Barcol Hardness ASTM D
The Barcol hardness test characterizes the indentation hardness of materials through the depth of penetration of an indentor, loaded on a material harrness and compared to the penetration in a reference material. The Barcol hardness test is generally used on soft materials such as rigid plastics. It measures hardness based on indentation of a sharp point with a flat tip. Need help or have a question?
