BS 8618:2015 Granular carbon dioxide (CO2) absorbent material for life support, diving, hyper- and hypobaric applications. Specification
What’s BS 8618?
The new BS 8618:2015 specifies minimum performance criteria for carbon dioxide absorbent materials for use in life-support applications. It aims to ensure the quality, performance and safety of carbon dioxide absorbent materials by standardizing methods for the assessment of granular and pelleted carbon dioxide absorbent material for use in life-support applications.
This standard should improve the safety of life-support systems.
Why is BS 8618 important?
Carbon dioxide absorbent materials remove the CO2 from the breathing gas in life support systems, and can ensure that exhaled CO2 is removed from closed-circuit systems. This is very important in life support systems that rely on the recirculation of breathing gas, both on surface and underwater.
Rebreather incidents involving the carbon dioxide absorbent systems are unfortunately still quite common, and they can result in blackout or death.
BS 8618 is the first standard to enable a defined performance and quality of the materials used in a rebreather system.
Who should use BS 8618?
This standard should be used by:
- Manufacturers of diving rebreathers
- Rebreather escape equipment manufactures
- Manufacturers of hyperbaric dive chambers
- Manufacturers of soda lime
- Diving industry
- Fire and rescue services
- Personal safety equipment manufacturers
