14、:2011ivForewordISO (the International Organization for Standardization) is a worldwide federation of national standards bodies (ISOmember bodies). The work of preparing International Standards is normally carried out through ISO technicalcommittees. Each member body interested in a subject for which

15、 a technical committee has been established hasthe right to be represented on that committee. International organizations, governmental and non-governmental, inliaison with ISO, also take part in the work. ISO collaborates closely with the International ElectrotechnicalCommission (IEC) on all matter

16、s of electrotechnical standardization.International Standards are drafted in accordance with the rules given in the ISO/IEC Directives, Part 3.The main task of technical committees is to prepare International Standards. Draft International Standards adoptedby the technical committees are circulated

17、to the member bodies for voting. Publication as an InternationalStandard requires approval by at least 75 % of the member bodies casting a vote.In exceptional circumstances, when a technical committee has collected data of a different kind from that which isnormally published as an International Sta

18、ndard (“state of the art“, for example), it may decide by a simple majorityvote of its participating members to publish a Technical Report. A Technical Report is entirely informative in natureand does not have to be reviewed until the data it provides are considered to be no longer valid or useful.A

20、ructures forpetroleum and natural gas industries.PD CEN ISO/TR 13881:2011dvIntroductionWhen a user/purchaser wishes to procure a product, process or service, the user/purchaser may produce afunctional specification (see ISO 13879). If so, the manufacturer/supplier provides a technical specification

21、(seeISO 13880) as the basis for manufacturing or execution. The user/purchaser decides on the extent to which it isnecessary to determine, directly or indirectly, that relevant requirements are fulfilled and states this in the contractwith the manufacturer/supplier.This document describes:Gbe two me

22、thodologies which enable the required degree of assurance to be determined by classification, which inturn dictates the conformity assessment system;Gbe a set of five conformity assessment systems which when applied can give an increasing level of confidencethat the product, process or service confo

28、l Report, the terms and definitions of conformity-assessment-related terms givenin ISO/IEC Guide 2 apply, with the exception of the terms defined below.3.1classnumber assigned to a product, process or service, associated with the risk of its failure during use due to design ormanufacturing, process

29、or service errors, that indicates the appropriate conformity assessment system to beadopted1) To be published. (Revision of ISO 9001:1994)PD CEN ISO/TR 13881:20112NOTE The classification of a product, process or service does not take into consideration failure due to misuse or incorrectmaintenance o

30、f the product, process or service.3.2probability of failurefrequency of occurrence of a product, process or service failure happening within one year divided by the totalnumber of the particular products, processes or services in operation during the same year3.3consequence of failureresults of the

31、failure of the product, process or serviceNOTE In the petroleum and natural gas industries, the most commonly used measure of consequence is financial cost. Thisimplies that the intangible aspects of the results following a failure, such as community acceptance, be translated to financialcost. The c

32、ost for failure can comprise cost for restoring the environment (i.e. damage to the environment), deferred or loss ofproduction, reduction in efficiency, health and safety-related cost, etc.3.4risk of failureprobability multiplied by consequence3.5design reviewformal, documented, comprehensive and s

33、ystematic examination of a design to evaluate the design requirementsand the capabilities of the design to meet these requirementsNOTE 1 In the context of the document, the acceptance criteria for the design review are defined in the functional andtechnical specifications (see ISO 13879 and ISO 1388

34、0).NOTE 2 A service is also designed and can be reviewed in the same manner.3.6witness pointpoint in the chain of activities, defined in the quality or inspection plan agreed upon, to be witnessed by theconformity assessment body if deemed necessary3.7hold pointpoint, defined in an appropriate docum

35、ent, beyond which an activity should not proceed without the approval of adesignated organization or authorityNOTE The approval to proceed beyond a hold point is usually given in written form, but it may be given by any other agreedsystem of authorization.4 Classification principlesFor the purposes

36、of this Technical Report, the following classification principles apply.Gbe CLASS should be determined taking full account of the total life of the product, process or service, starting withits functional specification and ending with its decommissioning/demobilization.Gbe CLASS should take full acc

37、ount of the health, safety and environmental requirements valid for the countries inwhich the product, process or service is created, used and/or decommissioned/demobilized.Gbe CLASS, when established according to clause 5 or clause 6, should be determined using verifiableparameters.In this Technica

38、l Report, five classes are defined, from 1 to 5, of which CLASS 1 represents the highest risk offailure and CLASS 5 represents the lowest risk of failure.The relationship between the classes and the conformity assessment systems is defined in Table 1.PD CEN ISO/TR 13881:2011d3CLASS only has a meanin

39、g and/or significance in combination with one of the conformity assessment systemsdefined.Table 1 Class and conformity assessment system relationshipCLASS 1 System ACLASS 2 System BCLASS 3 System CCLASS 4 System DCLASS 5 System EClause 5 and clause 6 provide two different methods of CLASS determinat

40、ion.5 Classification method based on calculation5.1 GeneralThis method can be used when specific data on costs and probabilities are available. Two sub-models arepresented here. When combined, they provide a full model for classification. The sub-models are based on theassumption that cost can be al

41、located to the level of certainty that the product, process or service will fulfil itsintended purpose without failure. Other models may be used but are not described within this Technical Report.NOTE The classification models are used by the user/purchaser of a product, process or service to calcul

42、ate and thereafterindicate which CLASS number is required to obtain the appropriate conformity assessment. The CLASS is related to the risk offailure during use of a product, process and/or service.5.2 Explanation of the factors used in the sub-modelsThe sub-models are built on the following premise

43、s:Gbe every activity bears risks which can be translated into cost;Gbe the models are applicable to the design and manufacture as well as the operational life of the product, processor service.The risks are connected with failures whereby the operational cost during the life is determined by in situ

44、maintenance, periodic inspection, required level of spare parts, etc.NOTE The risk of failure can be reduced by, for example, more frequent inspections or supervisory actions, a thoroughmaintenance process, a better controlled manufacturing/service process, etc.5.3 Risk-related sub-modelTr=(p0Gd7 c0

45、)+(p1Gd7 c1)+(p2Gd7 c2) 1whereTris the total risk, in monetary terms;p0is the probability of failure of the product, process or service during use, due to design;c0is the consequence of design-related failure;p1is the probability of failure of the product, process or service during use, due to manuf

46、acturing of productor execution of services/processes;PD CEN ISO/TR 13881:20114c1is the consequence of manufacturing/execution-related failure;p2is the probability of failure of the product, process or service during use, for other reasons such asabsence of proper instructions, etc.;c2is the consequ

47、ence of failure related to other reasons.The probability of failure can be obtained from historical data, preferably from a public database. In any case, arecord should be kept of where the probability data was obtained.Furthermore, for the purposes of this Technical Report, the probability factors

48、have to be correlated to both theconformity assessment system which was adopted when producing the product or executing the service orprocess, and the verification of performance during the life cycle.5.4 Integrity-related sub-modelTv= Cv+ Cc2whereTvis the total cost for verification;Cvis the planne

49、d cost for verifications during the life of the product, process or service per year;Ccis the cost of obtaining a product, process or service using the conformity assessment system on the basisof which the probability factors have been derived.NOTE 1 Increasing the in situ verifications of products, processes or services will reduce the probability of failure becausefailures are generally not incidents which happen suddenly but are preceded by a deterioration of the products performance orservice, process execution.NOTE 2 These increased verifications w
