6、zu CEN/TC 286. Some provisions of this European Standard are not in accordance with German national regulations governing the operation of LPG tanks in Germany (see A-deviations in Annex K), particularly the Betriebssicherheits-verordnung (BetrSichV) (Ordinance on industrial safety and health). The
7、Ordinance classifies LPG tanks as systems requiring monitoring which are therefore subject to legally binding requirements such as those relating to inspections. The specifications of the Ordinance are given more detail in the Technische Regeln fr Betriebssicherheit (TRBS) (Technical rules for indus
8、trial safety and health). It should therefore be noted that these German national regulations are more legally binding than the present standard. The TRBS regulations are obtainable at the website of the Federal Institute for Occupational Safety and Health (BAuA), at www.baua.de. Amendments This sta
9、ndard differs from DIN EN 12817:2006-06 and DIN EN 12818:2006-05 as follows: a) The contents of the standards have been combined into one standard. b) Annex C (normative) “Acoustic emission testing” has been revised. c) Clause 2 “Normative references” has been added. d) An A-deviation has been inclu
10、ded in Annex K referring to the German Betriebssicherheitsverordnung (BetrSichV) (Ordinance on industrial safety and health). e) The standard has been brought in line with the current rules of presentation.

29、uipment and accessories”, the secretariat of which is held by NSAI. This 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of an identical text or by endorsement, at the latest by July 2010, and conflicting national standards shall be withdrawn at the latest b
30、y July 2010. Attention is drawn to the possibility that some of 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. Users of this standard, prepared in the field of application of Article 1
31、18A of the EC Treaty, should be aware that standards have no formal legal relationship with Directives that may have been made under Article 118A of the Treaty. In addition, national legislation in the Member states may contain more stringent requirements than the minimum requirements of a Directive
32、 based on Article 118A. Information on the relationship between the national legislation implementing Directives based on Article 118A and this EN may be given in a national foreword of the national standard implementing this EN. This document supersedes EN 12817:2002 and EN 12818:2002. The main mod
33、ifications concern the following: merging of two European Standards: EN 12817:2002 and EN 12818:2002; improvement of Annex C which becomes normative; a new clause: Clause 2, Normative references. According to the CEN/CENELEC Internal Regulations, the national standards organizations of the following
34、 countries are bound to implement this European Standard: Austria, Belgium, Bulgaria, Croatia, Cyprus, Czech Republic, Denmark, Estonia, Finland, France, Germany, Greece, Hungary, Iceland, Ireland, Italy, Latvia, Lithuania, Luxembourg, Malta, Netherlands, Norway, Poland, Portugal, Romania, Slovakia,

DIN EN 12817:2010-06 EN 12817:2010 (E) 6 Introduction Periodic inspection and requalification regimes for LPG tanks up to and including 13 m3have developed in various countries in different ways that range from defined to variable inspect
36、ion periods with requalification regimes achieved by various methods. This European Standard for periodic inspection and requalification is based on European countries legislation and codes of practice and industry codes of practice. In addition, use of LPG in different applications has encouraged t
37、he industry to approach the requirements for routine 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 to technical sui
38、tability 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. DIN EN 12817:2010-06 EN 12817:2010
39、(E) 7 1 Scope This European Standard specifies requirements for: a) routine inspection, periodic inspection and requalification of fixed LPG storage tanks of sizes from 150 l up to and including 13 m3, and associated fittings; b) marking tanks and/or keeping records, as appropriate, as a result of r
40、outine inspection, periodic inspection and requalification.
