Machine tools safety - Presses - Part 2: Safety requirement for mechanical presses
1.1 This European Standard specifies technical safety requirements and measures to be adopted by persons undertaking the design, manufacture and supply of mechanical presses with part revolution clutch hereinafter called presses which are intended to work cold metal or material partly of cold metal.
NOTE The design of a machine includes the study of the machine itself, taking into account all phases of its “life”, i.e. construction, transport and commission (including assembly, installation and adjustment), use (including setting, teaching/programming or process changeover, operation, cleaning, fault finding and maintenance) and de-commissioning, dismantling and, as far as safety is concerned, disposal, and the drafting of the instructions related to all above-mentioned phases of the “life” of the machine (except construction), dealt with it in 6.5 of EN ISO 12100-2:2003.
1.2 This European Standard also covers presses, whose primary intended use is to work cold metal, which are to be used in the same way to work other sheet materials (such as cardboard, plastic, rubber or leather), and metal powder.
1.3 The requirements in this standard take account of intended use, as defined in 3.22 of EN ISO 12100-1:2003. This standard presumes access to the press from all directions, deals with the 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.
1.4 This European Standard also applies to ancillary devices which are an integral part of the press. This standard also applies to machines which are integrated into an automatic production line where the hazards and risk arising are comparable to those of machines working separately.
1.5 This European Standard does not cover mechanical presses with full revolution clutch.
1.6 This European Standard does not cover machines whose principal designed purpose is:
a) sheet metal cutting by guillotine;
b) attaching a
Werkzeugmaschinen Sicherheit - Pressen - Teil 2: Mechanische Pressen
Dieses Dokument legt, zusätzlich zu ISO 16092-1, die technischen Sicherheitsanforderungen und maßnahmen fest, die von Personen zu beachten sind, die mit der Konstruktion, der Herstellung und der Lieferung der folgenden Bauarten von hydraulischen Pressen und den folgenden mechanischen Pressenproduktionssystemen betraut sind.
- Bauart 1: Pressen mit kraftschlüssiger(n) Kupplung(en);
- Bauart 2: Pressen mit einem Servo-Antriebssystem. (Mechanische Servopressen).
ANMERKUNG 1 Die Anforderungen in diesem Dokument gelten im Wesentlichen für beide Bauarten der mechanischen Presse. Gilt eine Anforderung nur für eine Bauart, wird die Bauart spezifiziert.
ANMERKUNG 2 Andere Arten von motorisierten Antriebssystemen bieten ähnliche Funktionalitäten wie das, was allgemein als "Servoantriebe" oder "Servomotoren" bezeichnet wird, und als solche wird ihre Verwendung innerhalb der in diesem Dokument verwendeten Begriffe als gleich betrachtet (z. B. variable Frequenzantriebssysteme).
Die durch dieses Dokument abgedeckten Pressen variieren im Größenbereich von kleinen Hochgeschwindigkeitsmaschinen mit einem einzelnen Bediener, welche kleine Werkstücke produzieren bis hin zu großen Maschinen mit relativ langsamer Geschwindigkeit mit mehreren Bedienern und großen komplexen Werkstücken.
Dieses Dokument befasst sich mit allen für mechanische Pressen relevanten signifikanten Gefährdungen und mit Zusatzeinrichtungen (zum Beispiel das Bewegen von Ziehkissen, Werkstückauswürfe, Zuführungs- und Transfersysteme), die ein fester Bestandteil der Maschine sind, und zwar bei bestimmungsgemäßer Verwendung und unter den Bedingungen von missbräuchlicher Verwendung, welche vom Hersteller vernünftigerweise vorhersehbar sind (siehe Abschnitt 4). Alle Phasen der Lebensdauer der Maschine, wie in ISO 12100:2010, 5.4 beschrieben, haben Berücksichtigung gefunden.
ANMERKUNG 2 Alle wesentlichen Gefährdungen sind solche, die zum Zeitpunkt der Veröffentlichung dieses Dokuments identifiziert wurden oder mit Pressen verbunden sind.
Zusätzlich zu den Maschinen, die nicht von ISO 16092-1:2017 abgedeckt werden, deckt dieses Dokument keine Maschinen ab, die:
a) Energie für die Bewegung des Pressenstößels hydraulisch oder pneumatisch übertragen;
b) über zwei oder mehr Stößel verfügen, die sich in unterschiedlichen Winkelausrichtungen zueinander bewegen;
ANMERKUNG 3 Dieses Dokument gilt für Pressen, die über zwei oder mehr Stößel verfügen, die sich in denselben Winkelausrichtungen bewegen, zum Beispiel eine Presse, die über innere und äußere Stößel verfügt.
c) Energie übertragen, um die Bewegung des Pressenstößels mit Hilfe eines Linearmotor-Mechanismus zu übertragen.
Sécurité des machines-outils - Presses - Partie 2 : Exigences de sécurité pour les presses mécaniques
Le présent document, appliqué avec l'ISO 16092‑1, spécifie les exigences techniques de sécurité et les dispositions que doivent respecter les personnes chargées de la conception, de la construction et de la fourniture des groupes suivants de presses mécaniques et de systèmes de production des presses mécaniques:
— Groupe 1: Presses à embrayage à friction;
— Groupe 2: Presses avec un système de servo-entraînement (servopresses mécaniques).
NOTE 1 Les exigences du présent document s'appliquent essentiellement à ces deux groupes de presse mécanique. Lorsqu'une exigence ne s'applique qu'à un seul groupe, celui-ci est alors spécifié.
NOTE 2 D'autres types de systèmes d'entraînement motorisés offrent des fonctionnalités similaires à ce que l'on appelle communément les «systèmes de servo-entraînement» ou «servomoteurs», et leur utilisation est donc considérée comme identique dans les termes utilisés dans le présent document (par exemple, les systèmes d'entraînement à fréquence variable).
Les presses couvertes par le présent document vont des petites machines à grande vitesse avec un seul opérateur produisant de petites pièces aux grandes machines à vitesse relativement lente avec plusieurs opérateurs et produisant de grandes pièces complexes.
Le présent document traite de tous les phénomènes dangereux significatifs applicables aux presses mécaniques et dispositifs auxiliaires (par exemple: les coussins mobiles, les éjecteurs de pièces et les systèmes d'alimentation et de transfert) qui font partie intégrante de la machine, lorsqu'elles sont utilisées normalement et dans les conditions de mauvais usage raisonnablement prévisible par le fabricant (voir l'Article 4). Toutes les phases du cycle de vie de la machine, telles que décrites dans l'ISO 12100:2010, 5.4 ont été prises en compte.
NOTE 2 L'expression «tous les phénomènes dangereux significatifs» fait référence à ceux qui sont identifiés ou associés aux presses au moment de la publication du présent document.
Outre les machines non couvertes par l'ISO 16092‑1:2017, le présent document ne couvre pas les machines qui:
a) transmettent de l'énergie pour donner un mouvement du coulisseau de la presse en utilisant des moyens hydrauliques ou pneumatiques;
b) ont deux ou plusieurs coulisseaux mobiles dans différentes positions angulaires les uns par rapport aux autres;
NOTE 3 Le présent document s'applique aux presses qui ont deux ou plusieurs coulisseaux mobiles dans le même positionnement angulaire, par exemple, une presse qui a des coulisseaux intérieurs et extérieurs.
c) transmettent de l'énergie pour donner un mouvement du coulisseau de la presse en utilisant un ou des mécanisme(s) de moteur linéaire(s).

Machine tools safety — Presses —
Part 2:
Safety requirement for mechanical presses
1 Scope
This document, in addition to ISO 16092-1, specifies technical safety requirements and measures to
be adopted by persons undertaking the design, manufacture and supply of the following groups of
mechanical presses and mechanical press production systems:
— Group 1: Presses with a part revolution clutch(es);
— Group 2: Presses with a servo drive system (Mechanical servo presses).
NOTE 1 Requirements in this document are essentially applicable to both groups of the mechanical press. If a
requirement applies to only one group, then the group is specified.
NOTE 2 Other types of motorized drive systems provide similar functionalities to what is commonly called
“servo drives” or "servo motors”, and as such their use is considered the same within the terms used in this
document (e.g. variable frequency drive systems).
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 to mechanical presses and ancillary devices
(e.g. moving die cushions, work-piece ejectors, feeding and transfer systems) which are integral to the
machine, when they are used as intended and under the conditions of misuse which are reasonably
foreseeable by the manufacturer (see Clause 4). All phases of the machine life cycle as described in
ISO 12100:2010, 5.4 have been taken into consideration.
NOTE 2 All significant hazards means those identified or associated with presses at the time of the publication
of this document.
In addition to machines not covered by ISO 16092-1:2017, this document does not cover machines which:
a) transmit energy to impart press slide motion by using hydraulic or pneumatic means;
b) have two or more slides moving in different angular orientations from each other;
NOTE 3 This document applies to presses which have two or more slides moving in the same angular
orientations, e.g. a press which has inner and outer slides.
c) transmit energy to impart press slide motion by using a linear motor mechanism(s).

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

Introduction
This document is a “type C” standard as stated in ISO12100.
It 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 by the above-mentioned stakeholder
groups by means of this document:
— 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 in the drafting
process of this document.
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
standard.
This document is intended to be applied in addition to ISO 16092-1.

DRAFT INTERNATIONAL STANDARD ISO/DIS 16092-2:2018(E)
Machine tools safety — Presses — Part 2: Safety requirements
for mechanical presses
1 Scope
This document, in addition to ISO 16092-1, specifies technical safety requirements and measures to be
adopted by persons undertaking the design, manufacture and supply of the following groups of
mechanical presses and mechanical press production systems.
Group 1: Presses with a part revolution clutch(es).
Group 2: Presses with a servo drive system. (Mechanical servo presses)
NOTE 1 Requirements in this document are essentially applicable to both groups of the mechanical press. If a
requirement applies to only one group then the group is specified.
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 to mechanical presses and ancillary devices (for
example, moving die cushions, work-piece ejectors, feeding and transfer systems) which are integral to
the machine, when they are used as intended and under the conditions of misuse which are reasonably
foreseeable by the manufacturer (see Clause 4). All phases of the machine life cycle as described in ISO
12100:2010, 5.4 have been taken into consideration.
NOTE 2 All significant hazards means those identified or associated with presses at the time of the publication of
this document.
This document does not cover machines whose principal designed purpose is described in ISO 16092-
1:2017, 1 and machines which
a) transmit energy to impart press motion by using hydraulic or pneumatic means;
b) have two or more slides moving in different angular orientations from each other;
NOTE 3 This document applies to presses which have two or more slides moving in the same angular orientations,
for example, a press which has inner and outer slides.
c) utilize a linear motor mechanism(s).
