Overview
EN ISO 12402-5:2020 - "Personal flotation devices - Part 5: Buoyancy aids (level 50) - Safety requirements" is the CEN-endorsed adoption of ISO 12402-5:2020. The standard specifies safety, performance and marking requirements for buoyancy aids (performance level 50) intended for adults and children with body mass greater than 25 kg, used in sheltered waters. These buoyancy aids require active user participation and are intended where help and rescue are close at hand. One- and two-piece inherently buoyant flotation suits are designated as special application devices under ISO 12402-6:2020.
Key topics and technical requirements
The standard covers the full lifecycle of a buoyancy aid and includes:
- Classification and performance levels - defining the Level 50 category and its intended use.
- Materials and components - requirements for constituent materials, surface condition and durability (see Clause 5.1).
- Inflation and buoyancy - requirements for inflatable chambers, inherently buoyant material, total buoyancy and buoyancy retention (Clauses 5.3–5.3.5).
- Fit, donning and ride-up prevention - ergonomic and adjustment criteria to limit user impediment and ensure secure fit (Clause 5.6).
- Strength and in‑water performance - tests for structural strength and behavior in the water (Clauses 5.4–5.6).
- Marking and user information - mandatory marking, manufacturer instructions, rearming/repacking information, consumer point‑of‑sale data and colour-coding (Clauses 6–8).
- Safety interface with EU legislation - informative Annex ZA maps conformity to Regulation (EU) 2016/425 on personal protective equipment.
Practical applications and users
EN ISO 12402-5:2020 is used by:
- Manufacturers and product designers to design buoyancy aids that meet recognized safety and performance criteria.
- Testing laboratories and certification bodies for conformity assessment and type testing.
- Procurement managers and safety officers in marine leisure, watersports rental, training centers and sheltered‑waters operations specifying compliant PFDs.
- Retailers and consumers who need standardized marking and clear consumer information at point of sale.
- Regulators and compliance teams relying on the standard as a harmonized technical reference under EU PPE regulation.
Typical applications include recreational boating, kayaking, windsurfing, paddle sports and shoreline activities where self‑help and nearby rescue are expected.
