I am afraid that you have got things a little wrong.  PIKS (your
acronym is correct) is one of the three parts of IPI (Image Processing
and Interchange), the other two parts being "A Common Architecture for
Imaging" and the "Image Interchange Facility".  PIKS is directly
descended from ANSI committee work called PIK but is nothing like the
same.  PIK had many problems and arbitrary restrictions; the ISO
standard should not (if we have got it right).  PIK also had no
architectural material and no interchange capability, both of which
are in the developing ISO standard.

The draft international standard is being published as DIS12087 and
can be obtained from ISO central secretariat in Geneva.  It should
also be possible to buy it from national standards bodies: in the UK
(which is where the original poster resides), this is the BSI
distribution centre in Milton Keynes.  (But it is not available YET
and it won't be cheap when it is.)  Note that, since ISO own copyright
from the ISO stage, it is no longer possible to simply copy the
documents for someone else.

I hope this clears this up a little.
