Описание (английский):

This document specifies test methods and requirements for the design of electrical devices, when under normal operating conditions, on small craft so that they can be operated without igniting a surrounding flammable gas atmosphere. This document does not apply to ignition protection procedures for: — devices or components that can operate in hydrogen and air mixtures; — devices with dysfunctional issues; — mechanisms of ignition from external sources, such as static electricity, lightning or other factors not related to the equipment under test.

Abstract

Overview

EN ISO 8846:2026 sets out test methods and requirements to ensure that electrical devices on small craft operate safely in environments where flammable gases may be present. Developed by CEN in collaboration with ISO, this European Standard focuses on minimizing the risk of ignition from onboard electrical equipment, especially in areas like engine compartments and fuel tank spaces. By applying these requirements, manufacturers can ensure compliance with safety obligations, particularly those outlined in EU Directive 2013/53/EU related to recreational craft.

The standard is relevant to electrical equipment installed on small craft - boats and vessels up to 24 meters in length. It specifies requirements for devices during normal use, excluding special cases such as hydrogen atmospheres, equipment malfunction, or ignition from external sources like lightning.

Key Topics

Scope of Application
- Applies to electrical devices in small craft subject to flammable hydrocarbon gas atmospheres.
- Focuses on protection against ignition caused by external device temperatures or internal electrical arcs.
- Excludes protection for hydrogen environments, devices with known faults, and ignition from static or lightning.
Design and Testing Requirements
- Devices must not ignite surrounding flammable gas under normal operating conditions.
- Requirements address both sealed and non-sealed devices, with specific test methods for each.
- Surface temperature tests ensure components do not exceed safe external temperatures.
- For sealed devices, integrity is verified by submersion tests to check for ingress.
- Non-sealed devices undergo chamber tests simulating gas exposure and potential ignition events.
Identification and Labeling
- Compliant products must display the marking “ISO 8846 MARINE” or “Ignition Protected”, with durable labeling suitable for harsh marine conditions.

Applications

Marine Electrical Equipment Manufacturing
- Critical for manufacturers of starters, alternators, pumps, switches, and circuit breakers designed for use in motorboats, yachts, and other small craft.
- Assists in risk evaluations during product design and safety assurance processes.
System Integrators and Boat Builders
- Essential guidance for selection and installation of electrical systems where flammable gases could accumulate (e.g., petrol engine compartments, LPG gas lockers).
- Facilitates selection of components that comply with both safety best practices and legal requirements.
Regulatory Compliance
- Supports compliance with EU legislation for recreational craft, notably Directive 2013/53/EU.
- Contributes to CE marking and declaration of conformity processes for marine products.
