Paper, board and pulps — Measurement of diffuse radiance factor (diffuse reflectance factor)
Käsitlusala:
This document describes the general procedure for measuring the diffuse radiance factor of all types of pulp, paper and board. More particularly, it specifies in detail the procedures to be used for calibrating the equipment, and in Annex A, the characteristics of the equipment to be used for such measurements.
This document can be used to measure the diffuse radiance factors and related properties of materials containing fluorescent whitening agents, provided that the UV-content of the instrument illumination has been adjusted to give the same level of fluorescence as a fluorescent reference standard for a selected CIE illuminant, according to the International Standard describing the measurement of the property in question.
Annex C describes the preparation of fluorescent reference standards.

Corrugated fibreboard - Determination of flat crush resistance (ISO/DIS 3035:2024)
Käsitlusala:
This International Standard specifies a method for the determination of the flat crush resistance of corrugated fibreboard used in the manufacture of shipping containers.
This International Standard is applicable to single-faced and single-wall (double-faced) corrugated fibreboard.
This International Standard is not applicable to double-wall (double-double-faced) corrugated fibreboard and to microflute corrugated fibreboard, since the end-point of the test is not clearly defined or observable.

Information and documentation - Paper for documents - Requirements for permanence (ISO/DIS 9706:2024)
Käsitlusala:
Specifies the requirements for permanent paper intended for documents given in terms of minimum strength measured by a tear test, minimum content of substance (such as calcium carbonate) that neutralize acid action measured by the alkali reserve, maximum content of easily oxidized material measured by the kappa number, maximum and minimum pH values of a cold water extract of the paper. Is applicable to unprinted papers. Is not applicable to boards.
