Biological durability of wood and wood-based products - Quantitative determination of pentachlorophenol in wood - Gas chromatographic method

Edition date: 2026-09-16
In Force
Available languages: English, German
Summary: This document specifies a laboratory method of determining the pentachlorophenol content of wood. The method is applicable to all types of pentachlorophenol (PCP) in woods and wood-based materials as well as for the analysis of waste timber with respect to its pentachlorophenol (PCP) content. The method described has a measurement range from 250 µg/kg up to pentachlorophenol (PCP) contents of 5 mg/kg of dry matter. These figures refer to the given example (where an aliquot of 1 ml of the extract is used for acetylation, see 9.3). NOTE 1 If lower quantification limits are required, a higher volume of extract aliquot can be used for derivatisation. NOTE 2 This method could have some modifications with some wood species as hardwoods. In general, in the case of complex matrix, a method using mass spectrometry can be used.

Le présent document spécifie une méthode de laboratoire permettant de déterminer la teneur en pentachlorophénol du bois. La méthode s'applique à tous les types de pentachlorophénol (PCP) présents dans le bois et les matériaux dérivés du bois, ainsi qu'à l'analyse des déchets de bois en ce qui concerne leur teneur en pentachlorophénol (PCP). La plage de mesure dans la méthode décrite spécifie une teneur en pentachlorophénol (PCP) dans la matière sèche qui s'étend de 250 µg/kg jusqu'à 5 mg/kg. Ces chiffres se réfèrent à l'exemple donné (dans lequel un aliquote de 1 ml de l'extrait est utilisé pour l'acétylation, voir 9.3). NOTE 1 Si des limites de quantification inférieures sont exigées, il est possible d'utiliser un extrait aliquote de plus grand volume pour la dérivation. NOTE 2 Il est possible d'apporter quelques modifications à cette méthode pour quelques essences de bois telles que des feuillus. En général, dans le cas d'une matrice bois complexe, une méthode ayant recours à la spectrométrie de masse peut être utilisée.

Dieses Dokument legt ein Laborverfahren zur Bestimmung des Pentachlorphenol (PCP)-Gehalts von Holz fest. Das Verfahren ist bei allen Arten von Pentachlorphenol (PCP) in Holz und Holzprodukten anwendbar sowie zur Analyse von Altholz in Bezug auf den Gehalt von Pentachlorphenol (PCP). Das beschriebene Verfahren ist anwendbar von 250 µg/kg bis zu einem Pentachlorphenol (PCP)-Gehalt von 5 mg/kg Trockensubstanz. Diese Angaben beziehen sich auf das angegebene Beispiel (in dem ein Aliquot von 1 ml des Extraktes für die Acetylierung verwendet wird, siehe 9.3). ANMERKUNG 1 Sind niedrigere Bestimmungsgrenzen erforderlich, kann ein größeres Extraktvolumen als Aliquot für die Derivatisierung verwendet werden. ANMERKUNG 2 Bei einigen Holzarten, wie z. B. Laubholz, können Änderungen dieses Verfahrens erforderlich sein. Im Allgemeinen kann bei einer komplexen Matrix ein Verfahren mit Massenspektrometrie angewendet werden.
