EN 13648-2:2002 (E)3ForewordThis document (EN 13648-2:2002) has been prepared by Technical Committee CEN/TC 268 "Cryogenic vessels",the secretariat of which is held by AFNOR.This European Standard shall be given the status of a national standard, either by publication of an identical text orby endorsement, at the latest by November 2002, and conflicting national standards shall be withdrawn at the latestby November 2002.This document has been prepared under a mandate given to CEN by the European Commission and the EuropeanFree Trade Association, and supports essential requirements of EU Directive(s).For relationship with EU Directive(s), see informative annex ZA, which is an integral part of this document.This document also supports the objectives of the framework Directives on Transport of Dangerous Goods. Thisstandard has been submitted for reference into the RID and/or the technical annexes of the ADR.This European Standard is composed of the following Parts :EN 13648-1, Cryogenic vessels – Safety devices for protection against excessive pressure – Part 1 : Safety valvesfor cryogenic service ;EN 13648-2, Cryogenic vessels – Safety devices for protection against excessive pressure – Part 2 : Bursting discssafety devices for cryogenic service ;prEN 13648-3, Cryogenic vessels – Safety devices for protection against excessive pressure – Part 3 :Determination of required discharge - Capacity and sizing.According to the CEN/CENELEC Internal Regulations, the national standards organizations of the followingcountries are bound to implement this European Standard: Austria, Belgium, Czech Republic, Denmark, Finland,France, Germany, Greece, Iceland, Ireland, Italy, Luxembourg, Malta, Netherlands, Norway, Portugal, Spain,Sweden, Switzerland and the United Kingdom.SIST EN 13648-2:2002



EN 13648-2:2002 (E)41 ScopeThis European Standard specifies the requirements for the design, manufacture and testing of bursting disc safetydevices for cryogenic service, i.e. for operation with cryogenic fluids below – 10 °C in addition to operation atambient temperature. It is a requirement of this standard that the bursting disc safety device(s) complywith prEN ISO 4126-2. In the event of different requirements, this standard takes precedence over that standard.This standard is restricted to bursting disc safety devices not exceeding a size of DN 100 designed to relieve singlephase vapours or gases. A bursting disc assembly can be specified, constructed and tested such that it is suitablefor
use with more than one gas or with mixtures of gases.NOTEThis standard does not provide methods for determining the capacity of bursting disc safety devices for a particularcryogenic vessel. Such methods are provided in prEN 13648-3.2 Normative referencesThis European Standard incorporates, by dated or undated reference, provisions from other publications.
