This International Standard specifies a method for
the determination of light absorption of cellulose
acetate, employing test specimens taken from two
mouldings which have been produced using different
periods of heating.
The aim is to provide quantitative measurements
which are compatible with visual judgements of
yellowness and lightness, and of changes in these
properties after moulding. The determinations are
carried out on cellulose acetate in plasticized form
rather than in solution, since a more reliable guide
is thereby obtained to the Performance of cellulose
acetate in plastics materials.

This method is intended for cellulose acetate having
an acetic acid yield of 54 % + 25 %. lt may also be
applicable to other transparent plastics which are
not strongly coloured and which tan be moulded
under the specified conditions.
