IS 7070:1988 is the Indian Standard (BIS) for wooden shelving racks, adjustable and non-adjustable type. This standard specifies the requirements for materials, dimensions, construction, finish, and performance of wooden shelving racks of both adjustable and non-adjustable types. It is intended for use in offices, libraries, and for general storage purposes. The code includes load testing procedures to ensure the structural integrity and durability of the racks.

| Parameter | IS Value | International | Source |
|---|---|---|---|
| Shelf Static Load Test | 40 kg/m per 100mm depth for 24 hrs. E.g., a 1m span, 300mm deep shelf must hold 120 kg. | Load of 66 lbs/ft² (approx. 322 kg/m²) for 1 hour. | ANSI/BIFMA X5.9-2019 |
| Maximum Shelf Deflection | Shall not exceed 1/200 of the span after 24 hours under load. | Shall not exceed L/200 (or 0.5% of shelf length) after 1 hour under load. | ANSI/BIFMA X5.9-2019 |
| Stability Test (Horizontal Force) | Unit must withstand a horizontal force of 500 N (~51 kgf) at 1.8m height without toppling. | Unit must withstand a horizontal force of 200 N (~20 kgf) at the highest reachable point (max 1.5m) without toppling. | EN 14073-2:2004 |
| Timber Moisture Content | Shall not exceed 12% at the time of fabrication. | Not specified in performance standards; considered a manufacturing process control. Good practice is typically 6-11%. | General Woodworking Practice (not a standard) |
| Standard Rack Height | 1800, 2100, or 2400 mm. | Not specified; determined by manufacturer and ergonomic considerations. Common heights are 1830 mm (72") and 2134 mm (84"). | General Commercial Practice |
| Upright Material & Size | Specified timber (e.g., Teak) with minimum section sizes like 70x40 mm. | Not specified. Any material and size that can pass the mandatory strength and stability tests is acceptable. | ISO 7170:2023 |
