Test Procedure by Referenced Test Procedure included User friendliness

Tested to IMO Resolution A.653(16)

Test Procedure based on ISO 5658-2:2006

Harmonization with ISO standard; same equipment for both tests

Pilot Flame: Acetylene flame, typically non-impinged;

Pilot Flame: impinged propane flame

-Harmonization with ISO standard; -Acetylene restrictions; -Reduce performance anomalies
