A simp le and easy2to2use HFRR gaso line test m ethod has been successfully developed by (i) redesigning the fuel bath recip rocating ball ho lder system to so lve the high vo latility p roblem of gaso line in HFRR tests, (ii) enclo sing HR FF in a sealable perspex box w ith a ho le fitted w ith a ground perspex p lug fo r convenient hum idity contro l, ( iii) using w ater vapour p ressure (WV P) instead of relative hum idity (RH ) as an index of hum idity to co rrectly reflect the true w ater content in the air, and (iv) designing a very strict cleaning p rocedure so as to avo id cro ss contam ination and guarantee good repeatability. It has been found that HFRR test m ethod has good repeatability and differentiating ability. Key words: fuel;
