Hardness is measured in three places; approximately 50 mm (2 in) from both ends and the middle of the roll face. Four to five measurements are taken at each place and an average reading is recorded. 68 to 70 Shore C is usually minimum hardness allowed and the readings should be within one unit. 72 – 74 or 76 – 78
