Compressive properties/compressive stress value/stress-strain characteristics in compression to ISO 3386
The compression stress value is the pressure resistance that a defined specimen under specified environmental conditions applies to a defined whole-surface compression.

Applicable standards for this test
The standard specimens have a quadratic cross-section with a lateral edge length of 5 or 100 mm. ASTM D3574 specifies an additional specimen with a round cross-section and a diameter of 57 mm.

Compression stress value
In this scenario, the deformation behavior of the specimen is relatively complex. Lateral movement of the cell structure with corresponding shearing occurs near the side cut surface, while the pure compression deformation is predominate in the center. For this reason it is not possible to effectively compare measured values that are determined from specimens of various dimensions using this test method.
The methods used by Renault and PSA are exceptions. The test consists of a total of five test cycles, of which the first and the last are evaluated. To increase the accuracy of the travel measurement, this standard specifies the correction for machine deformation. These correction options are available with all ZwickRoell testing machines as a standard function.
The density measurement process can be integrated in the test sequence. Density is measured using a scale that is connected to the PC.
