Tissue paper and tissue products - Determination of optical properties. Measurement of brightness and colour with C/2° (indoor daylight) illuminant Ingestion-build-86103 This European Standard is applicable1 Scope This part of ISO 12625 specifies testing procedures for the instrumental determination of brightness and colour of tissue paper and tissue products viewed in indoor 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. NOTE The properties called D65 brightness and colour are measured
