| Parameter | IS Value | International | Source |
|---|---|---|---|
| Design Philosophy | Prescriptive: Specifies materials (e.g., specific timber species) and dimensions (e.g., 25 mm thick planks). | Performance-based: Specifies test outcomes (e.g., must withstand 25,000 load cycles) allowing any material/design that passes. | BS EN 12520:2015 |
| Moisture Content of Timber | 8% to 12% | Not specified; left to manufacturer's discretion to ensure performance. | BS EN 12520:2015 |
| Seat Static Load Test | 180 kgf (approx. 1765 N) applied once for 1 hour. | 1300 N (approx. 133 kgf) applied 10 times for 10 seconds each. | BS EN 12520:2015 |
| Seat Durability (Fatigue) Test | Not specified. | 25,000 cycles with a 1000 N load. | BS EN 12520:2015 |
| Bed Edge Static Load Test | Not specified. | 1000 N load applied to the edge of the bed frame without causing failure. | BS EN 1725:1998 |
| Stability Test Method | Structure is tilted on a platform to 10 degrees; must not topple. | Specific vertical and horizontal forces are applied to edges and surfaces to simulate user actions and check for lifting/overturning. | BS EN 1022:2018 (referenced by EN 12520) |
