The informative Annex C gives information on technical delivery conditions for clad products. Annex D gives an informative survey on European base material and component standards and their systematic nomenclature.
Rules are also given for components subjectto local loads and. These formulae are generaily intended for predominantly non-cyclic loads, which means for a number of full pressure cycles not exceeding However general prescriptions are also given for DBA Design by Analysis which can be used either to evaluate component designs or loading situations for which a DBF method is not provided, or, more generally, as an alternative to DBF.
Methods are also given where a fatigue evaluation is required, due to a number of load cycles being greater than There are two alternative methods: a simplified method based on DBF valid only in case of pressure variations and a more sophisticated method based on a detailed determination of total stresses using, for example, FEM or experimental methods. This can be used also in the case of variable loads other than pressure.
For certain components such as flanges and tubesheets also an alternative DBF method based on limit analysis has been provided; the choice of which method has to be used in each particular case is lett to the Designer. For the time being, the scope of Part 3 is limited to steel components working at temperatures lower than the creep vange of the specific material concerned.
Part 4 is not applicable for Part 6 which has separate and different requirements regarding manufacturing. Part 5 This Part covers all those inspection and testing activities associated with the verification of the pressure vessel for compliance with the standard. Inspection activities include design review by the manufacturer and supporting technical documentation..
Numerous inspection activities, in addition to the Non Destructive Testing NOT are described including document control, material traceability, joint preparation and welding. The requirements for testing are predominantly related to individually designed single vessels.
However, Annex A provides a procedure for serially produced pressure vessels. Basically, the testing group determines the level of NOT and the joint coefficient used in the design. There are four testing groups which are designed to give the same safety by a combination of several factors.
Testing groups take into consideration manufacturing difficulties associated with different groups of steels, maximum permitted thickness, welding processes, service temperature range and the thickness by means of the joint coefficient of the governing joint. However, it was necessary to subdivide testing groups 1, 2 and 3 into subgroups 1 a, 1 b, 2a, 2b, 3a, and 3b in order to reflect the better behaviour to crack sensitivity of easy to weld steels of groups 1.
A single testing group is normally applied to the entire vessel. However, provided specific requirements are met, a combination of testing groups is permitted.
Appropriate formulae are given in order that the stresses be limited to safe values. These formulae are generally intended for predominantly static loads, which means for a number of load cycles not exceeding in the case of spheroidal graphite cast iron. Calculation of minimum wall thickness is dealt with by Part 3 except for design stresses which are given in Part 6.
A method for design by experiment up to 6 bar-l without calculation is given.

Learn how.For serially produced pressure vessels an alternative route is given in Annex A. This European Standard applies to unfired pressure "sse Is subject to a maximum allowable pressure greater than 0,5 bar gauge but may be used for vessels Jerating at lower pressures, including vacuum. Basically, the testing group determines the level of NOT and the joint coefficient used in the design. The pressure shall be maintained at the speciied close examination level or a suicient length o time to permit a visual inspection to be made o all suraces and joints.
