Overview
SIST EN ISO 12402-9:2020 - Personal flotation devices - Part 9: Evaluation specifies the evaluation processes and test methods used to determine whether personal flotation devices (PFDs) meet the requirements of ISO 12402‑2:2020 to ISO 12402‑6:2020. Adopted as EN ISO 12402-9:2020 and published by ISO/CEN (also implemented by SIST), this second edition supersedes the 2006 version and consolidates mechanical, buoyancy and human performance test procedures needed for conformity assessment of lifejackets, buoyancy aids and inflatable PFDs.
Key topics and technical requirements
The standard focuses on practical, repeatable evaluation methods rather than prescribing performance limits itself. Major technical topics include:
- Sampling and conditioning - procedures for selecting test samples and preparing PFDs for test.
- Mechanical properties tests - rotating shock bin, temperature cycling, horizontal/vertical load, lifting-loop, buddy-line, collar handles, hardware secureness and attachment strength for inflatable chambers.
- Inflation and buoyancy tests - inflation tests, measurement of whole-device buoyancy, uninflated material buoyancy and revised measurement procedures.
- Safety and durability checks - resistance to burning, overpressure testing, and tests for inadvertent inflation.
- Magnetic properties testing - procedures for assessing magnetic materials that may affect rescue electronics.
- Human-subject performance tests - donning, water-entry, self-righting and stability, freeboard measurement, in‑water stability, boarding and oral inflation tests using representative human subjects.
- Manikin tests - fall-from-height, mouth freeboard and self-righting assessments using standardized manikins.
- Normative reference equipment - defined adult and child reference vests and a manikin in annexes used for test subject qualification and validation.
(Annex A provides the PFD classification used across the ISO 12402 series.)
Practical applications and who uses this standard
SIST EN ISO 12402-9:2020 is essential for:
- Manufacturers and product designers validating new lifejacket and buoyancy aid designs.
- Independent testing laboratories performing conformity assessment and type testing.
- Certification bodies and notified bodies assessing compliance with the ISO 12402 series for market approval.
- Procurement officers and specifiers who need robust test-based acceptance criteria for PFD purchases.
- Regulators and safety managers developing workplace or maritime safety requirements.
Using ISO 12402-9 helps ensure PFDs are evaluated consistently for safety, durability and human performance, improving user protection in water-related activities.
