This document specifies the procedure for the determination of acid-soluble magnesium, calcium, manganese, iron, copper, sodium and potassium by atomic absorption spectrometry (AAS) or by inductively coupled plasma emission spectrometry (ICP/ES). The acid-soluble element comprises the acid-soluble part of the incineration residue, i.e. that part of the ignition residue obtained after incineration which is soluble in hydrochloric acid or nitric acid. In cases where the residue is completely solub...view more

This document 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.
This document 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.

detection which basically differ concerning the choice of the mobile and stationary phases. Deviating from this standard
further methods may be applicable if it can be shown that comparable results can be achieved. A validation must be carried
out by each laboratory.

This part of ISO 2470 is limited in its scope to white and near-white pulps, papers and boards. The
measurement can only be made in an instrument in which the ultraviolet energy level of the illumination
has been adjusted to correspond to the CIE illuminant C[6] using a fluorescent reference standard.
The CIE illuminant C is taken to be representative of i...
