*1 Test Method: SEMI 67-0996
- Crumpling: Test-piece of size A5 is manually rubbed once every 15 second for 200 seconds.
- Rubbing : Two test-piece of size A5 are prepared and put together, front and back, and manually rubbed three times every 10 seconds for 200 seconds.
- Tearing/Crumpling: Test-piece of size A5 is torn at four places (4cm interval) once every five seconds and then crumpled for 180 seconds in the same was as for the rubbing test.
*2 Test Method: TAPPI (Technology of US Pulp & Paper industry)
Paper 40g cut into about 2cm square is put in water of 2 liters at ordinary temperature and time to complete dissolving is measured using TAPPI standard pulp.
