Title Durability of wood and wood-based products - Quantitative determination of pentachlorophenol in wood - Gas chromatographic method
Work Item Number 00038101
Abstract/Scope This Technical Report specifies a laboratory method of determining the pentachlorophenol content of wood. The method is applicable to all types of PCP- treated wood and wood-based materials as well as for the analysis of waste timber with respect to its PCP content. The method has a quantification limit corresponding to 100 µg PCP per kilogram of wood material expressed as dry matter. The method described has a measurement range up to PCP contents of 25 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 8.4). 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.

(1) Date of ratification (dor) date when the Technical Board notes the approval of an EN (and HD for CENELEC), from which time the standard may be said to be approved


(2) Date of availability (dav) date when the definitive text in the official language versions of an approved CEN/CENELEC publication is distributed by the Central Secretariat


(3) Date of announcement (doa) latest date by which the existence of an EN (and HD for CENELEC), a TS or a CWA has to be announced at national level


(4) Date of publication (dop) latest date by which an EN has to be implemented at national level by publication of an identical national standard or by endorsement


(5) Date of withdrawal (dow) latest date by which national standards conflicting with an EN (and HD for CENELEC) have to be withdrawn


(6) This list of normative references is purely indicative. The only official list of normative reference is the list of the published standard.


In the case of undated standard, a link to the last dated version is provided.


In the case of series, a link to each standard identified in the series is provided.


We also invite you to check (via the website) whether corrigenda and/or amendments shall be read in conjunction with the main standard.
