1、DRAFT FOR DEVELOPMENT DD CEN/TS 764-6:2004 Pressure equipment Part 6: Structure and content of operating instructions ICS 23.020.30 ? DD CEN/TS 764-6:2004 This Draft for Development was published under the authority of the Standards Policy and Strategy Committee on 19 August 2004 BSI 19 August 2004
2、ISBN 0 580 44305 1 National foreword This Draft for Development is the official English language version of CEN/TS 764-6:2004. This publication is not to be regarded as a British Standard. It is being issued in the Draft for Development series of publications and is of a provisional nature because i
3、t was subject to criticisms from other CEN technical committee other than CEN/TC 54 who drafted it. The EN 764 series of standards are horizontal standards that cover all pressure equipment but CEN/TS 764-6 was written mainly on the basis of Unfired Pressure Vessels. A joint working group of CEN/TC
4、54 and CEN/TC 267 has now been created so that CEN/TS 764-6 can be amended to better cover pressure vessels and piping assemblies. In the meantime CEN/TS 764-6 should be applied on a provisional basis (for pressure vessels only), so that information and experience of its practical application may be
5、 obtained. Comments arising from the use of this Draft for Development are requested so that UK experience can be reported to the European organization responsible for its conversion to a European Standard. A review of this publication will be initiated 2 years after its publication by the European
6、organization so that a decision can be taken on its status at the end of its 3-year life. Notification of the start of the review period will be made in an announcement in the appropriate issue of Update Standards. According to the replies received by the end of the review period, the responsible BS
7、I Committee will decide whether to support the conversion into a European Standard, to extend the life of the Technical Specification or to withdraw it. Comments should be sent in writing to the Secretary of BSI Technical Committee PVE/1, Pressure Vessels, at British Standards House, 389 Chiswick Hi
8、gh Road, London W4 4AL, giving the document reference and clause number and proposing, where possible, an appropriate revision of the text. A list of organizations represented on this committee can be obtained on request to its secretary. Cross-references The British Standards which implement intern
9、ational or European publications referred to in this document may be found in the BSI Catalogue under the section entitled “International Standards Correspondence Index”, or by using the “Search” facility of the BSI Electronic Catalogue or of British Standards Online.

12、nd Inhalt einer Betriebsanleitung This Technical Specification (CEN/TS) was approved by CEN on 30 April 2004 for provisional application. The period of validity of this CEN/TS is limited initially to three years. After two years the members of CEN will be requested to submit their comments, particul
13、arly on the question whether the CEN/TS can be converted into a European Standard. CEN members are required to announce the existence of this CEN/TS in the same way as for an EN and to make the CEN/TS available promptly at national level in an appropriate form. It is permissible to keep conflicting
14、national standards in force (in parallel to the CEN/TS) until the final decision about the possible conversion of the CEN/TS into an EN is reached. CEN members are the national standards bodies of Austria, Belgium, Cyprus, Czech Republic, Denmark, Estonia, Finland, France, Germany, Greece, Hungary,

CEN/TS 764-6:2004 (E) 4 1 Scope This part six of this document identifies the requirements for operating instructions which accompany the pressure equipment when it is placed
24、on the market. Operating instructions shall contain the necessary safety information covering installation including assembling, putting into service and maintenance. 2 General The manufacturer shall identify and analyse all known and foreseeable hazards in the intended use and clearly foreseeable m
25、isuse which could occur in mounting, putting into service, use, maintenance and in ser- vice inspections by the user of the pressure equipment. The possible hazards which could not be eliminated in the design of the product or by secondary safety devices are treated in Clause 3 of this document. The
26、se are residual hazards which can occur when a vessel is installed and used or operated under foreseeable conditions. Where appropriate, residual hazards shall be covered under the operating instructions given by the manufacturer. Operating instructions shall cover information marked on the pressure
27、 equipment and where appropriate, be supported by technical documents, drawings and diagrams for a full understanding of these operating instruc- tions. 3 Hazard analysis 3.1 General The hazard analysis shall enable the manufacturer to identify and to determine the potential modes of failure due to
28、loading of pressure equipment which could occur when this equipment is installed and used in reason- able foreseeable conditions. Given below in 3.2 and 3.3 are hazards or combinations of hazards which need to be considered for operat- ing instructions. This list is not intended to be fully comprehe
29、nsive but illustrative of the scope of information which needs to be taken into account. 3.2 Possible hazards for all pressure equipment and assemblies Hazardous situations during operations are: a) exceeding of internal or external maximum allowable pressure; b) exceeding of maximum or minimum allo
30、wable temperature or temperature gradients; c) exceeding of features of design relevant to the life of equipment covering creep, fatigue and corrosion; d) hazards by static pressure and mass contents in operating and test conditions; e) exceeding of traffic-, wind-, snow-, earthquake- and dynamic-lo
31、ading; f) exceeding of reaction forces and moments which result from supports, attachments, piping etc.; g) decomposition of unstable fluids; h) instability aspects; i) incorrect handling of closures and openings; CEN/TS 764-6:2004 (E) 5 j) dangerous discharge of pressure relief blow-off; k) incorre
32、ct handling of devices to prevent physical access whilst pressure or a vacuum exists; l) surface temperature taking into consideration the intended use; m) incorrect handling of unstable fluids resulting in decomposition; n) incorrect draining and venting with the following possible consequences: 1)
33、 water hammer, vacuum collapse, corrosion and chemical reactions; 2) inhibition of safe cleaning, inspection and maintenance in a safe manner; o) failing of protection against corrosion or inadequate allowance of chemical attack of the materials; p) excess wear; q) incorrect assembly of components;
34、r) incorrect filling and discharge, e.g.: 1) overfilling or overpressurisation; 2) instability of the pressure equipment; 3) uncontrolled release of the pressurised fluid; 4) unsafe connection and disconnection; s) inadequate failure of safety accessories, pressure limiting- and temperature monitori
35、ng devices, e.g. with regard to: 1) reliability for the intended duty; 2) maintenance and test requirements; 3) independence from functions; t) inadequate failure of provisions for external fire. Potential for clearly foreseeable misuse which can not be eliminated by design shall be clearly identifi
36、ed by a visible warning and shall be described in the operating instructions. 3.3 Possible hazards for specific pressure equipment and assemblies 3.3.1 Fired or otherwise treated pressure equipment and assemblies A failure of protection against significant loss of containment from overheating covers
37、, but is not limited to: a) lack of operating parameters for heat input, heat take-off and where appropriate fluid level; b) defective sampling points to allow evaluation of fluid properties to avoid risk related to deposits and for corrosion; c) failure of provisions to eliminate risks of damage fr
38、om deposits and the safe removal of residual heat after shut-down; d) failure of provisions to prevent a dangerous accumulation of ignitable mixtures of combustible substances and air or flame blow back. CEN/TS 764-6:2004 (E) 6 3.3.2 Piping NOTE Any reference to piping has been withdrawn from this T
39、S 764-6:200X. CEN/TC 54 intends to amend this document as a Type 1 European Standard EN 764 Part 6 in a Joint Working Group together with CEN/TC 267 “Industrial piping and pipelines“ and CEN/TC 269 “Shell and water tube boilers“ (Resolution CEN/TC 54 no. 2003/427). 4 Content of operating instruction
