To comply with PED, you cannot use ASME Part D material properties in Div. By doing so, these designs are more likely to be compliant with PED directives. In order to design compliant designs in European markets, designers will want to reference both PD 5500 and EN 13445. However, PED Annex I: Essential Safety Requirements does specify the following limits: The Pressure Equipment Directive and the Designerįrom a design perspective, the PED regulations only affect areas such as material certification, testing, etc. Furthermore, ASME VIII Div.2 was re-written in 2007 in part to address these issues and to remain competitive in the European markets. However, in most cases, the PED regulation requirements could be met if some relatively inexpensive measures were taken. There were doubts about the suitability of the ASME VIII fatigue design in regard to European safety philosophy.

In general, pressure equipment designed according to the ASME VIII code alone was not compliant with the safety requirements of the PED. The Pressure Equipment Directive and the Design Codes PD 5500Īnnex Z Guidance on the application of PD 5500 to pressure vessels falling within the scope of the European Pressure Equipment Directive details how PD 5500 complies with the PED regulations. have added appendices to show how they comply with PED’s essential safety requirements. Meanwhile, all major codes, such as ASME VIII, PD 5500, CODAP, etc. Designers creating pressure vessels or heat exchangers for European markets must be familiar with the Pressure Equipment Directive (PED).įirst published in 1997, the PED regulations are an instrument of law, not a design code, and it details the essential safety requirements that pressure equipment must meet.ĮN 13445, released in 2002, gives an automatic assumption of conformity with the essential safety requirements of the PED.
