IS 3497:1992 is the Indian Standard (BIS) for steel wardrobes (adjustable type)-specification. This Indian Standard specifies the requirements for materials, dimensions, manufacture, and finish for adjustable-type steel wardrobes used for storage in residential, commercial, and institutional buildings.
Steel wardrobes (adjustable type)-Specification
BIM-relevant code. See the BIM Hub for ISO 19650, IFC, and LOD/LOIN frameworks used alongside it.
| Parameter | IS Value | International | Source |
|---|---|---|---|
| Body Sheet Thickness | Not less than 0.80 mm CRCA steel sheet | Not specified; performance-based. Must pass strength and durability tests. | ANSI/BIFMA X5.9-2019 |
| Door Sheet Thickness | Not less than 1.00 mm CRCA steel sheet | Not specified; performance-based. Must pass door slam and cycle tests. | ANSI/BIFMA X5.9-2019 |
| Shelf Load Test | 40 kg uniformly distributed load (UDL) for 24 hours. Max deflection 1/200 of span. | Load calculated based on storage volume (e.g., 75 lbs/ft³), often resulting in 50-70 kg UDL. Max deflection criteria apply. | ANSI/BIFMA X5.9-2019 |
| Stability (Tip-Over) Test | Not specified in the standard. | Mandatory. Unit must not tip when a specified horizontal force (e.g., 89 N) is applied to the top and a vertical load is applied to an open door. | BS EN 14073-2:2004 |
| Door Durability | No cyclic test specified. Focuses on hinge construction. | Must withstand a specified number of operational cycles (e.g., 20,000 cycles) without functional failure. | ANSI/BIFMA X5.9-2019 |
| Locking Mechanism | Prescribed as a '6-lever unpickable lock'. | Performance-based. Lock and mechanism must withstand specified torque and pull forces without failure. | ANSI/BIFMA X5.9-2019 |
| Surface Pre-treatment | Phosphating treatment as per IS 6005. | Not specified, but finish must pass performance tests like adhesion (ASTM D3359) and corrosion resistance (e.g., salt spray test ASTM B117). | General BIFMA/ASTM reference |
