Pulps — Estimation of dirt and shives — Part 4: Instrumental inspection by reflected light using Equivalent Black Area (EBA) method |
ISO 5350-4:2006 specifies a method using instrumental inspection by reflected light for the estimation of visible dirt and shives in pulp manufactured in sheets, in terms of Equivalent Black Area (EBA) of dirt specks within the physical area range of 0,02 mm2 to 3,0 mm2. Using the algorithm prescribed in ISO 5350-4:2006, the maximum dirt size is limited to 3,0 mm2. Extension to other speck sizes (for example, those greater than 3,0 mm2 in physical area) may require changes in equipment, calculation procedures, or both, and is not covered in ISO 5350-4:2006. ISO 5350-4:2006 cannot be used for physical area measurements since it may not correctly measure the dirt specks for that mode of measurement.
The specimen to be evaluated should have a brightness, as determined by ISO 3688, of 30 % or greater. It may be necessary to reform some pulp sheets into laboratory sheets, if the surface is too rough or textured.
ISO 5350-4:2006 is also intended for recycled pulp.

Paper, board and pulps — Determination of pH of aqueous extracts — Part 1: Cold extraction |
ISO 6588-1:2012 specifies a method for the determination of the pH-value defined by the electrolytes extractable by cold water from a sample of paper, board or pulp.
ISO 6588-1:2012 is applicable to all types 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 ISO 6588-1:2012 is performed with distilled or deionised water, the pH-value measured will sometimes be different (e.g. for fully bleached pulp) from the pH-value measured under mill process conditions in which various types of process waters, e.g. chemically treated river water containing electrolytes, are used.
It is necessary to be aware that the results will not be the same when measuring pH according to ISO 6588-1:2012 and to ISO 29681. The difference can be significant especially when measuring pulps having a low ionic strength.
ISO 6588-2 differs from ISO 6588-1:2012 only as regards the extraction conditions. No general guidance can be given as to which of the two procedures (hot or cold) is best suited in a particular situation.
For cellulosic papers used for electrical purposes, the method used should be that given in IEC 60554-2

Paper — Determination of light scattering and absorption coefficients (using Kubelka-Munk theory) |
ISO 9416:2009 specifies a method for the calculation of light-scattering and light-absorption coefficients based upon diffuse reflectance measurements made under the conditions specified in ISO 2469 using the colour matching function and CIE illuminant C.
It is emphasized that the strict evaluation of the light-scattering and light-absorption coefficients requires conditions which cannot be achieved with the instrumentation specified here. The values obtained by application of ISO 9416:2009 are dependent on the application of the Kubelka-Munk equations, not to full reflectance data but to reflectance factor data obtained using the specified d/0° geometry and a gloss trap.
The use of the method is restricted to white and near-white uncoated papers with an opacity less than about 95 %. Paper that has been treated with a fluorescent dyestuff or that exhibits significant fluorescence can only be dealt with if a filter with a cut-off wavelength of 420 nm is used to eliminate all the fluorescence effect in the UVex(420) mode.

This method will only capture those Stickies and Plastics which are retained on the screen of a given slit size. It
should be noted that this will probably not be the total amount of Stickies and Plastics that are actually present in a
given pulp sample.

ISO 15360-2:2015 specifies a method to estimate Stickies and Plastics in all grades of recycled pulp. It applies the principles for the separation of Stickies and Plastics described in ISO 15360‑1. The visualization and counting techniques described in ISO 15360‑1 are replaced here by image analysis.
ISO 15360-2:2015 permits the use of different laboratory screening devices as well as screens of different sizes when applying the specified method. It is impracticable to define more closely the equipment or screen sizes to be used, because of the wide range of Stickies and Plastics found in recycled pulps, and the various screening devices which are being successfully used for their measurement.
NOTE This method will only estimate those Stickies and Plastics which are tacky and which are retained on the screen of a given slit size under the temperature and pressure conditions of this test method. It is important to note that this will probably not be the total amount of Stickies and Plastics that are actually present in a given pulp sample.

Pulp and paper — Determination of the effective residual ink concentration (ERIC number) by infrared reflectance measurement |
ISO 22754:2008 specifies a method for the determination of the effective residual ink concentration (ERIC number) by infrared reflectance measurement.
ISO 22754:2008 is applicable to all types of deinked, recycled pulp and to sheets of machine-made paper made from recycled pulp, where the residual ink is black. The method is applicable to materials available in sheet form only if the opacity at 950 nm is less than 97 %. The ERIC number obtained is dependent on the distribution of ink particle sizes, and the method is most effective for submicron particles. The value obtained is reliable only if the test material is uniform in ink distribution, formation, and grammage such that presenting different parts of the sheet to the measuring aperture of the reflectometer produces very similar readings.

Pulps — Kraft liquor — Determination of residual alkali using potentiometric titration |
This document describes a procedure for determining the content of residual alkali in Kraft black liquors having a dry matter content up to 40 %.
The method is based on a potentiometric titration with hydrochloric acid and is intended for black liquor samples with an initial pH ≥ 11,0.
The lower limit of determination is 0,1 g/l of eq. NaOH.

Paper, board and pulps — Determination of pH of salted water extracts |
ISO 29681:2009 specifies a method for the determination of the pH of an aqueous extract of paper, board and pulps, in which the soaking and the measuring are performed in salted water (0,1 M KCl solution).
ISO 29681:2009 is applicable to all kinds of paper, board and pulps, but is specifically applicable to bleached pulps from virgin fibres and to pulp samples having a low ionic strength for which the pH-value using this International Standard will give more realistic results related to mill conditions than those obtained with ISO 6588-1 or ISO 6588-2.
