EN ISO 12625-16:2015

Tissue paper and tissue products - Part 16: Determination of optical properties - Opacity (paper backing) - Diffuse reflectance method (ISO 12625-16:2015)

ISO 12625-16:2015 specifies the testing procedures for the instrumental determination of the opacity of tissue paper or tissue products by diffuse reflectance using a paper backing.
ISO 12625-16:2015 contains specific instructions for the preparation of test pieces of single-ply and multi-ply products, where special preparation/procedures might be necessary.
It can be used to determine the opacity of tissue paper and tissue products containing fluorescent whitening agents, provided the UV content of the radiation incident on the test piece has been adjusted to conform to that in the CIE illuminant C using a fluorescent reference standard provided by an authorized laboratory as described in ISO 2470-1.
ISO 12625-16:2015 is not applicable to coloured tissue paper and tissue products which incorporate fluorescent dyes or pigments.

Papier tissue et produits tissue - Partie 16: Détermination des propriétés optiques - Opacité sur fond papier - Méthode par réflexion en lumière diffuse (ISO 12625-16:2015)

L'ISO 12625-16:2015 spécifie les procédures d'essai pour la détermination instrumentale de l'opacité des papiers tissue ou des produits tissue, par réflexion en lumière diffuse, en utilisant un fond papier.
Elle contient également des instructions spécifiques pour la préparation des éprouvettes des produits à pli unique et produits multiplis, lorsque des préparations/procédures spécifiques peuvent se révéler nécessaires.
Elle peut être utilisée pour déterminer l'opacité de papiers tissue ou de produits tissue contenant des agents d'azurage fluorescents, à condition que la teneur en UV du rayonnement incident sur l'éprouvette ait été ajustée pour être rendue conforme à celle de l'illuminant C de la CIE, à l'aide d'un étalon de référence fluorescent fourni par un laboratoire agréé, tel que décrit dans l'ISO 2470-1.
L'ISO 12625-16:2015 ne s'applique pas aux papiers tissue et produits tissue colorés, comprenant des colorants ou des pigments fluorescents.
