IS/ISO 12643 : Part 1 : 2023 Graphic Technology - Safety Requirements for Graphic Technology Equipment and Systems - Part 1 General Requirements
NATIONAL FOREWORD
This Indian Standard (Part 1) (First Revision) which is identical to ISO 12643-1 : 2023 'Graphic technology - Safety requirements for graphic technology equipment and systems - Part 1: General requirements', issued by the International Organization for Standardization (ISO) was adopted by the Bureau of Indian Standards on recommendation of the Printing Machinery Sectional Committee and approval of the Mechanical Engineering Division Council.
This standard was first published in 2014. In this revision the following major changes have been incorporated:
a) In 5.3.2, the requirements for guards (fixed guards with hinges, inclusion of examples of fastening devices, e.g. rotary clamping closures, adaptation to ISO 13857 : 2019) have been revised;
b) Former 6.5.5 (interlocking with guard locking) has been deleted (related machine-specific requirements are provided in the subsequent parts of ISO 12643 series);
c) In 5.3.6, the requirements for hold-to-run controls have been revised;
d) In 5.3.8, the requirements for reel unwinding devices, rewinding devices and reel transport systems have been revised (monitoring of the chucking cones, adaptation of the requirements to smaller machinery, monitoring of the circumferential speed with regard to overwinding, area protection, protective devices at rewinding devices with manual or automatic reel change);
e) In 5.3.10, the requirements for pile carrier movements at feeders and deliveries have been revised;
f) In 5.4.2, the requirements for explosion and fire protection have been revised;
g) In 5.4.8.2, the requirements for UV radiation to the cited EN 12198-1 : 2000 have been adapted: no distinction between UVA and UVB/UVC anymore, reference to effective UV radiation;
h) A new sub clause (5.4.10) about doctor blades has been added;
j) In 5.7.2, information that touch sensitive control devices shall not be used for initiating safety functions has been clarified;
k) In 5.7.2.3, colours for controls have been adapted;
m) In 5.7.2.5.1.2, the comprehensive requirements for emergency stop devices have been replaced by reference to IEC 60204-1 : 2016/AMD 1 : 2021 and ISO 13850 : 2015 (references to safety functions of IEC 61800-5-2, for example, STO);
n) In 5.7.6, the requirements of ESPDs to IEC 61496-1 : 2020 and IEC 61496-2 : 2020 has been adapted; likewise, the heights of the light beams for a 3-beam solution have been adapted;
p) In 5.8, the requirements to fixed and portable control station have been adapted;
q) In 5.10, the requirements for control systems has been revised: - the term 'irreversible injuries' has been introduced;
r) An overview table of the performance levels defined in the document has been inserted;
s) In 6, detailed listings of the validation methods for all safeguarding measures has been added;
t) In 8.3.1, the requirements for instruction handbook with regard to noise emission values and hearing protection have been amended;
u) Annex A has been revised and has been converted to a normative annex;
v) The list of significant hazards has been moved to Annex B;
w) The noise comparison values in Annex D has been added;
x) A normative Annex F on occurrence of a hazardous explosive atmosphere has been added; and
y) An informative Annex G on the relationship between protection zones against explosion and equipment to be used has been added.
This standard is published in various parts. Other parts in this series are:
Part 2 Prepress and press equipment and systems
Part 3 Binding and finishing equipment and systems
Part 4 Converting equipment and systems
Part 5 Manually-fed stand-alone platen presses
The text of ISO standard has been approved as suitable for publication as an Indian Standard without deviations. Certain terminologies and conventions are, however, not identical to those used in Indian Standard. Attention is particularly drawn to the following:
a) Wherever the words 'International Standard' appear, referring to this standard, they should be read as 'Indian Standard'; and
b) Comma (,) has been used as a decimal marker, while in Indian Standards, the current practice is to use a point (.) as the decimal marker.
