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.

Introduction
This part of ISO 12757 is applicable to ball point pens for documentary use.
Part 1 of ISO 12757 is applicable to ball point pens for general use.
For documentary use, some requirements, in addition to those for general
use, are necessary
a) to assure the legibility of lettering, and
b) for the handling and storage of documents during long periods of time
(these requirements are often discussed with the archivist).
An example of documentary use is the preparation of documents that are
required as evidence.
iTeh STANDARD
Furthermore, pens whichPREVIEW
meet the requirements for documentary use
produce lines which are more resistant to modification (e.g. attempts to
(standards.iteh.ai)
falsify a document) than those for general use.
