1、Designation: D4727/D4727M 17Standard Specification forCorrugated and Solid Fiberboard Sheet Stock (ContainerGrade) and Cut Shapes1This standard is issued under the fixed designation D4727/D4727M; the number immediately following the designation indicates theyear of original adoption or, in the case
2、of revision, the year of last revision. A number in parentheses indicates the year of lastreapproval. A superscript epsilon () indicates an editorial change since the last revision or reapproval.This standard has been approved for use by agencies of the U.S. Department of Defense.1. Scope*1.1 This s
3、pecification 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 corruga
4、ted 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 port
