36、small machine enclos- Ures. lt applies to a total enclosure only and not to the in- dividual Panels from which the enclosure is made. NOTES 1 Sound insulation for enclosure Panels such as wall el- ements, doors, windows, silencers, etc. should be measured in accordance with other relevant Standards.
37、 2 Related Standards concern noise-attenuation measure- ments of enclosures in sjtu (ISO 11546-2) and cabins (ISO 11957). The measurement methods specified in this part of ISO 11546 are based on International Standards in the series ISO 3740, ISO 9614 and ISO 11200 (see table 1). Depending on the me
38、thod Chosen, the Sound insulation Performance (insertion loss) of the enclos- ure is determined in terms of the reduction of Sound power level or Sound pressure level. Methods are given for measurements where the enclosure sur- rounds the actual Sound Source (machine). Where these methods are not pr
39、acticable, alternative measurements tan be performed using a reciprocity method (see definition 3.11 and subclause 7.2) or an artificial Sound Source. This part of ISO 11546 is applicable without any re- strictions to freestanding enclosures with volumes less than 2 m3. If the actual Sound Source is
40、 used, the Sound insulation Performance of enclosures with vol- umes exceeding. 2 m3 tan be determined provided that the requirements concerning maximum permiss- ible volume in the Standard used are fulfilled. The ac- tual Sound Source method is applicable for any kind of enclosure design, for examp
41、le enclosures fixed to the machine. When the reciprocity method or the artificial Sound Source method is used, the maximum volume of the enclosure is limited to 2 m3. These methods are not applicable to close-fitting enclosures. The wording “laboratory conditions” used in the title of this part of I
42、SO 11546 indicates that test conditions and test environment (indoor or outdoor) fully conform to the respective International Standards given in table 1. 2 Normative references The following Standards contain provisions which, through reference in this text, constitute provisions of this part of IS
43、O 11546. At the time of publication, the editions indicated were valid. All Standards are subject to revision, and Parties to agreements based on this part of ISO 11546 are encouraged to investi- gate the possibility of applying the most recent edi- tions of the Standards indicated below.
