BS EN 1440:2016EN 1440:2016 (E) 5 Introduction The primary objective of the periodic inspection of transportable refillable liquefied petroleum gas (LPG) cylinders is that, on completion of the tests, the cylinders can be re-introduced into service for a further period of time. The very large po

26、pulations of traditional steel LPG cylinders in use have led to the development of alternative methods of inspection. This European Standard has been prepared to reflect the current methodology for periodic inspection of LPG cylinders and is based on extensive operating experience. This European Sta

27、ndard 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. Protection of the environment is a key

28、 political issue in Europe and elsewhere, for CEN/TC 286 this is covered in CEN/TS 16765 3, and this Technical Specification should be read in conjunction with this standard. It has been assumed in the drafting of this European Standard that the execution of its provisions is entrusted to appropriat

29、ely qualified and competent persons. Where judgements are called for, it has been assumed that they are made by competent persons who have been specifically trained for the tasks. BS EN 1440:2016EN 1440:2016 (E) 6 1 Scope This European Standard specifies procedures for the periodic inspection and te

30、sting, of transportable refillable LPG cylinders with a water capacity from 0,5 l up to and including 150 l. This European Standard is applicable to welded and brazed steel LPG cylinders with a specified minimum wall thickness designed according to EN 1442, EN 12807, EN 13322-1, or equivalent standa

31、rd (e.g. national codes). This European 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. NOTE The requirements of RID/ADR take precedence over those of this standard in the case of cylinders

32、complying with that regulation, including pi marked cylinders. This European Standard does not apply to cylinders permanently installed in vehicles. 2 Normative references The following documents, in whole or in part, are normatively referenced in this document and are indispensable for its applicat

40、opane, propene, butane, butane isomers, butene with traces of other hydrocarbon gases 3.5 periodic inspection activities carried out at defined intervals, such as examining, measuring, testing or gauging the characteristics of a pressure vessel and comparing these with specified requirements 3.6 tar

42、spections shall be dependent on the content of a written scheme. NOTE 1 A written scheme describes work procedures, criteria, responsibilities and other minimum requirements. The maximum interval between periodic inspections for LPG cylinders shall be 10 years; however it can be extended to 15 years

43、 under the following conditions: for LPG cylinders manufactured before the date 2015-01-01, provided the conditions of Annex B are fully met and approval from the relevant competent authority(ies) has been given; and for RID/ADR welded steel LPG cylinders, provided the requirements of Annex D are fu

44、lfilled and approval from the competent authority has been given. Periodic inspections/tests shall be carried out by a competent person under the authorization of an inspection body based on a written scheme and in accordance with the requirements specified in Table 1.

45、) 8 NOTE 2 RID 1 and ADR 2 include detailed requirements on the qualification, obligations, accreditation and approval of these inspection bodies. Cylinders rejected shall be segregated and shall be either reconditioned, re-tested or rendered unserviceable. The decision to render a cylinder unservic

46、eable can be taken at any stage during the periodic inspection procedure. With agreement by the owner, a cylinder shall be rendered unserviceable in accordance with EN 12816 such that it cannot be re-issued into service as a pressure vessel. NOTE 3 In some countries render unserviceable means scrapp

47、ing. NOTE 4 With the agreement of the competent authority, the proof pressure test of cylinders can be replaced by an equivalent method based on acoustic emission testing, ultrasonic examination or a combination of acoustic emission testing and ultrasonic examination. EN ISO 16148 4 can be used as a

48、 guide for acoustic emission testing procedures. NOTE 5 Tests can be performed in any order as determined by the written scheme.
