Safety of machinery - Prevention of unexpected start-up

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.

Safety of machinery - Prevention of unexpected start-up

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.

Safety of machinery - Prevention of unexpected start-up

Le présent document fait partie d'une série de normes "horizontales" de type B1 (traitant d'un aspect de sécurité pour une large gamme de machines). Il donne des éléments aux concepteurs de machines, aux rédacteurs de normes de type C, etc., pour assurer une présomption de conformité par rapport aux exigences essentielles relatives à la consignation des Directives "Machine" 98/37/CE et 2006/42/CE. Il complète la norme NF EN ISO 13850 traitant de l'arrêt d'urgence.
