SPÉCIFICATION TECHNIQUE
TECHNISCHE SPEZIFIKATION
March 2003
ICS 59.140.30
English version
Leather – Chemical tests – Determination of the content of
pentachlorophenol in leather
This Technical Specification (CEN/TS) was approved by CEN on 27 October 2002 for provisional application.
The period of validity of this CEN/TS is limited initially to three years. After two years the members of CEN will be requested to submit their
comments, particularly on the question whether the CEN/TS can be converted into a European Standard.
CEN members are required to announce the existence of this CEN/TS in the same way as for an EN and to make the CEN/TS available. It
is permissible to keep conflicting national standards in force (in parallel to the CEN/TS) until the final decision about the possible
conversion of the CEN/TS into an EN is reached.
CEN members are the national standards bodies of Austria, Belgium, Czech Republic, Denmark, Finland, France, Germany, Greece,
Hungary, Iceland, Ireland, Italy, Luxembourg, Malta, Netherlands, Norway, Portugal, Slovakia, Spain, Sweden, Switzerland and United
Kingdom.

Foreword
This document (CEN/TS 14494:2003) has been prepared by CEN/TC 289, "Leather" the Secretariat of which is
held by UNI.
It is based on the English translation of DIN 53313 Draft 1999 and describes a procedure where PCP is acetylated
before the chromatographic detection and the amount of the detected PCP acetate is quantified via an internal
standard correction.
According to the CEN/CENELEC Internal Regulations, the national standards organizations of the following
countries are bound to anounce this European Standard: Austria, Belgium, Czech Republic, Denmark, Finland,
France, Germany, Greece, Hungary, Iceland, Ireland, Italy, Luxembourg, Malta, Netherlands, Norway, Portugal,
Slovak Republic, Spain, Sweden, Switzerland and the United Kingdom.
Annex A is informative.

1 Scope
This Technical Specification specifies a method for determining the content of pentachlorophenol (PCP), its salts
and esters in leather.
2 Normative references
This Technical Specification 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 to this Technical
Specification 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
First of all the leather is submitted to steam distillation.
After extraction into n-hexane the PCP is acetylated by acetic anhydride and the PCP acetates analysed by gas
chromatography with an ECD detector. Quantification is performed by an external standard and correction made
with an internal standard.
4 Definitions
The concentration of pentachlorophenol can consist of free pentachlorophenol, its salts and esters. PCP is
detected gas-chromatographically as it’s derivative, PCP acetate. The PCP content is given in mg/kg sample.
