Description / Abstract:
This International Standard specifies a procedure for sampling
of rosin and rosin derivatives from
— drums,
— the molten/liquid form,
— flakes, pellets or pastilles
and preparation of the samples for colour measurement. The
method to be used for the colour measurement is specified in other
standards. The colour of the rosin can be measured with neat rosin
or rosin in solution.
The two most commonly used colour-measurement methods are those
based on the USDA1) scale and the Gardner colour scale.
Annex A provides information on the correlation between these two
scales.
