Assessment of carry-over, from the incorporation of additives to the loading of finished products

Within the framework of developing the methodology for assessing carry-over on industrial sites, in 1999 Tecaliman carried out two tests during the course of which carry-over was assessed using a number of additives, as far as the pellet loading station (Tecaliman, 2000a, 2000b). The aim of these two assessments, which are summarised here, was to determine the best location in the plant for valid and effective assessment of carry-over. After several years implementing approval procedures and the “desire” of certain industrial operators to carry out these kinds of tests, urged on by DSVs, it appeared useful to note that these tests were carried out, how they were carried out and what their conclusions were.
