4 SCOPE (ARTICLES 1, 2, AND 4 OF THE PED) 4.1 Scope (Article 1-§1 of the PED) The PED embraces all Pressure Equipment subject to an internal pressure of gas or fluid above 0.5 bar. It applies to new Equipment fabricated in the EU (and to new or used Equipment imported from countries outside the EU). In-service inspection of operating Equipment is covered in the national regulations of each EU country. (It is not intended to develop an EU Directive covering in-service inspection.) All materials, metallic and nonmetallic, are considered. This scope is very wide as it covers any pressure containment above 0.5 bar from simple pressure- cookers to large water-tube boilers.
4.2 Types of Equipment Covered (Article 2 and Article 4 of the PED) In the PED, the term Pressure Equipment covers the four following types. vessel: a component intended to contain a fluid (gas or liquid) above 0.5 bar. This covers what was formerly called pressure vessels (unfired or fired). piping: a component intended for the transport of fluids. safety accessories: devices designed to protect the Equipment. pressure accessories: devices with an operational function and subject to pressure (such as valves, pressure regulators, pressure gauges, filters, expansion joints, etc.). Components (such as covers, collars, gaskets, flanges, bolts, and nozzles) are not considered as pressure accessories and cannot bear the CE Marking. PED covers also Assemblies made of several parts of Pressure Equipment, assembled by the Manufacturer to constitute an integrated and functional whole, such as boilers. These Assemblies are mentioned several times throughout the PED and are covered in Appendix H of this Guide. Only the above four types of Pressure Equipment (plus Assemblies) can bear the CE Marking and have the free movement throughout EU. Equipment subject to 0.5 bar, or less, are not regulated by the PED, as they do not present a significant hazard.
9 NOTIFIED BODIES (CHAPTER 4 OF THE PED) (a) The PED provides for the involvement of an NB to assess the conformity of the Equipment to the specifications of the PED. (b) These NBs shall comply with various requirements in terms of technical competence, organization, independence, etc. (See PED, Article 24). They are designated by the official authorities of each Member State, who notify the references of these bodies to the Commission of the European Communities. The Commission publishes the list of the NB in the OJEC. (c) The Manufacturer may select any of the NB from this list. (d) According to the PED, the approval of joint procedures, joint operators (particularly welders) and non- destructive testing operators may, in some cases, be performed by Recognized Third-Party Organizations (PED Article 20). These entities shall comply with criteria similar to those of the NB.ASME PTB-10 pdf download.
