DIN EN 13575:2012-06 EN 13575:2012 (E) 4 1 Scope This European Standard specifies requirements for materials, physical properties and performance

27、for blow moulded and rotationally moulded polyethylene single tanks, with or without reinforcement, for the above ground storage of chemical liquids having a maximum specific gravity of 1 400 kg/m3except water and those liquids dealt with by EN 13341. It is only applicable to static blow moulded or

28、rotationally moulded polyethylene tanks, which are subjected to atmospheric pressures but not subject to any external loading and having a volume of 400 l to 10 000 l. Except for periodic temperature fluctuation their normal operating temperature does not exceed 25 C. Tanks according to this Europea

29、n Standard are expected to have a period of intended use of 10 years. This European Standard specifies test methods and factory production control tests as well. NOTE National and/or international regulations above and beyond the requirements of this standard may apply to the storage of liquids and

30、the installation of tanks. 2 Normative references The following documents, in whole or in part, are normatively referenced in this document and are indispensable for its application.
