7 Fourdrinier Kraft Board Group Page 2 of The American Paper Institute Report Forty-Eight Project ITRODUCTIO The continuous base-line study (modified) is a compilation of monthly averages of mill test data obtained routinely on 26-lb corrugating medium manufactured in the member mills of F.K.B.G. Mill data are included for moisture content, basis weight, caliper, and Concora made on the production of individual machines which produced at least 5 tons of this grade weight during a given month. PRESETATIO OF DATA For the 26-lb grade weight of corrugating medium referred to earlier, data on conditioning and testing environments, mill test averages for moisture content, adjusted basis weight, caliper, and Concora results are compiled in the following tables. Table umber I-II-III IV Description Mill Test Averages on 26-Lb Corrugating Medium Data on Conditioning and Testing Environments The procedure used in calculating cumulative machine averages, machine factors, machine indexes, and F.KoB.G. indexes are described in the Appendix. It 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 26-lb corrugating medium during the specified month, or (b) produced 5 tons of 26-lb corrugating medium 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.
