1、Designation: E2499 11Standard Practice forClassification of Asset Physical Location Information1This standard is issued under the fixed designation E2499; the number immediately following the designation indicates the year oforiginal adoption or, in the case of revision, the year of last revision. A
2、 number in parentheses indicates the year of last reapproval. Asuperscript epsilon () indicates an editorial change since the last revision or reapproval.1. Scope1.1 This practice covers standardizing practices and termi-nology related to information conveying the physical locationof assets.1.2 This
3、 practice describes ten increasingly specific levelsof asset physical location information, assigning a standardname and level number to each.1.3 There is no existing, recognized practice for recording,discussing, and comparing physical location information.1.4 This practice is designed to be applic
4、able and appropri-ate for all asset-holding entities.1.5 In addition to applicability to assets, this practice may inwhole or in part be effectively applied to intangible property,real property, and materiel.1.6 This standard does not purport to address all of thesafety concerns, if any, associated
5、with its use. It is theresponsibility of the user of this standard to establish appro-priate safety and health practices and determine the applica-bility of regulatory limitations prior to use.2.

Significance and Use3.1 This practice estab
12、lishes a notational and conversationalapproach to asset physical location information to enableprecision in requirements and results related to asset physicallocation tracking.3.2 It is intended that this practice fosters and enablesadditional practices related to or based on asset physicallocation

Asset Physical Location Information Numerical Levels4.1 Space location is physical location level (PLL) 1.4.2 Country location is PLL 2.4.3 State/province location is PLL 3.4.4 City/township/county location is PLL 4.4.5 Site location is PLL 5.4.6 Building location is PLL 6.4.7 Floor l

16、entity shall use the physical location terminology ornumerical level references or both to assure requirements andresults related to location control are uniformly expressed andcommunicated.5.2 An entity shall determine the appropriate level ofphysical location information to maintain and communicat
17、e tosupport the mission of the organization cost effectively.5.2.1 Goals shall be identified such as the ability to locateassets within a specified period of time.5.2.2 Consideration shall be given for the type of buildingsand markings applicable to the site location to determine if anylevel below P
18、LL 5 is required or applicable.5.3 This practice does not require that all levels be used ina given situation.5.3.1 The required specificity shall be determined andrecorded. This may be done for all assets or for specific subsetsof assets. For example, one company in an office environmentmay determi
19、ne that assets will be tracked to PLL 8, room/post/station/area location. Another, similar company may determinethat assets will be tracked to PLL 6, building location.5.3.2 The required generality of information recorded andcommunicated will depend on transactional requirements andthe location prof
20、ile of the entity and shall be determined andspecified. For example, if all of a companys assets are locatedin one building, information for PLL 5 and below for each assetmay not be recorded, but may be added as general informationwhen required.5.3.3 Intermediate levels not applicable to a given sit
21、uationshall be determined and specified. For example, an entity maynot require use of PLL 8, room/post/station/area location, asPLL 9, desk/shelf location, within PLL 7, floor location, mayadequately and appropriately convey the physical locationinformation.5.4 It is recognized that other location t
22、racking and record-ing mechanisms not based in whole or in part on physicallocation information may be appropriately used in conjunctionwith or separately from this practice. For example, informationtechnology may be used to determine the logical location ofassets connected to a network. This logica
23、l location informa-tion may or may not be correlated to physical locationinformation for this asset. The functional location of assetswithin a level of physical location information may be used.For example, an asset may be recorded with PLL 6, buildingphysical location information, and then listed w
24、ith a functionallocation as a part of a parent system such as an air conditioningsystem.5.5 Spatial tracking systems represent points on the earthnumerically. Where spatial tracking is used, the precision of thenumerical representation may be correlated to the level ofgranularity expressed in this p
