New pressure receptacles, other than closed cryogenic receptacles and metal hydride storage
systems,
shall be subjected to testing and inspection during and after manufacture in accordance with the
applicable design standards including the following:
On an adequate sample of pressure receptacles:
(a) Testing of the mechanical characteristics of the material of construction;
(b) Verification of the minimum wall thickness;
(c) Verification of the homogeneity of the material for each manufacturing batch;
(d) Inspection of the external and internal conditions of the pressure receptacles;
(e) Inspection of the neck threads;
(f) Verification of the conformance with the design standard; For all pressure receptacles:
(g) A hydraulic pressure test. Pressure receptacles shall meet the acceptance criteria
specified in the design and construction technical standard or technical code;
NOTE: With the agreement of the competent authority, the hydraulic pressure test may be
replaced by a test using a gas, where such an operation does not entail any danger.
(h) Inspection and assessment of manufacturing defects and either repairing them or rendering
the pressure receptacles unserviceable. In the case of welded pressure receptacles, particular
attention shall be paid to the quality of the welds;
(i) An inspection of the marks on the pressure receptacles;
(j) In addition, pressure receptacles intended for the carriage of UN No. 1001 acetylene,
dissolved, and UN No. 3374 acetylene, solvent free, shall be inspected to ensure proper
installation and condition of the porous material and, if applicable, the quantity of solvent.
On an adequate sample of closed cryogenic receptacles, the inspections and tests specified in
6.2.1.5.1
(a), (b), (d) and (f) shall be performed. In addition, welds shall be inspected by radiographic,
ultrasonic or another suitable non-destructive test method on a sample of closed cryogenic
receptacles according to the applicable design and construction standard. This weld inspection does
not apply to the jacket.
Additionally, all closed cryogenic receptacles shall undergo the initial inspections and tests
specified in 6.2.1.5.1 (g), (h) and (i), as well as a leakproofness test and a test of the
satisfactory operation of the
service equipment after assembly.
For metal hydride storage systems, it shall be verified that the inspections and tests specified in
6.2.1.5.1 (a), (b), (c), (d), (e) if applicable, (f), (g), (h) and (i) have been performed on an adequate
sample of the receptacles used in the metal hydride storage system. In addition, on an adequate sample
of metal hydride storage systems, the inspections and tests specified in 6.2.1.5.1 (c) and (f) shall be
performed, as well as 6.2.1.5.1 (e), if applicable, and inspection of the external conditions of the metal
hydride storage system.
Additionally, all metal hydride storage systems shall undergo the initial inspections and tests specified
in 6.2.1.5.1 (h) and (i), as well as a leakproofness test and a test of the satisfactory operation of the
service equipment.
Periodic inspection and test
Refillable pressure receptacles, other than cryogenic receptacles, shall be subjected to periodic
inspections and tests by a body authorised by the competent authority, in accordance with the
following:
(a) Check of the external conditions of the pressure receptacle and verification of the equipment
and the external marks;
(b) Check of the internal conditions of the pressure receptacle (e.g. internal inspection,
verification of minimum wall thickness);
(c) Checking of the threads if there is evidence of corrosion or if the fittings are removed;
(d) A hydraulic pressure test and, if necessary, verification of the characteristics of the material
by suitable tests;
(e) Check of service equipment, other accessories and pressure-relief devices, if to be
reintroduced into service.
NOTE 1: With the agreement of the competent authority, the hydraulic pressure test may be
replaced by a test using a gas, where such an operation does not entail any danger.
NOTE 2: With the agreement of the competent authority, the hydraulic pressure test of cylinders
or tubes may be replaced by an equivalent method based on acoustic emission testing or a
combination of acoustic emission testing and ultrasonic examination. ISO 16148:2006 may be used as
a guide for acoustic emission testing procedures.
NOTE 3: The hydraulic pressure test may be replaced by ultrasonic examination carried out in
accordance with ISO 10461:2005+A1:2006 for seamless aluminium alloy gas cylinders and in
accordance with ISO 6406:2005 for seamless steel gas cylinders.
NOTE 4: For the periodic inspection and test frequencies, see packing instruction P200 of 4.1.4.1
or, for a chemical under pressure, packing instruction P206 of 4.1.4.1.
Pressure receptacles intended for the carriage of UN No. 1001 acetylene, dissolved and UN No. 3374
acetylene, solvent free, shall be examined only as specified in 6.2.1.6.1 (a), (c) and (e). In addition the
condition of the porous material (e.g. cracks, top clearance, loosening, settlement) shall be examined.
Pressure relief valves for closed cryogenic receptacles shall be subject to periodic inspections and
tests.
Requirements for manufacturers
The manufacturer shall be technically able and shall possess all resources required for the satisfactory
manufacture of pressure receptacles; this relates in particular to qualified personnel:
(a) To supervise the entire manufacturing process;
(b) To carry out joining of materials; and
(c) To carry out the relevant tests.
The proficiency test of a manufacturer shall in all instances be carried out by an inspection body
approved by the competent authority of the country of approval.
Requirements for inspection bodies
Inspection bodies shall be independent from manufacturing enterprises and competent to perform the
tests, inspections and approvals required.
Requirements for UN pressure receptacles
In addition to the general requirements of section 6.2.1, UN pressure receptacles shall comply with the
requirements of this section, including the standards, as applicable. Manufacture of new pressure
receptacles or service equipment according to any particular standard in 6.2.2.1 and 6.2.2.3 is not
permitted after the date shown in the right hand column of the tables.
NOTE 1: UN pressure receptacles and service equipment constructed according to standards
applicable at the date of manufacture may continue in use subject to the periodic inspection
provisions of ADR.
NOTE2: When EN ISO versions of the following ISO standards are available, they may be used
to fulfil the requirements of 6.2.2.1, 6.2.2.2, 6.2.2.3 and 6.2.2.4.
Design, construction and initial inspection and test
The following standards apply for the design, construction, and initial inspection and test of
UN cylinders, except that inspection requirements related to the conformity assessment system and
approval shall be in accordance with 6.2.2.5:
