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 12643-1 was prepared by Technical Committee ISO/TC 130, Graphic technology.
This third edition of ISO 12643-1 cancels and replaces the second edition (ISO 12643-1:2009). Significant
changes incorporated into this third edition include, but are not limited to the following:
 clarification of requirements for "remote control" versus "remote access";
 addition of Clause 6, Verification of safety requirements and/or protective measures;
 addition of Annex B listing significant hazards and hazard zones; and
 reorganization of clauses to align with requirements in ISO Guide 78, Safety of machinery – Rules for
drafting and presentation of safety standards.
It is the intent of ISO/TC 130 that there be a transition period between the second and third editions of
ISO 12643-1. The user of this part of ISO 12643-1 is referred to Clause 4 of this standard for guidance in this
area.
As from 2014-01-01, ISO 12643-1:2011 will cancel and replace ISO 12643-1:2009. Accordingly, as from
2014-01-01, only ISO 12643-1:2011 will be applicable to new equipment manufactured.
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: Prepress and press equipment and systems
 Part 3: Binding and finishing equipment and systems
 Part 4: Converting equipment and systems
 Part 5: Stand-alone platen presses
Requirements specific to printing prepress and press equipment and systems, binding and finishing
equipment and systems, converting equipment and systems and stand-alone platen presses that are not
included in this part of ISO 12643, are given in subsequent parts of ISO 12643 that contain additional
requirements specific to that type of equipment.

Introduction
This part of ISO 12643 is a type-C standard as stated in ISO 12100.

The machinery concerned and the extent to which hazards, hazardous situations or hazardous events are covered
are indicated in the Scope of this document.

When requirements of this type-C standard are different from those which are stated in type-A or B standards, the
requirements of this type-C standard take precedence over the requirements of the other standards for machines
that have been designed and built according to the requirements of this type-C standard.

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 requirements of the following U.S. and European
safety standards:
 ANSI B65-1 Graphic technology – Safety requirements for graphic technology equipment and systems –
Part 1: General requirements
 ANSI B65-2, Graphic technology — Safety requirements for graphic technology equipment and
systems — Part 2: Prepress and press equipment and systems;
 ANSI B65-3, Graphic technology — Safety requirements for graphic technology equipment and systems –
Part 3: Binding and finishing equipment and systems;
 ANSI B65-5, Safety requirements for graphic technology equipment and systems — Part 5: Stand-alone
platen presses
 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;
 EN 1010-3, Safety of machinery — Safety requirements for the design and construction of printing and
paper converting machines — Part 3: Cutting machines;

following areas:
 mechanical;
 electrical;
 slipping, tripping, falling;
 ergonomics;
 noise;
 UV and laser radiation;
