This part of DIN ISO 18314 specifies the Saunderson correction for different measurement geometries and the solutions of the Kubelka-Munk equation for hiding and transparent layers. It also specifies methods for the calculations of the tinting strength including the residual colour difference with different criteria and of the hiding power. The procedures for preparing the samples for these measurements are not part of this part of ISO 18314. They are agreed between the contracting parties or are described in other national or International Standards. The responsible German committee for this standard is NA 078-00-03 AA "Allgemeine Prüfverfahren für Farbmittel und Füllstoffe" ("General test methods for colorants and extenders") at DIN Standards Committee Pigments and Extenders (NPF).
