EN 16590-2:2014

Tractors and machinery for agriculture and forestry - Safety-related parts of control systems - Part 2: Concept phase (ISO 25119-2:2010 modified)

This part of EN 16590 specifies the concept phase of the development of safety-related parts of control systems (SRP/CS) on tractors used in agriculture and forestry, and on self-propelled ride-on machines and mounted, semi-mounted and trailed machines used in agriculture. It can also be applied to municipal equipment (e.g. street sweeping machines). It specifies the characteristics and categories required of SRP/CS for carrying out their safety functions.
This part of EN 16590 is applicable to the safety-related parts of electrical/electronic/programmable electronic systems (E/E/PES), as these relate to mechatronic systems. It does not specify which safety functions, categories or performance levels are to be used for particular machines.
Machine specific standards (type-C standards) can identify performance levels and/or categories or they should be determined by the manufacturer of the machine based on risk assessment.
It is not applicable to non-E/E/PES systems (e.g. hydraulic, mechanic or pneumatic).

Traktoren und Maschinen für die Land- und Forstwirtschaft - Sicherheitsbezogene Teile von Steuerungen - Teil 2: Konzeptphase (ISO 25119-2:2010 modifiziert)

Dieser Teil der EN 16590 beschreibt die Konzeptphase der Entwicklung sicherheitsbezogener Teile von Steuerungen (SRP/CS) in land- und forstwirtschaftlichen Traktoren, selbstfahrenden Aufsitzmaschinen sowie Anbau-, Aufsattel- und Anhängemaschinen für landwirtschaftliche Geräte. Sie kann auch auf kommunale Geräte (z. B. Straßenkehrmaschinen) angewendet werden. Sie beschreibt Merkmale und Kategorien, die zur Ausführung sicherheitsrelevanter Funktionen durch SRP/CS-Systeme erforderlich sind.
Dieser Teil der EN 16590 gilt für sicherheitsbezogene Teile elektrischer/elektronischer/programmierbarer elektronischer Systeme (E/E/PES) als Teil mechatronischer Systeme. Sie schreibt jedoch nicht vor, welche Sicherheitsfunktionen, Kategorien oder Performance Levels für bestimmte Maschinen anzuwenden sind.
Maschinensicherheitsnormen (Typ-C-Normen) können entweder Performance Levels und/oder Kategorien selbständig identifizieren oder sie sollten durch den Maschinenhersteller auf Basis einer Risikobeurteilung festgelegt werden.
Sie ist nicht anzuwenden auf nicht-E/E/PES Systeme (z. B. hydraulische, mechanische und pneumatische).

Tracteurs et matériels agricoles et forestiers - Parties des systèmes de commande relatives à la sécurité - Partie 2: Phase de projet (ISO 25119-2:2010 modifié)

La présente partie de l’EN 16590 spécifie la phase de conception du développement des parties relatives à la sécurité des systèmes de commande (SRP/CS) utilisés sur les tracteurs agricoles et forestiers, sur les machines automotrices à conducteur porté et sur les machines portées, semi-portées et remorquées utilisées en agriculture. Elle peut être également applicable aux équipements municipaux (par exemple machines de balayage des rues). Elle spécifie les caractéristiques et les catégories requises des SRP/CS pour réaliser leurs fonctions de sécurité.
La présente partie de l’EN 16590 s'applique aux parties relatives à la sécurité des systèmes électriques/électroniques/électroniques programmables (E/E/PES). Dans la mesure où celles-ci sont liées aux systèmes mécatroniques, elle ne spécifie ni les fonctions de sécurité ni les catégories censées être utilisées dans un cas particulier.
Les normes spécifiques (normes de type-C) peuvent identifier les niveaux de performance et/ou catégories ou il convient qu’ils soient déterminés par le fabricant de la machine sur la base de l’évaluation du risque.
Elle n'est pas applicable aux systèmes non-E/E/PES (par exemple hydraulique, mécanique et pneumatique).

Traktorji ter kmetijski in gozdarski stroji - Varnostni deli krmilnih sistemov - 2. del: Faza koncepta (ISO 25119-2:2010, spremenjen)

Standard EN 16590-2 določa fazo zasnove za projektiranje in razvoj varnostnih delov krmilnih sistemov (SRP/CS) za traktorje, ki se uporabljajo v kmetijstvu in gozdarstvu, in za samognane stroje s sedežem ter za priklopne, polpriklopne in vlečene stroje, ki se uporabljajo v kmetijstvu. Uporablja se lahko tudi za komunalno opremo (npr. za pometalne stroje). Določa lastnosti in kategorije, ki so zahtevane za SRP/CS, da lahko ti izvajajo svoje varnostne funkcije. Ta del standarda EN 16590 se uporablja za varnostne dele električnih/elektronskih/programirljivih elektronskih sistemov (E/E/PES), saj so ti povezani z mehatronskimi sistemi. Ne določa, katere varnostne funkcije, kategorije ali ravni delovanja je treba uporabiti za posamezne stroje. Standardi, značilni za stroje (standardi tipa C), lahko določajo ravni zmogljivosti in/ali kategorije oziroma naj bi jih določil proizvajalec stroja glede na oceno tveganja.
