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.
