EUROLAB, with its state-of-the-art accredited laboratories and expert team, provides precise and fast testing services within the scope of ISO 7491 testing. Color stability is an important property of dental products and it is desirable that International standards defining the properties of these products refer to the test methods described in this International standard.
This International standard specifies a method for determining the color fastness of dental products after exposure to light and water. Various dental product standards specify the method of sample preparation and conditioning as well as dimensions, as well as how to prepare a reference sample.
These standards should be used in conjunction with this International Standard.
Use three observers with normal color vision to visually compare the exposed and unexposed halves of each test piece for color differences. Normal color vision should be checked by a doctor or other suitably trained person. It is possible to use untinted corrective lenses.
