Two New ISO Standards for Tissue Measurement



ANSI (American National Standards Institute) has just announced that two new optical standards have been published by ISO TC 6 (pulp, paper and paperboard) for the measurement of tissue.

ISO12625-15:2015  Tissue paper and tissue products -- Part 15: Determination of optical properties -- Measurement of brightness and colour with C/2° (indoor daylight) illuminant



ISO12625-16:2015  Tissue paper and tissue products -- Part 16: Determination of optical properties -- Opacity (paper backing) -- Diffuse reflectance method 

These standards have taken a while to be resolved. Experts from the United States and Canada have worked very hard to have these standards accepted by ISO since they are common measurements for tissue products in North America.  There was another standard that passed through the ISO system quickly due to partisan support of many European Experts.  The addition of Opacity and optical properties with UV Level C were added to complete the standards which reflect the practices and trade requirements of the entire worldwide Paper Industry.

ISO 12625-7:2014 Tissue paper and tissue products -- Part 7: Determination of optical properties -- Measurement of brightness and colour with D65/10° (outdoor daylight)
