Platens Surface Hardness Certificate
The standards prescribe a minimum surface hardness depending on the type of test to be performed.
The standards prescribe a minimum surface hardness depending on the type of test to be performed. When required, the hardness verification is performed with certified instruments. This option is identified by the Certificate code shown on the following table.
