BS 8618:2015

This standard BS 8618:2015 Granular carbon dioxide (CO₂) absorbent material for life support, diving, hyper- and hypobaric applications. Specification is classified in these ICS categories:

• 71.060.20 Oxides
• 71.100.20 Gases for industrial application

This British Standard gives requirements and test methods for granular and pelleted carbon dioxide absorbent materials.

NOTE For the purposes of this standard, the term “granular” includes both granular and pelleted material.

It is applicable to granular carbon dioxide absorbents intended for use in life-support applications including re-breathing apparatus on the surface and underwater, hyperbaric, and hypobaric applications.

It excludes granular and pelleted carbon dioxide absorbents intended for use in applications in medical anaesthesiology, materials that also generate oxygen, and monolithic pre-formed materials or those embedded within a polymer matrix.
