|---|---|---|
pH | 7.5-10.0 | All layers of the paper must meet this requirement. |
Alkaline reserve(calcium carbonate equivalent) | 2% |
|
Tear resistance | 350 mN (CD & MD) for all papers over 70 g/m2 | A formula is provided for finding tear resistance value for lighter weight papers. |
Resistance to oxidation | Kappa number under 5.0 | This requirement limits lignin and other material that may oxidize. It takes the place of "Fiber quality" or "No groundwood or unbleached fibers" in other standards. |
