SURFACE STRENGTH OF PAPER (WAX PICK TEST)

Paper, Static tests, Creasing, Water vapor permeability, Mass transfer.

1. This recommended practice is used for the creasing of paper and other thin sheet materials to provide reproducibly creased specimens for testing water vapor transmission . It is not applicable to paperboard.
2. The procedure described is for creasing square specimens which will yield test areas from 60 to 140 cm2 (about 10-20 in.2), although it may be adapted to other areas.
3. This procedure does not necessarily reproduce commercial creasing which is imparted kinetically , but it does provide a controlled means to assess the possible effect of creasing on the barrier properties of the material.
4. If a large number of specimens are to be prepared, a jig or template will greatly facilitate this marking.
