Safety of machinery - Two-hand control devices - Principles for design and selection (ISO 13851:2019)
This document specifies the safety requirements of a two-hand control device (THCD) and the dependency of the output signal from the actuation by hand of the control actuating devices.
This document describes the main characteristics of THCDs for the achievement of safety and sets out combinations of functional characteristics for three types. It does not apply to devices intended to be used as enabling devices, as hold-to-run devices or as special control devices.
This document does not specify with which machines THCDs shall be used. It also does not specify which types of two-hand-control device shall be used for a specific application. Moreover, while guidance is given, it does not specify the required distance between the THCD and the danger zone (see 8.8).
This document provides requirements for design and guidance on the selection (based on a risk assessment) of THCDs including the prevention of defeat, the avoidance of faults and verification of compliance.
NOTE 1 A THCD only offers protection for the person using it.
NOTE 2 For specific machines, the suitability of a two-hand control as a suitable protective device can be defined in a type-C standard. If such a standard does not exist or is not appropriate, the risk assessment and determination of suitable protective measures is the responsibility of the manufacturer of the machine.
This document applies to all THCDs, independent of the energy used, including:
— THCDs which are fully assembled for installation;
— THCDs which are assembled by the machine manufacturer or integrator.
This document is not applicable to THCDs manufactured before the date of its publication.
Sicherheit von Maschinen - Zweihandschaltungen - Funktionelle Aspekte und Gestaltungsleitsätze (ISO 13851:2019)
Dieses Dokument legt die Sicherheitsanforderungen an eine Zweihandschaltung und die Abhängigkeit des Ausgangssignals von der manuellen Betätigung der Stellteile fest.
Dieses Dokument beschreibt die Haupteigenschaften von Zweihandschaltungen zur Erlangung von Sicherheit und führt Kombinationen von funktionalen Eigenschaften für 3 Typen auf. Dieses Dokument gilt nicht für Einrichtungen, die für die Verwendung als Zustimmungseinrichtung, Steuerungseinrichtung mit selbsttätiger Rückstellung (Tippschalter) oder als spezielle Steuereinrichtung bestimmt sind.
Dieses Dokument legt nicht fest, mit welchen Maschinen Zweihandschaltungen angewendet werden müssen. Es legt ebenfalls nicht fest, welche Typen von Zweihandschaltungen für eine bestimmte Anwendung verwendet werden müssen. Darüber hinaus legt es nicht den erforderlichen Abstand zwischen der Zweihandschaltung und dem Gefahrbereich fest (siehe 8.8), auch wenn hierzu Anleitungen gegeben werden.
Dieses Dokument stellt Anforderungen an die Gestaltung und Anleitungen zur Auswahl (als Ergebnis einer Risikobeurteilung) von Zweihandschaltungen einschließlich der Verhinderung des Umgehens, des Vermeidens von Ausfällen und der Konformitätsüberprüfung zur Verfügung.
ANMERKUNG 1 Eine Zweihandschaltung bietet nur der Person Schutz, die sie verwendet.
ANMERKUNG 2 Für spezifische Maschinen kann die Eignung einer Zweihandschaltung als geeignete Schutzeinrichtung in einer Typ-C-Norm festgelegt werden. Falls eine solche Norm nicht existiert oder nicht zutrifft, liegt die Risikobeurteilung und die Bestimmung geeigneter Schutzmaßnahmen in der Verantwortung des Maschinenherstellers.
Dieses Dokument gilt für alle Zweihandschaltungen, unabhängig von der verwendeten Energie, einschließlich:
Zweihandschaltungen, die für die Montage komplett zusammengebaut vorliegen;
Zweihandschaltungen, die vom Maschinenhersteller oder -integrierer zusammengebaut werden.
Dieses Dokument gilt nicht für Zweihandschaltungen, die vor dem Veröffentlichungsdatum dieses Dokuments hergestellt wurden.
Sécurité des machines - Dispositifs de commande bimanuelle - Principes de conception et de choix (ISO 13851:2019)
Le présent document spécifie les spécifications de sécurité d'un dispositif de commande bimanuelle et l'interdépendance du signal de sortie et de l'actionnement manuel des organes de service.
Le présent document décrit les principales caractéristiques des dispositifs de commande bimanuelle permettant d'assurer la sécurité, et établit des combinaisons de caractéristiques fonctionnelles pour trois types. Il ne s'applique pas aux dispositifs destinés à être utilisés comme dispositifs de validation, comme dispositifs de commande nécessitant une action maintenue, ou comme dispositifs de commande spéciaux.
Le présent document ne spécifie pas avec quelles machines les dispositifs de commande bimanuelle doivent être utilisés. Il ne spécifie pas non plus quels types de dispositifs de commande bimanuelle doivent être utilisés pour une application spécifique. Enfin, il ne spécifie pas la distance entre le dispositif de commande bimanuelle et la zone dangereuse (voir 8.8).
Le présent document fournit des exigences sur la conception et des conseils sur le choix (basés sur l'appréciation du risque) de dispositifs de commande bimanuelle y compris la vérification de conformité, et la prévention de la fraude et des défauts.
NOTE 1 Un dispositif de commande bimanuelle n'offre de protection qu'à son utilisateur.
NOTE 2 La pertinence de l'utilisation d'un dispositif de commande bimanuelle comme dispositif de protection pour les machines spécifiques peut être définie dans une norme de type C. Si une telle norme n'existe pas ou n'est pas adaptée, l'appréciation du risque et la détermination de mesures de protection adéquates relève de la responsabilité du fabricant de la machine.
Le présent document s'applique à tous les dispositifs de commande bimanuelle, indépendamment de l'énergie utilisée, y compris:
— les dispositifs de commande bimanuelle entièrement assemblés pour installation;
— les dispositifs de commande bimanuelle assemblés par le fabricant de machine ou l'intégrateur.
Le présent document n'est pas applicable aux dispositifs de commande bimanuelle fabriqués avant la date de sa publication.
Varnost strojev - Dvoročne krmilne naprave - Načela za načrtovanje in izbiro (ISO 13851:2019)
Ta evropski standard določa varnostne zahteve za dvoročne krmilne naprave in odvisnost izhodnega signala od vhodnih signalov ter opisuje glavne značilnosti dvoročnih krmilnih naprav za zagotavljanje varnosti in določa kombinacije funkcijskih značilnosti za tri tipe. Ne uporablja se za naprave, ki se uporabljajo kot vklopne, zadrževalne ali posebne krmilne naprave. Ta evropski standard podaja zahteve in smernice za načrtovanje in izbiro (na podlagi ocene tveganja) dvoročnih krmilnih naprav, vključno z njihovo oceno ter preprečevanjem odklopa in okvar. Prav tako podaja zahteve in smernice za dvoročne krmilne naprave, ki vsebujejo programirljive elektronske sisteme. Uporablja se za vse dvoročne krmilne naprave ne glede na uporabljeno energijo, vključno z dvoročnimi krmilnimi napravami, ki so ali niso sestavni del stroja, in dvoročnimi krmilnimi napravami, ki so sestavljene iz enega ali več ločenih elementov.
