Ring Stiffness Testing Machine

The ring stiffness of pipes is one of the significant indicators for the assessment of pipe stability. This test allows to determine the resistance of the external load of plastic pipe.

AL-UN H machine conforms to ISO 527, ISO 6259, ASTM D 638, ASTM D 624, ASTM D 412 standards and is equipped to perform dynamic and static tests with a certain frequency cycle.
