Part 3:
Safety requirements for hydraulic presses
1 Scope
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 hydraulic presses which are
intended to work cold metal or material partly made up of cold metal.
The presses covered by this document range in size from small high-speed machines with a single
operator producing small workpieces to large relatively slow-speed machines with several operators
and large complex workpieces.
This document deals with all significant hazards relevant for hydraulic 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 taken into consideration.

ISO 16092-3:2017(E)
4 List of significant hazards
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
eliminate or reduce the risk.
These hazards are listed in ISO 16092-1:2017, Table 1. Additional hazards are listed in Annex A,
Table A.1.
5 Safety requirements and/or measures
5.1 General
Hydraulic 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
relevant but not significant hazards which are not dealt with by this document.
5.2 Basic design considerations
5.2.1 Hydraulic and pneumatic systems — Common features
ISO 16092-1:2017, 5.2.1 shall apply.
5.2.2 Pneumatic systems
ISO 16092-1:2017, 5.2.2 shall apply.
5.2.3 Hydraulic systems
In addition to requirements given in ISO 16092-1:2017, 5.2.3, the following shall apply.
5.2.3.1 Controlled gravity descent may be a deliberate design feature to facilitate rapid closing of
the tools.
In such a case, all the oil in the cylinder supporting the slide/ram shall be passed through the main
control valve or valves in a redundant and monitored system (see Table 1 and/or Table 2).
5.2.3.2 The circuit shall be protected by pressure limiting valves. These valves shall not be capable
of alteration without the use of a tool. Also, they shall be set at a pressure which is no more than 10 %
higher than the maximum operating pressure.
5.2.3.3 For down-stroking presses, provision shall be made to protect the cylinder and components
containing the fluid in the lower part of the cylinder from damage due to pressure intensification. A relief
valve used for this purpose shall be direct operated, sealed and locked against unauthorised adjustment,
and shall be set at a pressure at least 10 % above the maximum system pressure so that it only opens in
the case of a fault. The components it protects shall be designed to withstand the pressure at which the
valve is set. The relief valve shall be constructed so that, if a single break in the spring occurs, the space
between the windings remains less than one wire thickness. The spring shall be guided so as to maintain
the function of the relief valve.
5.2.4 Electric systems
ISO 16092-1:2017, 5.2.4 shall apply.

5.3.2 Safeguarding measures
In addition to requirements given in ISO 16092-1:2017, 5.3.2, the following shall apply.
Slow closing speed used in combination with hold-to-run control devices shall not exceed 10 mm/s.
The speed shall not be limited by adjustment of variable parameters (see Tables 1, 2 and Annex F). The
hold-to-run control device shall consist of a single button/foot-pedal and shall fulfil the requirements
of IEC 60947-5-8. For foot-pedals, the force shall not exceed 350 N for switching from position 2 to
position 3.
5.3.3 Other safety requirements
ISO 16092-1:2017, 5.3.3 shall apply.
5.3.4 Release of trapped persons between the tools
ISO 16092-1:2017, 5.3.4 shall apply.

5.3.6 Prevention of gravity fall during maintenance or repair
In addition to requirements given in ISO 16092-1:2017, 5.3.6, the following shall apply.
5.3.6.1 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 manually operated.
If an integrated device, when active, cannot be easily seen from the operator's position, an additional
clear indication of the position of the device shall be provided.
5.3.6.2 Where the restraint device is provided as protection during production and is mechanically
linked to a main guard which needs to be removed for maintenance purposes, additional mechanical
restraint devices, which can be manually positioned where necessary, shall be provided.
5.3.7 Prevention of unintended gravity fall during production (down-stroking press)
5.3.7.1 Measures shall be provided to prevent an 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 hydraulic system, mechanical failure or a failure of the electrical control system. In this case:
— a mechanical restraint device, or
— a hydraulic restraint device, as defined in 5.3.7.2, or
— a combination of a single valve hydraulic restraint device and a mechanical restraint device
shall be provided.
ISO 16092-3:2017(E)
The restraint devices shall operate automatically and shall be effective whenever the tool is stopped
and operator access to the tools is possible.
5.3.7.2 Where mechanical restraint devices are not used, hydraulic restraint devices shall consist
of either:
a) two separate hold-up or return cylinders each with a hydraulic restraint valve, capable of
independently holding the slide/ram, or
b) two hydraulic restraint valves, one of which is fitted as close as possible to the cylinder outlet,
using flanged or welded pipework, capable of holding the slide/ram.
NOTE Further requirements are given in Tables 1 and 2.
5.3.7.3 On a press made solely for:
— automatic operation in conjunction with interlocking guards with guard locking, or
— use with closed tools, or
— use with fixed enclosing guards,
a single valve hydraulic restraint device, or a mechanical restraint device, shall be provided as a
minimum.
5.3.7.4 There shall be a system for monitoring that the restraint system as defined in 5.3.7.1 is
functioning correctly, and no press stroke shall be possible after any part of the system has failed (see
Tables 1, 2 and Annex D, Figure D.1).
5.3.7.5 Requirements for prevention of unintended strokes are laid down in Tables 1, 2 and ISO 16092-
1:2017, 5.4.1.2 to 5.4.1.4.
5.4 Control and monitoring system
5.4.1 Control and monitoring functions
In addition to requirements given in ISO 16092-1:2017, 5.4.1, the following control and monitoring
functions shall apply.
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 manually actuated
valve to reverse or cut off directly the flow of hydraulic fluid to and from the actuator.
NOTE For examples of power interlocking, see Figure D.2 and ISO 14119.
5.4.2 Muting
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 be:
— a position signal, and
— a pressure signal or suitable alternative, signals which actuate when the tools are closed and the
machine begins to apply the force.
