The revision is to evaluate the improved Differential Pressure method and determine if the performance specifications in ASTM F2100 would need to change based on a potential new and improved method EN 14683 will be implementing in 2018. In addition, should an ASTM standard be created for Differential Pressure or should ASTM F2100 reference EN 14683 for the Differential Pressure method? To evaluate if ASTM F2299 critical parameters should be clarified or if the method should be replaced with an improved method. In both cases, the performance specifications need to be re-evaluated.
