IS 4116:1988 is the Indian Standard (BIS) for wooden shelving cabinets (adjustable type) -specification. This Indian Standard specifies the requirements for materials, dimensions, construction, and finish of adjustable wooden shelving cabinets commonly used in offices, libraries, and institutional buildings.
wooden shelving cabinets (adjustable type) -Specification
| Parameter | IS Value | International | Source |
|---|---|---|---|
| Design Methodology | Prescriptive: Specifies materials (e.g., Teak wood), joint types, and fixed dimensions. | Performance-based: Specifies test loads and acceptance criteria; material and design are flexible. | ANSI/BIFMA X5.9-2019 |
| Shelf Load Specification | Implicit: Defined by prescribed shelf thickness for a given span (e.g., 25 mm particle board for 710 mm span). | Explicit: Test load applied (e.g., 45 kg distributed over a 900mm wide shelf). | BS EN 14073-3:2004 |
| Maximum Shelf Deflection | Not specified; controlled indirectly by mandatory material thickness. | Specified as a percentage of the span, e.g., deflection ≤ 0.5% of the shelf span. | BS EN 14073-3:2004 |
| Stability Test | Not specified; relies on prescribed construction. | Mandatory test: Unit must not tip when a specified horizontal force (e.g., 89 N / 20 lbf) is applied to the top. | ANSI/BIFMA X5.9-2019 |
| Standard Heights | 1980 mm and 2130 mm | Manufacturer-defined; must pass stability tests for the specified height. | BS EN 14073-2:2004 |
| Material Specification | Restricted to specific timber species (Teak, Sal, Sissoo) and wood-based panels. | Material-agnostic; any material can be used if it passes the performance tests. | ISO 7170:2005 |
