Scope

This part of GB/T39693 specifies the method for measuring the apparent hardness of rubber rollers (expressed in international rubber hardness). This method is similar in principle to the method for measuring rubber hardness in ISO48 2, and it is essentially determined by measuring the spherical indenter under a specified force
