ISO 15027-2:2026

Overview

ISO 15027-2:2026 - Immersion suits - Part 2: Safety and performance requirements for abandonment suits establishes comprehensive safety and performance requirements for abandonment suits and suit systems. This international standard is developed by ISO to ensure that individuals engaged in professional or leisure activities on or near water are adequately protected in emergency situations involving cold-water immersion. The main objective is to mitigate the effects of cold shock and delay the onset of hypothermia, offering users a greater chance of survival while awaiting rescue.

ISO 15027-2:2026 applies to both dry and wet abandonment suits but excludes constant wear suits, for which requirements are detailed in ISO 15027-1:2026. The document also covers accessories, personal flotation devices (PFDs), and outlines key criteria such as thermal protection, durability, conspicuity, and ergonomics.

Key Topics

• Thermal Protection: Suits are designed to insulate against cold-water immersion, minimizing cold shock and delaying hypothermia. Multiple performance levels are defined to address varying water temperatures and immersion durations.
• Suit Types: The standard applies to both wet and dry abandonment suits, ensuring protection across different suit designs and user needs.
• Safety and Ergonomics: Focus on suit systems that do not hinder movement, are comfortable, minimize snagging risks, and are compatible with rescue equipment or PFDs.
• Conspicuity: Abandonment suits must be highly visible (yellow to red range), utilize retro-reflective materials, and may include emergency-position-indicating lights to facilitate search and rescue.
• Accessories and Markings: Guidelines for essential accessories (e.g., whistles, buddy lines, lights), suit system components, clear marking, and user information.
• Material and Construction: Requirements for material innocuousness, durability, flame resistance, and resistance to water ingress and temperature extremes.
• Testing Protocols: Reference to standardized test methods (ISO 15027-3:2026) for verifying compliance, including thermal performance, buoyancy, and material quality.

Applications

ISO 15027-2:2026 is valuable across various marine safety applications and is especially relevant for:

• Commercial shipping and offshore operations: Ensuring crew members are equipped with suits that offer maximum protection during vessel abandonment in cold waters.
• Oil and gas platforms: Meeting regulatory requirements for personal safety during emergency evacuation from offshore installations.
• Search and rescue operations: Equipping rescue teams and evacuees with reliable immersion suits for prolonged survival in harsh maritime environments.
• Leisure boating and water sports: Providing recreational users with certified abandonment suits that enhance safety and visibility during emergencies.
• Harsh environmental conditions: Serving in regions where cold water poses a significant threat to survivors.

Compliance with ISO 15027-2:2026 not only enhances user safety but also supports organizational risk management, regulatory adherence, and operational continuity in maritime and offshore industries.

Related Standards

For a holistic approach to immersion and abandonment suit compliance, refer to the related ISO standards:

• ISO 15027-1:2026: Safety and performance requirements for constant wear suits.
• ISO 15027-3:2026: Test methods for immersion suits.
• ISO 12402 series: Performance and safety requirements for various personal flotation devices.
