The test allows to stress the specimen under compression, through the method of constant deflection
Any specimen has a Ø of 29.0 mm ± 0.5 mm, or 130 mm Ø ± 0.2 mm
The compressed compression set is conditioned in a cell along a pre-set time at a pre-set temperature
Once cycle is completed, the specimen deflection due to constant deflection is controlled

Set of test spacers, including 6 + 6 ground bars 9.38 mm ± 0.5 mm and 4.5 mm ± 0.1 mm thick respectively (additional spacers upon request)
4 high resistance bolts, including nuts and washers
Wrench for tightening the platens
Reference standards
