Standard Specification for Corrugated and Solid Fiberboard Sheet Stock (Container Grade) and Cut Shapes

ABSTRACT
This specification covers corrugated and solid fiberboard sheet stock (container grade) and cut shapes intended for use mainly in the fabrication of boxes and interior details (for example, pads, sleeves, liners, partitions, and die-cut sheets). Covered in this specification are three classes (domestic and domestic/fire retardant, weather resistant and weather resistant/fire retardant, and water and water-vapor resistant and water and water-vapor resistant/fire retardant) of corrugated fiberboard and two classes (domestic and domestic/fire retardant, and weather resistant and weather resistant/fire retardant) of solid fiberboard, with a variety of grades reflecting the varied performance levels of the fiberboards. Corrugated fiberboards shall be manufactured with two, three, or four facings for single-, double-, or triple-wall varieties, respectively, with each facing separated by and securely adhered to the corrugating medium of any suitable fiber. Solid fiberboards, on the other hand, shall be manufactured from plies securely and continuously laminated together. The facings of corrugated fiberboards and plies of solid fiberboards shall conform to the requirements specified. Tests for thickness, basis weight, puncture resistance, ply separation, bursting strength, flame spread, specific optical density, and edge crush shall be performed and shall conform to the requirements specified.
SCOPE
1.1 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, in the case of corrugated boxes, on the flute structure as well. Therefore, a variety of grades reflecting varied performance levels are specified.
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 units are shown in brackets. The values stated in each system are not exact equivalents; therefore, each system must be used independently of the other. Combining values from the two 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 the test portion, Sections 8 and 9, of this specification: This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use.
