(Terminology)Standard Terminology Relating to Wood-Base Fiber and Particle Panel Materials
Standard Terminology Relating to Wood-Base Fiber and Particle Panel Materials
SCOPE
1.1 This terminology standard covers a repository of terms and classifications essential for the business of Subcommittee D07.03.
1.2 Terms and classifications for inclusion in this terminology standard when needed for general use in the conduct of the standards over which Subcommittee D07.03 has jurisdiction.
1.3 The terms in this standard pertain to cellulosic boards or panel products 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.
1.4 This international standard was developed in accordance with internationally recognized principles on standardization established in the Decision on Principles for the Development of International Standards, Guides and Recommendations issued by the World Trade Organization Technical Barriers to Trade (TBT) Committee.

Standard Terminology Relating to
Wood-Base Fiber and Particle Panel Materials
This standard is issued under the fixed designation D1554; 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 (´) indicates an editorial change since the last revision or reapproval.
INTRODUCTION
The terms included in this terminology standard 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.
