1、Designation: D7841 13Standard Practice forSustainable Laundry Best Management Practices1This standard is issued under the fixed designation D7841; the number immediately following the designation indicates the year oforiginal adoption or, in the case of revision, the year of last revision. A number
2、in parentheses indicates the year of last reapproval. Asuperscript epsilon () indicates an editorial change since the last revision or reapproval.1. Scope1.1 PurposeThe purpose of this practice is to identify anddefine sustainable laundry Best Management Practices (BMPs)that are used in commercial l
3、aundry facilities to reduce theirimpact on the environment.1.2 It is recommended that users rely on professionaljudgment informed by both environmental expertise and spe-cific knowledge of the intended use of this practice. Thispractice provides instruction on interpretation of the dataobtained. Int
4、erpretation of the data results in a determination ofwhether a laundry implements enough BMPs to be certified ascomplying with the requirements of this practice.1.3 The users of this practice include laundry professionalsand inspectors who possess a broad understanding of environ-mental issues relat
5、ed to the operations and maintenance oflaundry facilities.1.4 The values stated in SI units are to be regarded asstandard. No other units of measurement are included in thisstandard.1.5 This standard does not purport to address all of thesafety concerns, if any, associated with its use. It is theres
6、ponsibility 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.
