3、se.1. Scope1.1 This specification covers fiberboard primarily used for the 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 dependent on the paper components from which they are fabricated and,
4、inthe case of corrugated boxes, on the flute structure as well. Therefore, a variety of grades reflecting varied performance levels arespecified.1.3 The values stated in either inch-pound units or SI units are to be regarded separately as standard. Within the text, the SI unitsare shown in brackets.
5、 The values stated in each system are not exact equivalents; therefore, each system must be usedindependently of the other. Combining values from the two systems may result in non-conformance with the standard. SeeIEEE/ASTM-SI-10 for conversion of units.1.4 The following safety hazards caveat pertai
