INTERNATIONAL STANDARD ISO 16092-1:2017(E)
Machine tools safety — Presses —
Part 1:
General safety requirements
1 Scope
This document specifies technical safety requirements and measures to be adopted by persons
undertaking the design, manufacture and supply of presses which are intended to work cold metal or
material partly of cold metal, but which can be used in the same way to work other sheet materials (e.g.
cardboard, plastic, rubber, leather, etc.).
NOTE 1 The design of a machine includes the study of the machine itself, taking into account all phases of
the “life” of the machine mentioned in ISO 12100:2010, 5.4, and the drafting of the instructions related to all the
above phases.
The requirements in this document take account of intended use, as defined in ISO 12100:2010, 3.23,
as well as reasonably foreseeable misuse, as defined in ISO 12100:2010, 3.24. This document presumes
access to the press from all directions, deals with all significant hazards during the various phases of
the life of the machine described in Clause 4, and specifies the safety measures for both the operator
and other exposed persons.
NOTE 2 All significant hazards means those identified or associated with presses at the time of the publication
of this document.
This document applies to presses which can function independently and can also be used as a guide for
the design of presses which are intended to be integrated in a manufacturing system.
The covered presses transmit force mechanically to cut, form, or work cold metal or other sheet
materials by means of tools or dies attached to or operated by slides/ram in 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 workpieces.
This document does not cover machines whose principal designed purpose is:
a) metal cutting by guillotine;
b) attaching a fastener, e.g. riveting, stapling or stitching;
c) bending or folding by press brakes or folding machines;
d) straightening;
e) turret punch pressing;
f) extruding;
g) drop forging or drop stamping;
h) compaction of metal powder;
i) single purpose punching machines designed exclusively for profiles, e.g. used in the construction
industry;
j) spot welding;
k) tube bending;
ISO 16092-1:2017(E)
l) working by pneumatic hammer.
This document does not cover hazards related to the use of presses in explosive atmospheres.
This document covers the safety requirements related to the use of programmable electronic
systems (PES) and programmable pneumatic systems (PPS).
This document is not applicable to presses which are manufactured before the date of its publication.
This document deals with the common significant hazards, hazardous situations and events relevant
to presses and ancillary devices which are intended to work cold metal or material partly of cold metal
(see Clause 4). This document defines the common safety requirements for presses defined in this
clause and shall be used in connection with other parts of the ISO 16092 series.
Specific hazards which are related to the type presses used are dealt with in ISO 16092-2, ISO 16092-3
and ISO 16092-4.

3.4.1.5
single cycle with AOPD single break
PSDI single break
operating mode (3.4.1) where an AOPD (3.2.18) is used for cycle (3.4.4) initiation after clearing the AOPD
following a single interruption for manual loading and unloading
Note 1 to entry: PSDI means presence-sensing device initiation.
3.4.1.6
single cycle with AOPD double break
AOPD double break
PSDI double break
operating mode (3.4.1) where an AOPD (3.2.18) is used for cycle (3.4.4) initiation after clearing the AOPD
following a double interruption for manual loading and unloading
Note 1 to entry: PSDI means presence-sensing device initiation.
3.4.2
operating mode selection device
facility consisting of an access, selection and activation system for manual selection of the machine’s
operating mode (3.4.1), to which only a restricted group of persons has access
Note 1 to entry: See 5.4.3.
3.4.3
function
operation of a machine or a part of a machine which is specific or required for the intended machine task
3.4.4
cycle
complete movement of the slide and other devices of the press (3.1.1) used for production (e.g. cushions,
workpiece ejectors) including feeding and removal of the material or workpiece:
— for hydraulic or pneumatic presses or mechanical servo presses, along a programmed motion path
from the initial start position back to the same position, or
— for mechanical presses with clutch, from the cycle start position [normally top dead centre (3.2.4)]
through to bottom dead centre (3.2.4) back to the cycle stop position
4 List of significant hazards
This clause contains all significant hazards, hazardous situations and events as far as they are dealt
with in this document, 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 Table A.1.
Particular attention is given to hazards dealing with the following:
— crushing and shearing between moving parts such as tools, slide, ejectors, components mounted in
the die to perform specific functions (see Table A.1);
— entanglement on or drawing into moving parts of the machine, guards, motor and drive machinery,
mechanical handling device (see Table A.1);
— ejection of machine components (see Table A.1).
Main danger zones are the following:
— tools area with moving parts;
— mechanical handling device.

5 Safety requirements and/or measures
5.1 General
The methods or measures to be implemented to eliminate the significant hazards or reduce their
associated risks are detailed in this clause in the following manner:
— basic design considerations for major press components or systems (see 5.2);
— safeguarding against mechanical hazards in the tools area under different modes of production
(see 5.3);
— protection against hazards due to control system or control component failures (see 5.4);
— safeguarding against hazards which can occur during tool-setting, trial strokes, maintenance and
lubrication (see 5.5);
— safeguarding against other hazards (see 5.6 to 5.8).
5.2 Basic design considerations
5.2.1 Hydraulic and pneumatic systems — Common features
5.2.1.1 The general requirements in ISO 4413 and ISO 4414 shall be taken into consideration in
designing hydraulic and pneumatic systems, which shall comply with the particular requirements in
5.2.2 and 5.2.3.
5.2.1.2 Filters, pressure regulators, and low pressure cut-off arrangements shall be provided.
5.2.1.3 Pressure control devices shall be provided to ensure that the permitted range of working
pressure is maintained.
5.2.1.4 Pressurized transparent bowls (e.g. glass, plastic) shall be protected to prevent injury from
projection of fragments, without affecting visibility.
5.2.1.5 All piping, pipe fittings, passages, surge or storage tanks and cored or drilled holes shall be free
from burrs or foreign matter which might cause damage to the system. See ISO 4413:2010, 5.4.6.4 and
ISO 4414:2010, 5.4.5.4.
5.2.1.6 Each run of piping shall, where practicable, be continuous from one piece of apparatus to
another.
Precautions shall be taken to prevent damage by thermal expansion. Rigid piping shall be securely
supported at frequent intervals to avoid vibration or movement. Care shall be taken to avoid kinking
of flexible pipes and hoses used to carry fluids. Such kinking can cause traps which prevent the fluid
exhausting.
5.2.1.7 Where a drop in pressure could lead to unintended dangerous motion of the slide/ram, flexible
piping shall not be used. Pipes and pipe connections shall be chosen to prevent such a loss of pressure.
Such pipe connections shall not be made with compression fittings, glued rings or similar devices. They
shall be made by means of positive connecting joints, or by the welding of two fitted surfaces.
5.2.1.8 Operating valves shall not depend on connected piping for support, e.g. be fitted to a mounting
plate or to the cylinder. This is to avoid undesirable effects from vibration which might affect both valves
and piping.
