Hi Techies,
Picking-up on a Technet string which talks about VOCs, I thought it
appropriate to post the following for consideration.
When talking VOCs, it is really important to respect the way in which rules
are interpreted in our respective countries. In the USA you have a list of
solvents that enjoy "exempt" status from VOC legislation. As I understand it,
this means that you can avoid paying tax if you use "exempt" solvents.
Again, as Brian Ellis stated, unfortunately (or fortunately depending upon
which side of the tracks you are on) in Europe a VOC is any organic (carbon
based) material having a vapour pressure above 0.01kPa. It is a mandate in
Europe (EC Directive) to reduce VOC emissions but we have no policemen so it is
largely ignored by all except the large multi-nationals who are ISO14000
qualified. Frankly I seriously wonder how many there are out there who even
understand the difference including the interpretation of the directive.
I do not seek comments on the rights and wrongs of each approach, only to
state the different ways in which legislation is being imposed.
I can say with absolute certainty that VOC exempt solvents such
as nButylacetate may be OK in the USA but NOT here in Europe - it is a VOC
PERIOD!
Even whisky and bourbon, vodka and gin are VOCs and I
say "NO TO PROHIBITION!"
