Safety of machinery - Risk assessment - Part 1: Principles (ISO 14121-1:2007)
ISO 14121-1:2007 establishes general principles intended to be used to meet the risk reduction objectives established in ISO 12100-1:2003, Clause 5. These principles of risk assessment bring together knowledge and experience of the design, use, incidents, accidents and harm related to machinery in order to assess the risks posed during the relevant phases of the life cycle of a machine.
ISO 14121-1:2007 provides guidance on the information that will be required to enable risk assessment to be carried out. Procedures are described for identifying hazards and estimating and evaluating risk. It also gives guidance on the making of decisions relating to the safety of machinery and on the type of documentation required to verify the risk assessment carried out.
It is not applicable to risks posed to domestic animals, property or the environment.
Sicherheit von Maschinen - Risikobeurteilung - Teil 1: Leitsätze (ISO 14121-1:2007)
Dieser Teil von ISO 14121 stellt allgemeine Leitsätze auf, die genutzt werden können, um die in ISO 12100 1:2003, Abschnitt 5, festgelegten Ziele zur Risikominderung zu erreichen. Diese Leitsätze zur Risikobeurteilung tragen Kenntnisse und Erfahrungen über die Konstruktion, den Einsatz, das Zwischenfall- und Unfallgeschehen sowie über Schäden im Zusammenhang mit Maschinen zusammen, um in den relevanten Phasen der Lebensdauer einer Maschine dargestellte Risiken beurteilen zu können.
Dieser Teil von ISO 14121 gibt eine Anleitung über die Informationen, die für die Durchführung einer Risikobeurteilung notwendig sind. Es werden Verfahren zur Identifizierung von Gefährdungen sowie zur Risikoeinschätzung und bewertung beschrieben.
Dieser Teil von ISO 14121 stellt außerdem eine Handlungshilfe für Entscheidungen bereit, die im Zusammenhang mit der Sicherheit von Maschinen zu treffen sind, sowie zur Art der Dokumentation, anhand derer die vorgenommene Risikobeurteilung nachzuweisen ist.
Dieser Teil von ISO 14121 ist nicht anwendbar auf Risiken in Bezug auf Haustiere, Eigentum oder die Umwelt.
Sécurité des machines - Appréciation du risque - Partie 1: Principes (ISO 14121-1:2007)
L'ISO 14121-1:2007 établit les principes généraux utiles pour atteindre les objectifs de réduction du risque spécifiés dans l'ISO 12100-1:2003, Article 5. Ces principes généraux sont dénommés appréciation du risque par laquelle la connaissance et l'expérience de la conception, de l'utilisation, des incidents, des accidents et des dommages liés à la machine sont rassemblées dans le but d'apprécier les risques au cours de toutes les phases de la vie de la machine.
L'ISO 14121-1:2007 donne des indications sur l'information nécessaire pour permettre d'effectuer l'appréciation du risque. Elle décrit des procédures d'identification des phénomènes dangereux et d'estimation et d'évaluation des risques. Elle donne également des conseils sur les décisions à prendre en matière de sécurité des machines et sur le type de documentation nécessaire pour vérifier l'appréciation du risque qui a été menée.
Elle ne traite pas des risques de préjudices causés aux animaux, aux biens ou à l'environnement.

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 14121-1 was prepared by Technical Committee ISO/TC 199, Safety of machinery.
This first edition of ISO 14121-1 cancels and replaces ISO 14121:1999, of which it constitutes a technical
revision.
ISO 14121 consists of the following parts, under the general title Safety of machinery — Risk assessment:
⎯ Part 1: Principles
⎯ Part 2: Practical guidance and examples of methods [Technical Report]

Introduction
The structure of safety standards in the field of machinery is as follows.
a) Type-A standards (basic standards) give basic concepts, principles for design, and general aspects that
can be applied to machinery.
b) Type-B standards (generic safety standards) deal with one or more safety aspect(s) or one or more
type(s) of safeguards that can be used across a wide range of machinery:
⎯ type-B1 standards on particular safety aspects (e.g. safety distances, surface temperature, noise);
⎯ type-B2 standards on safeguards (e.g. two-hands controls, interlocking devices, pressure sensitive
devices, guards).
c) Type-C standards (machine safety standards) deal with detailed safety requirements for a particular
machine or group of m
