ISO 12402-7:2020

Overview

ISO 12402-7:2020 - "Personal flotation devices - Part 7: Materials and components - Safety requirements and test methods" sets the minimum safety, construction and test requirements for materials and components used in personal flotation devices (PFDs) and lifejackets. It is part of the ISO 12402 series addressing PFD performance and is intended for PFDs used for work and leisure in or near water (excluding SOLAS-regulated seagoing ship lifejackets).

Key topics and technical requirements

This standard specifies sampling, pass/fail criteria, conditioning and specific test methods for the following materials and components:

• Sewing thread - construction, loop breaking strength and performance criteria.
• Fabric - durability, colour (chromaticity and luminance for fluorescent/non‑fluorescent lifejacket materials), and performance tests.
• Structural webbing, tie tape and lacing - construction, torsional stiffness and strength requirements.
• Structural zippers and hardware - construction and performance criteria for closures, adjusters, lacing closures, multi‑eyelet guides.
• Foam flotation material - density, compressibility and durability tests, including knitted fabric lamination to foam.
• Inflation chamber and polymeric coatings - materials, seam integrity and performance tests.
• Inflation systems (hybrid and solely inflatable lifejackets) - construction, operability and discharge tests for automatic, manual and oral systems; humid atmosphere and durability tests; operability and over‑pressure relief valve tests; human‑subject performance tests where applicable.
• Gas‑filled cylinders - construction, pressure tests, acceptance criteria and marking requirements.

The document also includes normative references, terms and definitions, and informative annexes (e.g., mildew resistance, abrasion tests, example design drawing).

Notable updates in the 2020 edition include revised temperature cycling, modified compliance criteria for fabrics, webbings and hardware, and updated chromaticity/luminance requirements for lifejacket colours.

Practical applications and users

ISO 12402-7:2020 is used by:

• PFD and lifejacket manufacturers for material selection, product design and compliance testing.
• Test laboratories and conformity assessment bodies to perform standardized material and component tests.
• Regulatory authorities, procurement teams and specification writers who require verified material performance for safety equipment.
• Design engineers and product development teams integrating inflatable systems, foam cores, closures and fittings into PFDs.

Applying this standard helps ensure consistent safety performance, durability and interchangeability of PFD materials across recreational and occupational markets.
