8.2.3.2 Gas detection / off-gas detection


Gassing from BESS potentially resulting as a consequence from type tests shall be qualified in terms of flammability characteristics and related risks of explosive atmosphere by appropriate technical means.

​Note: In addition, for BESS that may experience potential for thermal runaway according to Annex B, a large scale fire test that includes monitoring for flammable gas emissions may need to be conducted. Data on the type and quantity of flammable gas emissions obtained during testing can assist in determining suitable deflagration venting to prevent explosion hazards in the event of a fire from the BESS. See Annex C for details regarding large scale fire testing.

Upon installation, any functions of detection systems, audible alerts and visual signals for reporting an incident of flammable gas shall be tested in accordance with appropriate standards, manufacturer instructions and local regulations to confirm that their functions automatically operate when the concentrations of flammable gas exceeds the limit which is indicated by manufacturer. Their functions shall operate as designed. The type test for individual components of detection systems, audible alerts and visual signals shall be done.

 

The FAT or SAT for the BESS with the combination of detection systems, audible alerts and visual signals shall also be done with

suitable simulated signals for events to be detected. Refer to IEC 60079-29 series for guidance on flammable gas detectors.
