Annex C is informative.According to the CEN/CENELEC Internal Regulations, the national standards organizations of the followingcountries are bound to implement this European Standard: Austria, Belgium, Czech Republic, Denmark, Finland,France, Germany, Greece, Hungary, Iceland, Ireland, Italy, Luxembourg, Malta, Netherlands, Norway, Portugal,Slovakia, Spain, Sweden, Switzerland and the United Kingdom.SIST EN 13991:2003



EN 13991:2003 (E)41 ScopeThis European Standard gives the specifications and the test methods for creosotes for industrial woodpreservation.Different grades of creosote are used depending on the desired properties of the treated wood.WARNING — The use of this European Standard may involve hazardous materials, operations andequipment. This standard cannot address all of the safety implications associated with its use. It is theresponsibility of the user of this standard to establish appropriate health and safety practices and assessthe applicability of regulatory limitations prior to use.
The warnings to use are covered in annex C.2 Normative referencesThis European Standard incorporates by dated or undated reference, provisions from other publications. Thesenormative references are cited at the appropriate places in the text and the publications are listed hereafter. Fordated references, subsequent amendments to or revisions of any of these publications apply to this EuropeanStandard only when incorporated in it by amendment or revision. For undated references the latest edition of thepublication referred to applies (including amendments).EN 1014-1, Wood preservatives - Creosote and creosoted timber - Methods of sampling and analysis -Part 1 : Procedure for sampling creosote.EN 1014-3, Wood preservatives - Creosote and creosoted timber - Methods of sampling and analysis -Part 3 : Determination of the benzoapyrene content of creosote.EN 1014-4, Wood preservatives - Creosote and creosoted timber - Methods of sampling and analysis -Part 4 : Determination of the water-extractable phenols content of creosote.EN 12303:2000, Coal tar based oils - Terminology.BS 144:1997, Coal tar creosote for wood preservation.EN ISO 2719, Determination of flash point - Pensky-Martens closed cup method (ISO 2719:2002)ISO 386, Liquid-in-glass laboratory thermometers - Principles of design, construction and use.ISO 760, Determination of water - Karl Fischer method (General method).3 Terms and definitionsFor the purposes of this European Standard, the following terms and definitions given in EN 12303:2000 apply.4 SamplingSampling of creosotes and preparation of samples.Samples for the assessment of the parameters listed in Table 1 shall be taken in accordance with EN 1014-1.5 Specifications and test methodsSpecifications for creosote grade A, B, C and the relevant test methods are given in Table 1.SIST EN 13991:2003

In contrast to grade A, the distillation residue is loweredin order to reduce the benzo[a]pyrene content. It is especially suitable for treatment of poles for overheadpower and telecommunication lines, and for structural timbers where bleeding in service can occur.Grade C excludes the lower boiling fraction allowable in the other types of creosote and because of the lowvolatility a reduction in odour is achieved.NOTE 2All types of creosotes are suitable for the hot-and-cold open-tank process.NOTE 3Creosote in use should not contain more than 3 % of water.NOTE 4The density is determined at a temperature above the crystallization temperature. For eachdegree Celsius above 20 °C, a fixed value of 0.7 kg/m3 is added to the density reading.SIST EN 13991:2003
