Introduction
This document is a type C standard as stated in ISO 12100.
This document is of relevance, in particular, for the following stakeholder groups representing the market
players with regard to machinery safety:
— machine manufacturers (small, medium and large enterprises);
— health and safety bodies (e.g. regulators, accident prevention organisations, market surveillance).
Others can be affected by the level of machinery safety achieved with the means of the document by the
above-mentioned stakeholder groups:
— machine users/employers (small, medium and large enterprises);
— machine users/employees (e.g. trade unions, organizations for people with special needs);
— service providers, for example, for maintenance (small, medium and large enterprises);
— consumers (in case of machinery intended for use by consumers).
The above-mentioned stakeholder groups have been given the possibility to participate at the drafting
process of this document.
The machinery concerned and the extent to which hazards, hazardous situations or hazardous events are
covered are indicated in the Scope 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.
Where, for clarity, an example of a preventive measure is given in this document, this should not be
considered as the only possible solution. Any other solution leading to the same risk reduction is permissible
if an equivalent level of safety is achieved.
It is assumed that the machinery according to the scope is operated and maintained by trained personnel.

This document applies to high pressure die casting units, i.e. high pressure die casting machines (HPDCM),
and their interfaces with the following ancillary equipment:
a) die;
b) melting, holding and dosing furnaces (see ISO 13577-1:2016);
c) metal feeding equipment;
d) inserting and removal devices;
e) spraying appliances;
f) heating and cooling devices for the die.
This ancillary equipment itself is not covered.
Additional risks arising from the material being cast are not covered.
This document does not apply to either low pressure die casting machines or gravity die casting machines,
or both.
This document deals with all significant hazards, hazardous situations and events relevant to pressure die
casting machines when used as intended and under conditions of misuse which are reasonably foreseeable
by the manufacturer (see Clause 4).
This includes hazards coming from intentional interactions as well as unintentional but foreseeable
interactions between movable parts of the machine and persons.
This document provides the requirements to be met by the manufacturer to ensure the safety of persons
and property during transport, commissioning, use, de-commissioning and maintenance periods, as well as
in the event of foreseeable failures or malfunctions that can occur in the equipment.

area between the moving platen (3.16) and the cylinder platen (3.26)
3.28
injection drive area
area between the fixed platen (3.24) and the shot cylinder
3.29
closing safety device
device actuated by the movable guard which prevents the die from closing if a failure occurs in the control system
3.30
setting mode
operating mode where any step in the process can be selected and hand operated in any sequence with
restricted operation of the safety functions
EXAMPLE To perform individual steps of the process (not necessarily in operating cycle sequence), like
changing a die.
3.31
manual mode
operating mode where the individual steps in the machine cycle are hand initiated
EXAMPLE To perform the individual steps of the process (only in the sequence which is fixed by the program),
such as to finish the casting cycle or to run the casting cycle in order to examine or to look for faults.
3.32
semi-automatic mode
operating mode where each cycle is hand initiated but thereafter automatically proceeds to completion
EXAMPLE To produce castings in which at least one of the steps of the process which is performed outside the
machine is executed by the operator (3.35).
3.33
automatic mode
operating mode where the completion of a casting cycle initiates the next casting cycle
EXAMPLE To continuously produce castings with any external process steps being automatically carried out by
ancillary device.

3.34
machine-setter
designated person, trained and skilled to carry out adjusting, die changing, setting and starting-up the die
casting (3.2) process
3.35
operator
designated person trained and skilled to run the die casting machine (3.3)
3.36
access door
door of the distance guards of a die casting cell (3.4)
3.37
inspection
measure to observe and assess the current condition as well as fault finding
Note 1 to entry: Measures (e.g. measuring, testing, diagnostics) including the determination of the causes of wear or
damage and the derivation of the necessary consequences for the continued use.
Note 2 to entry: This definition does not cover “material inspection”.
3.38
maintenance
combination of service, inspection (3.37), reconditioning and functional test of the equipment
Note 1 to entry: The purpose is to preserve the working condition or returning to this condition so that the required
function can be performed (including safety requirements).
Note 2 to entry: Service is a measure to maintain the nominal condition. The nominal condition can be maintained
in general without dismantling/disassembling major parts of the equipment (e.g. cleaning, lubrication of the work
equipment as well as addition or replacement of agents) or by replacing tools or operational changing parts.
Note 3 to entry: Reconditioning is a measure to return to the nominal condition. Foreseeable measures to replace
worn parts or parts having expired the foreseen lifetime (can require dismantling/disassembling). These parts should
meet manufacturers' specification.
Note 4 to entry: A functional test is checking the functionality of the exchanged or repaired parts. Adjustment work
can be required (e.g. test runs, verifying safety functions).
3.39
dry cycle
operation mode of the die casting machine (3.3), with all movements of the die casting machine, which are
typical for a production cycle [e.g. with injection cylinder movements but without molten metal (3.7) and
with die opening, die closing and interlocking using a die or a test block (3.40) mounted in the die area (3.25)]
3.40
test block
object for simulating the presence of a die in the die area (3.25) of the machine
3.41
performance level
PL
discrete level used to specify the ability of safety-related parts of control systems to perform a safety
function under foreseeable conditions
Note 1 to entry: The symbols “a”, “b”, “c”, “d”, and “e” in this document indicate the performance level of safety-related
components with respect to their average probability of dangerous failure. More information on these symbols is
given in ISO 13849-1.
