14、:2000. EN 61969-1:2012 includes the following significant technical changes with respect to EN 61969-1:2000: a) Addition of design guidance for thermal management and noise suppression as thermal/noise management is often considered a basic requirement of an empty outdoor enclosure. If thermal manag

15、ement components are included in the product, the environmental impact may become the responsibility of the empty outdoor enclosure manufacturer. Therefore the acoustic limitations shall be observed. Typically, the user of the empty outdoor enclosure follows the local regulatory acoustic requirement

16、s (sound power and/or sound pressure). Acoustic measurements may be performed on the empty outdoor enclosure fitted with thermal management components only or, if agreed between manufacturer and user at the final stage of the application specific installation. b) Historically, EN 61969-1:2000 intend

17、ed to create a market for standardized empty outdoor enclosures offered by multiple vendors. Detail standards such as EN 61969-2-1:2000 and EN 61969-2-2:2000 were issued to guide users to preferred and available solutions. Attention is drawn to the possibility that some of the elements of this docum
