IS 2361:1967 is the Indian Standard (BIS) for 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.

|---|---|---|---|
| Modulus of Rupture (MOR) - Interior Grade | ≥ 10.8 N/mm² (for normal density) | ≥ 13 N/mm² (for 13-20mm thickness) | EN 312:2010 (Type P2) |
| Internal Bond (Tensile Strength Perpendicular) | ≥ 0.29 N/mm² (for normal density, interior grade) | ≥ 0.35 N/mm² (for 13-20mm thickness) | EN 312:2010 (Type P2) |
| Thickness Swelling (24h Water Immersion) | ≤ 15% (for interior grade) | ≤ 12% (for 13-18mm thickness) | EN 312:2010 (Type P2) |
| Formaldehyde Emission (Chamber Method) | Not specified | ≤ 0.1 ppm (E1 Class) | EN 312, referencing EN 717-1 |
| Thickness Tolerance | ± 10% | ± 0.3 mm | EN 312:2010 |
| Density Classification | Primary classification: Normal (400-900 kg/m³) & Low (<400 kg/m³) | Not a primary classification; density is a resulting property, typically 600-750 kg/m³. | EN 312:2010 |
