The provisions of packing instruction P200 (10), special packing provision v of 4.1.4.1 applicable
until 31 December 2010 may be applied by Contracting Parties to ADR to cylinders constructed
before 1 January 2015.
Refillable welded steel cylinders for the carriage of gases of UN Nos. 1011, 1075, 1965, 1969 or
1978, granted 15 year intervals for periodic inspection in accordance with packing instruction P200
(10), special packing provision v of 4.1.4.1 as applicable until 31 December 2010 by the competent
authority of the country (countries) of carriage, may continue to be periodically inspected according to
those provisions.
Gas cartridges constructed and prepared for carriage before 1 January 2013 for which the
requirements of 1.8.6, 1.8.7 or 1.8.8 for the conformity assessment of gas cartridges have not been
applied may still be carried after this date, provided all the other applicable provisions of ADR are
met.
Salvage pressure receptacles may continue to be constructed and approved according to national
regulations up to 31 December 2013. Salvage pressure receptacles constructed and approved in
accordance with national regulations before 1 January 2014 may continue to be used with the approval
of the competent authorities of the countries of use.
Bundles of cylinders manufactured before 1 July 2013 which are not marked in accordance with
6.2.3.9.7.2 and 6.2.3.9.7.3 applicable from 1 January 2013 or 6.2.3.9.7.2 applicable from 1 January
2015 may be used until the next periodic inspection after 1 July 2015.
Cylinders constructed before 1 January 2016 in accordance with 6.2.3 and a specification approved by
the competent authorities of the countries of transport and use, but not in accordance with ISO
11513:2011 or ISO 9809-1:2010 as required in 4.1.4.1, packing instruction P208 (1), may be used for

Fixed tanks (tank-vehicles), demountable tanks and battery-vehicles
Fixed tanks (tank-vehicles), demountable tanks and battery-vehicles built before the entry into force
of the requirements applicable as from 1 October 1978 may be kept in service if the equipment of the
shell meets the requirements of Chapter 6.8. The thickness of the shell wall, except in the case of
shells intended for the carriage of refrigerated liquefied gases of Class 2, shall be appropriate to a
calculation pressure of not less than 0.4 MPa (4 bar) (gauge pressure) in the case of mild steel or of
not less than 200 kPa (2 bar) (gauge pressure) in the case of aluminium and aluminium alloys. For
other than circular cross-sections of tanks, the diameter to be used as a basis for calculation shall be
that of a circle whose area is equal to that of the actual cross-section of the tank.
The periodic tests for fixed tanks (tank-vehicles), demountable tanks and battery-vehicles kept in
service under these transitional requirements shall be conducted in accordance with the requirements
of 6.8.2.4 and 6.8.3.4 and with the pertinent special requirements for the various classes. Unless the
earlier requirements prescribed a higher test pressure, a test pressure of 200 kPa (2 bar) (gauge
pressure) shall suffice for aluminium shells and aluminium alloy shells.
