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.

assessment, as well as information about ISO’s adherence to the WTO principles in the Technical Barriers

ISO 10545-16 was prepared by Technical Committee ISO/TC 189, Ceramic Tiles,
This third edition cancels and replaces the second edition (ISO 10545-16:2010), which has been
technically revised.
ISO 10545 consists of the following parts, under the general title Ceramic tiles —:

DRAFT INTERNATIONAL STANDARD ISO/DIS 10545-16:2015(E)
Ceramic tiles —
Part 16:
Determination of small colour differences and light
reflectance values
1 Scope
This part of ISO 10545 describes methods for utilizing colour measuring instruments:
— for quantifying the small colour differences between plain coloured ceramic tiles, which are designed
to be of uniform and consistent colour. It permits the specification of a maximum acceptable value
which depends only on the closeness of match and not on the nature of the colour difference;
NOTE 1 Colour variations produced for artistic purposes are not covered in this part of ISO 10545.
NOTE 2 This test should only be used when small colour differences between plain coloured tiles are important
in a specification or by agreement.
— for determining the Light Reflectance Value (LRV) of ceramic tiles. The method of test is applicable
to tiles that have multi-coloured surfaces including those that cause extreme angular dependences
of reflected light and those that have a surface texture of < 2 mm.
2 Normative references
The following documents contain provisions which, through reference in this text, constitute provisions
of this part of ISO 10545. At the time of publication, the editions indicated were valid. All standards
are subject to revision, and parties to agreements based on this part of ISO 10545 are encouraged
to investigate the possibility of applying the most recent editions of the standards indicated below.
Members of IEC and ISO maintain registers of currently valid International Standards.

3 Terms and definitions
For the purposes of this part of ISO 10545, the following definitions apply.
3.1
Light Reflectance Value (LRV)
proportion of visible light reflected by a surface, weighted for the sensitivity to light of the human eye
Note 1 to entry: This is equivalent to CIE Tristimulus Y10 when viewed under Illuminant D65 and when measured
with the appropriate specimen and measurement geometry. Further details of the CIE Tristimulus values are
given in CIE 15:2004 and further details of the measurement of reflection are given in CIE 130:1998.
