TISSUE – TENSILE STRENGTH after immersion in water
Purpose of the test
This test is performed to determine the tensile strength of wet tissue.
Procedure
Operate the instrument in accordance with ISO 12625-5 and the manufacturer’s instructions at a test speed of 50 mm/min.
The soak time for the sample is 15 s with the soaking apparatus left in place during the test.
From each test piece cut one test strip 50,0±0,5 mm in width.
The test span must be 43,5±1,0 mm (measured from top of the bar to the bottom of the top clamp, see EN 12625-5 for details).
Report 10 measures in N/m, their mean and standard deviation, calculated to 3 significant figures.
