Guideline G-17
Reason:Impact property values are the most common way to fulfil the essential safety requirement of toughness specified in Annex I Section 4.1a. Although impact testing of materials is the commonly accepted route to demonstrate materials have specified minimum toughness, it is not the only route.EXAMPLES: Restrictions on operating temperatures, Fracture mechanics. Note 1:Every harmonized European […]
Guideline G-18
They apply to the pressure equipment in its entirety, i.e. also to the heat affected zones of a weldment, but not to the non pressure-bearing parts. Note:Subsequent manufacturing processes affecting properties of the base material shall be taken into account when specifying the properties of the base material, as per Annex I, sections 3.1.1, 3.1.2 […]
Guideline G-19
To be incorporated into an item of pressure equipment, components which are manufactured from materials such as plates, coils and bars shall meet all the relevant essential safety requirements related to the manufacturing process used ; for instance in the manufacturing of welded dished ends, sections 3.1 and 7.2 of Annex I are relevant in […]
Guideline G-22
Other criteria in Annex I Section 7.5 refers to further criteria depending e.g. on the type/dimension/product form and resistance level of steel or mode of operation, which shall be taken into account to prove its toughness and ductility. Other values in Annex I Section 7.5 refers to those other criteria which can result in more […]
