sured. Therefore, the results are valid only for the fire test exposure conditions described in this procedure (see also 1.6).
1. Scope
1.1 This fire test response standard determines material properties related to piloted ignition of a vertically oriented sample under a constant and uniform heat flux and to lateral flame spread on a vertical surface due to an externally applied radiant-heat flux.
1.2 The results of this test method provide a minimum surface flux and temperature necessary for ig
