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 populations 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 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.
Protection of the environment is a key 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 appropriately 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.

4 Requirements for periodic inspection
The interval between periodic inspections 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 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 fulfilled 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.
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 unserviceable 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 scrapping.
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. !deleted text"
NOTE 5 Tests can be performed in any order as determined by the written scheme.

5.1 General
Relevant cylinder data shall be identified before any inspections or tests are carried out.
Cylinders which cannot be safely emptied of gas shall be set aside for special handling.
Cylinders with inoperative or blocked valves shall be set aside for safe valve removal.
Before preparing for inspection, manufacturer's guidelines shall be taken into account to avoid any
damage to the cylinders.
Any chemical solutions and/or cleaning methods used shall be selected to ensure that they do not
adversely affect cylinder material.
5.2 External visual inspection
5.2.1 Preparation for external visual inspection
a) If necessary, the cylinder shall be cleaned and have all loose coatings or labels, corrosion products,
tar, oil or other foreign matter removed from its external surface,

b) Care shall be taken to avoid damaging the cylinder.
c) When cylinders are treated by a process that might remove cylinder material, the inspection body
shall decide whether a thickness test is required, e.g. ultrasonic thickness check.
NOTE Cleaning methods include wire brushing, shot blasting (in accordance with EN ISO 8504 ![5]"
series and EN ISO 8501-1 ![4]"), water jet cleaning, chemical cleaning or other suitable methods, that do not
adversely affect any part of the cylinders.
5.2.2 Inspection procedure
LPG cylinders shall be inspected for:
a) dents, cuts, gouges, bulges, cracks, laminations or punctures while applying the criteria for rejection
in Annex A;
b) corrosion, applying the criteria for rejection given in Annex A; while giving special attention to
areas where water can be trapped;
EXAMPLE At the base of the cylinder;
the junction between the cylindrical shell and the foot-ring;
the junction between the cylindrical shell and the valve guard or shroud; and
hidden corrosion (e.g. under handles).
c) other defects (e.g. depressed bung or fire damage) while applying the criteria for rejection given in
Annex A;
d) integrity of all permanent attachments; and
e) integrity of all mandatory permanent markings.
5.2.3 Rejection criteria
The specific requirements for external visual inspection of LPG cylinders are described in Annex A
including defect descriptions and rejection limits.
5.3 Proof pressure test
5.3.1 General
The test shall consist of one of the proof pressure tests described in 5.3.2 and 5.3.3. #deleted text$
The pneumatic proof test as described in 5.3.3 shall only be implemented where such an operation does
not entail any danger.
#NOTE See also ADR, chapter 6.2.1.6.1.$
Pressure gauges that are used to read the cylinder test pressure, shall be in accordance with
EN 837-1:1996 and EN 837-3:1996, accuracy class 1,6 or better. They shall be calibrated or checked for
accuracy against a master gauge at regular intervals and not less frequently than once every six months.
The master gauge shall be re-calibrated in accordance with national requirements.
All joints within the system shall be leak tight.
The test equipment shall not restrict the expansion of the cylinder.

5.3.2 Hydraulic proof pressure test
5.3.2.1 General
A non-corrosive liquid that is compatible with the material of construction of the cylinder shall be used
as the test medium.
5.3.2.2 Preparation of cylinders
a) Cylinders shall be depressurized in a safe and controlled manner before proceeding.
b) The external surface of the cylinder shall be in such a condition that any leak can be detected. If the
cleaning method involves the wetting of the outside surface or if the outside surface is wet due to
outdoor storage conditions, the outside surface shall be completely dried before commencing the
test procedure.
5.3.2.3 Test equipment
The design and installation of the equipment and the cylinders connected to it shall ensure that no air is
trapped in the system.
A device shall be fitted to the test equipment to ensure that no cylinder is subjected to pressure in
excess of its test pressure by more than the tolerance given in 5.3.2.4.
5.3.2.4 Test procedure
a) The cylinder shall be positioned so that the welds are visible during the test.
b) The test pressure for a RID/ADR cylinder shall be at least the test pressure marked on the cylinder.
For non-RID/ADR cylinders see Annex C.
c) The pressure shall be gradually increased in the cylinder until the test pressure is reached.
d) The test pressure shall not be exceeded by more than 20 % or 6 bar, whichever is the least. More
than one cylinder can be tested at a time provided they all have a test pressure within the tolerance
specified. If the cylinder is tested at a higher pressure than that marked, the owner of the cylinder
shall calculate the maximum pressure not to be exceeded to ensure that the general membrane
stress in the cylinder wall does not exceed 90 % of the guaranteed minimum yield strength of the
material used in the finished cylinder.
