This European Standard specifies a high performance liquid chromatographic (HPLC) method for the determination of the water-extractable phenols content of creosote. For reasons of precision, this standard is applicable to the determination of the water-extractable phenols content of creosotes containing more than 10 g of water extractable phenols per kilogram of creosote. The creosote sample is extracted with water. The aqueous extract is analyzed using high performance chromatography (HPLC) at constant temperature with a reversed phase packed column and isocratic elution. The result is compared with that from a known reference standard containing various phenols known to be extracted by water from creosote. Compared to DIN EN 1014-4:1995-09, the standard has been editorially revised. The Committee responsible for this standard is NA 042-03-06 AA "Spiegelausschuss zu CEN/TC 38 und ISO/TC 165/SC 1 Dauerhaftigkeit von Holz und Holzprodukten" ("Mirror Committee of CEN/TC 38 and ISO/TC 165/SC 1 Durability of wood and wood-based products") at DIN.
