21、 Corrosion protection guidelines .10 EN ISO 15364:2001 ISO 63514:(0002)E iv Foreword ISO (the International Organization for Standardization) is a worldwide federation of national standards bodies (ISO member bodies). The work of preparing International Standards is normally carried out through ISO
22、technical committees. Each member body interested in a subject for which a technical committee has been established has the right to be represented on that committee. International organizations, governmental and non-governmental, in liaison with ISO, also take part in the work. ISO collaborates clo
23、sely with the International Electrotechnical Commission (IEC) on all matters of electrotechnical standardization. International Standards are drafted in accordance with the rules given in the ISO/IEC Directives, Part 3. Draft International Standards adopted by the technical committees are circulated
24、 to the member bodies for voting. Publication as an International Standard requires approval by at least 75 % of the member bodies casting a vote. Attention is drawn to the possibility that some of the elements of this International Standard may be the subject of patent rights. ISO shall not be held
25、 responsible for identifying any or all such patent rights. International Standard ISO 15364 was prepared by Technical Committee ISO/TC 8, Ships and marine technology, Subcommittee SC 3, Piping and machinery. Annex A forms a normative part of this International Standard. Annexes B and C are for info
26、rmation only. EN ISO 15364:2001 INTERNATIONAL STANDADR ISO 46351:(0002)E 1 Ships and marine technology Pressure/vacuum valves for cargo tanks 1 Scope This International Standard applies to pressure/vacuum relief valves protecting marine vessel systems, including cargo tanks, that may be subject to g
27、as/vapour pressure or vacuum outside the design parameters of the system/tank. This standard specifies the minimum requirements for performance and testing of pressure/vacuum relief valves, with emphasis on selection of materials, internal finish and surface requirements for pressure/vacuum valves i
28、nstalled on cargo tanks in tankers (see annex A). This standard specifies design and in-service performance criteria and operational testing and maintenance requirements. This standard does not address devices to prevent the passage of flame. Advice on devices to prevent the passage of flame is foun
29、d in the International Maritime Organization (IMO) “International Convention on the Safety of Life at Sea, 1997” (SOLAS); Chapter II-2, Regulation 59, and IMO Maritime Safety Committee (MSC) Circular No. 677 (MSC/Circ. 677) “Revised Standards for the Design, Testing and Locating of Devices to Preven
30、t the Passage of Flame into Cargo Tanks in Tankers”. 2 Normative references The following normative documents contain provisions which, through reference in this text, constitute provisions of this International Standard. For dated references, subsequent amendments to, or revisions of, any of these
