Description / Abstract:
Introduction
Note: Nothing in this standard supercedes
applicable laws and regulations.
Note: In the event of conflict between the
English and domestic language, the English language shall take
precedence.
Purpose. This procedure attempts to quantify
the blush resistance of plastic materials (primarily used with
polypropylene and related color concentrates). It establishes a
Stress Evaluation Test (SET) number which can be used to predict
blushing due to changes in pigment concentration.
Applicability. This test is intended for
polyolefinic materials only.
