16、3306:2010EN 13306:2010 (E) 4 Introduction The purpose of this European Standard is to define the generic terms used for all types of maintenance and maintenance management irrespective of the type of item considered. Maintenance of software only is not covered in this standard. However, maintenance
17、of items and systems containing software is considered. It is the responsibility of any maintenance management to define its maintenance strategy according to the following main objectives: to ensure the availability of the item to function as required, at optimum costs; to consider the safety and a
18、ny other mandatory requirements associated with the item; to consider any impact on the environment; to uphold the durability of the item and/or the quality of the product or service provided considering costs where necessary. As a part of the requirement of CEN/TC 319 it was necessary to produce a
19、comprehensive structured generic maintenance vocabulary standard containing the main terms and their definitions. Maintenance provides an essential contribution to the dependability of an item. Correct and formal definitions are required which will give the user of associated maintenance standards a
20、 fuller understanding of the maintenance terms used. These terms may be of particular importance in the formulation of maintenance contracts. The terms contained in this standard indicate that maintenance is not confined to the technical actions alone but includes other activities such as planning,
21、documentation handling, etc. The standard IEC 60050-191 has been used as a basis for the preparation of this standard but some terms have been modified. Not all terms specified in IEC 60050-191 are included in this European Standard. Readers are referred to this IEC standard for further definitions.
22、 BS EN 13306:2010EN 13306:2010 (E) 5 1 Scope This European Standard specifies generic terms and definitions for the technical, administrative and managerial areas of maintenance. It may not be applicable to terms which are used for the maintenance of software only. 2 Fundamental terms 2.1 maintenanc
23、e combination of all technical, administrative and managerial actions during the life cycle of an item intended to retain it in, or restore it to, a state in which it can perform the required function NOTE See also the definitions of improvement and modification. 2.2 maintenance management all activ
24、ities of the management that determine the maintenance objectives, strategies and responsibilities, and implementation of them by such means as maintenance planning, maintenance control, and the improvement of maintenance activities and economics 2.3 maintenance objective target assigned and accepte
25、d for the maintenance activities NOTE These targets may include for example availability, cost reduction, product quality, environment preservation, safety, asset value preservation. 2.4 maintenance strategy management method used in order to achieve the maintenance objectives NOTE Examples could be
26、 outsourcing of maintenance, allocation of resources, etc. 2.5 maintenance plan structured and documented set of tasks that include the activities, procedures, resources and the time scale required to carry out maintenance 2.6 required function function, combination of functions, or a total combinat
27、ion of functions of an item which are considered necessary to provide a given service NOTE 1 To provide a given service may also include asset value preservation. NOTE 2 The given service may be expressed or implied and may in some cases be below the original design specifications. 2.7 dependability
28、 ability to perform as and when required NOTE 1 Dependability characteristics include availability and its influencing factors (reliability, recoverability, maintainability, maintenance support performance) and, in some cases, durability, economics, integrity, safety, security and conditions of use.
29、 BS EN 13306:2010EN 13306:2010 (E) 6 NOTE 2 Dependability is used descriptively as an umbrella term for the time-related quality characteristics of a product or service. 2.8 maintenance supportability maintenance support performance ability of a maintenance organization to have the correct maintenan
30、ce support at the necessary place to perform the required maintenance activity when required 2.9 operation combination of all technical, administrative and managerial actions, other than maintenance actions, that results in the item being in use NOTE Maintenance actions carried out by operators are
31、not included in operation. 3 Item related terms 3.1 item part, component, device, subsystem, functional unit, equipment or system that can be individually described and considered NOTE 1 A number of items e.g. a population of items, or a sample, may itself be considered as an item. NOTE 2 An item ma
32、y consist of hardware, software or both. NOTE 3 Software consists of programs, procedures, rules, documentation and data of an information processing system. 3.2 asset (physical) item formally accountable 3.3 repairable item item which may be restored under given conditions, and after a failure to a
33、 state in which it can perform a required function NOTE The given conditions may be economical, ecological, technical and/or others. 3.4 consumable item item or material which is expendable, may be regularly replaced and generally is not item specific NOTE Generally, consumable items are relatively
34、low cost compared to the item itself. 3.5 spare part item intended to replace a corresponding item in order to retain or maintain the original required function of the item NOTE 1 The original item may be subsequently repaired. NOTE 2 In English, any item that is dedicated and/or exchangeable for a
35、specific item is often referred to as replacement item. BS EN 13306:2010EN 13306:2010 (E) 7 3.6 insurance spare part spare part which is not normally needed during the useful life of the item but whose unavailability would involve an unacceptable downtime due to its provisioning NOTE If the spare pa
36、rt is expensive then for accountancy purposes such a part may be considered as a capital asset. 3.7 indenture level level of sub-division within an item hierarchy NOTE 1 Examples of indenture levels are: system, subsystem and component. NOTE 2 From the maintenance perspective, the indenture level de
37、pends on the complexity of the items construction, the accessibility to sub-items, skill level of maintenance personnel, test equipment facilities, safety considerations, etc. 4 Properties of items 4.1 availability ability to be in a state to perform as and when required, under given conditions, ass
38、uming that the necessary external resources are provided NOTE 1 This ability depends on the combined aspects of the reliability, maintainability and recoverability of the item and the maintenance supportability. NOTE 2 Required external resources, other than maintenance resources, do not affect the
39、availability of the item although the item may not be available from the users viewpoint. NOTE 3 Availability may be quantified using appropriate measures or indicators and is then referred to as availability performance. 4.2 reliability ability of an item to perform a required function under given
40、conditions for a given time interval NOTE 1 It is assumed that the item is in a state to performed as required at the beginning of the time interval. NOTE 2 Reliability may be quantified as a probability or performance indicators by using appropriate measures and is then referred to as reliability p
41、erformance. NOTE 3 In some cases a given number of unit of use can be considered instead of a given time interval (number of cycles, number of running hours, number of kilometres, etc.). 4.3 intrinsic reliability inherent reliability reliability of an item determined by design and manufacture 4.4 ma
42、intainability ability of an item under given conditions of use, to be retained in, or restored to, a state in which it can perform a required function, when maintenance is performed under given conditions and using stated procedures and resources NOTE Maintainability may be quantified using appropri
43、ate measures or indicators and is then referred to as maintainability performance. BS EN 13306:2010EN 13306:2010 (E) 8 4.5 intrinsic maintainability inherent maintainability maintainability of an item determined by the original design 4.6 conformity fulfilment of a requirement 4.7 durability ability
44、 of an item to perform a required function under given conditions of use and maintenance, until a limiting state is reached NOTE 1 A limiting state of an item may be characterized by the end of the useful life. NOTE 2 The limiting state may be redefined by changes in conditions of use. 4.8 redundanc
45、y in an item, existence of more than one means for performing a required function when needed 4.9 active redundancy redundancy wherein more than one means for performing a required function are operating simultaneously 4.10 standby redundancy redundancy wherein an alternative means for performing th
46、e particular function is only activated when the active means is unavailable NOTE Standby redundancy is often referred to as passive redundancy 4.11 useful life time interval from a given instant until the instant when a limiting state is reached NOTE The limiting state may be a function of failure
47、rate, maintenance support requirement, physical condition, economics, age, obsolescence, changes in the users requirements or other relevant factors. 4.12 mean failure rate number of failures of an item in a given time interval divided by the time interval NOTE In some cases unit of time can be repl
48、aced by units of use. 4.13 life cycle series of stages through which an item goes, from its conception to disposal 4.14 obsolescence (for maintenance purposes) inability of an item to be maintained due to the unavailability on the market of the necessary resources at acceptable technical and/or econ
49、omic conditions NOTE 1 The necessary resources can be: one (or more) sub-item needed to restore the item; BS EN 13306:2010EN 13306:2010 (E) 9 tools or monitoring or testing devices; documentary resources; skills; etc. NOTE 2 The unavailability of the resources can be due to: technological development; market situation; absence of supplier; regulations. 5 Failures and events 5.1 failure termination of the ability of an item to perform a required function NOTE 1 After failure the item
