0 Introduction
This document is a type-C standard as stated in EN 1070.
The machinery concerned and the extent to which hazards, hazardous situations and events are covered are
indicated in the scope of this document.
As with presses for forming hot metal, the result of the risk assessment is that due to the heat of the material
processed and the need for the use of auxiliary aids, such as tongs, during work in the danger zone of the closing
mould, there is typically no significant risk from the closing movement of the mould parts during the normal shaping
process of hot glass. There are hazards at other times, e.g. movements initiated by personnel or failure of the
controls during setting. Safety requirements laid down in this standard relative to the movements of mould parts
therefore deal especially with the manual control of glass presses for setting operations as defined in 3.7.
When compiling this standard, it was assumed that:
 movements of mould parts (plunger and ring) in hydraulically and pneumatically operated presses result from
the movements of the rod or of the cylinder;
 harmful materials such as asbestos and toxic substances are not used;
 noise generated by the glass press is itself not a significant hazard, but noise by air-cooling of hot articles and
the mould and by pneumatic waste ejection with air from an outside system may cause the necessity of
wearing ear protection by the operator.
 glass presses are not intended to be used in potentially explosive atmospheres.
When provisions of this type-C standard are different from those which are stated in type-A or -B standards, the
provisions of this type-C standard take precedence over the provisions of the other standards for machines that
have been designed and built according to the provisions of this type-C standard.
1 Scope
1.1 This standard contains the requirements for the design and installation of glass presses including equipment
for feeding of portions of molten glass to the mould, loading equipment and equipment for discharging articles
(take-out) when these are integral parts of the presses.
1.2 This standard deals with all significant hazards, hazardous situations and events relevant to glass presses
when they are used as intended and under the conditions foreseeable by the manufacturer (see clause 4). This
standard specifies the appropriate technical measures to eliminate or reduce risks which can arise from these
significant hazards.
1.3 This standard does not deal with forming machines for hollow glass where the press operation is only a part
of the hot-forming process, such as the press/blow process of IS machines (see prEN 13042-3).
1.4 This standard does not deal with gob feeders (see prEN 13042-1) and handling machines for feeding (see
prEN 13042-2) which are self-standing machines and dealt with in other standards of the series regarding
machinery used in the production of hollow glass.
1.5 This document is not applicable to presses which are manufactured before the date of publication of this
document by CEN.
1.6 This standard deals only with hazards arising from the application of components which may be used in
glass presses, such as motors and continuous handling equipment. More particular safety requirements are dealt
with within standards more specific to that component, including noise.

system.
