19、d 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of an identical text or by endorsement, at the latest by August 2008, and conflicting national standards shall be withdrawn at the latest by August

20、 2008. 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. This European Standard has been submitted for reference into the RID (Regulatio

21、ns concerning the International Carriage of Dangerous Goods by Rail) and/or in the technical annexes of the ADR (European Agreement concerning the international carriage of Dangerous goods by Road). Therefore the standards listed in the normative references and covering basic requirements of the RID

22、/ADR not addressed within the present standard are normative only when the standards themselves are referred to in the RID and/or in the technical annexes of the ADR. The main changes between this version of the standard and the 2005 version is that this version combines EN 1439:2005, EN 14763:2005,

23、 EN 14794:2005 and EN 14913:2005 into a single standard. This European Standard supersedes EN 1439:2005, EN 14763:2005, EN 14794:2005 and EN 14913:2005. According to the CEN/CENELEC Internal Regulations, the national standards organizations of the following countries are bound to implement this Euro

24、pean Standard: Austria, Belgium, Bulgaria, Cyprus, Czech Republic, Denmark, Estonia, Finland, France, Germany, Greece, Hungary, Iceland, Ireland, Italy, Latvia, Lithuania, Luxembourg, Malta, Netherlands, Norway, Poland, Portugal, Romania, Slovakia, Slovenia, Spain, Sweden, Switzerland and the United

25、 Kingdom. DIN EN 1439:2008-06 EN 1439:2008 (E) 4 Introduction 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 rela

26、ting to health and safety at any stage. It has been assumed in the drafting of this European Standard that the execution of its provisions is entrusted to appropriately qualified and experienced people. Where judgements are called for, it has been assumed that they are made by competent persons who

27、have been trained specifically for the tasks. This standard is a combination of EN 1439:2005, with EN 14763:2005, EN 14794:2005 and EN 14913:2005. DIN EN 1439:2008-06 EN 1439:2008 (E) 5 1 Scope This European Standard specifies the procedures to be adopted when checking transportable refillable LPG c

28、ylinders before, during and after filling. This European Standard applies to transportable refillable LPG cylinders of water capacity from 0,5 l up to and including 150 l. This European Standard does not apply to cylinders permanently installed in vehicles, or to plant and filling equipment. This st

29、andard is applicable to the following: welded and brazed steel LPG cylinders with a specified minimum wall thickness (see EN 1442 and EN 12807 or an equivalent standard); welded steel LPG cylinders without specified minimum wall thickness (see EN 14140 or an equivalent standard); welded aluminium LP

30、G cylinders (see EN 13110 or an equivalent standard); composite LPG cylinders (see EN 14427 or an equivalent standard). Specific requirements for different types of cylinders are detailed in Annex A, Annex B, Annex C and Annex D. NOTE Rejection limits for a particular type of protected cylinder are

31、given in Annex G. This standard is intended to be applied to cylinders complying with RID/ADR (including pi marked cylinders) and also to existing non RID/ADR cylinder populations. 2 Normative references The following referenced documents are indispensable for the application of this document.

46、cylinder) are indicated; d) cylinder is within the test date as determined from the marked manufacture date or periodic inspection date; e) cylinder does not have defects as described in 4.4. For metallic cylinders, the inspection of the foot-ring for corrosion or damage shall determine the need for

47、 a more thorough external visual examination of the cylinder base; f) cylinder is fitted with a pressure relief valve, if required by the manufacturing standard.
