PAINTS AND VARNISHES - RAPID-DEFORMATION (IMPACT RESISTANCE) TESTS - PART E3: FALLING-WEIGHT TEST, LARGE-AREA INDENTER (SECOND REVISION) (ISO 6272-1:2002, MOD)
This part of ISO 6272 describes a method for evaluating the resistance of a dry film of paint, varnish or related
product to cracking or peeling from a substrate when it is subjected to a deformation caused by a falling weight, with
a 20-mm-diameter spherical indenter, dropped under standard conditions.
NOTE The term “impact resistance” is included in the title of this part of ISO 6272, but one important characteristic of the
apparatus used is that it should produce rapid deformation rather than a true impact.
