Configuration of ends of standard springs:
Wire up to and including 0.8 mm is closed, but unground
Wire from 1.0 mm is closed and ground

d = Wire diameter in mm
De = External diameter (D+d)
D = Mean diameter in mm (De minus d)
Di = Internal diameter in mm (De minus 2xd)
n = Number of effective elastic coils
nt = Coils total (n+2)
Lo = Free unloaded length.
