Tolerances for pressure-locked gratings
Standard tolerances for mesh gratings
This sheet of tolerances applies to pressure-locked mesh gratings with the following specifications:
- Bearing bars 60 x 5 mm
- Mesh size max. 66 mm and min. 11 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 10 meshes) |
f, e, g, ? | : +8 / -0 mm |
Smaller/other tolerances may be applied on request.
