General methods of test for pigments and extenders - Comparison of lightening power of white pigments Ingestion-build-81111 Both un-braced and braced systemsWhat is this standard about? 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.
