Look at the Table of Paperboard Test Data in file PPR.BSE. To specify a material, data are required in columns 1 and 2. Any combination of additional known data are next entered in columns 3-11. Materials High, Arch, Arch90, and 90% represent a case where instrumentation are available to test paper for caliper and edgewise
used with all materials specified according to a fixed choice of test methods. Nevertheless, this example shows what results when the missing data correlation constants are invoked. Four selections of input from 28 = 256 possible combinations are shown for material Paper1. Execute PPR. Input that yield equal output where chosen with prior knowledge of the results.
