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.

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);
— 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

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.
NOTE ISO 12100 is the basis for a set of standards which has the following structure: type-A standards
(basic safety standards) giving basic concepts, principles for design and general aspects that can be applied to
machinery, type-B standards (generic safety standards) dealing with one safety aspect or one type of safeguard
that can be used across a wide range of machinery and type-C standards (machine safety standards) dealing
with detailed safety requirements for a particular machine or group of machines.
The machinery concerned and the extent to which hazards, hazardous situations and 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 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.
Where for clarity an example of a preventive measure is given in this document, this should not have
been 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 (see 3.24).
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);
— 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.

For the purposes of this document, the terms and definitions given in ISO 12100:2010 and the
following apply.
3.1
molding machinery
machines used to make sand molds
Note 1 to entry: There are various machinery types which compact granular molding materials 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-, fluidisation- and squeeze molding machines,
— impulse molding machines (the molding sand is compacted by a compression wave which acts on the top of
the sand fill),
— air-flow-squeeze molding machines (similar to impulse-molding machines, except that the compressed air
escapes through nozzles in the pattern plate),
— dynamic squeeze molding machines (compensating pressure squeeze pistons act on the top of the sand fill),
— suction and squeeze molding machines (the pressure differential between the molding box and the pattern
draws in the molding sand),
— vacuum-molding machines (unbonded sand is compacted by vacuum),
— sand slingers (the molding sand is flung into the molding box by the centrifugal force of a rotating wheel).
