Описание (английский):

ISO 13293:2012 specifies requirements for gas blender training programmes and the competencies required of an individual in order to obtain a gas blender certificate from a training organization, attesting that he/she has met or exceeded the requirements specified in ISO 13293:2012. ISO 13293:2012 specifies two levels of gas blender qualification, as follows: Level 1 gas blender; Level 2 gas blender. ISO 13293:2012 recognizes that a training programme can be organized and delivered in a modular way.

Overview

ISO 13293:2012 - "Recreational diving services - Requirements for gas blender training programmes" defines minimum requirements for training, assessment and certification of gas blenders who prepare breathing gases for recreational diving. The standard establishes two qualification levels (Level 1 and Level 2), recognizes modular programme delivery, and sets competency, instructor and qualification criteria used by training organisations and filling-station operators.

Key topics and technical requirements

Two qualification levels

Level 1 gas blender: authorised to blend enriched air nitrox (EAN).
Level 2 gas blender: authorised to blend and supply broader mixes including helium-based mixtures (trimix, heliox).

Theoretical knowledge required for each level:

Gas properties (oxygen, nitrogen, helium, argon, air, EAN)
Gas blending and delivery methods: membrane/molecular sieve (nitrogen reduction), continuous blending, partial-pressure blending, gravimetric (by weight), premixed gases, booster pumps
Oxygen hazards and oxygen service principles: oxygen-clean, oxygen-compatible design, contamination avoidance, fire triangle risks
Cylinder marking, valves, adapters, permissible regional colour coding and regulations
Gas flow rates, analysers, record keeping, and blending calculations (manual, tables or software)

Practical skills

Calibrate and use oxygen (and for Level 2, helium) analysers
Fill cylinders to specified tolerances: ±1% oxygen for EAN; Level 2 helium content within ±3%
Complete cylinder labels/tags and filling-station logs

Instructors and assessment

Instructors must be certified to the level they teach and have practical mixing experience; Level 2 instructors can teach both levels
Students must pass a knowledge exam and demonstrate practical skills; minimum age 18
Training records and examination logs are required

Practical applications

Ensures safe, standardised training for personnel who blend and supply diving gases at:

Dive centres and filling stations
Scuba training agencies and federations
Liveaboard operators and resort dive shops

Improves safety and consistency in gas analysis, cylinder handling, and filling procedures-reducing oxygen fire/explosion risks and human error in gas mixes.
