The work of prep
24、aring International Standards is normally carried out through ISO technical committees. Each member body interested in a subject for which a technical committee has been established has the right to be represented on that committee. International organizations, governmental and non-governmental, in
25、liaison with ISO, also take part in the work. ISO collaborates closely with the International Electrotechnical Commission (IEC) on all matters of electrotechnical standardization.The procedures used to develop this document and those intended for its further maintenance are described in the ISO/IEC
26、Directives, Part 1. In particular the different approval criteria needed for the different types of ISO documents should be noted.

ISO 2013 All rights reserved vBS EN ISO 11011:2015 EN ISO 11011:2015 (E)IntroductionThis International Standard has been developed with reference to available documentation1)(see Bibliography) relating to energy assessment of compressed air systems.This Interna
30、tional Standard is produced to support the objectives of energy management for those organisations utilizing compressed air and wishing to improve the energy efficiency of such systems. Remembering the words of Lord Kelvin who said in 1883, “If you cannot measure it, you cannot improve it”, this Int
31、ernational Standard aims to assist with measurement and provide the knowledge to enable improvement.The prime consideration for any compressed air system is the ability to generate air with the least amount of energy. Having done this, the next consideration is to transmit energy from the point of g
32、eneration to the point of use with the least loss. The final consideration is to eliminate waste and use the least amount of air for the production process.This International Standard uses speciality terms which relate the needs of assessment activities to those of compressed air systems. Many terms
33、 will appear new to the users of this International Standard who are familiar with general compressed air terms.A general introduction to energy assessment is given in Annex A.1) Extracts from ASME EA-4-2010 were used with permission from ASME. The core elements used are from Scope and Introduction,

35、rnational Standard are advised that energy-related judgements should not compromise safety issues.1 ScopeThis International Standard sets requirements for conducting and reporting the results of a compressed air system assessment (hereafter referenced as an “assessment”) that considers the entire sy
36、stem, from energy inputs to the work performed as the result of these inputs.This International Standard considers compressed air systems as three functional subsystems: supply which includes the conversion of primary energy resource to compressed air energy; transmission which includes movement of
37、compressed air energy from where it is generated to where it is used; demand which includes the total of all compressed air consumers, including productive end-use applications and various forms of compressed air waste.This International Standard sets requirements for analysing the data from the ass
38、essment, reporting and documentation of assessment findings, and identification of an estimate of energy saving resulting from the assessment process.This International Standard identifies the roles and responsibilities of those involved in the assessment activity.This International Standard provide
39、s indicative information in Annexes B, C, D, and E of the type of data to be collected to assist in a successful assessment. The information provided is not exhaustive and therefore is not intended to restrict the inclusion of other data. The form and presentation of the information given in the ann
40、exes is also not intended to restrict the manner of presentation of the reporting to the client.2 Normative referencesThe following documents, in whole or in part, are normatively referenced in this document and are indispensable for its application.
