This International Standard provides procedures for the laboratory determination of the total elemental sulphur and the sulphate half-ester content of cellulose nanocrystals (CNCs) by inductively coupled plasma-optical emission spectroscopy and conductometric titration, respectively, including sample preparation, measurement methods and data analysis. It is the intent for this Standard to apply to the characterization of CNCs (a) having all monovalent counterions (particularly hydronium and sodium cations), (b) which are either in the never-dried state in aqueous suspension, or have been re-dispersed from a dried form, and (c) which have been extracted from any naturally occurring cellulose source using a range of sulphuric acid hydrolysis conditions, or have been sulphated post-hydrolysis using sulphuric acid.

This part of ISO 7263 describes a method for the determination of the flat crush resistance of a corrugating medium after laboratory fluting using an A-flute geometry.

The procedure is applicable to any corrugating medium intended to be used, after fluting, in the manufacture of corrugated board.

NOTE ISO 7263-2 describes a method to determine the flat crush resistance using a B-flute geometry.

This part of ISO 12625 establishes general principles for the use of terms in the entire working field of tissue paper and tissue products.

It permits the use of a common terminology in industry and commerce.

It is expressly stated that ISO 15755 applies for the detection of impurities and contraries in tissue paper and tissue products.

For the determination of moisture content in tissue paper and tissue products ISO 287 applies.
