Pick Resistance
Purpose of the test
This test is performed to determine the pick resistance of paper, solid board or folding board.
Procedure
Operate the instrument in accordance with ISO 3783 and the manufacturer’s instructions.
Leave the samples exposed for 24 h to 23°C and 50% R.H., according to ISO 187.
Set the printing speed (accelerated) to 1,0 m/s for Level 1 and 3,0 m/s or 4,0 m/s for Level 2.
Set the printing pressure to 350 N.
Measure the pick resistance on the marked side of 10 test pieces with the marking in the clamp.
Use IGT medium viscosity pick test oil for both Level 1 and Level 2.
Report 10 measures in m/s, their mean and standard deviation calculated to 3 significant figures.
