– A new currency note has a very low COBB Value.  i.e. Even if you dip it in water, it will absorb very less water.
– A newsprint paper on the other hand has a very high COBB Value.   i.e. it will absorb water very quickly.

Types of Test :
– Cobb Index : ( 60 / 120 Second Test )
– Cobb Index : ( 30 Minute Test )

Confirms to : TAPPI T441 / ASTM D 3285 / ISO 535
