Petroleum and Petrochemical Bulletin
IFIA Member company laboratories test products using methods issued and approved predominantly
by internationally recognised standards bodies (ASTM, EI, ISO). It frequently happens that, as
technologies improve, those bodies or organisations which publish test methods withdraw their
approval and methods become obsolete.
Manufacturers frequently stop producing and providing support for equipment specific to obsolete
Despite approval being withdrawn it sometimes happens that products are traded on the basis of
specifications offered or required by one or both parties which invoke an obsolete method.
It is the position of IFIA that when member companies are asked to use an obsolete test method the
member company may decline to accept the application of the method requested, and may suggest
an alternative test method to its principal, if one is available.
In cases where the principal requests the use of an obsolete or withdrawn method and the IFIA
Member company agrees to perform the test, IFIA wishes to make it clear that member companies do
not accept responsibility for the results obtained. Withdrawal of a method by the standards body
indicates problems with the method, frequently technical in nature. Therefore, while an IFIA member
can accept responsibility for correctly following the method, responsibility for validity or accuracy of the
results obtained cannot be accepted.
A recommended disclaimer for IFIA Members is given below.
IFIA recognises that there may be occasions when member companies are requested by their
principals to conduct analysis in accordance with methods which are not the latest published revision
of that method. However, the comments above apply only to obsolete or withdrawn methods.
