摘要: Tests have been carried out on various extinguishing agents using a tubular propane burner. The Rate of Heat Release (RHR) was measured oxygen calorimetry. Thermal decomposition products were identified and quantified wet chemistry ion chromatography. Some found to increase the RHR. In addition generation fluorinated higher for replacement chemicals, amount thermal be linearly related time mass burning rate. flammability limits mixtures agent with air determined in explosion chambers volumes 8, 13 784 liters sparks 0.7-150 Joule across 4-5 mm electrode gap. results indicate that combination relatively high spark energy small volume 1 psi combustion criterion overestimates inerting concentration needed room protection.
