If camber is measured over a strip length not shown in table above, it can be easily converted to an equivalent value for comparison with the standard tolerance, using the formula:

Cu = Ck

x (Lu / Lk)2

 

 

where

Cu = Unknown Camber

 

Ck = Known Camber

 

Lu = Unknown Length

 

Lk = Known Length
