DESCRIPTION
CSN EN ISO 12625-7
CSN EN ISO 12625-7 This part of ISO 12625 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. NOTE The properties called C/2° brightness and colour are measured with an instrument adjusted to a much lower UV content than that specified in this part of ISO 12625. The measurements of C/2° brightness and colour are described in ISO 12625 15. Original English text of CSN EN Standard. The price of the Standard included all amendments and correcturs.
