However, remembering that this was published 1 year and 9 months before
the Montreal Protocol was signed, please read 16.1.2.7.2.

In those days, nearly everybody used CFC-113 blends and TMS was one of
the best of the azeotropes for defluxing. If anyone even thought any
different (especially for MIL apps), they would have the whole
establishment dropping down on them like a tonne of bricks (voice of
experience !!!), yet just five years later it was generally admitted
that it was not a good solvent for defluxing and that nearly any of the
non-ozone-depleting processes performed better. That is the price of
progress but illustrates that our industry is ultra-conservative to the
point of stifling progress, at times. Today, we pay too much lip-service
to standards, many of which were written based on data that is up to 50
years old and are totally irrelevant to today's technology - yet they
persist.

Best regards,

Brian
