Foreword
This document (EN 14427:2004/A1:2005) has been prepared by Technical Committee CEN/TC 286 “Liquefied
petroleum gas equipment and accessories”, the secretariat of which is held by NSAI.
This Amendment to the European Standard EN 14427:2004 shall be given the status of a national standard,
either by publication of an identical text or by endorsement, at the latest by June 2006, and conflicting national
standards shall be withdrawn at the latest by June 2006.
According to the CEN/CENELEC Internal Regulations, the national standards organizations of the following
countries are bound to implement this European Standard: Austria, Belgium, Cyprus, Czech Republic,
Denmark, Estonia, Finland, France, Germany, Greece, Hungary, Iceland, Ireland, Italy, Latvia, Lithuania,
Luxembourg, Malta, Netherlands, Norway, Poland, Portugal, Slovakia, Slovenia, Spain, Sweden, Switzerland
and United Kingdom.
1 Modification to Clause 2
Add the following reference:
"EN 14763, LPG equipment and accessories – Transportable refillable composite cylinders for Liquefied
Petroleum Gas (LPG) – Procedure for checking before, during and after filling"
2 Modification to Clause 5.1
Add a 1 after NOTE, i.e:
"NOTE 1 Attention is drawn to…."
Add a new note as follows:
"NOTE 2 Reference should also be made to EN 14763, which requires the cylinder manufacturer to perform additional
tests to determine the rejection limits for in-service damage and to include these limits in the documentation for the
cylinder.”
3 Modification to Clause 5.2.9 and Clause 5.2.10
Delete clauses 5.2.9 and 5.2.10 and replace with the following:
"5.2.9 Test No. 9 – Cylinder body integrity impact tests
5.2.9.1 General
The ability of the cylinder design (thickness, materials and mechanical properties) to withstand loadings other
than internal pressure shall be demonstrated by a series of impact tests.
The tests shall be carried out at ambient conditions unless the manufacturer has opted for the alternative test
permitted by 5.2.1.1.1 c), in which case the tests shall be carried out with the cylinders at – 20 °C.
Each type of test shall be carried out on cylinders without internal pressure and cylinders pressurised to 20
bar.
The specified impact energy and striking velocity shall be achieved by striking the test cylinder with a moving
striker or by dropping the cylinder from an appropriate height. In all cases, the location of the impact shall be
as specified in the test procedure and the direction of impact shall intersect with the axis of the cylinder.
The strikers (flat surface and edge) shall be of metallic material having a hardness greater than that of the
cylinder and sufficiently robust to prevent the impact energy being absorbed by deflection of the striker.
