The leakproofness test shall be performed in accordance with a procedure which is capable of
indicating leakages in the containment system with a sensitivity of 0.1 Pa.l/s (10-6 bar.l/s).
The water capacity of the packagings shall be established with an accuracy of ± 0.25% at a reference
temperature of 15 °C. The volume shall be stated on the plate described in 188.8.131.52.
A plate made of non-corroding metal shall be durably attached to every packaging in a readily
accessible place. The method of attaching the plate must not impair the strength of the packaging.
The following particulars, at least, shall be marked on the plate by stamping or by any other
- Approval number;
- Manufacturer's serial number;
- Maximum working pressure (gauge pressure);
- Test pressure (gauge pressure);
- Contents: uranium hexafluoride;
- Capacity in litres;
- Maximum permissible filling mass of uranium hexafluoride;
- Tare mass;
- Date (month, year) of the initial test and the most recent periodic test;
- Stamp of the expert who performed the tests.
Approvals of package designs and materials
The approval of designs for packages containing 0.1 kg or more of uranium hexafluoride requires that:
(a) Each design that meets the requirements of 184.108.40.206 shall require multilateral approval;
(b) Each design that meets the requirements of 220.127.116.11 to 18.104.22.168 shall require unilateral approval
by the competent authority of the country of origin of the design, unless multilateral approval is
otherwise required by ADR.
Each Type B(U) and Type C package design shall require unilateral approval, except that:
(a) A package design for fissile material, which is also subject to 22.214.171.124, 126.96.36.199, and 188.8.131.52.1
shall require multilateral approval; and
(b) A Type B(U) package design for low dispersible radioactive material shall require multilateral
Each Type B(M) package design, including those for fissile material which are also subject to the
requirements of 184.108.40.206, 220.127.116.11, and 18.104.22.168.1 and those for low dispersible radioactive material,
shall require multilateral approval.
Each package design for fissile material which is not excepted by any of the paragraphs 22.214.171.124.3.5 (a)
to (f), 126.96.36.199 and 188.8.131.52 shall require multilateral approval.
The design for special form radioactive material shall require unilateral approval. The design for low
dispersible radioactive material shall require multilateral approval (see also 184.108.40.206).
The design for a fissile material excepted from "FISSILE" classification in accordance with
220.127.116.11.3.5 (f) shall require multilateral approval.
Alternative activity limits for an exempt consignment of instruments or articles in accordance with
18.104.22.168.2.2 (b) shall require multilateral approval.
Any design that requires unilateral approval originating in a country Contracting Party to ADR shall
be approved by the competent authority of this country; if the country where the package design has
been designed is not a Contracting Party to ADR, carriage is possible on condition that:
(a) A certificate has been supplied by this country, proving that the package design satisfies the
technical requirements of ADR, and that this certificate is validated by a competent authority
of an ADR Contracting Party;
(b) If no certificate and no existing package design approval by a country Contracting Party to
ADR has been supplied, the package design is approved by the competent authority of an ADR
For designs approved under the transitional measures see 1.6.6.
