offline
This method, applicable to uncoated and coated papers, is designed to measure the surface strength of paper or
its resistance to picking. It is not applicable to loosely felted papers such as blotters or roofing felts, nor to papers
containing materials that soften with heat such as waxes or latex type additives. Light weight papers that lack stiffness
may slip under the block during the wax removal step are not suitable for testing by this procedure.
