Graphic technology -- Safety requirements for printing press systems
ISO 12648:2002 applies to printing press systems, including auxiliary equipment and finishing machines, in which all the machine actuators (e.g. drives) of the equipment in the system are controlled by the same control system.
It is applicable only to systems in which a printing press is part of the system. In cases where a binding/finishing system is not integrated with a printing press, ISO 12649 will apply.
ISO 12648:2002 provides safety requirements for the design and construction of the classes of machines listed in Clause 2. It addresses recognized hazards specific to printing press systems in the following areas:
mechanical;
electrical;
slipping, tripping, falling;
ergonomics;
noise;
radiation;
fire and explosion;
thermal;
emissions.
ISO 12648:2002 applies to new machines (see Clause 2) manufactured after December 31 of the year following the year of publication of this standard.

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.
Attention is drawn to the possibility that some of the elements of this document may be the subject of patent
rights. ISO shall not be held responsible for identifying any or all such patent rights.
ISO 12648 was prepared by Technical Committee ISO/TC 130, Graphic technology.

Introduction
During the development of this International Standard, existing relevant standards of other countries were
taken into consideration. An effort has been made to harmonize the requirements of all 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 International Standard, that has been noted.
This International Standard has taken into consideration material contained in ANSI B65.1-1995 Safety
standard — Printing press systems, prEN 1010-1, Technical safety requirements for the design and
construction of printing and paper converting machines — Part 1: Common requirements, and prEN 1010-2,
Technical safety requirements for the design and construction of printing and paper converting machines —
Part 2: Printing and varnishing machines including pre-press machinery.

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.
Attention is drawn to the possibility that some of the elements of this document may be the subject of patent
rights. ISO shall not be held responsible for identifying any or all such patent rights.
ISO 12648 was prepared by Technical Committee ISO/TC 130, Graphic technology.

Introduction
During the development of this International Standard, existing relevant standards of other countries were
taken into consideration. An effort has been made to harmonize the requirements of all 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 International Standard, that has been noted.
This International Standard has taken into consideration material contained in ANSI B65.1-1995 Safety
standard — Printing press systems, prEN 1010-1, Technical safety requirements for the design and
construction of printing and paper converting machines — Part 1: Common requirements, and prEN 1010-2,
Technical safety requirements for the design and construction of printing and paper converting machines —
Part 2: Printing and varnishing machines including pre-press machinery.

Graphic technology — Safety requirements for printing press
systems
1 Scope
This International Standard applies to printing press systems, including auxiliary equipment and finishing
machines, in which all the machine actuators (e.g. drives) of the equipment in the system are controlled by the
same control system.
It is applicable only to systems in which a printing press is part of the system. In cases where a
binding/finishing system is not integrated with a printing press, ISO 12649 will apply.
This International Standard provides safety requirements for the design and construction of the classes of
machines listed in Clause 2. It addresses recognized hazards specific to printing press systems in the
following areas:
mechanical;
electrical;
slipping, tripping, falling;
ergonomics;
noise;
radiation;
fire and explosion;
thermal;
emissions.
This International Standard applies to new machines (see Clause 2) manufactured after December 31 of the
year following the year of publication of this International Standard.
2 Classifications
2.1 Machines for producing printing by various processes
relief (letterpress, flexographic);
offset (lithographic);
gravure (rotogravure, intaglio);
