EN 12817:2002 (E)5IntroductionPeriodic inspection and requalification regimes for overground LPG tanks up to and including 13 m3 havedeveloped in various countries in different ways, that range from defined to variable inspection periods withrequalification regimes achieved by various methods. This standard for periodic inspection and requalification isbased on European countries’ legislation and codes of practice and industry codes of practice. In addition, use ofLPG in different applications has encouraged the industry to approach the requirements for routine periodicinspection 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 adequateprecautions are not taken. It refers to technical suitability and does not absolve the user from legal obligationsrelating 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 toappropriately qualified and experienced people.1 ScopeThis European Standard specifies requirements for:a) routine inspection, periodic inspection and requalification of fixed above ground LPG storage tanks of sizesfrom 150 l up to and including 13 m3, and associated fittings;b) marking tanks and/or keeping records, as appropriate, as a result of routine inspection, periodic inspection andrequalification.This European Standard excludes refrigerated storage.2 Terms and definitionsFor the purposes of this European Standard, the following terms and definitions apply.2.1periodic inspectionexternal inspection of the visible parts of a tank and its fittings2.2routine inspectionexternal inspection of the visible parts of a tank and its fittings, carried out more frequently than periodic inspections2.3requalificationinspection/test carried out at intervals, typically at the time of a periodic inspection, in order to confirm that a tank isfit for a further period of service2.4competent bodyperson or corporate body, defined by a national competent authority, that, by appropriate qualification, training,experience, and resources, is able to make objective judgements related to inspection and testing of pressureequipment in LPG service2.5competent personperson who, by qualification, training, experience, and resources, is able to make objective judgements related toinspection and testing of pressure equipment in LPG serviceSIST EN 12817:2002
