Are general purpose particle boards suitable for exterior environments?

No, they lack the required moisture and weather resistance and should be restricted to interior applications.

What is the acceptable moisture content at the time of delivery?

The moisture content should generally be maintained between 5 and 15 percent.

Which code dictates the testing methodology for these boards?

IS 2380 provides the detailed methods of test for wood particle boards and other lignocellulosic materials.

IS 2361

: 1967

Particle Boards of Wood and Other Lignocellulosic Materials (for General Purposes) - Specification

This standard prescribes the requirements for the manufacture, dimensions, tolerances, and physical and mechanical properties of general-purpose particle boards made from wood and other lignocellulosic materials. It serves as a benchmark for ensuring adequate strength, density, and moisture resistance for interior applications.

Specifies the requirements for particle boards manufactured from wood and other lignocellulosic materials for general use.

Quick Reference Values

moisture content limit5% to 15%

thickness tolerance± 5%

length and width tolerance± 3 mm

water absorption 24h maxTypically 15% to 20% depending on grade

Practical Notes

General-purpose particle boards are strictly intended for interior use and must be protected from direct moisture and humid environments.

Edges of the particle board must be properly sealed or edge-banded to prevent rapid moisture absorption and subsequent swelling.

Always reference IS 2380 for the specific testing procedures used to validate the physical properties of these boards.
