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.
