IMO/LIFT Spread of Flame Apparatus
- This instrument uses a gas-fired radiant panel to assess surface flammability of marine surface finishes (ASTM E 1317, IMO) or to assess lateral ignition and spread of flame (LIFT, ASTM E 1321, ISO).
- The gas-fired radiant panel is controlled by a fully automatic spark ignition safety interlock system, for operator safety.
- A pilot burner is used to ignite the test specimen.
- Critical heat fluxes for ignition and flame spread are calculated, as required in specifications for the marine industry and for research.
- A stack is provided with thermocouples/thermopile as required by the standards.
- The complete test apparatus consists essentially of three main components: a radiant panel support framework, a specimen support framework (linked together to bring the test specimen into the required configuration with respect to the radiant panel) and the specimen holder.
- The apparatus is provided with all necessary controls, flux meter and specimen holder.
- The instrument is provided with software for obtaining all needed data, making the calculations and storing test data.
- All needed controls feed, via a data acquisition unit, into a personal computer.
- Smoke obscuration measurements are an optional add-on, via a smoke sampler in the exhaust duct. The option includes 0.3 and 0.8 neutral density filters for calibration.
- Other options include a pyrometer, with its digital display units and cables.
