ISO/DIS 12643-2
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 12643-2 was prepared by Technical Committee ISO/TC 130, Graphic technology.

This third edition of ISO 12643-2 constitutes a technical revision of the second edition (ISO-12643-2:2010).

Significant changes incorporated into this third edition include, but are not limited to, the following:

 addition of Clause 8.12 Large-format ink jet digital printing machines (wide-format ink jet digital printing

machines)
 addition of Clause 9.2 Emergency stop locations

 addition of Clause 14, Verification of safety requirements and/or protective measures

 addition of Clause 15.11 Information for use in the instruction handbook

 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 12643-2. The user is referred to Clause 4 of this standard for guidance in this area.

As from 2014-01-01, ISO 12643-2:2014 will cancel and replace ISO 12643-2:2010. Accordingly, as from

2014-01-01, only ISO 12643-2:2014 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

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 and Clause 5 of this document.

When requirements of this type-C standard are different from those which are stated in type-A or type-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 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 part of ISO 12643, that has been noted.

This part of ISO 12643 was developed to harmonize the requirements of the following US 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

 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
