Barcol Hardness is a measure of the resistance of a material to penetration by a sharp steel point. Testing is performed with a Barcol Impressor. Barcol Hardness values range from 0 to 100, with 100 being the hardest. Each Barcol Hardness division represents a penetration of 0.0076 mm. Barcol hardness is often used to judge the degree of cure of thermosetting materials.
