Moulded Raised High-Density Fibre (HDF) Panel Doors
2003 Edition

IS 15380 (2003) does not prescribe exact fixed dimensions or thicknesses for moulded raised HDF panel doors, but industry practices and the standard's parameters suggest: Heavy-duty doors typically have thicknesses between 35 mm and 40 mm, while light-duty doors are generally no thinner than 30 mm. Widths commonly range from 600 mm to 1000 mm and heights from 1980 mm to 2100 mm. Door classification is based on void area: heavy-duty doors feature less than 35% voids, and light-duty doors have up to 65%. Final dimensions should be mutually agreed upon by the purchaser and supplier in accordance with Clause 3.1 of the standard.

Per IS 15380, door frame components such as rails, stiles, and core fillings must be made from timber species with a minimum bulk density of 450 kg/m³ measured at 12% moisture content. These elements should ideally be from a single timber species without joints, except vertical joints permitted within rails and stiles, with widths ranging between 45 mm and 75 mm. The panel skins must be phenolic-bonded High-Density Fibreboard (HDF) with a minimum thickness of 3 mm, featuring a deeply moulded design and wood grain embossing. Door shutters are categorized into heavy duty (void area less than 35%) and light duty (void area up to 65%) types, ensuring durability and aesthetic consistency.

IS 15380 mandates several rigorous tests to verify the durability and functionality of HDF panel doors: Shock resistance testing involves both soft and light body impacts (requiring no visible damage after 15 impacts) and soft and heavy body impacts (withstanding 5 impacts without permanent damage). The slamming test demands the door endure 100 consecutive horizontal slams without visible defects. Additionally, the screw withdrawal resistance test requires a minimum load of 1000 N without surface damage such as delamination or chipping. Buckling tests ensure residual deformation does not exceed 5 mm after unloading, with initial deflections capped at 50 mm, collectively assuring robust mechanical performance.

IS 15380 incorporates environmental compliance by mandating the use of wood sourced exclusively from non-natural forest origins, including industrial and social forestry plantations or shade trees from tea and coffee estates, as per the ECO-Mark criteria established by the Ministry of Environment and Forests and administered by BIS. Manufacturers must submit documentary proof such as certificates or declarations to BIS and obtain environmental clearances from the State Pollution Control Board under applicable water, air, and environment protection legislation. ECO-Mark certified products must be clearly marked to indicate timber species and compliance with ecological standards, promoting sustainable manufacturing and environmental responsibility.

According to IS 15380 Clause 15.1, each HDF panel door shutter must bear clear and permanent markings on any edge, including the manufacturer's name or trademark, construction type (Heavy Duty or Light Duty), size type (Modular or Non-modular), size designation (modular code or actual width and height for non-modular), thickness of the shutter, timber species (mandatory for ECO-Mark certified products), and ECO-Mark criteria where applicable. Additionally, the door may carry the BIS Standard Mark as per Clause 15.2. These markings facilitate traceability, quality assurance, and confirmation of compliance with environmental and product standards.
