NOTE Preferred lengths are defined in terms of ls and lg:
-- for product grade A, above the discontinous, stepped line:
-- for product B, below this stepped line.

a   p is the pitch of the thread.
b   For lnom≤ 125 mm.
c   For 125 mm < lnom.≤ 200 mm.
d   For lnom > 200 mm.
e   kw.min = 0.7 kmin.
f   lg.max = lnom - b.
    lg.min = lg.max - 5 P.
