23、d This document (EN 12819:2009) has been prepared by Technical Committee CEN/TC 286 “Liquefied petroleum gas equipment and accessories”, the secretariat of which is held by NSAI. This document supersedes EN 12819:2002 and EN 12820:2002. This European Standard shall be given the status of a national
24、standard, either by publication of an identical text or by endorsement, at the latest by June 2010, and conflicting national standards shall be withdrawn at the latest by June 2010. Attention is drawn to the possibility that some of the elements of this document may be the subject of patent rights.
25、CEN and/or CENELEC shall not be held responsible for identifying any or all such patent rights. Users of this EN, prepared in the field of application of Article 118A of the EC Treaty, should be aware that standards have no formal legal relationship with Directives that may have been made under Arti
26、cle 118A of the Treaty. In addition, national legislation in the Member states may contain more stringent requirements than the minimum requirements of a Directive based on Article 118A. Information on the relationship between the national legislation implementing Directives based on Article 118A an
27、d this EN may be given in a national foreword of the national standard implementing this EN. The main modifications concern the following: merging of two European Standards: EN 12819:2002 and EN 12820:2002; improvement of Annex C which becomes normative; a new clause: normative references. According
28、 to the CEN/CENELEC Internal Regulations, the national standards organizations of the following countries are bound to implement this European Standard: Austria, Belgium, Bulgaria, Cyprus, Czech Republic, Denmark, Estonia, Finland, France, Germany, Greece, Hungary, Iceland, Ireland, Italy, Latvia, L

DIN EN 12819:2010-04 EN 12819:2009 (E) 5 Introduction Periodic and routine inspection and requalification regimes for LPG tanks greater than 13 m3have d
30、eveloped in various countries in different ways that range from defined to variable inspection periods with requalification regimes achieved by various methods. This European Standard for periodic and routine inspection and requalification is based on European countries legislation and codes of prac
31、tice and industries codes of practice. In addition, use of LPG in different applications has encouraged the industry to approach the requirements for routine and periodic inspection and requalification in different ways for each application. This European Standard calls for the use of substances and
32、 procedures that can be injurious to health if adequate precautions are not taken. It refers only to technical suitability and does not absolve the user from legal obligations relating to health and safety at any stage. It has been assumed in the drafting of this European Standard that execution of
33、its provisions is entrusted to appropriately qualified and experienced people. DIN EN 12819:2010-04 EN 12819:2009 (E) 6 1 Scope This European Standard specifies requirements for: a) routine inspection, periodic inspection and requalification of fixed LPG storage tanks of sizes greater than 13 m3, an
34、d associated fittings; b) marking tanks and/or keeping records, as appropriate, as a result of routine inspection, periodic inspection and requalification. This European Standard excludes refrigerated storage. 2 Normative references The following referenced documents are indispensable for the applic

44、be reported to the person responsible for safe operation of the tank/site, as appropriate, and action taken. 4.3 Leaks Any leak discovered from the tank or its fittings shall be reported immediately to the person responsible for safe operation of the tank. Action to make the tank or its fittings saf
45、e shall be taken by a competent person.
