Key Differences
≠IS 15380 is highly prescriptive, detailing exact material properties (e.g., HDF density ≥ 800 kg/m³) and dimensions, whereas standards like EN 14351-2 are performance-based, focusing on outcomes like acoustic rating or fire resistance without dictating construction.
≠The Indian standard specifies a timber frame using species like Mango or Pine with a specific moisture content (12 ± 3%). WDMA I.S. 10 allows for a wider range of materials, including composite wood products like LVL or particleboard for stiles and rails.
≠Performance testing protocols are different. IS 15380 references Indian tests from IS 4020 (e.g., Slam Shut Test, Impact Test), while WDMA and EN standards reference their own distinct test suites (e.g., WDMA TM-7 for Cyclic Slam, ASTM E-series, or EN-specific test methods).
≠IS 15380 specifies minimum HDF skin thickness as 2.5 mm. In contrast, the common specification under WDMA guidelines is 1/8 inch, which is approximately 3.2 mm.
Key Similarities
≈All relevant standards are based on the same fundamental construction: two moulded HDF skins bonded to a perimeter frame (stiles and rails) and an infill core.
≈The primary purpose of using moulded HDF skins to affordably replicate the aesthetic of a traditional stile and rail panelled door is a common principle across all standards.
≈Multiple core options are recognized in both IS 15380 and international standards, typically including honeycomb for lightweight applications and solid/tubular particleboard for enhanced acoustic, fire, and durability performance.
≈All standards define acceptable manufacturing tolerances for key dimensions such as height, width, thickness, and squareness to ensure interchangeability and proper fit.
