Tolerances for perforated planks
Standard tolerances for plank gratings
This sheet of tolerances applies to plank modules with the following specifications:
- Height max. 70 mm
- Plank element width max. 333 mm and min. 50 mm
- Grating size max. 2.0 m2, where one side measure does not exceed 2000 mm.
The difference between D1 and D2 must not exceed:
| Where: | ± D1 - D2 ≤ 0,012 x S | |
| D1 | : Diagonal measure 1 | |
| D2 | : Diagonal measure 2 | |
| S | : Largest side measure | |
| Largest side measure | Max. D1-D2 |
|---|---|
| 200 | 2,4 mm |
| 400 | 4,8 mm |
| 600 | 7,2 mm |
| 800 | 9,6 mm |
| 1000 | 12,0 mm |
| 1500 | 18,0 mm |
| 2000 | 24,0 mm |
For L/B > 450 mm: 1/150 x L/B, yet max. 8,0 mm
For L/B ≤ 450 mm: max. 3,0 mm
For L/B > 600 mm: 1/200 x L/B, yet max. 8,0 mm
For L/B ≤ 600 mm: max. 3,0 mm
| L & B | : +0 / -4 mm |
| d | : ± 1,5 mm |
| d10 | : ± 4,0 mm (over 4 plank elements) |
| f, e, g, ⌀ | : +8 / -0 mm |
Smaller/other tolerances may be applied on request.
