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 3.
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.
International Standard ISO 8254-1 was prepared by Technical Committee ISO/TC 6, Paper, board and pulps,
working group WG 3, Optical properties.
ISO 8254 consists of the following parts, under the general title Paper and board — Measurement 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

Introduction
This part of ISO 8254 deals with the assessment of the specular gloss of paper and board at 75° using a converging
beam geometry commonly known as the TAPPI method and described in TAPPI 480 om-92 ([1] in the bibliography).
Subsequent parts of this International Standard will deal with measurements made at 75° using a collimated beam
geometry known as the DIN method (DIN 54502, [6] in the bibliography), and with measurements made at other
angles e.g. 20°.
The word "assessment" is used rather than "measurement" because the definition of gloss (3.1) relates to a scale 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.

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 International Standard. 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 2813:1978, Paints and varnishes — Measurement of specular gloss of non-metallic
paint film at 20°, 60° and 85°, may be applicable to certain grades of paper.
2 Normative references
The following normative documents contain provisions which, through reference in this text, constitute provisions of
this part of ISO 8254. For dated references, subsequent amendments to, or revisions of, any of these publications
do not apply. However, parties to agreements based on this part of ISO 8254 are encouraged to investigate the
possibility of applying the most recent editions of the normative documents indicated below. For undated
references, the latest edition of the normative document referred to applies. Members of ISO and IEC maintain
registers of currently valid International Standards.

3 Terms and definitions
For the purposes of this part of ISO 8254, the following terms and definitions apply.
3.1
gloss
mode of appearance by which reflected highlights of objects are perceived as superimposed on the surface due to
the directionally selective properties of that surface
[5]
[CIE Publication No. 17.4:1987, definition 845.04.73 ]
3.2
regular reflection; specular reflection
reflection in accordance with the laws of geometrical optics, without diffusion
[5]
[CIE Publication No. 17.4:1987, definition 845.04.45 ]

3.3
diffuse reflection
diffusion by reflection in which, on the macroscopic scale, there is no regular reflection
[5]
[CIE Publication No. 17.4:1987, definition 845.04.47 ]
3.4
specular gloss
ratio, expressed as a percentage, of the luminous flux reflected by the test surface into a specified aperture at the
angle of specular reflection to that from a standard specularly reflecting surface under the same conditions
4 Principle
Light incident on the test piece surface at an angle of 75° to the normal and reflected from the surface at an angle of
75° from the normal into a defined aperture is detected by a photodetector, the output of which is displayed on a
meter.
5 Apparatus
5.1 Gloss meter, having the general arrangement and relative dimensions of the principal parts described in
annex A. It consists of
a) a source of light,
b) a lens giving a converging beam of light incident to the test piece,
c) a suitable device such as a suction plate to hold the test piece flat if required, and
d) a photodetector to receive and measure certain of the rays reflected by the test piece.
These components are combined in a light-tight housing that is matt black inside and is structurally and optically
stable at the operating temperature.
5.2 Gloss standards, consisting of the following:
5.2.1 Primary gloss standard. The theoretical primary specular gloss standard is an ideal, completely reflecting
plane mirror having an assigned gloss value of 384,4 gloss units. A black glass which is flat and clean and has a
polished surface, having a refractive index of 1,540 at 589,26 nm, may be shown by the Fresnel equation ([3] in the
bibliography) to measure 100 gloss units on this scale.
5.2.2 High-gloss reference standard, consisting of a clean plaque of polished black glass for which the 75°
specular reflectance has been com
