Revision of E2307-20 Standard Test Method for Determining Fire Resistance of Perimeter Fire Barriers Using Intermediate-Scale, Multi-story Test Apparatus


The current time correction equation is erroneous in that it includes the lag correction of closed furnace probes as are used in ASTM E119, while the furnace probes used in the ISMA apparatus are open tip probes not subject to this lag constant. This open tip probe configuration is the same as is used in the test method UL 1709.
