EN ISO 14120:2015

Safety of machinery - Guards - General requirements for the design and construction of fixed and movable guards (ISO 14120:2015)

ISO 14120:2015 specifies general requirements for the design, construction, and selection of guards provided to protect persons from mechanical hazards.
ISO 14120:2015 indicates other hazards that can influence the design and construction of guards.
ISO 14120:2015 applies to guards for machinery which will be manufactured after it is published.
The requirements are applicable if fixed and movable guards are used. This International Standard does not cover interlocking devices. These are covered in ISO 14119.
ISO 14120:2015 does not provide requirements for special systems relating specifically to mobility such as ROPS (rollover protective structures), FOPS (falling-object protective structures), and TOPS (tip over protective structures) or to the ability of machinery to lift loads.

Sicherheit von Maschinen - Trennende Schutzeinrichtungen - Allgemeine Anforderungen an Gestaltung und Bau von feststehenden und beweglichen trennenden Schutzeinrichtungen (ISO 14120:2015)

Diese Internationale Norm legt allgemeine Anforderungen an die Gestaltung, den Bau und die Auswahl von trennenden Schutzeinrichtungen fest, die dem Schutz von Personen vor mechanischen Gefährdungen dienen.
Diese Internationale Norm gibt weitere Gefährdungen an, die die Gestaltung und den Bau von trennenden Schutzeinrichtungen beeinflussen können.
Diese Internationale Norm gilt vorrangig für trennende Schutzeinrichtungen an Maschinen, die nach der Veröffentlichung dieser Norm gebaut werden.
Die Anforderungen gelten für den Einsatz von feststehenden und beweglichen trennenden Schutz¬einrichtungen. Diese Internationale Norm behandelt keine Verriegelungseinrichtungen. Diese werden in ISO 14119 behandelt.
Diese Internationale Norm enthält keine Anforderungen an besondere Schutzsysteme, die besonders für die Mobilität wie ROPS (Überrollschutzaufbau, en: rollover protective structures), FOPS (Schutzaufbau gegen herabfallende Gegenstände, en: falling-object protective structures) und TOPS (Umsturzvorrichtung, en: tip over protection structures) oder die Fähigkeit zum Heben von Lasten vorgesehen sind.

Sécurité des machines - Protecteurs - Prescriptions générales pour la conception et la construction des protecteurs fixes et mobiles (ISO 14120:2015)

ISO 14120:2015 spécifie les prescriptions générales pour la conception, la construction, et le choix des protecteurs destinés à la protection des personnes contre les phénomènes dangereux mécaniques.
ISO 14120:2015 indique d'autres phénomènes dangereux susceptibles d'influer sur la conception et la construction des protecteurs.
ISO 14120:2015 s'applique aux protecteurs de machines qui seront fabriquées après sa publication.
Les prescriptions sont applicables lorsque des protecteurs fixes et mobiles sont utilisés. La présente Norme internationale ne traite pas des dispositifs de verrouillage. Ceux-ci sont traités par l'ISO 14119.
ISO 14120:2015 ne donne pas de prescriptions pour les systèmes de protection spécifiques à la mobilité tels que ROPS (structures de protection au retournement), FOPS (structures de protection contre les chutes d'objets), et TOPS (structures de protection au basculement) ou à la capacité des machines à lever des charges.

Varnost strojev - Varovala - Splošne zahteve za načrtovanje in konstruiranje nepomičnih in pomičnih varoval (ISO 14120:2015)

Ta dokument določa splošne zahteve za načrtovanje in konstruiranje varoval, namenjenih predvsem zaščiti oseb pred mehanskimi tveganji. Ta standard velja predvsem za stroje, ki so bili izdelani po datumu objave tega standarda. Izpostavljena je uporaba varoval za zmanjšanje izpostavljenosti nemehanskim tveganjem. Zahteve veljajo za uporabo nepomičnih in pomičnih varoval. Standard ne zajema delov varoval, ki sprožijo zaporne naprave. Te so zajete v standardu EN 1088 (ISO 14119). Ta dokument ne podaja zahtev za posebne sisteme, ki se nanašajo zlasti na mobilnost in zmožnost dviganja bremen, kot so zaščitne strukture proti prevrnitvi (ROPS) in zaščitne strukture proti padajočim objektom (FOPS).
