Angles

Equal Angles
Angle : The tolerance on Leg length shall be as follows :

Over (mm) Up to and including (mm) Tolerance
- 45 +1.5 mm
45 100 +2.0 mm
100 - +2 %

Out of Square : The leg of angles shall be perpendicular to each other within a tolerance of + 1.0degree.
The difference between the leg lengths of equal leg angles shall limited to 75 percent of the total tolerance (plus and minus) specified on the leg length.

Equal Angles
Camber : The permissible limits for camber are as follows :-(See Fig 1.4)

Leg Length (mm) Chamber Max. (mm)
Less than 100 o be agreed between the manufacturer and purchaser
Including and over 100 0.2 % of Length
