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).

into the core box. Typically used for cold box, hot box and inorganic binder systems.

3.5
coremaking line
equipment used to make ready-to-use single cores and/or core assemblies

Note 1 to entry: A line may consist of,e.g., a sand preparation equipment, core making machine, equipment for

consist of a circular container in which rotating ploughs and/or mill wheels (mullers) are mounted.

3.6
(Continuous) sand mixers

machines in which the sand with bonding agents are continuously mixed and conveyed to the

discharge gate

Note 1 to entry: Typically, the mixing takes place by screw-type mixing principles.

3.7

machines used to aerate the mixed sand

Note 1 to entry: E.g., belt aerators (conveyor belt with impact bars) or wheel aerators (drum with impact bars).

3.8

equipment for the storage and pneumatic conveyance of coal dust or coal dust substitutes and

their mixtures with bonding agents

silos and pipework that are filled pneumatically with such material and by which the material is

supplied pneumatically to the next process step
