ISO 15736:2006

Overview

ISO 15736:2006 specifies production testing, inspection and marking requirements for pyrotechnic life‑saving appliances used on ships. It is intended to be used with the IMO Life‑Saving Appliance (LSA) Code and the IMO Recommendation on testing of life‑saving appliances to assess conformity of production units (rockets, hand flares, buoyant smoke signals, lifebuoy smoke units, and line‑throwing appliances) for ships subject to SOLAS. The standard defines manufacturing quality‑control expectations, sampling and inspection procedures, performance criteria and mandatory markings.

Key topics and technical requirements

• Scope and applicability: Applies to devices type‑approved under the IMO LSA Code; principles may be used for non‑IMO products where appropriate.
• Manufacturing quality control: Requires manufacturers to maintain a quality system to ensure production matches prototype approval; Annex A provides recommended production testing and inspection procedures. ISO 2859‑1 sampling schemes are referenced for lot inspection.
• Marking and documentation:
  • Mandatory markings on each production unit: model, functional data (altitude, burn time, candela), “SOLAS 96” or “IMO LSA Code”, “ISO 15736”, manufacturer name, month/year of manufacture, approval information.
  • Expiry date: Permanently marked; default service life 36 months from manufacture unless extended by administration.
  • Transport packaging must follow UN Recommendations on the Transport of Dangerous Goods.
  • Retention of prototype and lot production records for production life + at least three years after expiry.
• Performance criteria (selected highlights):
  • Rocket parachute flare: expulsion altitude ≥ 300 m, luminous intensity ≥ 30 000 cd, burn time ≥ 40 s, descent rate ≤ 5 m/s, vivid red colour (≈ 608 nm ±11 nm).
  • Hand flare: luminous intensity ≥ 15 000 cd, burn time ≥ 1 min, operational delay if applicable 3.0 s ±1.0 s.
  • Buoyant smoke signal: orange smoke, ≥ 70% obscuration, emission time ≥ 3 min (lifebuoy self‑activating signal ≥ 15 min), no flame.
  • Line‑throwing appliances: range ≥ 230 m, lateral deflection ≤ 10% of flight length, wet line breaking strength ≥ 2 kN.
• Test procedures: Photometric/luminous intensity, thrust vs time, altitude/triangulation, temperature cycling, immersion, cold/hot testing, smoke density and colour, burn time, and line‑throw function tests.

Applications and users

ISO 15736:2006 is used by:

• Manufacturers of pyrotechnic life‑saving appliances for production control and marking compliance.
• Maritime administrations and certification bodies for conformity assessment and type‑approval follow‑up.
• Test laboratories performing photometric, combustion and range tests.
• Ship operators and procurement teams specifying compliant SOLAS/LSA equipment.
