Analytical colorimetry - Part 2: Saunderson correction, solutions of the Kubelka-Munk equation, tinting strength, depth of shade, hiding power (ISO 18314-2:2023)
This document 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 based on different criteria such as the depth of shade. Finally, methods for determining the hiding power are provided.
The procedures for preparing the samples for these measurements are not part of this document. They are agreed between the contracting parties or are described in other national or international standards.
Analytische Farbmessung - Teil 2: Saunderson‑Korrektur, Lösungen der Kubelka‑Munk‑Gleichung, Farbstärke, Farbtiefe und Deckvermögen (ISO 18314-2:2023)
Dieses Dokument legt die Saunderson Korrektur für unterschiedliche Messgeometrien sowie die Lösungen der Kubelka Munk Gleichung für deckende und durchsichtige Schichten fest. Es legt außerdem Verfahren zur Berechnung der Farbstärke, einschließlich des Restfarbabstandes, mit unterschiedlichen Kriterien, die auf der Farbtiefe beruhen, fest. Schließlich werden Verfahren zur Bestimmung des Deckvermögens zur Verfügung gestellt.
Die Durchführungen der Probenherstellung für diese Messungen sind nicht Bestandteil dieses Dokuments. Diese werden zwischen den Vertragspartnern vereinbart oder sind in anderen nationalen oder internationalen Normen beschrieben.
Analyse colorimétrique - Partie 2: Correction de Saunderson, solutions de l'équation de Kubelka-Munk, pouvoir colorant, profondeur de teinte, pouvoir masquant (ISO 18314-2:2023)
Le présent document spécifie la correction de Saunderson pour différentes géométries de mesure et les solutions de l’équation de Kubelka-Munk pour les couches masquantes et transparentes. Il spécifie également les méthodes de calcul du pouvoir colorant et de l’écart de couleur résiduel basées sur différents critères, tels que la profondeur de teinte. Enfin, des méthodes sont fournies pour déterminer le pouvoir masquant.
Les méthodes de préparation des échantillons destinés à ces mesurages ne sont pas couvertes par le présent document. Elles sont fixées par accord entre les parties contractantes ou sont décrites dans d’autres normes nationales ou internationales.
Analizna kolorimetrija - 2. del: Saundersonova korekcija, rešitve Kubelka-Munkove enačbe, barvna jakost, globina barve in kritnost (ISO 18314-2:2023)
Ta dokument določa Saundersonovo korekturo za različne merilne geometrije in rešitve Kubelka-Munkove enačbe za prikrivajoče ter prosojne plasti. Določa tudi metode za izračune barvne jakosti, vključno z razliko ostankov barv na podlagi različnih kriterijev, kot je globina barve. Podane so tudi metode za določanje kritnosti.
Postopki za pripravo vzorcev za te meritve niso del tega dela dokumenta. O njih se dogovorijo pogodbenice ali pa so opisani v drugih nacionalnih ali mednarodnih standardih.

Foreword
ISO (the International Organization for Standardization) is a worldwide federation of national standards
bodies (ISO member bodies). The work of preparing International Standards is normally carried out
through ISO technical committees. Each member body interested in a subject for which a technical
committee has been established has the right to be represented on that committee. International
organizations, governmental and non-governmental, in liaison with ISO, also take part in the work.
ISO collaborates closely with the International Electrotechnical Commission (IEC) on all matters of
electrotechnical standardization.
The procedures used to develop this document and those intended for its further maintenance are
described in the ISO/IEC Directives, Part 1. In particular, the different approval criteria needed for the
different types of ISO documents should be noted. This document was drafted in accordance with the
editorial rules of the ISO/IEC Directives, Part 2 (see www.iso.org/directives).
Attention is drawn to the possibility that some of the elements of this document may be the subject of
patent rights. ISO shall not be held responsible for identifying any or all such patent rights. Details of
any patent rights identified during the development of the document will be in the Introduction and/or
on the ISO list of patent declarations received (see www.iso.org/patents).
Any trade name used in this document is information given for the convenience of users and does not
constitute an endorsement.
