TS EN ISO 24808/A11

TS EN ISO 24808/A11. OFFICIAL SCOPE IS UNAVAILABLE. This document belongs to the technical field of recreational diving services and addresses the training of rebreather instructors. In general terms, rebreather systems recycle part of the breathing gas during a dive, which makes their operating principles different from open-circuit equipment. Because of that difference, instructor training is not only about diving skills, but also about understanding the system’s behaviour, operating limits, and the teaching responsibilities involved in passing that knowledge on to others.

Technical context of rebreather instructor training

From a general technical perspective, rebreather instruction involves gas management, breathing-loop behaviour, carbon dioxide accumulation risk, control of oxygen exposure, and correct communication of equipment procedures. The instructor role is broader than personal diving competence: it also requires the ability to teach complex system use, recognise operational risks, and guide students through disciplined procedures. Standards in this area typically aim to align subject knowledge, practical diving experience, risk awareness, and instructional capability.

What the A11 designation means

The A11 designation indicates that this is an amendment-type document linked to the base standard. For that reason, the listing should be understood as part of the wider standard family rather than as a standalone description of every core requirement. It serves as a technical reference for training organisations, instructor candidates, and diving service providers who need the current TSE/European adaptation for rebreather instructor training.
