icon youtube
These automatic COMPACT-Line compression testers fulfil all the strict requirements of ASTM Standards (ASTM C39, C140, AASHTO T22) in terms of load measurement accuracy, load rate application, compression platens hardness and flatness. They feature two types of spherical seats designed to strictly match the geometrical dimensions specified by ASTM Standards for testing, respectively, cylinders and blocks to ensure uniform load distribution all over the specimen and consequently accurate test results.
