13、ort and as such is a generic document that identifies requirements for operating instructions which accompany the pressure equipment when it is placed on the marked. It only provides general statements and thus does not claim to give presumption of conformity to the essential safety requirements of

14、the Pressure Equipment Directive 97/23/EC (PED). Operating instructions contain the necessary safety information covering installation including assembling, putting into service and maintenance. For specific items of pressure equipment or assemblies, more detailed requirements on the content of oper

15、ating instructions can be found in specific standard series such as EN 13445 “Unfired pressure vessels”, EN 13480 “Industrial piping”, EN 12952 “Water-tube boilers and auxil-iary installations”, or EN 12953 “Shell boilers”. 2 General The manufacturer needs to identify and analyse all known and fores

16、eeable hazards in the intended use and clearly foreseeable misuse which may occur in mounting, putting into service, use, maintenance and in-service inspections by the user of the pressure equipment. Possible hazards which could not be eliminated in the design of the product or by secondary safety d

17、evices are treated in Clause 3 of this document. These are residual hazards which can occur when a vessel is in-stalled and used or operated under foreseeable conditions. Where appropriate, residual hazards are dealt with in the operating instructions given by the manufacturer. Operating instruction

18、s cover the information marked on the pressure equipment and are, where appropriate, supported by technical documents, drawings and diagrams for a full understanding. Depending on the type of pressure equipment a) a manufacturer may decide to put constraints on the use of the pressure equipment, e.g

19、. in the case of series products or “catalogue” products, or b) a user/client may, e.g. via project specifications, put constraints on the design or the manufacture of the pressure equipment. In each of these cases, the constraints specified by the manufacturer (as in a) or the solutions specified b

20、y the client (as in b) are identified in the operating instructions. 3 Hazard analysis 3.1 General It is the purpose of the hazard analysis to enable the manufacturer to identify and determine the potential modes of failure due to loading of the actual piece of pressure equipment which could occur w

21、hen this equip-ment is installed and used in reasonably foreseeable conditions. Given below in 3.2 and 3.3 are hazards or combinations of hazards which need to be considered for operating instructions. This list is not intended to be fully comprehensive, but illustrative of the scope of information

22、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; PD CEN/TR 764-6:2012CEN/TR 764-6:2012 (E) 5 b) exceeding of maximum or minimum allowable t

23、emperature 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-loading;

24、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; j) dangerous discharge of pressure relief blow-off; k) incorrect handling of devices to preve

25、nt 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) water hammer, vacuum collapse,

26、 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; r) incorrect filling and discha

27、rge, 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 monitoring devices, e.g. with regard to

28、: 1) reliability for the intended duty; 2) maintenance and test requirements; 3) independence from functions; t) inadequate failure of provisions for external fire. It is important that potential for clearly foreseeable misuse which cannot be eliminated by design is clearly identified by a visible w

29、arning and is described in the operating instructions. PD CEN/TR 764-6:2012CEN/TR 764-6:2012 (E) 6 3.3 Fired or otherwise heated pressure equipment and assemblies Failure of protection against significant loss of containment from overheating includes, but is not limited to: a) lack of operating para

30、meters 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 from deposits and the safe removal of residual hea

31、t after shut-down; d) failure of provisions to prevent a dangerous accumulation of ignitable mixtures of combustible substances and air or flame blow back. 4 Content of operating instructions 4.1 General 4.1.1 Introduction When pressure equipment is placed on the market, the manufacturer is required

32、 to ensure that it is accompa-nied by instructions for the user containing safety information. Additional information may be requested by the user or recommended by the manufacturer, and agreed as part of the order or contract. Regarding general information about the pressure equipment, operating in

33、structions contain all important safety information that is applicable to the equipment. The information given to the user of the equipment in-cludes, but is not limited to, the following: 4.1.2 Information on the data plate a) Mandatory information: 1) name and address or other means of identificat

34、ion of the manufacturer and, where appropriate, of his authorised representative established within the Community; 2) year of manufacture; 3) identification of the pressure equipment according to its nature, such as type, series or batch identi-fication and serial number; 4) essential maximum/minimu

35、m allowable limits (normally PS, TSmaxand TSmin). This information under Clause 4.1.2 a) is mandatory for pressure equipment that has to fulfil the Essential Safety Requirements of the PED. b) Depending on the type of pressure equipment, further information may be necessary for safe installation, op

36、eration or use and, where applicable, maintenance and periodic inspection such as: 1) volume V of the pressure equipment, in litres (l); 2) nominal size for piping, DN; 3) test pressure (PT) applied, in bar, and the date; PD CEN/TR 764-6:2012CEN/TR 764-6:2012 (E) 7 4) safety device set pressure, in

37、bar; 5) output of the pressure equipment, in kW; 6) supply voltage, in V (volts); 7) intended use; 8) filling ratio, in kg/l; 9) maximum filling mass, in kg; 10) tare mass, in kg; 11) fluid group. 12) name of the fluid in case the equipment is designed for a specific fluid only. 4.1.3 Information in

38、 operating instructions On all occasions where warnings are fixed to the pressure equipment these are identified in the operating in-structions. The operating instructions cover all information marked on the pressure equipment and contain, as far as appropriate, information on: a) safe operating lim

39、its and design basis, including anticipated operating and assumed design conditions; b) design standard(s); c) joint coefficients; d) the estimated lifetime, taking account of fatigue, creep, corrosion, and wear; e) features of the design relevant to the life of the equipment; f) residual hazards no

40、t prevented by design or protective measures that might arise from foreseeable mis-use; g) list of typical spares; h) replaceable parts. Where necessary, the operating instructions may also contain technical documents, drawings and diagrams necessary for a full understanding of these instructions. I

41、n the case of an assembly under the PED, it is important that the accompanying operating instructions con-tain a description of all items of pressure equipment constituting the assembly. Such a description includes the identification of the items of pressure equipment falling under Category I to IV

42、as well as the other items taken into account in the integration of the PED assembly, i.e. equipment falling under Art. 3(3) of the PED (without CE-mark, only the sound engineering practice of a Member State) or pressure equipment explicitly excluded from the scope of the PED. The declaration of con

43、formity is a helpful document to the distributor or user because it is a summary of de-sign, manufacture and conformity assessment. Therefore, although it may not be explicitly required by the PED that an EC declaration of conformity be supplied together with pressure equipment bearing a CE-mark, it

44、 PD CEN/TR 764-6:2012CEN/TR 764-6:2012 (E) 8 is strongly recommended to provide the EC declaration of conformity for all products which are intended to be put into service as such, together with the product. The EC declaration of conformity may be included in the instructions for use. Other informat

45、ion may be included by contractual agreement, such as hazard analysis, material certificates, detailed design calculations, “as built”-drawings, heat treatment records, welding records, NDT results, results of dimensional check, full records of proof test, details and results of special checks, deta

46、ils of any corrective repair or modifications, full documentation of any concessions made. 4.2 Transportation and erection or installation (mounting) It is important that the operating instructions contain all necessary information for the transportation and erec-tion of the pressure equipment. This

47、 includes, but is not limited to, the following: a) storage and transport aspects; b) possible variations in erection/transport of assembly (supported by technical drawings and calculations if necessary); c) necessary distance to other objects; d) relevant information for design of the grounding (e.

48、g. support forces etc.). 4.3 Putting into service It is important that the operating instructions provide necessary information to put pressure equipment safely into service. This includes, but is not limited to, the following: a) removal of existing transportation protection etc.; b) details on ope

49、rating fluids and start up quantities; c) additional safety requirements associated with commissioning or start up. 4.4 Use/Operation It is important that the operating instructions contain all necessary information for the safe use of the pressure equipment with special reference to prevent potential misuse of the equipment. The operating instructions in-clude the issues identified in the hazard analysis which could not be eliminated. It is important that any special measures necessary to reduce operation risks are described and that these measures
