IS 10428:1983 is the Indian Standard (BIS) for glossary of terms relating to doors. This standard provides a comprehensive glossary of terms used in the trade and industry related to doors, their components, and hardware. It aims to standardize the vocabulary used by architects, engineers, manufacturers, and contractors to avoid ambiguity.

Practical Notes
! Essential companion document for interpreting door schedules and specifications on architectural drawings.
! Use to clarify communication between architects, contractors, and suppliers to prevent disputes over terminology.
! Crucial for understanding other IS codes related to door manufacturing, installation, and testing.

Key Differences
≠IS 10428:1983 is heavily focused on traditional timber joinery terms (e.g., 'haunching', 'tenon'), reflecting 1980s Indian practice. Modern international standards like BS EN 12519 include terminology for composite materials, uPVC, advanced hardware, and performance characteristics (thermal, acoustic) that are absent from the IS code.
≠The Indian standard uses the term 'Shutter' to refer to the main moving panel of the door. Most international standards, including BS EN 12519 and WDMA standards, use 'Door Leaf' or 'Slab'. 'Shutter' in international parlance usually refers to a window covering or a rolling security door.
≠IS 10428 is a simple alphabetical glossary. BS EN 12519 is systematically structured, grouping terms into sections like 'Types of products', 'Components', 'Materials', and 'Characteristics', which aids in contextual understanding.
≠The IS code contains terms specific to the region, such as 'Fanlight' for a glazed opening over a door, which is an older term. Modern US standards (like WDMA) would use 'Transom' or 'Transom light' as the more common term.
Key Similarities
≈All standards share fundamental terminology for the basic components of a door assembly, including 'Frame', 'Jamb', 'Head', 'Sill' / 'Threshold', 'Stile', and 'Rail'.
≈The basic types of door operation are defined similarly across all standards, with common understanding of terms like 'swinging door', 'sliding door', and 'folding door'.
≈The concept of 'Handing' (designating a door as left-hand or right-hand) is a fundamental principle present in IS 10428 and detailed extensively in international hardware and door standards (e.g., ANSI/BHMA standards), ensuring universal specification for installation.
≈Core joinery and framing terms for panelled doors, such as 'Panel', 'Mullion' (the vertical member between panels or leaves), and 'Lock Rail', have consistent definitions across the IS code and international standards covering traditional wood doors.
