This

22、 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of an identical text or by endorsement, at the latest by September 2012, and conflicting national standards shall be withdrawn at the latest by September 2012. Attention is drawn to the possibility that some o

23、f the elements of this document may be the subject of patent rights. CEN and/or CENELEC shall not be held responsible for identifying any or all such patent rights. This document supersedes EN 13799:2002. This document has been prepared under a mandate given to CEN by the European Commission and the

24、 European Free Trade Association, and supports essential requirements of EU Directive(s). For relationship with EU Directive(s), see informative Annex ZA, which is an integral part of this document. For the purposes of this standard, contents gauges are considered a pressure accessory in accordance

25、with the Pressure Equipment Directive 97/23/EC in that they have a function additional to that of containing pressure. However, as they have a volume less than 0,1 l and a maximum allowable pressure (PS) of 25 bar, they are designed and manufactured in accordance with sound engineering practice of a

26、 Member State in order to ensure safe use. This document is considered as a supporting European Standard for the Pressure Equipment Directive 97/23/EC. This document has been submitted for reference into the RID and/or in the technical annexes of the ADR. The major changes to this revision include:

27、scope extended to include transportable equipment; gauge graduations and precision included; overfill Protection Device is deleted, now included in EN 13175; test requirement is included for non-metallic floats; torque test values have been changed; vacuum test and float test have been introduced; A

28、nnex C, production testing has been introduced; Annex D, vibration testing has been introduced; Annex E, environmental checklist has been introduced. According to the CEN/CENELEC Internal Regulations, the national standards organizations of the following countries are bound to implement this Europea

30、and the United Kingdom. DIN EN 13799:2012-06 EN 13799:2012 (E) 5 Introduction Protection of the environment is a key political issue in Europe and around the world. It is described here in its broadest sense. However, the total life cycle aspects of a product on the environment for example is what i

31、s meant. This includes expenditure of energy during all phases: mining of raw materials, fabrication, packaging, distribution, use, scrapping, recycling of materials, etc. NOTE Annex E indicates which clauses in this European Standard address environmental issues. Provisions have to be restricted to

32、 a general guidance. Limit values are specified in national laws. It is recommended that companies using this standard develop an environmental management policy. For guidance see ISO 14000 series. DIN EN 13799:2012-06 EN 13799:2012 (E) 6 1 Scope This European Standard specifies minimum requirements

33、 for design and testing of contents gauges, which are directly connected to LPG transportable pressure vessels, LPG drums, LPG cylinders and static LPG pressure vessels above 0,5 l water capacity excluding those used for automotive containers. This European Standard does not apply to refineries or o

34、ther process plants. 2 Normative references The following documents, in whole or in part, are normatively referenced in this document and are indispensable for its application.
