Unless the product is PS. In more than 3,000 bar.L, the manufacturer shall choose one of the methods set out in paragraphs 2.1.1 and 2.1.2 for determining the thickness of the container wall. If the product is PS. In more than 3,000 bar.L or if the maximum permissible temperature is more than 100 ° C, this thickness shall be determined by the method specified in paragraph 2.1.1.
However, the actual wall thickness of the cylindrical part and the day shall not be less than 2 mm for steel containers and 3 mm for aluminium containers or aluminium alloys.
2.1.1. Calculation method
The minimum thickness of the parts under pressure shall be calculated taking into account the stress intensity and the following provisions:
(a) the calculated calculation pressure shall not be less than the selected maximum permissible pressure PS; and
(b) the permitted total membrane voltage may not exceed the lower of 0,6 RT or 0,3 Rm; for the determination of the permissible voltage the manufacturer shall use the lowest RT and Rm guaranteed by the material manufacturer.
However, if the cylindrical part of the container has one or more longitudinal welds made other than by mechanical means, the thickness calculated as described in the first paragraph shall be multiplied by 1,15.
2.1.2 Experimental method
The wall thickness shall be determined in such a way that, at ambient temperature, the vessels withstand a pressure equal to at least five times the maximum permissible pressure, in which case the permanent circumferential deformation shall not exceed 1%.
3. Production procedures
The containers shall be manufactured and checked in accordance with the requirements set out in points 2, 3 or 4 of Annex 2 to this Regulation.

3.2. Welding joints of pressure-exposed parts
The welds and adjacent areas shall have similar characteristics to the welded materials and shall be free of surface or internal defects likely to endanger the safety of the containers.
Welds shall be made by qualified welders or workers with an appropriate level of competence in accordance with approved welding procedures. Approval and qualification tests shall be carried out by notified bodies.
During production, the manufacturer shall ensure a constant quality of welds by carrying out appropriate tests using appropriate procedures. A report shall be drawn up on these tests.
4. Putting containers into service
The containers shall be accompanied by instructions for use drawn up by the manufacturer as set out in point 2 of Annex 3 to this Regulation.
