EN 1440:2008+A1:2012 (E) 5 Introduction The primary objective of the periodic inspection of transportable refillable liquefied petroleum gas (LPG) cylinders is that, at the completion of the tests, the cylinders can be re-introduced into service for a further period of time. The very large populations of traditional steel LPG cylinders in use have led to the development of alternative methods of inspection. This European Standard has !deleted text" been prepared to reflect the current state of the art for period inspecting of LPG cylinders, and is based on the operating experience of many hundreds of millions of cylinder years of service. 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 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 appropriately 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 !European Standard" is a combination of EN 1440:2005, with EN 14767:2005, EN 14795:2005 and EN 14914:2005. SIST EN 1440:2008+A1:2012

This !European 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 the equivalent standard); welded steel LPG cylinders !manufactured to an alternative design and construction" (see EN 14140:2003+A1 or the equivalent standard); !NOTE This European Standard also applies to protected cylinders, see 5.3 and Annex G." welded aluminium LPG cylinders (see EN 13110 or the equivalent standard); composite LPG cylinders (see EN 14427 or the equivalent standard). 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. This !European Standard" does not apply to cylinders permanently installed in vehicles. 2 Normative references The following referenced documents are indispensable for the application of this European Standard.
