Overview

ISO/FDIS 8528-13 - Reciprocating internal combustion engine driven AC generating sets - Part 13: Safety specifies safety requirements for reciprocating internal combustion (RIC) engine driven generating sets up to 1 000 V. The standard covers the RIC engine, the AC generator and additional equipment required for operation (controlgear, switchgear, auxiliary equipment). It applies to land and non‑seagoing marine use (domestic, recreational and industrial applications), but excludes generating sets used aboard seagoing vessels, mobile offshore units, aircraft, road vehicles, locomotives and arc welding equipment. The document identifies significant hazards (Annex A) and defines test and safety‑design requirements to protect users.

Key topics and technical requirements

The standard addresses safety design, testing and user information across the lifecycle of a generating set. Major technical topics include:

  • Starting, stopping and emergency stop systems - requirements and verification for safe control of engine operation.
  • Control and monitoring devices - design, identification, accessibility and verification of controls and monitoring instrumentation.
  • Guarding and protection - mechanical guards, protection from hot surfaces and moving parts, and requirements for low‑power portable units.
  • Electrical safety - degree of protection (IP), insulation, protective bonding circuits and other electrical equipment safeguards.
  • Fire protection and drainage - fire safety measures and management of fuel/oil/drainage to reduce fire and environmental risk.
  • Hoses, pipes and harnesses - routing, securing and verification of engine and electrical harnesses.
  • Stability, handling and access systems - requirements for stability in operation, lifting/handling points and safe access to service areas.
  • Noise, exhaust emissions and lighting - requirements and verifications for operator safety and environmental considerations.
  • Information for use - operating/maintenance instructions, safety labels and marking requirements (including Annex D guidance for low‑power units for laypersons).
  • Verification and testing - prescriptive verification steps tied to each safety requirement.

Practical applications and users

ISO 8528-13 is intended for:

  • Manufacturers and designers of RIC engine driven generating sets (product design, safety engineering).
  • Testing and certification bodies conducting compliance and type‑approval testing.
  • Installers and system integrators specifying controlgear, switchgear and safety measures for installed generators.
  • Maintenance and safety personnel using the information for safe operation, servicing and labeling.
  • Procurement and compliance teams ensuring equipment meets recognized international safety requirements.

Using this standard helps reduce mechanical, electrical, fire and exhaust hazards, improves user instructions and supports regulatory compliance for generator safety.

4 Exigences de sécurité et/ou mesures de protection/réduction des risques et
vérification
4.1 Généralités
Les machines doivent être conformes aux exigences de sécurité et/ou aux mesures de prévention/réduction
des risques du présent article.
En outre, les machines doivent être conçues conformément aux principes énoncés dans l’ISO 12100:2010 en
ce qui concerne les phénomènes dangereux pertinents mais non significatifs qui ne sont pas traités dans le
présent document.
Les phénomènes dangereux relatifs aux groupes électrogènes entraînés par moteurs alternatifs à combustion
interne qui doivent être pris en compte afin de prévenir les dommages corporels sont énumérés dans le
Tableau A.1.
4.2 Dispositif de démarrage
4.2.1 Exigences
Les dispositifs de démarrage peuvent être déclenchés manuellement ou automatiquement.
Les dispositifs de démarrage électriques fonctionnent normalement à des tensions inférieures ou égales à
24 V. Les dispositifs de démarrage électriques de plus de 24 V ne sont pas traités dans le présent document
et l’installateur du moteur doit s’assurer du fonctionnement en sécurité après le raccordement du moteur
aux machines entraînées.
Pour les moteurs équipés d’un dispositif de démarrage à air comprimé, le circuit pneumatique de démarrage
doit être conforme aux exigences d’installation et aux consignes de fonctionnement et de sécurité spécifiées
dans les manuels fournis par les fournisseurs de composants du dispositif de démarrage.
— Les manivelles de démarrage doivent présenter un dégagement suffisant par rapport à leurs surface de
montage pour assurer leur rotation en toute sécurité.
— Les moteurs diesel à démarrage manuel doivent comporter un dispositif de décompression qui ne doit
pas exiger d’être tenu à la main pendant le démarrage.
Les seuls dispositifs de démarrage manuel autorisés sont les dispositifs de démarrage à manivelle
(tels que définis ci-dessus) et à réenrouleur conformément à l’ISO 14314:2014. Le marquage exigé dans
l’ISO 14314:2014, 7.3 ne doit pas s’appliquer.

4.2.2 Vérification
La conformité aux exigences doit être vérifiée par des contrôles et des essais des dispositifs de démarrage.
4.3 Arrêt
4.3.1 Exigences
4.3.1.1 Arrêt normal
Chaque groupe électrogène doit comporter un interrupteur normal ou un autre dispositif d’arrêt normal qui
peut être actionné manuellement ou automatiquement. Les commandes d’arrêt doivent rester en position
d’arrêt lorsqu’elles ont été activées. Cela doit fonctionner à l’aide d’un dispositif assurant la coupure de
l’alimentation en carburant ou la coupure de l’allumage (moteur à allumage par étincelles).
4.3.1.2 Arrêt en cas de défaillance
Les groupes électrogènes, à l’exception des groupes électrogènes de faible puissance, doivent être munis
d’un dispositif d’arrêt à commande automatique en cas de défaillance.
Ce dispositif doit surveiller un ou plusieurs signaux du groupe électrogène et si ces signaux ne se trouvent
pas dans la plage admissible, le dispositif doit déclencher l’arrêt automatique.
De manière non limitative, les principaux signaux utilisables pour déclencher un arrêt automatique sont les
suivants:
a) pour le moteur alternatif à combustion interne:
1) une survitesse;
2) une pression basse d’huile de lubrification;
3) une température élevée du liquide de refroidissement; et
4) un niveau bas du liquide de refroidissement;
b) pour le générateur:
1) une surtension excessive; et
2) une surcharge.
Ces signaux ou les autres mesures utilisées pour déclencher un arrêt automatique doivent être spécifiés en
fonction de l’application.
4.3.2 Vérification
L’arrêt normal doit être vérifié par des contrôles et des essais du dispositif d’arrêt en mode manuel et en
mode automatique (s’ils sont présents dans l’application).
L’arrêt automatique en cas de défaillance doit être vérifié par des essais de l’action des modes de défaillance
types dans les conditions de fonctionnement (une méthode appropriée doit être utilisée pour créer des
conditions de défaillance types, par exemple déclenchement manuel, mise en court-circuit de contacts).
4.4 Arrêt d’urgence
4.4.1 Exigences
Des dispositifs d’arrêt d’urgence sont requis pour les groupes électrogènes à commande à distance et
pour les groupes électrogènes dont l’auvent ou l’enveloppe est accessible à du personnel. Conformément à

l’appréciation du risque spécifiée dans l’ISO 12100:2010, 6.3.5.2, un dispositif d’arrêt d’urgence n’est pas
requis pour les groupes électrogènes de faible puissance, car cela ne doit pas réduire le risque en diminuant
le temps d'arrêt.
Les dispositifs d’arrêt d’urgence doivent être à commande manuelle. Comme pour l’arrêt normal, l’arrêt
d’urgence doit être obtenu par un dispositif assurant la coupure de l’alimentation en carburant ou de
l’allumage (moteur à allumage par étincelles). Il convient que ce dispositif comporte une fermeture de
l’alimentation en air.
Les dispositifs d’arrêt d’urgence doivent être conformes à l’IEC 60204-1:2016/A1:2021, paragraphe 10.7.
Les dispositifs d’arrêt d’urgence doivent également satisfaire aux exigences de l’ISO 13850:2015, catégorie 0,
et leur réarmement ne doit provoquer ni redémarrage ni conditions dangereuses.
Les dispositifs d’arrêt d’urgence à commande manuelle doivent se situer à l’intérieur et à l’extérieur de
l’auvent ou de l’enveloppe dans lequel/laquelle un groupe électrogène est installé et qui est accessible à du
personnel pour des opérations d’entretien ou de commande lorsque les groupe électrogènes sont en service.
Pour les auvents, les enveloppes ou lorsqu’il n’y a aucun accès physique pour le personnel, au moins un
dispositif d’arrêt d’urgence doit être placé à l’extérieur.
4.4.2 Vérification
Les dispositifs d’arrêt d’urgence doivent être vérifiés par des contrô
