Limiting Oxygen Concentration

Definition:

 

The limiting oxygen concentration is the maximum oxygen concentration in a mixture of an inflammable material with air and inert gas which does not explode in combination with arbitrary fuel concentrations. The limiting oxygen concentration is determinded under fixed test conditions.

 

Testing Method:

 

according to BG Chemie R 003 6/2000

(Further information see also Fire and Explosion Protection)

 

 

Safety-relevant meaning:

 

The explosion limits are relevant data for new material registrations. These datas combined with the limiting oxygen concentration are needed for the interpretation of the preventive measure "avoidance of combustible atmosphere".
