simple pressure vessel s covered by this Technical Regulation presents a risk to the health or safety of 
persons, or to domestic animals or property,  they shall carry out an evaluation in relation to the vessel 
concerned covering all relevant requirements laid down in this Technical Regulation. The relevant economic 
operators shall cooperate as necessary with the market surveillance authorities for that purpose.  
Where, in the course of the evaluation referred to in the first subparagraph, the market surveillance 
authorities find that the vessel does not comply with the requirements laid down in this Technical 
Regulation, they shall without delay inform the Organisation and require the relevant economic operator to 
take all appropriate corrective actions to bring the vessel into compliance with those requirements, to 
withdraw the vessel from the Gulf Common Market , or to recall it within a reasonable peri od, commensurate 
with the nature of the risk, as they may prescribe.  
The market surveillance authorities shall inform the Organisation and the relevant notified body accordingly.

equivalent effectiveness. Convex ends other than hemispherical ones shall have a cylindrical edge.  
2.1.   Wall thickness  
If the product of PS × V is not more than 3 000 bar.L, the manufacturer shall select one of the methods 
described in points 2.1.1 and 2.1.2 for determining vessel wall thickness; if the product of PS × V is more 
than 3 000 bar.L, or if the maximum working temperature exceeds 100 °C, such thickness shall be 
determined by the method described in point 2.1.1.  
The actual wall thickness of the cylindrical section and end s shall, however, be not less than 2 mm in the 
case of steel vessels and not less than 3 mm in the case of aluminium or aluminium alloy vessels.

However, where the cylindrical portion of the vessel has one or more longitudinal welds made using a non -
automatic welding process, the thickness calculat ed as referred to in the first paragraph shall be multiplied 
by the coefficient 1,15.  
2.1.2.   Experimental method  
Wall thickness shall be so determined as to enable the vessels to resist at ambient temperature a pressure 
equal to at least five times the m aximum working pressure, with a permanent circumferential deformation 
factor of no more than 1 %.
