End-loading Procedure

This procedure is based on ASTM D 695 and has been further developed in various standards. It involves loading the specimen longitudinally between two pressure plates. A buckling support prevents premature failure of the material through bending. 

The test consists of two parts: 

• To measure the compressive modulus, a specimen without cap strips is used. The strain is determined using a strain gage. 

• To measure the compressive strength, the specimen is reinforced with cap strips to avoid premature failure at the force transmission points.
