General methods of test for pigments and extenders - Comparison of lightening power of white pigments Ingestion-build-79769 in BS EN ISO 14698–1:2003What 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. 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
