EN 12819:2009 (E) 5 Introduction Periodic and routine inspection and requalification regimes for LPG tanks greater than 13 m3 have developed 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 practice 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 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 its provisions is entrusted to appropriately qualified and experienced people. SIST EN 12819:2010
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, and 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 application of this document.
