Foreword
This document (EN ISO 15320:2003) has been prepared by Technical Committee CEN/TC 172 "Pulp, paper and
board", the secretariat of which is held by DIN, in collaboration with Technical Committee ISO/TC 6 "Paper, board
and pulps".
This European Standard EN ISO 15320:2003 including the Amendment shall be given the status of a national
standard, either by publication of an identical text or by endorsement, at the latest by June 2004, and
conflicting national standards shall be withdrawn at the latest by June 2004.
WARNING: The use of this European Standard may involves hazardous materials, e.g. methanol and
pentachlorophenol, which are toxic substances, as well as acetic anhydryde, which is corrosive. This
European Standard does not address all the safety and environmental problems associated with its use. It
is the responsibility of the user of this European Standard to establish appropriate safety, health and
environmental practices and determine applicability of safety regulations prior to use.
According to the CEN/CENELEC Internal Regulations, the national standards organizations of the following
countries are bound to implement this European Standard: Austria, Belgium, Czech Republic, Denmark, Finland,
France, Germany, Greece, Hungary, Iceland, Ireland, Italy, Luxembourg, Malta, Netherlands, Norway, Portugal,
Slovakia, Spain, Sweden, Switzerland and the United Kingdom.
1 Scope
This European Standard specifies a test method for the determination of pentachlorophenol (PCP) in an aqueous
extract in pulp, paper and board. Though it is developed for paper and board intended to come into contact with
foodstuffs, it is applicable to all kinds of pulp, paper and board.
NOTE 1 It was investigated that a hot water extract (acc. to EN 647) is sufficient for the determination of PCP in pulp, paper
and board.
The working range for the method is 0,05 mg/kg to 0,5 mg/kg.
NOTE 2 The upper limit of the working range could be increased if the aqueous extract is diluted.
2 Normative References
This European Standard incorporates by dated or undated reference, provisions from other publications. These
normative references are cited at the appropriate places in the text and the publications are listed hereafter. For
dated references, subsequent amendments to or revisions of any of these publications apply in this European
Standard only when incorporated in it by amendment or revision. For undated references the latest edition of the
publication referred to applies (including amendments).

3 Principle
A specimen of the material to be tested is extracted with cold water according to EN 645 or with hot water
according to EN 647. The pentachlorophenol in the extract is concentrated using solid phase extraction on a phenyl
column. The pentachlorophenol is then eluted from the phenyl column with hexane, acetylated using acetic
anhydride and the amount of pentachlorophenol present determined using gas chromatography employing an ECD
(electron capture detector) or MS (mass spectrometer) detector. The result is expressed as milligrams per kil
