General Information

Overview
EN ISO 24805:2022/A11:2024 is a CEN amendment to the international standard for rebreather diver training within recreational diving services. It specifies the requirements and evaluation criteria for training programmes that develop the competencies needed to perform decompression diving using a rebreather to 40 m with nitrox or to 45 m with trimix, where dives require mandatory decompression stops. This amendment supplements the general recreational diving service requirements given in ISO 24803 and was approved by CEN in April 2024.
Key Topics
- Scope and limits: Training programme boundaries for rebreather dives - nitrox to 40 m, trimix to 45 m - with mandatory decompression procedures.
- Competency outcomes: Defined evaluation criteria to assess diver skills, knowledge and decision-making specific to rebreather decompression diving.
- Training programme requirements: Conditions under which training must be delivered (in addition to ISO 24803), including instructor qualifications, curriculum structure and safe training practices.
- Regulatory/adoption notes: Amendment A11 is intended for national adoption by CEN members; Annex B documents national deviations (e.g., France has a normative deviation restricting applicability).
- Normative references: Links to related standards required for application (ISO 11107, ISO 24801-2, ISO 24802-2, ISO 24803).
Applications
- Dive training organisations and recreational diving service providers implementing or updating rebreather diver courses to meet recognized European requirements.
- Instructor trainers and certification bodies designing assessment criteria and documenting competency standards for decompression rebreather training.
- Dive operators and centres that run advanced technical dives requiring trimix and structured decompression planning.
- Risk managers and quality assurance teams using the standard as a baseline for safe training delivery and course auditing.
Who should use this standard
- Rebreather instructor trainers and course developers
- Dive centres offering advanced rebreather/decompression courses
- Certification agencies and national standards bodies
- Dive safety officers and programme auditors
