This document specifies a method to measure the energy required to rapidly delaminate a test piece of paper or board. Rupture of the test piece in the “Z” or thickness direction is initiated by a pendulum having a defined mass, moving at a defined velocity. The procedure is suitable for both single- and multi-ply papers and boards, including coated sheets and those that are laminated with synthetic polymer films. It is particularly suitable for papers and boards that can be subjected to z-direction rapid impacts, impulses or shock loads during printing or conversion. The test procedure entails the adherence of double-sided adhesive tape to both sides of the test piece under pressure. For this reason, the method is unsuitable for materials that can be structurally damaged by compression or are porous enough to permit migration of the tape adhesive into or through the test piece.

This document specifies a method for determination of the drainability of water from a pulp suspension in terms of the “Canadian Standard” freeness method in millilitres. In principle, this method is applicable to all kinds of pulp in aqueous suspension. NOTE Treatments of pulp suspensions which produce a large proportion of fines can induce an anomalous rise in freeness (false freeness), as a rule at values below 100 ml.

This document specifies the requirements for archival paper. It is applicable to unprinted papers intended for documents and publications required for permanent retention and frequent use. For these documents and publications, paper of high permanence and high durability is required. NOTE 1 Archival paper is primarily required for documents and publications intended to be kept permanently because of their high historical, legal or other significant value. Archival paper is for special purposes, not for common use. The use of the term “archival paper” does not imply that all papers kept in archives are “archival papers”. NOTE 2 For relationships between International Standards on paper permanence (ISO 9706), on archival paper permanence and durability (ISO 11108), and on paper stability for general graphic applications (ISO 20494), refer to Annex B.

This document covers physical properties and manufacturing requirements for envelopes having an address window and the flap on the front side once the flap has been sealed, hereafter the flap side. It covers the main design features of the reverse envelope, notably of the flap and address window, and the materials used for the manufacturing thereof. It applies to reverse envelopes with advertising or communication printed on the plain side, eventually on its entire surface.
This document covers empty envelopes, but also finished mailpieces that have been properly inserted, addressed and franked (reverse mailpieces) and are submitted to Postal Operators. In particular, reverse mailpieces will be compliant with relevant Postal standards applicable in the member states.
By extension, these requirements also apply to non-window envelopes used for reverse mailpieces and having the address printed on the flap side.
This document does not apply to:

This document describes the thermal analysis of kraft lignin using thermogravimetric methods. Thermogravimetry can be used to determine the initial decomposition temperature(s), rate(s) of decomposition, and the temperature at maximum decomposition of various materials, including lignins at atmospheric pressure. All these temperatures are solely based on the mass loss and are not necessarily the real decomposition temperatures, because not all decompositions can generate evaporation at atmospheric pressure. Thus, these values are only for comparison purposes. This procedure is applicable to solid lignins (e.g., powdered form) isolated using different isolation techniques (e.g., acidification with hydrochloric acid, sulphuric acid, etc., and carbonation using gaseous carbon dioxide) from the spent liquor (black liquor) generated in the kraft pulping process. It does not apply to raw black liquor. Thermogravimetric measurement may be performed under different types of atmosphere, e.g., an inert atmosphere or an oxidative atmosphere.

This document specifies a test method for the determination of the wet tensile strength of tissue paper and tissue products after soaking with water, using a tensile-strength-testing apparatus operating with a constant rate of elongation.
Currently, two types of tensile-strength-testing apparatus are commercially available, one where the test piece is positioned vertically and, for the other, horizontally. This document applies for both. For vertical tensile-strength-testing apparatus, a device that is held in the lower grip of the tensile-strength-testing apparatus, called a Finch Cup, is used to achieve the wetting. For horizontal tensile-strength-testing apparatus, the soaking device is placed between the two clamps.
This document is not applicable to cases where impurities and contraries are determined.

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].
