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.
International Standards are drafted in accordance with the rules given in the ISO/IEC Directives, Part 2.
The main task of technical committees is to prepare International Standards. 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.
ISO 27668-1 was prepared by Technical Committee ISO/TC 10, Technical product documentation.
ISO 27668 consists of the following parts, under the general title Gel ink ball pens and refills:
⎯ Part 1: General use
⎯ Part 2: Documentary use (DOC)

Introduction
This part of ISO 27668 is applicable to gel ink ball pens for general use.
Part 2 of ISO 27668 is applicable to gel ink ball pens for documentary 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 over 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.
Furthermore, pens which meet the requirements for documentary use produce lines which are more resistant
to modification (e.g. attempts to falsify a document) than those for general use.
The International Organization for Standardization (ISO) draws attention to the fact that it is claimed that
compliance with this document may involve the use of a patent concerning aqueous gel ink-filled ballpoint
pens.
The holder of this patent right has assured ISO that he is willing to negotiate licences under reasonable and
non-discriminatory terms and conditions with applicants throughout the world. In this respect, the statement of
the holder of this patent right is registered with ISO. Information may be obtained from:
Mitsubishi Pencil Company Limited
Patent Administration Department, 5.23-37, Higashi-ohi
JP-Shinagawa, Tokyo 140-8537

Attention is drawn to the possibility that some of the elements of this document may be the subject of patent
rights other than those identified above. ISO shall not be held responsible for identifying any or all such patent
rights.

3 Terms and definitions
For the purposes of this document, the following terms and definitions apply.
3.1
pen
writing instrument equipped with a feeding system which deposits a writing fluid on a surface
NOTE It is available in refillable or non-refillable (disposable) form.
3.2
ball pen
pen with a writing fluid feeding system based on a rotatable ball writing tip integrated either within the pen
itself or within a refill
3.3
gel ink ball pen
ball pen which deposits a writing fluid whose viscosity decreases markedly with rotation of the ball when
writing and increases back to or near to the original viscosity in non-movement, i.e. when not writing
3.4
cartridge
disposable container for the writing fluid, which is detached when empty and replaced by a (new) full container
NOTE Adapted from ISO 9175-1:1988, definition 3.4.
3.5
refill
identifiable assembly of components, usually removable from a complete pen, with which it is possible to write
independently of the complete pen, but which lacks either characteristics or components which would make it
suitable for use as a pen
3.6
write test machine
device for mechanically generating a line with a pen or refill on a writing surface and which can be adjusted for
⎯ a writing angle between 60° and 90°,
⎯ writing load from 0,1 N to 5 N,
⎯ writing speed between 1 m/min and 10 m/min, and
⎯ line pitch between 1 mm and 5 mm,
with a continuous spiral line (100 mm circumference) and a fixed or rotating motion along the longitudinal axis
of the pen or refill; the writing surface is to be placed on a polished stainless steel plate.
NOTE On request the ISO Central Secretariat will provide a list of suppliers of the write test machine.
