Describes a method for determining the apparent hardness of vulcanized rubber roller covers. The method is similar to those used for determining of the hardness of rubber vulcanizates. It consists essentially of measuring the depth of penetration of a spherical indentor operating under a specified force. Covers time-interval between vulcanization and finished grinding, and testing and conditioning and temperature of test.
