||First Remote Field Testing Standard for Heat Exchangers Establishes
Excruciating attention to detail by Canadians and Americans
involved in remote field testing (RFT) has led to the release
of a long-needed standard for the nondestructive testing (NDT)
of heat exchangers used in the oil and gas, power, and petrochemical
industries. Now available from ASTM Committee E07 on Nondestructive Testing, ASTM E 2096, Standard Practice for In Situ Examination of Ferromagnetic Heat
Exchanger Tubes Using Remote Field Testing, offers a uniform communication
reference when hunting for damaged tubes.
It was either create a standard, or watch a valuable technology
get abad name, said David Mackintosh, P.Eng., research engineer,
Russell NDE Systems Inc., Edmonton, Canada, who approached ASTM in response to an industry call for standardization.
ASTM provided the ideal forum for us to get the work done. The
new standard will help raise the quality of RFT continent-wide.
It also serves to protect users, especially if they are unfamiliar
with RFT. Well be seeing fewer leaking tubes and happier customers.
Without a standard, plant operators in heavy industries cant
reference a widely-accepted document when discussing NDT of carbon
steel tubing in their heat exchangers. Misunderstandings can lead
to plant down time and potentially explosive situations. Before
the standard was available, experience or training qualifications
for NDT personnel had not been established, and a basic language
didnt exist for discussion of flaw detectability or permeability
To remedy this problem, approximately 55 Canadian and American
RFT practitioners, consumers, researchers, manufacturers, and
consultants collaborated on a task group of ASTM Subcommittee E07.07 on
Electromagnetic Method. The task group was initiated by Mackintosh
at a symposium that was the culmination of a series of international
conferences. The completion of ASTM Standard E 2096 was also supported
by a comprehensive survey of RFT capabilities by the task group
chair, Larry Cagle, consultant, EPRI NDE Center, Charlotte, NC.

Fla. For meeting or membership details, contact Director George Luciw, ASTM (610/832-9710). //
