ABSTRACT:
A method of and apparatus for testing the effectiveness against leakage of a seal in a gap between two surfaces which comprises positioning and securing an envelope to span the seal and gap and extend to the two surfaces to thereby form an enclosed cavity or space defined by the two surfaces, the seal therebetween and the envelope; feeding a gas stream into the cavity and removing the gas stream from the cavity; and analyzing the removed gas stream for any potential contaminant which leaks past the seal in the gap. The method is useful for testing the seal on a floating roof storage tank, such as for liquid petroleum products.
