Foreword
ISO (the International 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 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 standardization.
The procedures used to develop this document and those intended for its further maintenance are
described in the ISO/IEC Directives, Part 1. In particular, the different approval criteria needed for the
different types of ISO documents should be noted. This document was drafted in accordance with the
editorial rules of the ISO/IEC Directives, Part 2 (see www.iso.org/directives).
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 all such patent rights. Details of
any patent rights identified during the development of the document will be in the Introduction and/or
on the ISO list of patent declarations received (see www.iso.org/patents).
Any trade name used in this document is information given for the convenience of users and does not
constitute an endorsement.

Introduction
This document is a type C standard as stated in ISO 12100:2010.
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 (regulators, accident prevention organizations, market surveillance, etc.).
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, e. g. for maintenance (small, medium and large enterprises);

molding machinery
machinery used to make sand molds
Note 1 to entry: There are various machinery types which compact granular molding materials (3.19) including
but not limited to:
— jolt molding machines (compaction by jolting the molding machine deck);
— squeeze molding machines (compaction by squeezing the pattern equipment and the molding sand together);
— jolt and squeeze molding machines;
— shoot-, blow-, fluidization- and squeeze-molding machines;

the sand fill);

draws in the molding sand);

4 Significant hazards and risk assessment
4.1 General
The hazards, hazardous situations and events identified by risk assessment as significant for the
machinery covered by the scope and which require action to eliminate or reduce the risk are listed in
Clause 5 (in particular in Tables 1 to 5).
In general, risks and associated hazards are production and line related. The variety of machinery/lines
cannot be covered in all details in a standard. To deal with this fact, an individual risk assessment of the
machinery/line in question shall be carried out considering the safety requirements of this document.
Significant hazards identified in this individual risk assessment but not dealt with in this document
shall be avoided or reduced by applying the principles of ISO 12100:2010.
ISO 23062:2022(E)
If combinations of machines and/or machine functions described at different parts of this document are
located in the same danger zone, the different measures shall be considered together.
4.2 Interfaces to the linked/integrated equipment
The individual risk assessment shall include the interfaces to the linked/integrated equipment. For this
equipment respective instructions and safety measures including control requirements for interfaces
shall be given in Clause 7.
5 Safety requirements and/or protective/risk reduction measures
5.1 General
5.1.1 Fixed guards
These guards shall be designed in accordance with ISO 12100:2010, ISO 13857:2019 and ISO 14120:2015.
These guards shall also be designed to contain processed materials, fluids or parts that can foreseeable
be ejected or to contain emissions of substances or noise.
Where practical, these guards shall be fixed to the machine structure.
Fixing elements for guards, e.g. screws should stay with the guards or the machine after removal of the
guards.
If floor mounted, these guards shall be securely fixed and have a minimum height of 1,4 m and be
positioned at a sufficient distance from the danger zone in accordance with ISO 13857:2019, Table 1.
The installation of fixed covers is sufficient for safeguarding danger zones when there is no need to
reach in or walk in during normal operation.
5.1.2 Movable guards
a) Detection, monitoring and emergency escape
Movable guards in danger zones with fixed cycle intervention or access (e.g. during loading and
unloading of parts), set-up activities (setting), required periodical manual cleaning or spraying or
troubleshooting, shall incorporate guard interlocking according to ISO 14119:2013.
When the guard is open, the drive power supply for the relevant hazardous movements shall be
disconnected according to 5.1.6.
If trapping can occur behind a movable guard, an emergency escape shall be possible, e.g. providing
panic handle.
b) Interlocking guard with guard locking
An interlocking guard with guard locking effective within the hazardous period shall be used when the
stopping time of the hazardous movement is greater than the access time of a person in reaching the
danger zone.
c) Closing the guards
Closing the guards shall not initiate operation of hazardous movements. If movement was interrupted
by opening of an interlocked guard, the restart shall be performed by actuation from outside the guard.
d) Power operated guards
ISO 23062:2022(E)
Power operated guards shall not create a danger of injury by its own movement. Either the power
provided shall be insufficient to cause injury when contacting the operator, or the guard shall be
provided with a safety trip device to prevent injury.
Actuation of the safety trip device shall stop or reverse the direction of movement of the movable guard.
Power operated guards shall be positioned so that persons cannot remain in the danger zone and
initiate a machine cycle. If trapping behind these guards cannot be avoided, additional detection devices
shall be installed (e.g. contact mat, horizontal ESPD).
5.1.3 Electro-sensitive protective devices (ESPD)
Electro-sensitive protective devices (see IEC 61496-1:2020) shall meet the following requirements:
a) the control system of the machine shall be able to interrupt the hazardous movement in time when
it receives the output signal from such a protective device;
b) they shall switch on if the control system of the machine is connected,
c) they shall be tested at each machine cycle;
d) they shall not act as control devices;
e) they shall not be adjustable neither in the vertical nor in the horizontal direction;
f) they shall be interlocked with the hazardous movements of the machine;
g) the output-signals of such devices shall be independent of the electronic control system of the
machine or shall be connected to failsafe PLC or safety relays;
h) the protective field of such devices shall cover the access area;
i) they shall be positioned so that persons cannot remain between the protective field of the device
and the danger zone and initiate a machine cycle;
j) their position, in relation to the danger zone, shall take into account the machine stopping time, the
approach speed of the operator and the initiation time of the device (see ISO 13855:2010).
