Over deze norm
This part of ISO 7203 specifies the essential properties and performance of liquid foam concentrates used to make low-expansion foams for the control, extinction and inhibition of reignition of fires of water-immiscible liquids. Minimum performance on certain test fires is specified. These foams are suitable for top application to fires of water-immiscible liquids. Those foams that comply with ISO 7203-3 are also suitable for top application to fires of water-miscible liquids. The foam concentrates can be suitable for use in non-aspirating sprayers or for subsurface application to liquid fires, but requirements specific to those applications are not included in this part of ISO 7203.
