Project Page 5 Report Thirty NTRODUCTON The continuous base-line study (modified) is a compilation of monthly averages of mill test data obtained routinely on six major grade weights of linerboard manufactured in the member mills of F.K.B.., nc. Mill data are included for moisture content, basis weight, caliper, and bursting strength tests made on the production of individual machines which produced at least 5 tons of one or more of the following six major grade weights during a given month: 26, 33, 38, 42, 69, and 9 lb. At the nstitute, the as-reported basis weight, corresponding to the as-reported moisture content, is adjusted to a moisture content of 7.8%. Both the as-reported and the adjusted basis weight averages are included in the report. PRESENTATON OF DATA For the six major grade weights of linerboard referred to earlier, mill test averages for moisture content, basis weight (reported and adjusted), caliper, and bursting strength are compiled in the following tables. Table Number Description - Mill Test Averages on 26-lb. Linerboard - V Mill Test Averages on 33-lb. Linerboard V - V Mill Test Averages on 38-lb. Linerboard V - V Mill Test Averages on 42-lb.

The procedures used in calculating adjusted basis weight, cumulative machine averages, machine factors, machine indexes, and FK indexes are described in the Appendix. t should be explained that the number of machines for which data are compiled in each table for a specified month varies for these reasons: a machine must have (a) produced at least 5 tons of the pertinent grade weight during the specified month, or (b) produced 5 tons of the pertinent grade weight during any one or more of the 12 months prior to the specified month (so that a cumulative average is available), to be included in a given table.
