 12.5mm thick and 126mm diameter, are clamped together with three bolts. Spacers of the appropriate thickness in the form of rings around each bolt are placed between the plates to control the thickness of the test pieces whilst compressed. Loose stainless steel discs are interleaved between the main plates to provide a highly polished surface in contact with the test pieces. These discs may easily be replaced should they become scratched, pitted or damaged.
The apparatus is available with single daylight (2 plates), double (3 plates) and triple daylight (4 plates). It can also be supplied with spacers of the required thickness to meet the ISO (Model C3) or the ASTM (Model C4) specifications. When ordering please state whether ISO or ASTM model is required, and also the number of daylights (or the number of plates).
