Paper and board - Measurement of specular gloss - Part 1: 75 degree gloss with a converging beam, TAPPI method (ISO 8254-1:2009)
ISO 8254-1:2009 specifies a method for measuring the specular gloss of paper at an angle of 75° to the normal to the paper surface. Although its chief application is to coated papers, it may also be used for glossy uncoated papers such as supercalendered papers.
Papier und Pappe - Bestimmung des Spiegelglanzes - Teil 1: Messung mit einem konvergierenden Strahl bei 75°, TAPPI-Verfahren (ISO 8254-1:2009)
Dieser Teil der ISO 8254 legt ein Verfahren zur Bestimmung des Spiegelglanzes von Papier bei einem Einfallwinkel von 75, bezogen auf die Normale zur Papieroberfläche, fest. Obwohl die Anwendung dieses Verfahrens hauptsächlich für gestrichene Papiere bestimmt ist, darf es auch für glänzende ungestrichene Papiere, wie hochsatinierte Papiere, verwendet werden.
ANMERKUNG 1 Dieses Verfahren bietet keine Bewertung der Qualität der Bildreflexion und sollte nicht für gussgestrichene, lackierte, hochglänzende oder gewachste Papiere sowie hochglänzende Druckfarbenschichten verwendet werden. Für diese Zwecke werden Messungen bei anderen Einfallwinkeln, z. B. 20, bevorzugt, obwohl das vorliegende Verfahren zur Glanzmessung der meisten anderen Druckfarbenschichten auf Papier oder Karton geeignet ist. Unterschiede in der Farbe und im diffusen Streuverhalten dieser Druckfarbenschichten haben eine unbedeutende Wirkung auf den nach diesem Teil der ISO 8254 bestimmten Glanz. Zum Beispiel ergeben Messungen auf weißen und schwarzen Oberflächen, die im Übrigen identisch sind, bei einer weißen Oberflächen einen Wert, der weniger als eine Glanzeinheit höher als der bei einer schwarzen Oberfläche ist.
ANMERKUNG 2 Die in ISO 2813, Paints and varnishes — Determination of specular gloss of non metallic paint film at 20, 60 and 85, festgelegten Verfahren können auf gewisse Papierarten angewandt werden.

L'ISO 8254-1:2009 spécifie une méthode de mesurage du brillant spéculaire du papier à un angle de 75°de la normale de la surface du papier. Bien que son domaine d'application principal soit celui des papiers couchés, elle peut aussi être utilisée pour les papiers brillants non couchés, par exemple des papiers supercalandrés.

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.
International Standards are drafted in accordance with the rules given in the ISO/IEC Directives, Part 2.
The main task of technical committees is to prepare International Standards. Draft International Standards
adopted by the technical committees are circulated to the member bodies for voting. Publication as an
International Standard requires approval by at least 75 % of the member bodies casting a vote.
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.
ISO 8254-1 was prepared by Technical Committee ISO/TC 6, Paper, board and pulps.
This second edition cancels and replaces the first edition (ISO 8254-1:1999). It has been technically revised,
in part to harmonize the wavelength specified in 5.2.1 with that specified in ISO 8254-2:2003 and
ISO 8254-3:2004. The reference wavelength defining the high-gloss reference standard has been changed
from 589,26 nm (sodium D line) to 587,56 nm (helium d line), but this change has a negligible effect on the
measured specular gloss value.
ISO 8254 consists of the following parts, under the general title Paper and board — Determination of specular
gloss:
⎯ Part 1: 75° gloss with a converging beam, TAPPI method
⎯ Part 2: 75° gloss with a parallel beam, DIN method
⎯ Part 3: 20° gloss with a converging beam, TAPPI method

ISO 8254-1:2009(E)
Introduction
This part of ISO 8254 deals with the assessment of the “gloss” of a paper or board surface by determining an
optical property called the “specular gloss” which is here defined in terms of a measurement made at 75°
using a converging beam geometry, commonly known as the TAPPI method and described in
[1]
TAPPI 480 om-92 . Other parts of this International Standard deal with measurements made at 75° using a
collimated beam geometry known as the DIN method, and with measurements made at 20°. Gloss results are
greatly dependent on the angle of measurement and on the type of incident beam (converging or collimated),
so conditions of measurement shall be carefully defined.
The definition of gloss (3.1) relates to a mode of visual perception, whereas the method described uses a
physical measurement of mixed regular and diffuse reflection. The exact correlation between the visual
perception and the scale established by the physical measurement is not known. However, this physical gloss
scale has proved to be useful for a number of technical applications and consequently its standardization is
justified.
INTERNATIONAL STANDARD ISO 8254-1:2009(E)
Paper and board — Measurement of specular gloss —
Part 1:
75° gloss with a converging beam, TAPPI method
1 Scope
This part of ISO 8254 specifies a method for measuring the specular gloss of paper at an angle of 75° to the
normal to the paper surface. Although its chief application is to coated papers, it may also be used for glossy
uncoated papers such as supercalendered papers.
NOTE 1 This method does not provide an assessment of image-reflecting quality and should not be used for cast-
coated, lacquered, highly varnished or waxed papers or for high-gloss ink films. For these purposes, measurements at
other angles, for example 20°, are preferred, although the present method has been shown to be suitable for gloss
measurements of most other ink films on paper or paperboard. Differences in the colour and the diffuse reflectances of
these ink films have a negligible effect on gloss measured according to this part of ISO 8254. For example, measurements
on white and black surfaces which are otherwise identical give a value for the white surface that is less than one gloss unit
higher than the value for the black surface.
NOTE 2 The methods specified in ISO 2813, Paints and varnishes — Determination of specular gloss of non-metallic
paint films at 20°, 60° and 85°, may be applicable to certain grades of paper.
