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 12643-2 was prepared by Technical Committee ISO/TC 130, Graphic technology.
This first edition, together with ISO 12643-1, cancels and replaces ISO 12648:2006, which has been
technically revised.
ISO 12643 consists of the following parts, under the general title Graphic technology — Safety requirements
for graphic technology equipment and systems:
⎯ Part 1: General requirements
⎯ Part 2: Press equipment and systems
⎯ Part 3: Binding and finishing equipment and systems

Introduction
During the development of this part of ISO 12643, existing relevant standards of other countries were taken
into consideration. An effort has been made to take into consideration the requirements of many countries,
recognizing that national standards or laws may dictate national requirements. In cases where it was known
that there is a national requirement that differs from this part of ISO 12643, that has been noted.
This part of ISO 12643 was developed to harmonize the following U.S. and European safety standards:
⎯ ANSI B65.1, Graphic technology — Safety standard — Printing press systems
⎯ EN 1010-1, Safety of machinery — Safety requirements for the design and construction of printing and
paper converting machines — Part 1: Common requirements
⎯ EN 1010-2, Safety of machinery — Safety requirements for the design and construction of printing and
paper converting machines — Part 2: Printing and varnishing machines including pre-press machinery
The International Organization for Standardization (ISO) and the International Electrotechnical Commission
(IEC) draw attention to the fact that it is claimed that compliance with 5.7.2 of this part of ISO 12643 may
involve the use of one or more patents concerning the use of electro-sensitive protective devices (ESPDs) in
the delivery area. The patents identified are:
⎯ German Patent DE 103 10 236 B3
⎯ PCT patent application WO 2004/078626 A1
ISO takes no position concerning the evidence, validity and scope of this patent right.
The holders of this patent right have assured ISO that they declare not to enforce any rights resulting from the
patents identified above against any third parties in any countries that intend to comply with the ISO/TC 130,
CEN/TC 198, ANSI B65 standards, or any other local or regional standards that use the ISO/TC 130
standards or the relevant parts thereof or any derivative standards thereof. In this respect, the statement of
the holders of this patent right is registered with ISO. Information may be obtained from:

rights other than those identified above. ISO shall not be held responsible for identifying any or all such patent
rights.

Graphic technology — Safety requirements for graphic
technology equipment and systems —
Part 2:
Press equipment and systems
1 Scope
This part of ISO 12643 provides requirements specific to press equipment and systems. It is used in
conjunction with the general requirements given in ISO 12643-1.
This part of ISO 12643 provides additional safety requirements for the design and construction of new press
equipment and the auxiliary equipment integrated into the press control system.

3 Terms and definitions
For the purposes of this document, the terms and definitions given in ISO 12643-1, ISO 13849-1:1999 and the
following apply.
3.1
access height in the sheet-fed press delivery zone
dimension of the maximum opening into the area below the sheet gripper, measured between the access level
(floor, fixed platform or footboard) and the lower edge of fixed machine parts (e.g. fixed guard, fixed cover,
fixed parts such as a sheet stop)
See Figure 1.
3.2
alcohol dosing equipment
device(s) used to regulate the amount of alcohol in the dampening water of offset printing presses
