DESCRIPTION

BS EN ISO 12625-16:2024


This standard BS EN ISO 12625-16:2024 Tissue paper and tissue products is classified in these ICS categories:
  • 85.060 Paper and board
  • 85.080.20 Tissue paper
This document specifies the testing procedures for the instrumental determination of the opacity of tissue paper or tissue products by diffuse reflectance using a paper backing. This document 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.
