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.
International Standards are drafted in accordance with the rules given in the ISO/IEC Directives, Part 2.
The main task of technical committees is to prepare International Standards. Draft International Standards
adopted by the technical committees are circulated to the member bodies for voting. Publication as an
International Standard requires approval by at least 75 % of the member bodies casting a vote.
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.
ISO 4414 was prepared by Technical Committee ISO/TC 131, Fluid power systems, Subcommittee SC 9,
Installations and systems.
This third edition cancels and replaces the second edition (ISO 4414:1998), which has been technically
revised, specifically with regards to the following:
a) integration of ISO 4414:1998 and EN 983:1996;
b) integration of safety requirements to comply with the European Machinery Directive 2006/42/EC;
c) updating of safety requirements, taking into account International Standards on machine safety.

Introduction
This International Standard is a type B standard as defined in ISO 12100. The stipulations of this International
Standard can be supplemented or modified by a type C standard. For machines that are covered by the scope
of a type C standard and that have been designed and built in accordance with the provisions of that standard,
the provisions of that type C standard take precedence over the provisions of this type B standard.
In pneumatic fluid power systems, power is transmitted and controlled through air or a neutral gas under
pressure within a circuit.
The application of pneumatic fluid power systems requires a thorough understanding and precise
communication between the supplier and purchaser. This International Standard was prepared to assist that
understanding and communication and to document many of the good practices learned from experience with
pneumatic systems.
Use of this International Standard assists in
a) identifying and specifying the requirements for pneumatic systems and components;
b) identifying respective areas of responsibility;
c) designing systems and their components to comply with specific requirements;
d) understanding the safety requirements of a pneumatic system.
Equivalent requirements for hydraulic systems are defined in ISO 4413.

5 General rules and safety requirements
5.1 General
5.1.1 When designing pneumatic systems for machinery, all intended operations and use of systems shall
be considered. Risk assessment, e.g. in accordance with ISO 14121-1, shall be carried out to determine the
foreseeable risks associated with systems when they are used as intended. Reasonably foreseeable misuse
shall not cause hazards. The risks identified shall be eliminated by design and, where this is not practicable,
safeguards (first preference) or warnings (second preference) against such risks shall be incorporated, in
accordance with the hierarchy established in ISO 12100.
NOTE This International Standard provides requirements for components of fluid power systems; some of these
requirements are dependent on the hazards associated with the machine in which the system is installed. Therefore, the
final specification and construction of the pneumatic system could need to be based on risk assessment and agreement
between purchaser and supplier.
5.1.2 The control systems shall be designed in accordance with the risk assessment. This requirement is
met when ISO 13849-1 is used.
5.1.3 The prevention of damage to the machine, systems and the environment shall be considered.
5.1.4 Deviations from this International Standard shall be agreed to in writing between the purchaser and
supplier. Attention should be drawn by the purchaser and/or the supplier to applicable national and local
codes or laws.
5.2 Basic requirements for the design and specification of pneumatic systems
5.2.1 Component selection
5.2.1.1 All components and piping in the system shall be selected or specified to provide for safety in use,
and they shall operate within their rated limits when the system is put to its intended use. Components and
piping shall be selected or specified so as to ensure that they can operate reliably under all intended uses of
the system. Particular attention shall be paid to the reliability of components and piping that can create a
hazard in the event of their failure or malfunction.
5.2.1.2 Components and piping shall be selected, applied and installed in accordance with the
manufacturer's recommendations.
5.2.1.3 It is recommended that wherever practicable, components and piping made in accordance with
recognized International Standards should be used.
5.2.2 Unintended pressures
5.2.2.1 All related parts of the system shall be designed or otherwise protected against foreseeable
pressures exceeding the maximum working pressure of the system or the rated pressure of any part of the
system if the excessive pressure can cause a hazard.
5.2.2.2 The preferred means of protection against excessive pressure is one or more pressure-relief
valves located to limit the pressure in all related parts of the system. Other means, such as pressure
regulators, may be used, provided these means satisfy the application requirements.
5.2.2.3 Systems shall be designed, constructed and adjusted to minimize pressure surges and
fluctuations. Pressure surges and fluctuations shall not cause hazards.
5.2.2.4 Loss of pressure or pressure drop shall not expose persons to a hazard and should not damage
the machinery.

SIST EN ISO 4414:2011
ISO 4414:2010(E)
5.2.2.5 All pneumatic components shall vent into a non-hazardous area with a connection to the
atmosphere.
5.2.2.6 Means shall be provided to prevent unacceptable pressure build-up where high external loads are
reflected on actuators.
5.2.3 Mechanical movements
Mechanical movements, whether intended or unintended (e.g. effects from acceleration, deceleration or
lifting/holding of masses), shall not result in a situation hazardous to persons.
5.2.4 Noise
In the design of pneumatic systems, the expected noise shall be taken into account. Depending on the
application, measures shall be taken to minimize the risks caused by noise. Airborne noise and structure-
borne noise shall be considered.
NOTE For the design of low-noise machinery and systems, see ISO/TR 11688-1.
5.2.5 Leakage
Leakage (internal or external) shall not cause hazards.
5.2.6 Operational and functional requirements for pneumatic systems
The following specifications for operation and function shall be defined:
a) working pressure range;
b) working temperature range;
c) type of gas to be used (e.g., air, nitrogen or other neutral gas);
d) cycle rates;
e) duty cycle;
f) service life of components;
g) sequence of events;
h) filtration and lubrication, including identification of components not to be lubricated;
i) lifting provisions;
j) emergency, safety and energy isolation requirements;
k) painting or protective coating;
l) lubricant compatibility with components.
Annex B provides forms and checklists to facilitate the gathering and recording of this information. These
forms and checklists can also be useful to record those specifications that apply to pneumatic systems used in
mobile machinery. The individual forms in Annex B are also available in a separate revisable electronic format.

ISO 4414:2010(E)
5.2.7 Control or energy supply
Whatever the type of control or energy supply used (e.g., electrical, pneumatic), the following actions or
occurrences (whether unexpected or intentional) shall not create a hazard:
a) switching the supply on or off;
b) reducing the supply;
c) cutting off the supply;
d) restoring the supply (unexpectedly or intentionally).
5.2.8 Positive isolation from energy sources
The system shall be designed to facilitate positive isolation from energy sources (see ISO 12100:2010,
6.3.5.4). In pneumatic systems, this can be done, for example, by
⎯ isolating the supply with a suitable shut-off device, which should be lockable, and shall be accessible
without causing a hazard, or isolating and dissipating pressure from the system with a suitable shut-off
device(s) having a pressure-release feature, which can need to be lockable;
⎯ releasing or supporting mechanical loads when the system is depressurized;
⎯ isolating the electrical supply (see IEC 60204-1:2009, 5.3).
The system shall facilitate dissipation of the fluid pressure.
Precautions should be taken when the supply is reinstated after isolation or depressurization.
5.2.9 Location of components and controls
The system shall be designed and constructed so that components and controls are located where they are
easily accessible for use, adjustment and maintenance without causing hazard.
5.2.10 Unexpected start-up
In order to prevent unexpected start-up, precautions shall be taken in accordance with ISO 14118.
5.2.11 Uncontrolled actuator movement
If rapid opening of the shut-off valve can produce uncontrolled movement of actuators, a soft-start/slow-start
valve shall be incorporated.
5.2.12 Airborne hazardous substances
Systems shall be so designed, constructed and/or equipped that airborne hazardous substances are
minimized.
