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

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

This document is of relevance, in particular, for the following stakeholder groups representing the

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

machine users/employees (e.g. trade unions, organizations for people with special needs);

This standard does not apply to low pressure die casting machines and/or gravity die casting machines.

This standard deal 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. It 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.
