Introduction
This European Standard has been prepared to reflect the current state of the art for periodically inspecting
LPG cylinders, and is based upon the operating experience of millions of cylinder years of service over a
period of more than 50 years.
The primary objective of the periodic inspection of transportable refillable LPG cylinders is that, at the
completion of the tests, the cylinder can be re-introduced into service for a further period of time.
The valve inspection is an integral part of the periodic inspection of an LPG cylinder.
Periodic inspection is normally carried out at a test station operated under the responsibility of a competent
gas organisation, or of a third party.
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 t
