Paper, board and pulps - Determination of dry matter content - Oven-drying method (ISO 638:2008)
ISO 638:2008 specifies an oven-drying method for the determination of the dry matter in paper, board and pulp.
The procedure is applicable to paper, board and pulp which does not contain any appreciable quantities of materials other than water that are volatile at the temperature of 105 °C ± 2 °C. It is used, for example, in the case of pulp, paper and board samples taken for chemical and physical tests in the laboratory, when a concurrent determination of dry matter content is required.
This method is not applicable to the determination of the dry matter content of slush pulp or to the determination of the saleable mass of pulp lots.
Papier, Pappe und Faserstoff - Bestimmung des Trockengehaltes - Wärmeschrankverfahren (ISO 638:2008)
Diese Internationale Norm legt ein Wärmeschrankverfahren für die Bestimmung des Trockengehaltes von Papier-, Pappe- und Zellstoff-Durchschnittsproben fest.
Dieses Verfahren ist auf Papier, Pappe und Zellstoff anwendbar, welche keine nennenswerten Mengen an anderem Material als Wasser aufweisen und welche bei einer Temperatur von (105 ± 2) °C nicht flüchtig sind. Im Fall von Zellstoff, Papier und Pappe beispielsweise werden Durchschnittsproben für chemische und physikalische Prüfungen im Labor entnommen, wenn gleichzeitig eine Bestimmung des Trockengehaltes gefordert ist.
Dieses Verfahren gilt nicht für die Bestimmung des Trockengehaltes von Zellstoffsuspensionen oder für die Bestimmung der verkaufsfähigen Masse von Zellstofflieferposten.
ANMERKUNG ISO 287[1] legt die Bestimmung des Feuchtegehaltes in einem Lieferposten Papier oder Pappe fest. ISO 4119[3] legt die Bestimmung der Stoffdichte von Faserstoff fest. ISO 801 (alle Teile)[2] legt die Bestimmung von verkaufsfähigen Massen in Lieferposten fest.
Papiers, cartons et pâtes - Détermination de la teneur en matières sèches - Méthode par séchage à l'étuve (ISO 638:2008)
L'ISO 638:2008 spécifie une méthode par séchage à l'étuve pour la détermination de la teneur en matières sèches d'échantillons de papier, de carton et de pâte.
La méthode est applicable au papier, au carton et à la pâte ne contenant pas des quantités appréciables de matières autres que l'eau, volatiles à la température de 105 °C ± 2 °C. Elle est utilisée, par exemple, dans le cas d'échantillons de pâte, de papier et de carton prélevés en vue d'analyses chimiques et physiques effectués en laboratoire lorsqu'il faut procéder à la détermination simultanée de la teneur en matières sèches.
Cette méthode n'est pas applicable pour la détermination de la teneur en matières sèches d'une suspension de pâte, ni pour la détermination de la masse marchande de lots de pâte.
