日期:2012-02-08 11:07
t measure of release rate when very rapid or immediate flame involvement of the specimen surface occurs. However, piloted, point ignition allows release-rate information to be obtained at external heat flux from zero up to that required for satisfactory gas-phase ignition, usually over 20 kW/m2 external exposure. No correlation between the two modes of piloted ignition has been established.
Release rates depend on many factors, some of which cannot be controlled. It is possible that samples that
