IS 2380 specifies the testing procedures for wood particle boards and other lignocellulosic boards. It covers the methodology for evaluating key physical properties (like moisture content, density, water absorption) and mechanical properties (such as flexural strength and internal bond strength).
Methods of Test for Wood Particle Boards and Boards from Other Lignocellulosic Materials
Quick Reference Values
conditioning temperature27 ± 2 °C
conditioning relative humidity65 ± 5 %
oven drying temperature103 ± 2 °C
Key Formulas
Moisture Content (%) = [(Initial Mass - Oven Dry Mass) / Oven Dry Mass] × 100
Density (kg/m³) = Mass / (Length × Width × Thickness)
Modulus of Rupture (N/mm²) = 3PL / 2bd²
Practical Notes
Ensure specimens are properly conditioned at 27±2°C and 65±5% RH until they reach constant mass before initiating any mechanical tests.
For water absorption and swelling tests, adhere strictly to the exact immersion durations (typically measured at 2 hours and 24 hours).
When preparing samples for flexural and tensile tests, edges must be cleanly cut and free from defects to prevent premature failure or stress concentrations.
