Metoda të përgjithshme të analizës për pigmente dhe shpërndarës - Pjesa 17: Krahasimi i fuqisë ndriçuese të pigmenteve të bardha (ISO 787-17: 2002)

General methods of test for pigments and extenders - Part 17: Comparison of lightening power of white pigments (ISO 787-17:2002)

Scope

This part of ISO 787 specifies a general method of test for comparing the lightening (reducing) power of a white pigment with the lightening power of an agreed sample of the same type.
Two procedures (A and B) are described. Procedure A is quicker than procedure B and is suitable for testing one sample of pigment; procedure B is better for testing several samples, and especially if a pigment of unknown lightening power is being tested.
