This standard specifies the requirements and testing methods for prelaminated cement bonded particle boards. It covers aspects like materials, dimensions, physical and mechanical properties, surface quality, and workmanship. The boards are intended for interior use in applications like partitions, wall panelling, false ceilings, and furniture.

Practical Notes
Ensure the core board conforms to IS 14862, as the final product's quality is highly dependent on it.
These boards are heavy (density > 1000 kg/m³), so ensure the supporting framework for partitions or false ceilings is designed to handle the weight.
For areas with potential moisture exposure, proper edge sealing is crucial to prevent water ingress, despite the material's good inherent resistance.
