Overview
SIST EN ISO 12402-7:2020 (ISO 12402-7:2020) defines the minimum safety requirements and test methods for materials and components used in personal flotation devices (PFDs) such as lifejackets and buoyancy aids. Adopted as an EN standard, it provides harmonized criteria for construction, materials performance, sampling, conditioning and pass/fail assessment to ensure PFD durability, reliability and user safety.
Key topics and technical requirements
The standard covers material types, component construction and a comprehensive set of test methods. Major technical topics include:
- General principles, sampling and pass/fail criteria - procedures for selecting and conditioning specimens and reporting units of measurement.
- Sewing thread and seams - construction and loop-breaking strength performance requirements.
- Fabrics and colourfastness - fabric performance, exposure and colour durability tests.
- Structural webbing, tie tape and lacing - torsional stiffness, construction and strength testing for load-bearing components.
- Zippers and hardware - construction, functional and strength tests for structural zippers, webbing closures, adjusters and lacing closures.
- Foam flotation materials - foam type, performance, laminated knitted fabric tests and ageing behaviour.
- Inflation systems and inflation chamber materials - construction, operability, humid-atmosphere, durability, over‑pressure relief and human-subject performance tests for hybrid and inflatable lifejackets.
- Polymeric foam coatings and window materials - construction and performance testing for coatings used on flotation components.
- Gas-filled cylinders - construction, acceptance testing and marking requirements for gas cylinders used in automatic/manual inflation systems.
- Informative annexes - mildew resistance (soil burial), abrasion resistance (Wyzenbeek oscillatory method) and example design drawings.
Practical applications and users
This standard is essential for:
- PFD manufacturers and designers - to select compliant fabrics, foams, webbing and inflator components and to validate product durability and safety.
- Test laboratories and quality control - to perform standardized sampling, conditioning and pass/fail testing for certification and batch verification.
- Regulators and certification bodies - to assess conformity of personal flotation devices with European and international requirements.
- Procurement and fleet managers - to specify PFD material and component requirements for commercial, recreational and occupational safety programs.
