BS 5669-4:1989 — Particleboard — Specification for cement bonded particleboard
This part of BS 5669 specifies the requirements for cement bonded particleboards, which are flat boards manufactured from wood particles and a hydraulic cement binder. It covers:
Types and classification of cement bonded particleboards according to their properties and intended use.
Physical and mechanical requirements, including density, moisture content, bending strength, modulus of elasticity, internal bond, surface soundness, and resistance to impact.
Dimensional characteristics, such as tolerances on length, width, thickness, edge straightness, and squareness.
Durability and performance requirements, including resistance to moisture, fire, biological attack, and frost.
Sampling, inspection and testing procedures to determine compliance.
Marking requirements for identification of boards meeting the standard.
