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.<\/p>\n

\n
\n NOTE\n <\/div>\n

The properties called ISO brightness and colour with C\/2\u00b0 (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\u00b0 (indoor daylight) are described in ISO 12625-15<\/span><\/span> .<\/p>\n<\/div>\n
