Overview

ISO 19292:2014 - Ships and marine technology - Lifesaving and fire protection - Point-type resettable flame detectors for ships - specifies performance criteria, test methods and maritime requirements for point-type, resettable flame detectors that operate by sensing radiation from a flame. Intended for fire detection systems installed on ships, the standard references ISO 7240-10 for common terrestrial/marine requirements and supplements it with shipboard-specific environmental and electromagnetic compatibility (EMC) tests needed for reliable marine flame detectors.

Key topics and technical requirements

ISO 19292:2014 focuses on functional performance and robustness of flame detectors in the shipboard environment. Key technical topics include:

• Scope and references: Aligns with ISO 7240-10 and ISO 7240-1; normative test standards include IEC 60068 series (environmental) and IEC 61000 series / CISPR 16 (EMC).
• Environmental conditioning tests:
  • Dry heat (operational): conditioning up to (70 ± 2) °C for 2 h, with functional checks.
  • Cold (operational): conditioning to (5 ± 3) °C, and for external/exposed detectors to (−25 ± 3) °C, 2 h.
  • Damp heat: cyclic conditioning at (55 ± 2) °C, 95% RH for 24 h cycles.
  • Salt mist: cyclic sodium chloride exposure to simulate corrosive marine atmospheres.
  • Vibration (sinusoidal): operational vibration testing per IEC 60068-2-6.
• EMC and electrical robustness:
  • Electrostatic discharge (IEC 61000-4-2), radiated RF immunity, conducted disturbance immunity (IEC 61000-4-6), burst/fast transient, surge immunity (IEC 61000-4-5), and radiated emissions.
  • Tests for variation in supply parameters, high voltage, power-supply failure and insulation resistance.
• Performance criteria:
  • Functional verification during and after conditioning; no false alarms or faults during transitions.
  • Response point stability - example: ratio of maximum to minimum response points (Dmax/Dmin) shall not exceed 1.26 for certain tests.

Practical applications and users

ISO 19292:2014 is used by:

• Detector manufacturers to design, test and certify marine-rated, point-type resettable flame detectors.
• Shipbuilders and system integrators specifying fire detection systems for SOLAS-regulated vessels and installations subject to the FSS Code.
• Classification societies and maritime regulators assessing compliance for shipboard fire detection equipment.
• Test laboratories conducting environmental and EMC testing for marine approvals.
• Ship operators and safety engineers selecting robust flame detectors for engine rooms, cargo spaces and open-deck installations.

Adopting ISO 19292 helps ensure reliable flame detection in harsh shipboard conditions, reducing false alarms and improving crew safety and regulatory compliance.

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.

Introduction
The 1974 International Convention for the Safety of Life at Sea (SOLAS 1974), as amended, and its
associated International Code for Fire Safety Systems (FSS Code) require certain ships to be fitted with
fixed fire detection and fire alarm systems, and provide general requirements for such systems.
This International Standard has been developed to supplement the provisions of SOLAS 1974 and the
FSS Code by specifying detailed performance criteria and test methods for point-type resettable flame
detectors for use in fire detection on ships.
This International Standard has been prepared by Sub-committee ISO/TC 8/SC 1 for point-type,
resettable flame detectors on board ships to replace Annex A of ISO 7240-10:2007. This International
Standard is based on the performance standards for terrestrial flame detectors in ISO 7240-10 and
provides alternative requirements for flame detectors for use in marine applications.
