The stress is applied at a constant force on a specimen with a Ø of 29.0 mm ± 0.5 mm
Compression set is equipped with a spring, accurately calibrated in order to feature an elastic constant of 70 kN/m (±3.5 kN/m) at a force of 1.8 kN
The plotting of spring deformation is originated by a Vernier scale, at a 1/20 mm accuracy, directly applied onto movable platen in the middle
Compression set can be oven or cryostat tested at 70°C / -30°C, basing on ASTM Standards
Accurate execution of mechanical parts made of galvanised steel, painted with epoxy resins
Compression spring made of music wire, treated and stabilized at 70°C for 170 hours
The spring is accurately worked to achieve the elastic constant, as required by the standards
Supplied with a calibration diagram
Plotting system for the deformation is based on a Vernier scale fitted onto the movable platen in the middle
System sliding on a graduated scale with zero set facility, features an accuracy of 1/20 mm, that corresponds to a load of 357 g
Tightening knob operates the upper movable platen by means of a thrust ball bearing, for insuring an accurate application of load on the specimen
Overall dimensions mm 150 x 150 x 400 h
Weight approx. 13 Kg
Reference standards
ASTM D 395
