2、ase of revision, the year of last revision. A number in parentheses indicates the year of lastreapproval. A superscript epsilon (e) indicates an editorial change since the last revision or reapproval.This standard has been approved for use by agencies of the Department of Defense.1. Scope1.1 This sp
3、ecification covers fiberboard primarily used forthe fabrication of boxes and interior details such as pads,sleeves, liners, partitions, die-cut sheets, etc.1.2 The performance of fiberboard boxes is largely depen-dent on the paper components from which they are fabricatedand, in the case of corrugat
4、ed boxes, on the flute structure aswell. Therefore, a variety of grades reflecting varied perfor-mance levels are specified.1.3 The values stated in either inch-pound units or SI unitsare to be regarded separately as standard. Within the text, theSI units are shown in brackets. The values stated in
5、eachsystem are not exact equivalents; therefore, each system mustbe used independently of the other. Combining values from thetwo systems may result in non-conformance with the standard.See IEEE/ASTM-SI-10 for conversion of units.1.4 The following safety hazards caveat pertains only to thetest porti
