Windows and doors - Product standard, performance characteristics - Part 2: Internal pedestrian doorsets
Covers internal doors but is a performance-based standard (acoustics, fire, etc.), not a prescriptive construction guide.
Key Differences
≠IS 1003 is highly prescriptive, dictating exact dimensions, joint types, and construction methods. Modern international standards like BS EN 14351-2 are performance-based, specifying results (e.g., acoustic rating, thermal transmittance) rather than how the door is built.
≠IS 1003 lists specific Indian timber species (e.g., Teak, Deodar, Shisham). International standards like WDMA I.S. 6A list North American species or provide generic grading rules applicable to a wider range of timbers.
≠The Indian standard specifies adhesive requirements by referencing other Indian standards (e.g., IS 851). WDMA I.S. 6A specifies adhesives based on performance types (Type I - Waterproof, Type II - Water-Resistant) linked to specific ASTM test methods, which is a more functional classification.
≠Standard door sizes and thicknesses are country-specific. IS 1003 provides a table of standard sizes common in India (e.g., 2045x900 mm), which differs significantly from the imperial-based standard sizes in US standards or metric sizes in European ones.
Key Similarities
≈All equivalent prescriptive standards (IS 1003, WDMA I.S. 6A, AS 2688) are based on the same fundamental stile and rail construction principle, forming a rigid frame to hold infill panels.
≈All standards emphasize the use of strong, traditional joinery. They specify or recommend mortise and tenon joints, or alternatively dowel joints, for connecting stiles and rails to ensure structural integrity.
≈A common requirement across all standards is that timber panels must be fitted into grooves in a way that allows them to 'float', accommodating natural expansion and contraction due to moisture changes without splitting or warping the door frame.
≈All standards mandate strict quality control for timber, requiring it to be properly seasoned and free from defects like large knots, decay, insect attack, and splits that would compromise the door's strength, stability, or appearance.
