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. 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 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. 4 Reagents 4.1 Acetonitrile HPLC grade. 4.2 Water according to grade 1 of EN ISO 3696:1995. 4.3 Methanol HPLC grade. 4.4 Acetic acid, HPLC grade. 4.5 Phenol purity 98 % (m/m) minimum. 4.6 2-methylphenol (o-cresol) purity 98 % (m/m) minimum. 4.7 3-methylphenol (m-cresol) purity 98 % (m/m) minimum. 4.8 4-methylphenol (p-cresol) purity 98 % (m/m) minimum. 4.9 1,2-dihydroxybenzene (catechol) purity 98 % (m/m) minimum. 4.10 1,3-dihydroxybenzene (resorcinol) purity 98 % (m/m) minimum. 4.11 1,4-dihydroxy
