18、rnational 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
19、 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 s
20、tandardization. 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
21、 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
22、 all such patent rights. ISO 12643-2 was prepared by Technical Committee ISO/TC 130, Graphic technology. This second edition of ISO 12643-2 constitutes a technical revision of the first edition (ISO 12643-2:2007). Significant changes incorporated into this second edition include, but are not limited
23、 to, the following: inclusion of prepress equipment; requirements for performance levels (PL) or safety integrity levels (SIL) as defined in the current version of ISO 13849-1 and IEC 62061, respectively; addition of requirements for printing plate changes; addition of requirements for emergency sto
24、p on auxiliary draw nips. It is the intent of ISO/TC 130 that both the first and second editions of ISO 12643-2 be applicable until 2011-12-31. ISO 12643-2:2007 is thus provisionally retained until this date. As from 2012-01-01, ISO 12643-2:2010 will cancel and replace ISO 12643-2:2007. Accordingly,
25、 as from 2012-01-01, only ISO 12643-2:2010 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
26、 equipment and systems Part 3: Binding and finishing equipment and systems Part 4: Converting equipment and systems Part 5: Stand-alone platen presses ISO 12643-2:2010(E) vi ISO 2010 All rights reservedIntroduction During the development of this part of ISO 12643, existing relevant standards of othe
27、r 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,
28、 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 standard Printing press systems EN 1010-1, Safety of machinery Safety requirements for the design and construction of prin
29、ting 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 INTERNATIONAL STANDARD ISO 12643-2:2010(E
30、) ISO 2010 All rights reserved 1Graphic technology Safety requirements for graphic technology equipment and systems Part 2: Prepress and press equipment and systems 1 Scope This part of ISO 12643 provides safety requirements specific to prepress and press equipment and systems. It is intended to be
31、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 prepress and press equipment, and the auxiliary equipment integrated into the press control system. 2 Normative references The
