HIGH EXPANSION FOAM GLOSSARY, Drainage Time The time required for a specific percentage of foam solution to drain from the expanded foam. APSAD R12 A regulation which defines the minimum requirements for implementation commissioning and blanket and is often used as an indicator of how long the foam blanket will last For example 50 drainage time. maintenance of high expansion foam systems primarily used in France is the total time required for 50 of the volume of liquid consumed in generating the expanded foam to drain. from the foam, APSAD T12 The technical rules governing the coupling or joint testing of high expansion foam hardware and.

High Expansion Foam Protocol,STRENGTHS WEAKNESSES CONCLUSION.
EN1568 2 EN13565 1 Specifying the right high expansion foam system requires an understanding of the insights and limitations of. Strengths each test protocol as well as the intended application of the system The protocols discussed are designed. to evaluate foam system performance in different environments The IMO test protocols simulate machinery. Widely recognized foam and foam hardware standards in Europe spaces such as an engine room where the potential for pool fires three dimensional fires and pressure fires. Validates high expansion foam hardware through a mechanical testing program which typically includes but is greater and where the likelihood that the high expansion foam system will have to function using hot and. is not limited to assessment of heat resistance salt spray corrosion and mechanical vibration or smoky air is high Alternatively the T12 Technical Rules protocols measure effectiveness in flammable liquid. Weaknesses storage applications where the most likely hazard is a small pool fire In contrast to the application specific test. protocols of the IMO tests and the T12 Technical Rules the EN fire test protocol utilizes a laboratory scale fire. The test protocols do not validate the fire performance of the foam quality produced by full scale equipment test with limited correlation to real world applications for high expansion foam systems. Laboratory fire test protocols do not simulate a specific hazard. No validation of fire performance using inside air Selecting the best test protocol for your given application is a critical first step in selecting the equipment you. No validation of fire performance on polar solvents will rely on to help protect lives and property For assistance in identifying the most appropriate test protocol. and system requirements contact SKUM Technical Services info skum com. IMO MSC 1 Circ 1384, Validates the combination of full scale equipment and foam concentrate as a system. Validates performance of the high expansion foam system under conditions that mimic changes in inside. outside air temperatures, Fire test scenarios and test conditions are representative of real world hazards obstacles pool fires three. dimensional fires and pressure fires, Multiple test enclosure sizes provide reasonable scalability insight for the high expansion foam system tested. Validates high expansion foam hardware through a mechanical testing program which typically includes but. is not limited to assessment of heat resistance salt spray corrosion and mechanical vibration. Weaknesses,Polar solvent fire performance is not validated. APSAD T12 Technical Rules, Fire tests validate the combination of full scale equipment and foam concentrate as a system.
Fire tests offer the option to validate performance on both hydrocarbon and polar solvent fuels. Quantification of the Foam Destruction Rate allows for a method to account for the effect of the fire on the. fill rate of the system,Weaknesses, Requirements for the air temperature 5 C 25 C at the inlet to the high expansion foam generator eliminate. the possibility of testing under inside air conditions.
