They arefrequently cylindrical in shape but may also assume a twisted shape (see Annex C).NOTE 2 Porosity may vary in size from the submicroscopic, invisible using a light microscope, to the microscopic,visible from × 10 to × 1 000, to the macroscopic, visible to the naked eye.NOTE 3 Porosity may be visibly indicated by discolouration of the coated surface.NOTE 4 Porosity in a coating is not always detrimental. In microdiscontinuous chromium, for example, porosity ormicrocracking is beneficial and tests are conducted to indicate the pores.NOTE 5 Results obtained from porosity tests, expressed in terms such as pores per square centimeter, are relativevalues associated with the specific test method used and the magnification used during examination.
