Overview
EN ISO 8846:2017 - "Small craft - Electrical devices - Protection against ignition of surrounding flammable gases" (ISO 8846:1990 adopted by CEN) specifies test methods and design requirements so electrical equipment used on small craft can be operated in potentially explosive atmospheres without igniting surrounding flammable gases. It defines practical ignition‑protection tests (surface temperature, sealed and non‑sealed device tests) and is intended to support conformity with EU Directive 2013/53/EU for pleasure craft components.
Key topics and technical requirements
- Scope and exclusions
- Covers electrical devices intended for small craft and protection against surrounding hydrocarbon fuel/air atmospheres (propane–air mixtures between the LEL and UEL).
- Does not require explosion‑proof apparatus as defined by IEC 79‑0 and does not address ignition mechanisms from external sources (static, lightning) or hydrogen/oxygen mixtures from vented batteries.
- External surface temperature test
- Devices are operated in a circulating oven (initial temperature 60 °C ± 2 °C) for at least 7 hours at the worst‑case operating condition.
- Test voltage = 80 % to 120 % of nominal system voltage producing the greatest temperature rise.
- Maximum allowable external surface temperature = 200 °C at any point.
- Sealed device test (clause 5)
- Submerge device in a water chamber to check for leakage (15 minutes per attitude).
- If no water ingress is found after dismantling, the device is accepted as sealed and ignition‑protected.
- If ingress occurs, the device must be tested as non‑sealed.
- Non‑sealed device test (clause 6)
- Uses a test chamber with a propane–air mixture (representative marine fuel/air concentration; mixture guidance in the standard).
- Electrical device is supplied with the explosive mixture via tubing/vent and a spark gap or spark‑plug simulates internal sparking.
- Procedure requires multiple ignition cycles and verification that chamber ignition does not occur from the device; failures require purging and retesting.
Applications and users
- Who uses it: marine electrical equipment designers, small craft engine and accessory manufacturers, conformity assessors, test laboratories, certification bodies, boat builders and safety regulators.
- Practical use cases: designing ignition‑protected starters, switches, pumps and instruments; type‑testing components for inboard engine compartments, petrol tank spaces and other fuel‑exposed zones; demonstrating conformity with EU Directive 2013/53/EU.
Related standards
- ISO 8846:1990 (original text adopted)
- Supersedes EN 28846:1993
- References/exclusions: IEC 79‑0 (explosion‑proof apparatus) and EU Directive 2013/53/EU (essential requirements)
EN ISO 8846:2017 is fundamental for ensuring electrical devices for small craft do not act as ignition sources in flammable gas atmospheres - essential for marine safety, regulatory compliance and product certification.

Foreword
IS0 (the International Organization for Standardization) is a worldwide
federation of national standards bodies (IS0 member bodies). The work
of preparing International Standards is normally carried out through IS0
technical committees. Each member body interested in a subject for
which a technical committee has been establishetl has the right to be
represented on that committee. International organizations, govern-
mental and non-governmental, in liaison with ISO, also take part in the
work. IS0 collaborates closely with the InternatL3nal Electrotechnical
Commission (IEC) on all matters of electrotechnical standardization.
Draft International Standards adopted by the technical committees are
circulated to the member bodies for voting. Publication as an lnter-
national Standard req:lires approval by at least 75 % of the member
bodies casting a vote.

The SIST EN ISO 8846:2017 standard addresses the critical issue of safety in small craft by offering comprehensive test methods and design requirements for electrical devices. This standard is integral for ensuring that such devices can function safely within environments that may contain flammable gases. One of the key strengths of this standard is its thorough approach to defining operational parameters that electrical devices must meet to prevent ignition in potentially explosive atmospheres. By specifying rigorous testing protocols, the standard ensures that manufacturers adhere to stringent safety measures, enhancing the reliability of small craft operations. Additionally, the relevance of SIST EN ISO 8846:2017 cannot be overstated, particularly for stakeholders in the maritime industry, including manufacturers, designers, and regulatory bodies. The emphasis on protecting against ignition not only helps in safeguarding the lives of individuals on board but also protects the integrity of the craft and the environment. Furthermore, this standard plays a vital role in standardizing safety practices across different regions, facilitating international trade in small craft and their components. Adopting the provisions of SIST EN ISO 8846:2017 helps to ensure that products meet global safety expectations, thereby fostering trust and transparency in the market. In conclusion, the SIST EN ISO 8846:2017 standard stands out for its detailed framework aimed at mitigating the risks associated with electrical devices in explosive atmospheres, making it an essential reference document for ensuring safety in the use of small craft within such environments.
Die SIST EN ISO 8846:2017 ist eine entscheidende Norm, die spezifische Testmethoden und Anforderungen für die Gestaltung elektrischer Geräte beschreibt, die auf kleinen Wasserfahrzeugen eingesetzt werden. Ihr Hauptziel ist es, sicherzustellen, dass diese Geräte in explosionsgefährdeten Umgebungen betrieben werden können, ohne die umliegenden brennbaren Gase zu entzünden. Ein zentraler Stärke dieser Norm liegt in ihrer umfassenden Anwendbarkeit auf alle Arten von kleinen Booten, was ihre Relevanz für die maritime Branche deutlich erhöht. Die Norm gewährleistet nicht nur die Sicherheit von Personen an Bord, sondern schützt auch die Umwelt vor möglichen Gefahren durch Explosionen. Die festgelegten Testmethoden sind klar definiert und ermöglichen eine einfache Implementierung der Sicherheitsanforderungen in den Designprozess elektrischer Geräte. Darüber hinaus fördert die SIST EN ISO 8846:2017 das Vertrauen in maritime Produkte, da Hersteller nachweislich die geforderten Standards einhalten müssen. Dadurch wird auch die Internationalität der Norm unterstrichen, da sie auf den ISO 8846:1990 Standards basiert und somit weltweit anerkannt ist. Zusammenfassend lässt sich sagen, dass die SIST EN ISO 8846:2017 die Sicherheitsstandards für elektrische Geräte auf kleinen Wasserfahrzeugen erheblich verbessert und ihre Relevanz durch die Berücksichtigung von Prüfmethoden und Sicherheitsanforderungen unterstreicht.
La norme SIST EN ISO 8846:2017 est un document essentiel pour la sécurité des dispositifs électriques sur les petites embarcations. Son champ d'application se concentre sur les méthodes d'essai et les exigences de conception des dispositifs électriques qui se doivent d'être opérationnels dans des atmosphères explosives. Cela permet d'assurer que les appareils utilisés sur ces embarcations ne déclenchent pas l'inflammation des gaz inflammables présents dans l'environnement. Parmi les points forts de cette norme, on trouve son approche systématique pour tester la résistance à l'ignition des équipements. Les exigences de conception y sont clairement définies, garantissant ainsi une standardisation qui favorise l'homogénéité des produits sur le marché. De plus, l’adoption de cette norme internationale contribue à améliorer la sécurité globale des utilisateurs de petites embarcations, en fournissant des critères spécifiques que les fabricants doivent respecter. En intégrant ces exigences dans le processus de fabrication, les entreprises peuvent non seulement se conformer aux réglementations, mais aussi renforcer la confiance des consommateurs dans la sécurité de leur équipement. La pertinence de la norme SIST EN ISO 8846:2017 réside donc dans sa capacité à protéger les usagers et à réduire les risques d'accidents liés à l'ignition des gaz inflammables, faisant d'elle un document incontournable pour le secteur nautique.
