标准范围
This International Standard deals with quantitative evaluation of scratch–induced damage and scratchvisibility in polymers.This International Standard specifies two methods to assess scratch damage and scratch visibilityexpressed 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 aconstant 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 isrepresented by scratch visibility index (SVI).The methods are suitable for use with coated and uncoated thermoplastic and thermosetting mouldingmaterials.The methods specify the preferred dimensions of testing specimens and the preferred scratch-tipgeometry.
