IS 14276:1995 is the Indian Standard (BIS) for cement bonded particle boards -specification. This standard specifies the requirements for cement bonded particle boards (CBPB), a composite material made from wood particles/lignocellulosic material and a cement binder. It covers terminology, materials, dimensions, physical and mechanical properties, and the methods for testing and inspection.

Key Differences
≠IS 14276 specifies a single grade of board, whereas EN 634-2 classifies boards into types based on intended use (dry, humid, external conditions), each with different performance requirements.
≠The Indian standard specifies a mandatory density range of 1000 to 1400 kg/m³. In contrast, EN 634-2 does not mandate a specific density range; it is a value declared by the manufacturer, with properties tested accordingly.
≠For fire performance, IS 14276 refers to Indian test methods like IS 12458. EN standards mandate classification according to the harmonized Euroclass system (e.g., A2-s1, d0) based on EN 13501-1, which is a more detailed and widely recognized system in Europe.
≠EN 634-2 can require more stringent durability tests for boards intended for external use, such as cyclic testing (e.g., V313 test method) to assess freeze-thaw resistance, which is not explicitly required in IS 14276.
Key Similarities
≈Both standards are fundamentally based on the same product definition: a composite panel made from wood particles (or other lignocellulosic material) bonded with Ordinary Portland Cement (OPC).
≈Both IS 14276 and its international counterparts specify minimum requirements for key mechanical properties, including Modulus of Rupture (Bending Strength) and Modulus of Elasticity.
≈All standards mandate testing for moisture resistance, specifically requiring a 24-hour water immersion test to measure thickness swelling and water absorption.
≈Both the Indian and international standards provide strict specifications for dimensional tolerances, including length, width, thickness, and squareness, to ensure product consistency.
