Tissue paper and tissue products - Part 7: Determination of optical properties - Measurement of brightness and colour with D65/10° (outdoor daylight) (ISO 12625-7:2014)
ISO 12625-7:2014 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 may be necessary.
Tissue-Papier und Tissue-Produkte - Teil 7: Bestimmung der optischen Eigenschaften - Brightness- und Farbmessung mit Lichtart D65/10° (Außentageslicht) (ISO 12625-7:2014)
Dieser Teil der ISO 12625 legt Prüfverfahren für die instrumentelle Bestimmung von Brightness und Farbe
von Tissue-Papier und Tissue-Produkten fest. Sie gibt außerdem spezielle Anleitungen für die
Probenvorbereitung (einlagige-, mehrlagige Produkte) und für die optischen Messungen, für die besondere
Vorkehrungen notwendig sein können.

L'ISO 12625-7:2014 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 dans les conditions de lumière du jour extérieure. Elle 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.
Tissue papir in izdelki iz tissue papirja - 7. del: Določevanje optičnih lastnosti - Merjenje svetlosti in barve z D65/10° (zunanja dnevna svetloba) (ISO 12625-7:2014)
Ta del standarda ISO 12625 določa preskusne postopke za instrumentalno določevanje svetlosti in barve tissue papirja ter proizvodov iz tissue papirja, opazovanih na zunanji dnevni svetlobi. Določa tudi posebna navodila za pripravo preskusnih vzorcev (proizvodi z enim slojem, več sloji) in za optično merjenje proizvodov, pri čemer so lahko potrebni posebni zaščitni ukrepi. OPOMBA: Lastnosti, ki se imenujejo C/2°, svetlost in barva, se merijo z instrumentom, prilagojenim na veliko nižjo UV-vsebnost od vsebnosti, opredeljene v tem delu standarda ISO 12625. Meritve C/2°, svetlosti in barve so opisane v standardu 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.
