Foreword
IS0 (the International Organization for Standardization) is a worldwide fed-
eration 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, governmental
and non-governmental, in liaison with ISO, also take part in the work. IS0
collaborates closely with the International Electrotechnical Commission
(I EC) 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 International
Standard requires approval by at least 75 % of the member bodies casting
a vote.
International Standard IS0 9339-l was prepared jointly by Technical
Committee lSO/TC 172, Optics and optical instruments, Subcommittee
SC 7, Ophthalmic optics and instruments.
IS0 9339 consists of the following parts, under the general title Optics and
optical instruments - Contact lenses - Determination of the thickness:
Part 7: Rigid contact lenses
Part 2: Hydrogel contact lenses
Annex A forms an integral part of this part of IS0 9339.
