Prefered lengths are defined in terms of l_s and l_g: --- product grade A, above the discontinuous, stepped line; --- product grade B, below this stepped line. Notes a) P is the pitch of the thread. b) FOR l_nom ≤ 125 mm. c) For 125 mm < l_nom ≤ 200 mm. d) For l_nom > 200 mm. e) k_w,min = 0.7 k_min f)l_{g, min} = l_nom - b l_s,min = l_g,max - 5P
