Content DescriptionISO 17541:2014 deals with quantitative evaluation of scratch-induced damage and scratch visibility in polymers. ISO 17541:2014 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. About ISOISO, the International Organization for Standardization, brings global experts together to agree on the best way of doing things – for anything from making a product to managing a process. As one of the oldest non-governmental international organizations, ISO has enabled trade and cooperation between people and companies all over the world since 1946. The International Standards published by ISO serve to make lives easier, safer and better. |
