PUNCTURE RESISTANCE
Purpose of the test
This test is performed to determine the pucture resistance of solid board or folding board.
Procedure
Operate the instrument in accordance with ISO 3036 and the manufacturer’s instructions.
Leave the samples exposed for 24 h to 23°C and 50% R.H., according to ISO 187.
Determine the puncture resistance, two measures per test piece ensuring that side marked ‘Test this side’ is uppermost and the arrow is pointing towards the pendulum hub.
Report 10 measures in J, their mean and standard deviation calculated to 3 significant figures.
