Tissue paper and tissue products - Part 7: Determination of optical properties - Measurement of brightness and colour with D65/10° (outdoor daylight) (ISO 12625-7:2021)
This document specifies testing procedures for the instrumental determination of brightness and colour of tissue paper and tissue products viewed under outdoor daylight conditions. It also gives specific instructions for the preparation of test pieces (single-ply, multi-ply products) and for the optical measurements of products, where special precautions can be necessary.
NOTE The properties called ISO brightness and colour with C/2° (indoor daylight) are measured with an instrument adjusted to a much lower UV content than that specified in this document. The measurements of ISO brightness and colour with C/2° (indoor daylight) are described in ISO 12625-15.
Tissue-Papier und Tissue-Produkte - Teil 7: Bestimmung der optischen Eigenschaften - Brightness- und Farbmessung mit Lichtart D65/10° (Außentageslicht) (ISO 12625-7:2021)
Dieses Dokument legt Prüfverfahren für die instrumentelle Bestimmung von Brightness und Farbe für Tissue-Papier und Tissue-Produkte unter Tageslichtbedingungen fest. Es werden auch genaue Anweisungen für die Vorbereitung von Messproben (einlagige, mehrlagige Produkte) und für die optischen Messungen von Produkten gegeben, bei denen besondere Vorsichtsmaßnahmen notwendig sein können.
ANMERKUNG Die als ISO Brightness und Farbe mit Lichtart C/2° (Tageslichtbedingungen in Innenräumen) bezeichneten Eigenschaften werden mit einem Gerät gemessen, das auf einen viel geringeren UV-Anteil angepasst ist als in diesem Dokument festgelegt wird. Die Messungen von ISO Brightness und Farbe mit Lichtart C/2° (Tageslichtbedingungen in Innenräumen) werden in ISO 12625 15 beschrieben.
Papier tissue et produits tissue - Partie 7: Détermination des propriétés optiques - Mesurage du degré de blancheur et de la couleur en D65/10° (lumière du jour extérieure) (ISO 12625-7:2021)
Le présent document spécifie des modes opératoires d’essai pour la détermination instrumentale du degré de blancheur et de la couleur des papiers tissue et des produits tissue observés dans les conditions de lumière du jour extérieure. Il donne également des instructions spécifiques pour la préparation des éprouvettes (produits à pli unique, produits multiplis) ainsi que pour les mesures optiques des produits, lorsque des précautions particulières peuvent se révéler nécessaires.
NOTE Les propriétés appelées degré de blancheur ISO et couleur C/2° (lumière du jour à l’intérieur) sont mesurées avec un appareil réglé à une teneur en UV très inférieure à celle spécifiée dans le présent document. Les mesurages du degré de blancheur ISO et de la couleur en C/2° (lumière du jour à l’intérieur) sont décrits dans l’ISO 12625-15.

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.

expressions related to conformity assessment, as well as information about ISO's adherence to the
World Trade Organization (WTO) principles in the Technical Barriers to Trade (TBT), see www .iso .org/

This document was prepared by Technical Committee ISO/TC 6, Paper, board and pulps, Subcommittee
SC 2, Test methods and quality specifications for paper and board, in collaboration with the European
Committee for Standardization (CEN) Technical Committee CEN/TC 172, Pulp, paper and board, in
accordance with the Agreement on technical cooperation between ISO and CEN (Vienna Agreement).
This third edition cancels and replaces the second edition (ISO 12625-7:2014), which has been
technically revised.
The main changes compared to the previous edition are as follows:
— alternative formulae in 11.2.1 have been removed because they were not relevant for tissue paper.
