Overview

EN ISO 13293:2012 - Recreational diving services: Requirements for gas blender training programmes specifies minimum requirements for training programmes and the competencies an individual must demonstrate to receive a gas blender certificate. The standard defines two qualification levels (Level 1 and Level 2), recognizes modular delivery of training, and focuses on safe production, analysis, handling and supply of breathing gas mixes for recreational diving.

Key Topics

• Qualification levels
  • Level 1 gas blender: authorized to blend enriched air nitrox (EAN).
  • Level 2 gas blender: authorized to blend and supply a broader range of gases (including helium-based mixes such as trimix/heliox where covered).
• Competencies and scope
  • Competence to blend gases, verify cylinder compatibility (working pressure, marking, test validity) and maintain records.
  • Clear exclusions: completion of EN ISO 13293:2012 does not qualify a person to advise divers on gas selection, set dive operational parameters (e.g., maximum operating depth or partial pressure limits), or perform oxygen cleaning and equipment servicing.
• Theoretical and practical content
  • Gas blending and delivery methods, composition of gases and gas blends, and considerations for elevated oxygen levels.
  • Oxygen compatibility and oxygen-clean concepts; cylinder marking and handling; gas analysis, record keeping and gas blending calculations.
  • Practical skills assessments and instructor competence requirements.
• Quality and safety
  • Emphasis on following accepted safety protocols and standards when producing and supplying breathing gases.

Applications

• Target users and beneficiaries:
  • Dive training organizations and scuba diving federations implementing or auditing gas blender training programmes.
  • Dive operators and recreational diving service providers who need trained personnel to prepare and supply breathing gases safely.
  • Regulatory bodies and quality managers establishing minimum competency criteria for gas blending in recreational diving.
• Practical value:
  • Helps ensure consistent, traceable gas blending practices, reducing risk from incorrect mixes or contaminated cylinders.
  • Supports modular training approaches, enabling organisations to tailor programmes for gas blender training, upskilling from Level 1 to Level 2, or integrating with broader instructor training.

Related Standards

• ISO 11107:2009 - Requirements for enriched air nitrox (EAN) training programmes
• ISO 24802-1 and ISO 24802-2 - Safety-related minimum requirements for recreational scuba instructor training (Levels 1 & 2)
• ISO 24803 - Requirements for recreational diving service providers

EN ISO 13293:2012 is a practical reference for safe gas blending in recreational diving and provides a harmonized basis for certificates, training curricula, and competency assessment.

Foreword
ISO (the International Organization for Standardization) is a worldwide federation of national standards bodies
(ISO member bodies). The work of preparing International Standards is normally carried out through ISO
technical committees. Each member body interested in a subject for which a technical committee has been
established has the right to be represented on that committee. International organizations, governmental and
non-governmental, in liaison with ISO, also take part in the work. ISO collaborates closely with the International
Electrotechnical Commission (IEC) on all matters of electrotechnical standardization.
International Standards are drafted in accordance with the rules given in the ISO/IEC Directives, Part 2.
The main task of technical committees is to prepare International Standards. Draft International Standards
adopted by the technical committees are circulated to the member bodies for voting. Publication as an
International Standard requires approval by at least 75 % of the member bodies casting a vote.
Attention is drawn to the possibility that some of the elements of this document may be the subject of patent
rights. ISO shall not be held responsible for identifying any or all such patent rights.
ISO 13293 was prepared by Technical Committee ISO/TC 228, Tourism and related services.
