Standard Terminology Relating to

Wood-Base Fiber and Particle Panel Materials
This standard is issued under the fixed designation D 1554; the number immediately following the designation indicates the year of
original adoption or, in the case of revision, the year of last revision. A number in parentheses indicates the year of last reapproval. A
superscript epsilon (e) indicates an editorial change since the last revision or reapproval.
INTRODUCTION
The terms included in this terminology are intended to apply to a family of lignocellulosic panel
materials specially manufactured for use industrially as components (core, facing, or panels) of
furniture, cabinets, and the like, and in building construction as siding, sheathing, partitions, door
cores and paneling, acoustical treatments, and as structural components there and elsewhere where the
combination of thickness, panel size, and properties satisfy a particular need. The usual alternative
materials to these wood-base panel materials are wood in the form of lumber and plywood, plastics,
inorganic fiber cement boards, and gypsum board.
The terms used and defined herein differ slightly from some practice. Modifications appeared to be
desirable to clarify the nomenclature since confusion exists because of the similarity of some existing
terms with those for other materials.The use of the terms herein will do much to standardize the terms
pertaining to cellulosic fiberboard, hardboard, and particleboard, the principal materials included. The
board or panel materials included are those derived from wood and the woody tissue of such plants
as bagasse, flax, and straw. They fall into two general groups: (1) those manufactured from
lignocellulosic fibers and fiber bundles where in manufacture the interfelting of the fibers and a natural
bond are characteristics, and (2) those boards manufactured from a wide range in size and shape of
particles ranging from fine elements approaching fibers in size to large flakes which are blended with
synthetic resin adhesive and consolidated into boards characterized by the resin bond and usually
known as resin-bonded particleboards or more commonly as particleboards.
