Cracking

A break in a surface resulting in a visible separation of one part from another, extending through one or more layers.

Craquelure

COMMENT: COMMENT: Cracking is caused by the expansion and contraction of the layersaccompanied by a loss in elasticity. It can be the result of environmental fluctuations, vibrations, internal or external stresses or flaws in the surface. Cracking can be subdivided into: hairline cracks, microcracks (crazing), star cracks, aging cracks, radial or spiral cracks, craquelures, traction cracks, stretcher bar cracks, stress cracks or feather cracks.

Craquelure

Een breuk in het oppervlak met als resultaat een visuele scheiding, die door meerdere lagen heen gaat, van een verfdeel in twee delen.

Opmerking: Barsten in de verf zijn veroorzaakt door het uitzetten en krimpen van de lagen, gepaard gaand met een verlies van elasticiteit. Het kan de resultaat zijn van omgevingschommelingen, trillingen, interne of externe stress of fouten in het oppervlak. Barsten kunnen verder onderscheiden worden in: ???
