Foundry machinery - Safety requirements for high pressure die casting machines (ISO/DIS 23063:2020)

This document applies to high pressure die casting machines:
a)   hot-chamber die casting machines (horizontal or vertical die closing system), and
b)   horizontal/vertical cold-chamber die casting machines (horizontal or a vertical die closing system).
It applies to high pressure die casting units, i.e., high pressure die casting machines (HPDCM) and their interfaces with the following ancillary equipment:
c)   die,
d)   melting, holding and dosing furnaces (see ISO 13577-1),
e)   metal feeding equipment,
f)   inserting and removal devices,
g)   spraying appliances,
h)   heat exchanger for the die.
This ancillary equipment itself is not covered.
Additional risks arising from the material being cast are not covered.
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). 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

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.

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 3.40).

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.

Foundry machinery — Safety requirements for high
pressure die casting machines
1 Scope
This document applies to high pressure die casting machines:
a) hot-chamber die casting machines (horizontal die closing system), and
b) horizontal cold-chamber die casting machines (horizontal die closing system).

It applies to high pressure die casting units, i.e., high pressure diecasting machines (HPDCM) and their

interfaces with the following ancillary equipment:
c) die,
d) melting, holding and dosing furnaces (see ISO 13577-1),
e) metal feeding equipment,
f) inserting and removal devices,
g) spraying appliances,
h) 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 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.
