Earth-moving machinery - Functional safety - Part 2: Design and evaluation of hardware and architecture requirements for safety-related parts of the control system (ISO/DIS 19014-2:2024)

This document specifies general principles for the development and evaluation of the machine performance level achieved (MPLa) of safety-control systems (SCS) using components powered by all energy sources (e.g. electronic, electrical, hydraulic, mechanical) used in earth-moving machinery and its equipment, as defined in ISO 6165.
The principles of this document apply to machine control systems (MCS) that control machine motion or mitigate a hazard; such systems are assessed for machine performance level required (MPLr) per ISO 19014-1 or ISO/TS 19014-5.
Excluded from the scope of this document are the following systems:
—    awareness systems that do not impact machine motion (e.g. cameras and radar detectors);
—    fire suppression systems, unless the activation of the system interferes with, or activates, another SCS.
Other systems or components whereby the operator would be aware of failure (e.g. windscreen wipers, head lights, etc.), or are primarily used to protect property, are excluded from this document. Audible warnings are excluded from the requirements of diagnostic coverage.
In addition, this document addresses the significant hazards as defined in ISO 12100 mitigated by the hardware components within the SCS.
This document is not applicable to EMM manufactured before the date of its publication.

Erdbaumaschinen - Funktionale Sicherheit - Teil 2: Entwurf und Bewertung von Hardware- und Architekturanforderungen für sicherheitsrelevante Teile des Steuerungssystems (ISO/DIS 19014-2:2024)

Dieses Dokument legt allgemeine Grundsätze für die Entwicklung und Beurteilung des erreichten Performance Level der Maschine (MPLa) bei Sicherheitssteuerungen (SCS), unter Verwendung von Komponenten, die durch sämtliche, bei Erdbaumaschinen und deren Ausrüstung, wie in ISO 6165 festgelegt, Energiequellen (z. B. elektronisch, elektrisch, hydraulisch, mechanisch) angetrieben werden, fest.
Die Grundsätze dieses Dokuments sind anwendbar für Steuerungssysteme zur Steuerung von Maschinenbewegungen oder Verminderung von Gefährdungen. Solche Systeme werden nach ISO 19014 1:202X oder ISO 19014 5:202X hinsichtlich der Anforderungen an das Performance Level (MPLr) untersucht.
Folgende Systeme sind vom Anwendungsbereich dieses Dokuments ausgeschlossen:
   Wahrnehmungssysteme, die die Maschinenbewegung nicht beeinflussen (z. B. Kameras und Radardetektoren);
   Löschanlagen, sofern die Aktivierung des Systems kein anderes SCS beeinflusst oder aktiviert.
Weitere Systeme oder Komponenten, die den Bediener auf Ausfälle aufmerksam machen (z. B. Scheibenwischer oder Scheinwerfer usw.) oder die primär dem Schutz von Eigentum dienen, sind von diesem Dokument ausgeschlossen. Akustische Signale sind von den Anforderungen des Diagnosedeckungsgrads ausgeschlossen.
Zudem behandelt dieses Dokument die in ISO 12100 festgelegten signifikanten Gefährdungen, die durch die Hardwarekomponenten der SCS gemindert werden.
Dieses Dokument gilt nicht für EMM, die vor dem Veröffentlichungsdatum dieses Dokuments hergestellt wurden.

Engins de terrassement - Sécurité fonctionnelle - Partie 2: Conception et évaluation des exigences de matériel et d’architecture pour les parties relatives à la sécurité du système de commande (ISO/DIS 19014-2:2024)

Le présent document spécifie les principes généraux d’élaboration et d’évaluation du niveau de performance de machine obtenu (MPLa) des systèmes de commande de sécurité (SCS) utilisant des composants alimentés par toutes les sources d’énergie (par exemple, électronique, électrique, hydraulique, mécanique) utilisées dans les engins de terrassement et leur équipement, comme défini dans l’ISO 6165.
Les principes du présent document s’appliquent aux systèmes de commande d’engins (MCS) qui commandent le mouvement d’un engin ou atténuent un phénomène dangereux; ces systèmes sont évalués pour vérifier que les exigences de niveau de performance des engins (MPLr) sont conformes à l’ISO 19014‑1 ou à l’ISO/TS 19014‑5.
Les systèmes suivants sont exclus du domaine d’application du présent document:
—    systèmes de connaissance n’ayant aucun impact sur le mouvement de l'engin (par exemple, caméras et détecteurs radar);
—    systèmes de lutte contre l’incendie, excepté si l’activation du système interfère ou active un autre SCS.
Les autres systèmes ou composants pour lesquels les défaillances pourraient être constatées par l’opérateur (par exemple, les essuie-glaces, les phares, l’éclairage de la cabine, etc.) ou ceux qui servent essentiellement à protéger la propriété sont exclus du présent document. Les avertisseurs sonores sont exclus des exigences de la couverture de diagnostic.
De plus, le présent document traite des phénomènes dangereux significatifs tels que définis dans l’ISO 12100 atténués par les composants matériels dans le SCS.
Le présent document n’est pas applicable aux engins de terrassement fabriqués avant la date de sa publication.
