countersink/bore, chamfer and spotface annotation.
i am looking through bs 8888 and its forest of referred standards for an equivalent section to bs 308:part 2 section 7.9 - chamfers, countersinks, counterbores and spotfaces. i would like direction to the correct iso standard if possible. i wish to know the iso method of annotation of these features, and the discussion on using cbore, csk, sface and deep as opposed to the symbols for counterbore, countersink and depth.
thanks, janek
