This standard is only applicable to creosotes containing more than 30 mg/kg benzo(a)pyrene. 2 Normative references The following referenced documents are indispensable for the application of this document. For dated references, only the edition cited applies. For undated references, the latest edition of the referenced document (including any amendments) applies. EN ISO 3696:1995, Water for analytical laboratory use

Specification and test methods (ISO 3696:1987) 3 Principle The creosote sample is diluted to an appropriate concentration with an acetonitrile/water mixture. The diluted sample is analyzed using high performance liquid chromatography (HPLC) at constant temperature with a reverse phase packed column and isocratic elution. The result is compared with that from a known reference standard. 4 Reagents 4.1 Acetonitrile − water mixture. Add 220 ml of water (according to grade 1 of EN ISO 3696:1995) to 780 ml of acetonitrile (CH3CN, HPLC grade) and mix thoroughly. The mixture shall be at room temperature before use. 4.2 Benzo(a)pyrene solution, containing approximately
