Foreword
ISO (the International Organization for Standardization) is a worldwide
federation of national standards bodies (ISO member bodies). The work of
preparing International Standards is normally carried out through ISO
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. ISO
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 International
Standard requires approval by at least 75 % of the member bodies casting
a vote.
International Standard ISO 11715 was prepared by Technical Committee
ISO/TC 172, Optics and optical instruments, Subcommittee SC 7,
Ophthalmic optics and instruments.
International Standard ISO 11715 consists of the following parts, under the
general title: Ophthalmic optics — Format of digital data files for data
transfer for the profiling of spectacle lenses
— Part 1: Two-dimensional tracers
— Part 2: Three-dimensional tracers
Annexes A and B of this part of ISO 11715 are for information only.

INTERNATIONAL STANDARD  ISO ISO 11715-1:1998(E)
Ophthalmic optics — Format of digital data files for data transfer
for the profiling of spectacle lenses —
Part 1:
Two-dimensional tracers
1 Scope
This part of ISO 11715 specifies the content and structure of electronic data encoding for two-dimensional tracers.
These data files are used to instruct electronically controlled formerless spectacle-lens profiling machinery.
NOTE The electronic data files are used as an alternative to the mechanical formers specified in ISO 11380.
