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

The committee responsible for this document is ISO/TC 39, Machine tools, Subcommittee SC 10, Safety.

It is of relevance, in particular, for the following stakeholder groups representing the market players with

— health and safety bodies (regulators, accident prevention organizations, market surveillance etc.)

Others can be affected by the level of machinery safety achieved by the above-mentioned stakeholder

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

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 the other

standards for machines that have been designed and built according to the requirements of this type-C

This document, in addition to ISO 16092-1, specifies the technical safety requirements and measures to

be adopted by persons undertaking the design, manufacture and supply of pneumatic presses which are

This document deals with all significant hazards relevant for pneumatic presses, when they are used as

intended and under the conditions of misuse which are reasonably foreseeable by the manufacturer (see

Clause 4). All the phases of the lifetime of the machinery as described in ISO 12100:2010, 5.4. have been

For the purposes of this document, the terms and definitions given in ISO 12100:2010, ISO 13849-1:2015,

ISO and IEC maintain terminological databases for use in standardization at the following addresses:

This clause contains all the significant hazards, hazardous situations and events identified by risk

assessment as significant for the machines defined in the scope and which require a specific action to

These hazards are listed in ISO 16092-1:2017, Annex A. Additional hazards are listed in Annex A

Pneumatic presses shall comply with the safety requirements and/or protective/risk reduction measures

of this clause. In addition, the machine shall be designed according to the principles of ISO 12100 for

In addition to requirements given in ISO 16092-1:5.2.3, the following shall apply.

5.2.3.1 Where a pneumatic press is fitted with a pneumatic/hydraulic intensifier, the general

In addition to requirements given in ISO 16092-1: 2017, 5.3.6, the following shall apply.

On presses with an opening stroke length of more than 500 mm and a depth of table of more than 800

mm a mechanical restraint device shall be permanently fixed and integrated with the press. It can be

If an integrated device, when active, cannot be easily seen from the operator's position, an additional

5.3.7 Prevention of unintended gravity fall during production (down-stroking press)

5.3.7.1 Measures shall be provided to prevent unintended gravity fall of the slide/ram in the production

mode with manual or automatic feed or removal (see Tables 1 and 2). Such a fall can be due to a failure

of the pneumatic system, mechanical failure or a failure of the electrical control system.

The restraint devices shall operate automatically and shall be effective whenever the tool is stopped and

5.3.7.2 The restraint device shall consist of one or more of the following measures, provided that they

NOTE 1 See also ISO 16092-1:_, 5.4.1.3 and 5.4.1.4 for the control system requirements to prevent unintended

In addition to requirements given in ISO 16092-1: 2017, 5.4.1, the following control and monitoring

5.4.1.1 For presses pneumatically controlled (see Figures C.4 and C.5) with a stroke length equal or less

than 30 mm, and a maximum press force equal or less than 1000 N, minimum distance shall be calculated

with an overall response time t, where t = 3 x maximum overall closing time (see also annex B)

NOTE The factor 3 is intended to compensate the type of two hand control device selected.

This sub-clause applies to presses fitted with protective devices of the following type:

 two hand control devices used for normal operation. They shall at least correspond to type IIIB of

It shall not be possible for the overall closing time to be exceeded by any adjustment.

5.4.1.2 Power interlocking as defined in ISO 14119:2013, 3.31 may be provided for presses fitted with

interlocking guards. The guard interlocking device shall be positively linked with the valve to control

directly the flow of fluid to and from the cylinder (see Annex C, Figures C.1, C.2 and C.3).

In addition to requirements given in ISO 16092-1: 2017, 5.4.2, the following shall apply.

The means for setting the point at which the safeguarding system is muted during the closing stroke shall

Manual override devices shall not be directly fitted to restraint valves. If manual override devices are

incorporated into other valves for test or maintenance purposes, they shall require the use of a tool to

Safety functions of pneumatic press shall meet the requirements stated in the Tables 1 and 2. Figure 1
