Scope1.1 This practice covers standardizing practices and terminology related to information conveying the physical location ofassets.1
3、.2 This practice describes ten increasingly specific levels of asset physical location information, assigning a standard name andlevel number to each.1.3 There is no existing, recognized practice for recording, discussing, and comparing physical location information.1.3 This practice is designed to
4、be applicable and appropriate for all asset-holding entities.1.4 In addition to applicability to assets, this practice may in whole or in part be effectively applied to intangible property, realproperty, and materiel.material.1.5 This standard does not purport to address all of the safety concerns,
5、if any, associated with its use. It is the responsibilityof the user of this standard to establish appropriate safety safety, health, and healthenvironmental practices and determine theapplicability of regulatory limitations prior to use.1.6 This international standard was developed in accordance wi

26、s required or applicable.6.1 This practice does not require that all levels be used in a given each situation.6.1.1 The required specificity shall be determined and recorded. recorded by the entity. This may be done for all assets or forspecific subsets of assets. For example, one companyentity in a
27、n office environment may determine that assets will be tracked toPLL 8, LL 8, room/post/station/area location. Another,Another similar companyentity may determine that assets will be trackedto PLL 6, LL 6, building location.6.1.2 The required generalitylevel of information recorded and communicated
28、will depend on transactional requirements andthe location profile of the entity and shall be determined and specified. For example, if all of a companys assets are located inone building, information for PLL 5 and below for each asset may not be recorded, but may be added as general information when
29、required.specified The applied level should be used consistently throughout the entitys asset management system.5.3.3 Intermediate levels not applicable to a given situation shall be determined and specified. For example, an entity may notrequire use of PLL 8, room/post/station/area location, as PLL
30、 9, desk/shelf location, within PLL 7, floor location, may adequatelyand appropriately convey the physical location information.6.2 An entity shall use the physical location terminology or numerical level references, or both, to assure requirements andresults related to location control are uniforml
31、y expressed and communicated.6.3 An entity shall determine the appropriate level of physical location information to maintain and support the mission of theentity cost effectively.6.3.1 Procedures shall be identified such as timely changes to location when assets are reassigned or relocated or the a
32、bility tolocate assets within a specified period.6.4 It is recognized that other location tracking and recording mechanisms not based in whole or in part on physical locationinformation may be appropriately used in conjunction with or separately from this practice. For example, information technolog
33、ymay be used to determine the logical location of assets connected to a network. This logical location information may or may notbe correlated to physical location information for thisan asset. The functional location of assets within a level of physical locationinformation may be used. For example,
34、 an asset may be recorded with PLL 6, LL 6, building physical location information, andthen listed with a functional location as a part of a parent system such as an air conditioning system.6.5 Spatial tracking systems represent points on the earth numerically.data can be obtained through spatial tr
35、acking systems.Where spatial tracking is used, the precision of the numerical representation may be correlated to the level of granularityLLexpressed in this practice.7.
