28、ssure 64 PTB-10-2015: Guide for ASME Section VIII Div 1 Stamp Holders 1 FOREWORD This Guide is a comprehensive review of the Pressure Equipment Directive (PED) and ASME Section VIII, Division 1. ASME has received requests from all over the world to provide guidance to manufacturers who have been or

29、will be impacted by the European PED. This document provides that guidance. Established in 1880, the American Society of Mechanical Engineers (ASME) is a professional not-for-profit organization with more than 135,000 members and volunteers promoting the art, science, and practice of mechanical and

30、multidisciplinary engineering and allied sciences. ASME develops codes and standards that enhance public safety, and provides lifelong learning and technical exchange opportunities benefiting the engineering and technology community. Visit www.asme.org for more information. Manufacturers of Section

31、VIII pressure vessels will find this document to be a useful tool when working with a notified body toward compliance with the PED and applying the CE mark to their products. This document begins with an explanation of the European New Approach and continues with the goals of the PED and a descripti

32、on of its scope of coverage. Then, the document offers an in-depth analysis of the PED concept of hazard categories and the various combinations of conformity assessment modules that can be used for each hazard category. Each of the PED Essential Safety Requirements are then covered, including mater

33、ials, use of Notified Bodies, and requirements for CE marking. The reader is presented next with a detailed comparison of the PED with Section VIII, Division 1, followed by a modified version of Annex Z for Section VIII, Division 1. This Annex Z provides instructions regarding what additional tasks

34、must be completed to meet the administrative requirements of the PED. PTB-10-2015: Guide for ASME Section VIII Div 1 Stamp Holders 2 1 INTRODUCTION When the EC Pressure Equipment Directive (PED) 97/23/CE was adopted in May 1997, it became clear that pressure equipment designed and built to standards

35、 other than European standards could carry the CE mark. This was made possible by the European New Approach, in which Essential Safety Requirements (ESR) are established in the Directives, and standards are used to support them. The PED 97/23/CE has now been substantially amended and replaced by Dir

36、ective 2014/68/EU, issued 15 May 2014. The new PED shall be applied no later than July 19, 2016, except that Article 13 shall be applied from June 1, 2015. The purpose of this ASME PED Guide is to provide analysis of the PED and compare its ESR with the design, construction, and administrative requi

37、rements of ASME Section VIII, Division 1. The PED Guide is composed of three major portions. The first portion consists of Chapters I through X, which gives an overview of the PED, provides important basic information on the entire Directive, and identifies specific issues of higher importance. The

38、next major portion is Chapters XI and XII, which provides a comparison of the PED and Section VIII, Division 1 requirements, including commentary on both, and an Annex Z for Section VIII, Division 1. Annex Z provides Section VIII Code users with instructions on how to augment their current practices

39、 to meet all ESRs of the PED. The third portion of this Guide gives a listing of approved CLAP interpretation sheets. It is intent that this Guide will form the basis for an understanding between manufacturers and Notified Bodies regarding the use of ASME Section VIII, Division 1 as the basis for co

40、mpliance with the PED. Having such a uniform approach will benefit not only manufacturers and Notified Bodies, but also users of pressure equipment. Several PED Information Resource Center websites provide the latest information on the status of European approval of materials, names, contact informa

41、tion for all Notified Bodies, and other valuable news and developments. These are: http:/ec.europa.eu/enterprise/sectors/pressure-and-gas/documents/ped/index_en.htm http:/ec.europa.eu/growth/single-market/european-standards/harmonised-standards/pressure-equipment/index_en.htm http:/ec.europa.eu/ente

42、rprise/newapproach/nando/index.cfm?fuseaction=directive.notifiedbody however, it has the benefit of the free movement throughout the EU. 5.3 Equipment in Hazard Categories I to IV (Article 4-1 of the PED) Equipment that is above the thresholds defined in Article 4-3 of the PED is classified in Hazar

43、d Category I to IV, depending on their level of hazard. This Equipment (a) is subject to ESR (b) is subject to the Conformity Assessment Procedure (c) is subject to the Declaration of Conformity (d) must bear the CE Marking PTB-10-2015: Guide for ASME Section VIII Div 1 Stamp Holders 10 (e) has free

44、 movement throughout the EU. Hazard categories depend on the following factors. (a) Type of Equipment: Vessel (fired on unfired), Piping, Safety Accessory, Pressure Accessory. (b) Nature of Fluid: (1) Gas in the sense of the PED (Article 4-l.l(a) of the PED): gas, liquefied gas, gas dissolved under

45、pressure, vapors, etc. (2) Liquid in the sense of the PED (Article 4-l.l(b) of the PED): liquids having a vapor pressure 0.5 bar. Figure 5-1: Hazard Category for Vessel Containing a Dangerous Gas Note: Refer To Table 1 of the PED (c) Dangerousness of the fluid, which is classified into two groups (A

46、rticle 13-1(a) of the PED): (1) Group 1: Dangerous fluids (explosives, flammable, toxic, oxidizing, pyrophoric). (2) Group 2: Non-dangerous fluids (all others). (d) Operations conditions characterized by the maximum allowable pressure, PS, and the internal volume, V (for Vessels), or the nominal dia

47、meter, DN (for Piping). The hazard categories are defined in the PED by graphs (Tables 1 through 9 of Annex II of the PED). How to determine the hazard category is explained as follows for each type of Equipment. PTB-10-2015: Guide for ASME Section VIII Div 1 Stamp Holders 11 5.4 Vessels Not Subject

48、 to Fire or Heat (Article 4-1(a) of the PED) Figure 4-1 enables the determination of the Hazard Category of a vessel “not fired, nor heated with a risk of overheating” containing a dangerous gas, as a function of internal volume, V, and maximum allowable pressure, PS. NOTE: If the vessel is composed

49、 of several chambers, the determination of the Hazard Category must be performed for each chamber and the higher hazard category is to be used. The volume, V, to be used is the total internal volume of the vessel or the chamber (not the volume occupied by the fluid). Each demarcation line pertains to the lower hazard category. Three additional graphs, given by Tables 2, 3, and 4 of the PED (Annex II), cover vessels containing a (a) Non-dangerous gas (Table 2) (b) dangerous liquid (Table 3) (c) non-dangerous liquid (Table 4). 5.5 Vessels Subject to Fire or He
