IS 2380:2000 is the Indian Standard (BIS) for methods of test for wood particle boards and boards from other lignocellulosic materials. 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).

! 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.
Standard Test Methods for Evaluating Properties of Wood-Base Fiber and Particle Panel Materials
A comprehensive standard consolidating multiple test methods, very similar in structure and intent to IS 2380.

MediumCurrent
Wood-based panels — Sampling, cutting and inspection — Part 1: Sampling and cutting of test pieces and expression of test results
Covers sampling and test piece preparation, which is Part 1 of IS 2380; the actual test methods are in separate EN standards (e.g., EN 310, EN 317).

Wood-based panels — Determination of bending strength and modulus of elasticity
Directly equivalent to IS 2380 (Part 5) for bending tests, but IS 2380 covers many more tests in a single document.

This is a product specification but references or describes test methods that often align with those in IS 2380.
Key Differences
≠Standard conditioning temperature in IS 2380 is 27 ± 2 °C, reflecting a tropical climate, whereas European (EN) and ISO standards specify 20 ± 2 °C, reflecting a temperate climate.
≠IS 2380 is a single comprehensive document containing over 20 different test methods. The EN and ISO systems are modular, with each specific test method (e.g., bending, swelling, internal bond) published as a separate standard.
≠Specimen dimensions for certain tests differ. For the thickness swelling test (water immersion), IS 2380 specifies a 25x25 mm specimen, while the equivalent EN 317 standard specifies a 50x50 mm specimen.
≠The method for determining surface soundness is different. IS 2380 (Part 13) uses a qualitative tape pull-off test over a cut groove, while EN 311 uses a quantitative method of pulling off a metal block glued to the board surface to measure the force required.
Key Similarities
≈The fundamental physical principles behind the tests, such as the three-point bending test for Modulus of Rupture (MOR) and Modulus of Elasticity (MOE), are identical across all standards.
≈All standards cover a common core set of critical properties for particleboard evaluation, including density, moisture content, thickness swelling, bending strength, and internal bond strength.
≈All standards mandate the conditioning of test specimens in a controlled temperature and humidity environment before testing to ensure repeatable and comparable results.
≈The mathematical formulas used to calculate final values from raw test data (e.g., calculating bending strength from load and specimen geometry) are based on universal engineering principles and are therefore the same.
