h) In 7, requirements for automatic and semi-automatic printing plate changing have been revised;
j) In 8.2 and 8.3, the requirements for fire and explosion protection have been revised;
k) In 8.3.2, 8.3.3, 8.7.2, 8.7.3, 15.9 and B.6.2.2.2, flash point to Globally Harmonised System (GHS, flammable liquids 60 °C) have been adapted;
m) Addition of 8.12 and 15.11 with requirements for large-format inkjet digital printing machines (wide-format inkjet digital printing machines);
n) A new subclause 8.13 on dust protection requirements for web offset printing presses has been added;
p) A new subclause 8.14 on Emergency stop devices and stop/safe pushbuttons at stationary control stands of web offset printing presses has been added;
p) The clause on alternative controls for stop/safe function on sheet-fed presses has been deleted;
q) In 9.4, a requirement for inkjet printing systems in connection with emergency stop has been added;
r) The clause on colours for manual controls has been deleted;
s) The list of significant hazards has been moved to an informative Annex A;
t) The annex on protection zones against explosion has been moved to ISO 12643-1 : 2023;
u) In Annex B, the following have been adapted:
1) Selected measurement locations for the measurement of emissions of ink mist, varnish mist, ammonia, VOC IPA, VOC hydrocarbon compounds;
2) The limit value for ammonia at measurement location 2;
3) The measurement conditions for VOC IPA (6 percent IPA in dampening water), VOC hydrocarbon compounds (measurement during entire washing program).
This standard is published in various parts. Other parts in this series are:
Part 1 General requirements
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.
