Max Levy Autograph, Inc. ISO 14997 PLUS Users Manual V1.1 - 5 - Note: According to ISO 10110-7 notation, any defect longer than 2mm is considered a long scratch. In classifying long scratches, only the width of the scratch is used. The sample scratch artifacts may be used to classify long scratches by only considering the width of the scratch.The scratch test can be combined with acoustic emission to give an indication of the onset and magnitude of failure. The hardness of the substrate material has a significant effect on the scratch resistance (cracking) of thin coatings during testing. [95] Commercial scratch test equipment with acoustic emission detection capability is available.
