This European Standard shall be given the status of a national standard, either by publication of an identical text or by endorsement, at the latest by January 2001, and conflicting national standards shall be withdrawn at the latest by January According to the CEN/CENELEC Internal Regulations, the national standards organizations of the following countries are bound to implement this European Standard: Austria, Belgium, Czech Republic, Denmark, Finland, France, Germany, Greece, Iceland, Ireland, Italy, Luxembourg, Netherlands, Norway, Portugal, Spain, Sweden, Switzerland and the United Kingdom.
6 Page 4 EN 12567: Scope This European Standard specifies the general performance requirements of isolating valves (gate valves, globe valves, plug and ball valves and butterfly valves) used in the production, storage, transmission (by pipeline, rail, road or sea) of Liquefied Natural Gas (LNG). LNG filling valves for vehicule refuelling systems are excluded from the scope of this standard. DN range from DN 8 to DN PN range from PN 16 to PN 100. Class range from Class 150 to Class 900. Temperature range from 196 C to + 60 C. 2 Normative references This European Standard incorporates by dated or undated reference, provisions from other publications.
