TS EN ISO 24807

TS EN ISO 24807 is the Turkish adoption of the standard that sets requirements for training programmes for rebreather divers. It addresses the competencies needed for dives to 100 m using a rebreather with a breathing mixture containing helium and with mandatory decompression stops, together with the criteria used to assess those competencies.

Training focus and technical meaning

The standard is centred on advanced training for planned decompression diving with rebreathers. Rebreather systems recycle part of the breathing gas, which can improve gas efficiency and reduce bubble release, but they also demand disciplined management of gas composition, carbon dioxide retention, oxygen control and emergency response. Helium is used in deep diving mixtures for well-established technical reasons related to gas density and narcosis management, so the training context extends beyond equipment handling into dive planning and operational judgement.

Assessment and training conditions

The document also specifies how these competencies are to be evaluated and the conditions under which training is delivered, in addition to the general requirements for recreational diving service provision. In practice, this creates a common technical framework for organisations and instructors delivering advanced rebreather diver training, with emphasis on consistent instruction, assessment and training conditions rather than on a single piece of equipment alone.
