Description / Abstract:
This International Standard deals with quantitative evaluation
of scratch–induced damage and scratch visibility in polymers.
This International Standard specifies two methods to assess
scratch damage and scratch visibility expressed by three colour
coordinates of a 3-D colour model.
Method A uses a scratch tip capable of area-contact or
line-contact with material surfaces under a constant load
condition. It is represented by scratch damage index (SDI). Method
B uses a scratch tip capable of line-contact under a linearly
increasing load condition. It is represented by scratch visibility
index (SVI).
The methods are suitable for use with coated and uncoated
thermoplastic and thermosetting moulding materials.
The methods specify the preferred dimensions of testing
specimens and the preferred scratch-tip geometry.
