SIST EN ISO 24804:2022/A11:2024 PDF

Overview

SIST EN ISO 24804:2022/A11:2024 is the latest amendment to the European standard that defines requirements for rebreather diver training programmes focused on no-decompression diving. Published by CEN (the European Committee for Standardization) in July 2024, this standard outlines the competencies necessary for recreational divers to safely conduct rebreather dives using nitrox breathing gas to a maximum depth of 30 meters without mandatory decompression stops. It complements the general recreational diving service requirements detailed in ISO 24803 and provides specific evaluation criteria to ensure consistent and high-quality training delivery.

Key Topics

• Rebreather Diver Training Requirements Sets out mandatory competencies for divers using rebreather systems, emphasizing safe operation during no-decompression dives.

• No-Decompression Diving with Nitrox Focuses on dives not requiring decompression stops, limiting operations to a maximum depth of 30 meters to enhance safety and accessibility.

• Competency Evaluation Criteria Specifies how diver skills and knowledge must be assessed to confirm proficiency in rebreather diving techniques.

• Training Programme Conditions Details the environmental, instructional, and administrative conditions under which training must be delivered to meet international and European standards.

• Alignment with ISO 24803 Builds upon the foundational recreational diving services framework to provide specialized guidance for rebreather diver education.

• National Regulatory Considerations Includes provisions on how national regulations, such as those in France, may influence the applicability of certain requirements.

Applications

• Diving Schools and Training Centers Enables institutions to develop accredited rebreather diver training courses compliant with internationally recognized safety and competency benchmarks.

• Recreational Diving Operators Assists operators in ensuring their instructors and programmes meet standardized qualifications, improving diver safety and confidence.

• Certification Bodies Provides a framework to assess and certify divers specifically trained in no-decompression rebreather diving techniques.

• Equipment Manufacturers Supports manufacturers by establishing clear training needs associated with their rebreather products used within the specified parameters.

• Divers and Dive Professionals Offers divers clear guidance on training expectations and competency requirements when pursuing advanced diving skills with rebreathers.

• Regulatory Compliance Helps stakeholders align their practices with European and international safety standards to fulfill legal and insurance obligations.

Practical Value

By adhering to SIST EN ISO 24804:2022/A11:2024, diving service providers can:

• Ensure comprehensive and standardized training for rebreather divers focusing on no-decompression limits.
• Enhance diver safety through rigorous competency assessments and consistent training delivery.
• Facilitate cross-border recognition of diver qualifications across CEN member countries.
• Support the growing popularity of rebreather diving with structured, quality-controlled education programs.
• Align with best practices in recreational diving services, ensuring industry credibility and regulatory compliance.

This standard is an essential resource for all stakeholders involved in recreational rebreather diving, providing clarity and structure to training protocols that keep divers safe while exploring underwater environments.
