Earth-moving machinery - Functional safety - Part 1: Methodology to determine safety-related parts of the control system and performance requirements (ISO/DIS 19014-1:2024)

This document provides a methodology for the determination of performance levels required for earth moving machinery (EMM) as defined in ISO 6165.
A Machine Control System Safety Analysis (MCSSA) determines the amount of risk reduction of hazards associated with control systems, required for Safety Control Systems (SCS). This reduction is quantified by the Machine Performance Level (MPL), the hazards are identified using the risk assessment principles as defined in ISO 12100 or by other means.
NOTE 1 Step 2 as shown in Annex A demonstrates the relationship between ISO 12100 and ISO 19014 as a complementary protective measure.
NOTE 2 ISO 19014 can also be used to assess the functional safety requirements of other off-road mobile machinery.
For those controls determined to be safety-related, the characteristics for architecture, hardware, software environmental requirements and performance are covered by other parts in ISO 19014.
ISO 19014 covers the hazards caused by the failure of a safety control system and excludes hazards arising from the equipment itself (for example, electric shock, fire, etc.).
Other controls that are not safety control systems (SCS), that do not mitigate a hazard or perform a control function and where the operator would be aware of a failure, are excluded from this standard (e.g. windscreen wipers, head lights, cab light, etc.).
NOTE 3 A list of safety control systems is included in Annex D.
NOTE 4 Audible warnings are excluded from the requirements of diagnostic coverage.

Erdbaumaschinen - Funktionale Sicherheit - Teil 1: Methodik zur Bestimmung sicherheitsbezogener Teile der Steuerung und deren Leistungsanforderungen (ISO/DIS 19014-1:2024)

Dieses Dokument enthält eine Methode zur Bestimmung der Performance Levels, die für Erdbaumaschinen (EMM), wie in ISO 6165 definiert, erforderlich sind.
Eine Sicherheitsanalyse der Maschinensteuerung (MCSSA) bestimmt die Höhe der Risikominderung bei Gefährdungen in Zusammenhang mit der Steuerung, die für Sicherheitssteuerungen (SCS) erforderlich ist. Diese Minderung wird durch das Performance Level der Maschine (MPL) quantifiziert und die Gefährdungen werden anhand der in ISO 12100 oder durch andere Mittel definierten Risikobeurteilungsgrundlagen identifiziert.
ANMERKUNG 1   Der in Anhang A dargestellte Schritt 2 zeigt den Zusammenhang zwischen ISO 12100 und ISO 19014 als ergänzende Schutzmaßnahme auf.
ANMERKUNG 2   ISO 19014 kann auch für funktionale Sicherheitsanforderungen anderer mobiler Geländemaschinen verwendet werden.
Für diese als sicherheitsbezogen festgelegten Stellteile werden die Merkmale für die Architektur, die Hardware, die Umgebungsanforderungen für die Software und die Leistung von anderen Teilen von ISO 19014 abgedeckt.
ISO 19014 deckt die Gefährdungen ab, die durch den Ausfall der Sicherheitssteuerungen verursacht werden, mit Ausnahme von Gefährdungen, die aufgrund der Ausrüstung selbst entstehen (z. B. elektrische Schläge, Brände usw.).
Andere Stellteile, die keine Sicherheitssteuerungen (SCS) darstellen, eine Gefährdung nicht mindern oder keine Steuerfunktion ausüben und die den Bediener auf Ausfälle aufmerksam machen, sind von dieser Norm ausgeschlossen (z. B. Scheibenwischer, Scheinwerfer, Kabinenbeleuchtung usw.).
ANMERKUNG 3   Anhang D enthält eine Liste an Sicherheitssteuerungen.
ANMERKUNG 4   Akustische Signale sind von den Anforderungen des Diagnosedeckungsgrads ausgeschlossen.

Le présent document fournit une méthode pour la détermination des niveaux de performance requis pour les engins de terrassement (EMM), comme définit dans l'ISO 6165.
Une analyse de sécurité des systèmes de commande de la machine (MCSSA) détermine le degré de réduction des phénomènes dangereux associés aux systèmes de commande requis pour les systèmes de commande de sécurité (SCS). Cette réduction est quantifiée par le niveau de performance de la machine (MPL), les phénomènes dangereux sont identifiés selon les principes d'évaluation des risques définis dans la norme ISO 12100 ou par d'autres moyens.
NOTE 1: La deuxième étape, comme présenté dans l'Annexe A, démontre la relation entre l'ISO 12100 et l'ISO 19014 en tant que mesure complémentaire.
NOTE 2: L'ISO 19014 peut également être utilisée pour évaluer les exigences de sécurité fonctionnelle d'autres machines mobiles non routières.
Pour ce qui est des commandes déterminées comme étant relatives à la sécurité, les caractéristiques d'exigences et de performances environnementales de l'architecture, du matériel et du logiciel sont couvertes dans d'autres parties de l'ISO 19014.
L'ISO 19014 couvre les phénomènes dangereux dus au disfonctionnement fonctionnel d'un système de commande lié à la sécurité, et exclut les phénomènes dangereux dus à l'équipement lui-même (par exemple, choc électrique, incendie, etc.).
Les autres commandes qui ne sont pas des systèmes de commande de sécurité (SCS), qui n'atténuent pas un phénomène dangereux ni ne réalisent une fonction de commande, et les cas où les défaillances pourraient être constatées par l'opérateur, sont exclus de la présente norme (par exemple, les essuie-glaces, les phares, l'éclairage de cabine, etc.).
NOTE 3: Une liste de fonctions de sécurité est incluse dans l'Annexe D.
NOTE 4: Les avertisseurs sonores sont exclus des exigences de la couverture de diagnostic.

Foreword
ISO (the International Organization for Standardization) is a worldwide federation of national standards
bodies (ISO member bodies). The work of preparing International Standards is normally carried out
through ISO technical committees. Each member body interested in a subject for which a technical
committee has been established has the right to be represented on that committee. International
organizations, governmental and non-governmental, in liaison with ISO, also take part in the work.
ISO collaborates closely with the International Electrotechnical Commission (IEC) on all matters of
electrotechnical standardization.
The procedures used to develop this document and those intended for its further maintenance are
described in the ISO/IEC Directives, Part 1. In particular, the different approval criteria needed for the

Introduction
This document addresses systems of all energy types used for functional safety in earth-moving
machinery.
The structure of safety standards in the field of machinery is as follows.
Type-A standards (basis standards) give basic concepts, principles for design and general aspects that
can be applied to machinery.
Type-B standards (generic safety standards) deal with one or more safety aspects, or one or more types
of safeguards that can be used across a wide range of machinery:
— type-B1 standards on particular safety aspects (e.g. safety distances, surface temperature, noise);
— type-B2 standards on safeguards (e.g. two-hands controls, interlocking devices, pressure sensitive
devices, guards).
Type-C standards (machinery safety standards) deal with detailed safety requirements for a particular
machine or group of machines.
This document is a type C standard as stated in ISO 12100.
This document is of relevance, in particular, for the following stakeholder groups representing the
market players with regard to machinery safety:
— machine manufacturers (small, medium and large enterprises);
— health and safety bodies (regulators, accident prevention organisations, market surveillance etc.).
Others can be affected by the level of machinery safety achieved with the means of the document by the
above-mentioned stakeholder groups:
— machine users/employers (small, medium and large enterprises);
— machine users/employees (e.g. trade unions, organizations for people with special needs);
— service providers, e. g. for maintenance (small, medium and large enterprises);
— consumers (in case of machinery intended for use by consumers).
The above-mentioned stakeholder groups have been given the possibility to participate at the drafting
process of this document.
The machinery concerned and the extent to which hazards, hazardous situations or hazardous events
are covered are indicated in the Scope of this document.
When requirements of this type-C standard are different from those which are stated in type-A or
type-B standards, the requir
