17、EN 1439:2008 (E) 3 Foreword This document (EN 1439:2008) has been prepared by Technical Committee CEN/TC 286 “Liquefied petroleum gas equipment 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 o
18、f an identical text or by endorsement, at the latest by August 2008, and conflicting national standards shall be withdrawn at the latest by August 2008.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
19、be held responsible for identifying any or all such patent rights. This European Standard has been submitted for reference into the RID (Regulations concerning the International Carriage of Dangerous Goods by Rail) and/or in the technical annexes of the ADR (European Agreement concerning the interna
20、tional carriage of Dangerous goods by Road). Therefore the standards listed in the normative references and covering basic requirements of the RID/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
21、 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, 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. A
22、ccording 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, L
23、atvia, Lithuania, Luxembourg, Malta, Netherlands, Norway, Poland, Portugal, Romania, Slovakia, Slovenia, Spain, Sweden, Switzerland and the United Kingdom. BS EN 1439:2008EN 1439:2008 (E) 4 Introduction This European Standard calls for the use of substances and procedures that can be injurious to he
24、alth 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 the execution of its provisions is entrusted to appr
25、opriately qualified and experienced people. Where judgements are called for, it has been assumed that they are made by competent persons who 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. BS EN 1439:2
26、008EN 1439:2008 (E) 5 1 Scope This European Standard specifies the procedures to be adopted when checking transportable refillable LPG cylinders 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
27、 150 l. This European Standard does not apply to cylinders permanently installed in vehicles, or to plant and filling equipment. This standard 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 stan
28、dard); welded steel LPG cylinders without specified minimum wall thickness (see EN 14140 or an equivalent standard); welded aluminium LPG cylinders (see EN 13110 or an equivalent standard); composite LPG cylinders (see EN 14427 or an equivalent standard). Specific requirements for different types of
29、 cylinders are detailed in Annex A, Annex B, Annex C and Annex D. NOTE Rejection limits for a particular type of protected cylinder are 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 cylin
30、der populations. 2 Normative references The following referenced documents are indispensable for the application of this document. For dated references, only the edition cited applies.

34、sified in accordance with UN number 1965, hydrocarbon gases mixture, liquefied, NOS or UN number 1075, petroleum gases, liquefied NOTE In some countries, UN numbers 1011 and 1978 may also be designated LPG. 3.2 competent person person who by a combination of training, experience and supervision, is
35、able to make objective judgements on the subject 3.3 competent body person or corporate body defined by the national authority, which by combination of appropriate qualification, training, experience and resources is able to make objective judgements on the subject 3.4 cylinder transportable, refill
36、able pressure receptacle with a water capacity from 0,5 l up to and including 150 l 3.5 protected cylinder metallic cylinder fully covered with a protection against impact and external corrosion so that the cylinder wall cannot be seen NOTE This is not a composite cylinder; see EN 14427 and Figure G
37、.1 3.6 casing permanently attached sleeve covering part of or the whole of the pressure containing envelope of a composite cylinder, usually incorporating a foot ring and a shroud NOTE Permanently attached means that casing cannot be removed during service without destruction, or by using special to
38、ols. 3.7 filling ratio ratio of the mass of gas introduced into a cylinder to the mass of water at 15 C that would fill the same cylinder fitted ready for use NOTE See Annex E for filling ratios. 3.8 reference temperature temperature used for the calculation of safe filling quantity NOTE See Annex E

A flow diagram of the checks before,
43、 during and after filling is given in Annex F. 4.2 Cylinders suitable for filling The cylinder shall be deemed suitable for filling if the following conditions apply: a) design code/specification is identifiable; b) tare indication and water capacity are known or marked; c) allowed quantity and iden
44、tification of the product (butane, propane or mixtures thereof, the properties of which were considered for the design of the 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
45、described in 4.4. For metallic cylinders, the inspection of the foot-ring for corrosion or damage shall determine the need for 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.
