Compressive Modulus

Test ID  

A universal testing machine (UTM) is used to determine and report compressive modulus. Test specimens are right cylinders or prisms, 50 mm in length. For ASTM testing, 12.7 mm width x 12.7 mm thickness or 12.7 mm diameter specimens are preferred; for ISO testing, preferred specimens have 10 mm width x 4 mm thickness. Specimen is placed on lower platen; the cross head is lowered brought in contact. Test is initiated with cross head compressing at a constant speed. Compressive strain is measured using a compressometer. Five replicates are performed.    
A long compression specimen can be used upon request in conjunction with an antibuckling fixture.

Compression tests provide a standard method of obtaining data for research and development, quality control, acceptance or rejection under specifications, and special purposes.
