Determination of the resistance to hydrocarbon pool fires of fire protection materials and systems f...
This document specifies a test method for determining the fire resistance of pressure vessels with a fire protection system when subjected to standard fire exposure conditions. It does not address vessels cooled by water deluge or water monitor. The test data thus obtained permits subsequent classification on the basis of the duration for which the performance of the pressure vessel under these…
Explosive atmospheres - Part 11: Equipment protection by intrinsic safety "i"
