Determination of particle size distribution by gravitational liquid sedimentation methods — Part 5: ...
This part of ISO 13317 describes and principles and proper use of gravitational photosedimentation techniques for the characterisation of dispersed phases of suspensions and emulsions. These techniques monitor the gravity-induced phase separation of particulate materials dispersed in liquids by recording photometric signals (i.e., intensity of transmitted or scattered light) as function of…
Paper and Pulp — Deinkability test for printed paper product mixtures containing woodfree printed pa...
This document specifies a basic laboratory test method for deinkability of woodfree printed paper products under alkaline conditions by means of single stage flotation deinking and fatty acid-based collector chemistry. The woodfree printed paper product of interest is tested as a mixture containing 10% by weight of the woodfree printed paper with the balance comprising a mixture of mechanical…
