USA The ASME Boiler and Pressure Vessel Code is not a law but construction standard generally accepted in USA and in many other countries. The manufacturer may follow any set of rules or standards for design and manufacturing on condition that the Essential Safety Requirements are met. To follow the harmonized standards is the preferred method to show compliance to the PED but they are not mandatory. Pressure Equipment which conform to the harmonized standards is presumed to conform to the Essential Safety Requirements of PED. 10 subsections) IV Rules for Construction of Heating Boilers V Nondestructive Examination VI Recommended Rules for the Care and Operation of Heating Boilers VII Recommended Guidelines for the Care of Power Boilers VIII Rules for Construction of Pressure Vessels Division 1 Division 2 Alternative Rules Division 3 Alternative Rules for Construction of High Pressure Vessels IX Welding and Brazing Qualifications X Fiber-Reinforced Plastic Pressure Vessels XI Rules for Inservice Inspection of Nuclear Power Plant Components XII Rules for Construction and Continued Service of Transport Tanks 5Ħ Differences between European and American legal systems concerning pressure equipment Europe The PED (Pressure Equipment Directive) is the law for all European Union member states The Essential Safety Requirements of PED are often rather general but some requirements are very specific and those specific requirements shall be met. The following are excluded from the scope of this Directive: items specifically designed for nuclear use, failure of which may cause an emission of radioactivity Such equipment should be designed and manufactured in accordance with a specific code like ASME Boiler and Pressure Vessel Code Section III French RCC-M German KTA 3Ĥ Nuclear island Many pressure equipment critical to nuclear safety Conventional island Equipment subject to PED 4ĥ ASME Boiler & Pressure Vessel Code is an extensive set of rules on the design, manufacturing and operation of boilers and pressure vessels I Rules for Construction of Power Boilers II Materials Part A Ferrous Material Specifications Part B Nonferrous Material Specifications Part C Specifications for Welding Rods, Electrodes, and Filler Metals Part D Properties III Rules for Construction of Nuclear Facility Components ( incl.
