Paper and board - Estimation of contraries (ISO 15755:1999)

Paper and board - Estimation of contraries (ISO 15755:1999)

This European Standard specifies the test method for the estimation by reflected light of the visible contraries in paper. Visual inspection is applicable to most kinds of paper and board. Paper and board with an apparently high content of contraries require to be inspected by instrumental means as described in Annex B, as the tedium of large counts diminishes the judges' precision. However, papers which are not flat, have a low lightness (value below 30 %) and contain holes that may cause particular problems for instrumental techniques (see Annex B).

Papier und Pappe - Schätzung von Verunreinigungen (ISO 15755:1999)

Diese Europäische Norm legt das Prüfverfahren mit reflektierendem Licht fest, das zur Scha(tzung von sichtbaren Verunreinigungen in Papier dient. Die visuelle Pru(fung ist fu(r die meisten Sorten von Papier und Pappe anwendbar. Papiere und Pappen mit einem offensichtlichen, hohen Anteil an Verunreinigungen erfordern, wir in Anhang B festgelegt, instrumentell gepru(ft zu werden, damit das zeitaufwendige Außa(hlen ohne Pra(zisionsverlust verku(rzt wird.

Papiers et cartons - Estimation des défauts (ISO 15755:1999)

La présente norme européenne spécifie la méthode d'essai d'estimation sous lumiere réfléchie des défauts visibles dans le papier.  L'examen visuel est applicable a la plupart des sortes de papiers et cartons. Les papiers et cartons avec un taux de défauts apparemment élévé nécessitent d'etre examinés au moyen de dispositfs automatiques comme décrit dans l'annexe B, car l'ennui provoqué par de grands dénombrements diminue la précision du jugement des observateurs.

This document is not applicable for paper of grammage less than 50 g/m2 or embossed paper. It is not applicable for porous papers such as newsprint or papers such as blotting paper or other papers having a relatively high-water absorptiveness for which ISO 8787 is more suitable.

Paper, board and pulps — Determination of pH of aqueous extracts — Part 2: Hot extraction
ISO 6588-2:2021

This document specifies a method for the determination of the pH-value defined by the electrolytes extractable by hot water from a sample of paper, board or pulp.
This document is applicable to all kinds of paper, board and pulp.
As the quantity of extractable ionic material approaches zero, as in the case of highly purified pulps, the precision of the method becomes poor because of the difficulties encountered in making pH measurements on water containing little electrolytic material.
Since the extraction in this document is performed with distilled or deionised water, the pH-value measured can sometimes be different (e.g. fully bleached pulp) from the pH-value measured under mill process conditions in which various types of process waters, such as chemically treated river water containing electrolytes, are used. In such cases, ISO 29681 can be used instead, as it is specifically applicable to bleached pulps from virgin fibres and to pulp samples having a low ionic strength for which the pH value gives more realistic results related to mill conditions than those obtained with this document. For cellulosic papers used for electrical purposes, the method used can be that given in IEC 60554-2[5].

ISO 1762:2019

This document describes the determination of the residue (ash content) on ignition of paper, board, pulps and cellulose nanomaterials at 525 °C. It is applicable to all types of paper, board, pulp and cellulose nanomaterial samples.
This document provides measurement procedures to obtain a measurement precision of 0,01 % or better for residue (ash content) on ignition at 525 °C.
Determination of residue (ash content) on ignition at 900 °C of paper, board, pulps and cellulose nanomaterials is described in ISO 2144.
In the context of this document, the term "cellulose nanomaterial" refers specifically to cellulose nano-object (see 3.2 to 3.4). Owing to their nanoscale dimensions, these cellulose nano-objects can have intrinsic properties, behaviours or functionalities that are distinct from those associated with paper, board and pulps.
