Foreword
IS0 (the International Organization for Standardization) is a worldwide
federation of national standards bodies (IS0 member bodies). The work
of preparing International Standards is normally carried out through IS0
technical committees. Each member body interested in a subject for
which a technical committee has been established has the right to be
represented on that committee. International organizations, govern-
mental and non-governmental, in liaison with ISO, also take part in the
work. IS0 collaborates closely with the International Electrotechnical
Commission (IEC) on all matters of electrotechnical standardization.
Draft International Standards adopted by the technical committees are
circulated to the member bodies for voting. Publication as an lnter-
national Standard requires approval by at least 75 % of the member
bodies casting a vote.
International Standard IS0 9519 was prepared by Technical Committee
lSO/TC 8, Shipbuilding and marine structures.
This first edition cancels and replaces the first edition of IS0 5487:1981:
basically a technical revision of this, it retains the main dimensions of
rungs for superstructures (which accord with the IL0 Minimum require-
ments for hold ladders) but extends it, notably in the code letters, more
precise material requirements (clause 4), surface finish (5.2) and toler-
ances (6.3).
