Safety of machinery - Prevention of unexpected start-up (ISO 14118:2017)
ISO 14118:2017 specifies requirements for designed-in means aimed at preventing unexpected machine start-up (see 3.2) to allow safe human interventions in danger zones (see Annex A).
ISO 14118:2017 applies to unexpected start-up from all types of energy source, i.e.:
- power supply, e.g. electrical, hydraulic, pneumatic;
- stored energy due to, e.g. gravity, compressed springs;
- external influences, e.g. from wind.
ISO 14118:2017 does not specify performance levels or safety integrity levels for safety-related parts of control systems. While available means to prevent unexpected start-up are identified, this document does not specify the means for the prevention of unexpected machine start-up for specific machines.
NOTE A type-C standard can define the required means for the prevention of harm arising from unexpected start-up. Otherwise, the requirements for a specific machine need to be determined by risk assessment outside the scope of this document.
Sicherheit von Maschinen - Vermeidung von unerwartetem Anlauf (ISO 14118:2017)
Dieses Dokument legt konstruktive Maßnahmen fest, die darauf gerichtet sind, unerwarteten Anlauf (siehe 3.2) zu vermeiden, um sicheren Eingriff von Personen in Gefahrbereiche (siehe Anhang A) zu ermöglichen.
Dieses Dokument bezieht sich auf unerwarteten Anlauf durch alle Arten von Energie, d. h.:
— Energieversorgung, z. B. elektrisch, hydraulisch, pneumatisch;
— gespeicherte Energie, z. B. durch Schwerkraft, gespannte Federn;
— äußere Einflüsse, z. B. durch Wind.
In diesem Dokument werden keine Performance Level oder Sicherheits-Integritätslevel für sicherheitsrelevante Teile von Steuerungssystemen festgelegt. Obwohl Maßnahmen zur Vermeidung von unerwartetem Anlauf bekannt sind, werden in diesem Dokument nicht die Maßnahmen zur Vermeidung eines unerwarteten Anlaufs für bestimmte Maschinen festgelegt.
ANMERKUNG Eine Typ-C-Norm kann die erforderlichen Maßnahmen zur Verhinderung von Schäden aufgrund eines unerwarteten Anlaufs definieren. Andernfalls müssen die Anforderungen für eine bestimmte Maschine durch eine Risikobewertung außerhalb des Geltungsbereichs dieses Dokuments festgelegt werden.
Sécurité des machines - Prévention de la mise en marche intempestive (ISO 14118:2017)
ISO 14118:2017 spécifie des exigences pour les mesures de sécurité intégrée destinées à empêcher la mise en marche intempestive d'une machine (voir 3.2), afin de permettre des interventions humaines en toute sécurité dans des zones dangereuses (voir l'Annexe A).
ISO 14118:2017 s'applique à la mise en marche intempestive depuis tous les types de source d'énergie, c'est-à-dire:
- alimentation en énergie, par exemple électrique, hydraulique, pneumatique;
- énergie emmagasinée en raison, par exemple, de la pesanteur, de ressorts comprimés;
- influences externes, par exemple effets du vent.
ISO 14118:2017 ne spécifie pas de niveaux de performance ou d'intégrité de sécurité pour les parties de systèmes de commande relatives à la sécurité. Même si le présent document identifie les moyens disponibles pour la prévention de la mise en marche intempestive, il ne spécifie pas les moyens de préventions de mise en marche intempestive pour des machines spécifiques.
NOTE Une norme de type C peut définir les moyens exigés pour la prévention de dommage lié à la mise en marche intempestive. Dans le cas contraire, il convient de déterminer les exigences d'une machine spécifique par une appréciation du risque n'étant pas inclue dans le domaine d'application du présent document.
Varnost strojev - Preprečevanje nepričakovanega zagona (ISO 14118:2017)
Ta evropski standard določa projektirana sredstva, ki so predvidena za preprečevanje nepričakovanega zagona stroja zaradi omogočanja varnih intervencij ljudi na nevarnih območjih. Uporablja se za nepričakovane zagone na podlagi vseh vrst virov energije, tj. napajanja, npr. električne, hidravlične, pnevmatske, shranjene energije zaradi npr. gravitacije, stisnjenih vzmeti in zunanjih vplivov, npr. vetra.

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.
The procedures used to develop this document and those intended for its further maintenance are
described in the ISO/IEC Directives, Part 1. In particula
