Test Method 170-2011
Propensity of Powder Dyes: Evaluation of
in 1987 by AATCC Committee RA87
Purpose and Scope
This test method provides a standard method for the evaluation of dusting properties
of powder dyes.
1.2 The method of assessment permits the assignment
of a numerical rating describing the degree of dusting; or, conversely, the degree
of non-dusting of powder dyes
1.3 This test method is not intended for
a quantitative determination of dusting. Water soluble dyes may give an
inferior rating than an equal amount of dusting caused by disperse dyes.
Further studies indicated that not all factors; i.e., humidity, are fully controlled.
Also the method does not distinguish between slow and fast settling dust.
