Performance of enclosures and cabins designed for noise control are dealt with in this standard. Outlining the acoustical and operational requirements which are to be agreed upon between the supplier and manufacturer and the user of such cabins and enclosures. Applicable to two types of acoustic enclosures and cabins, as follows: Free-standing enclosures covering or housing machines; cabins for noise protection of operators: free standing cabins and cabins attached to machines (e.g. vehicles, cranes); enclosures with a fraction of acoustically untreated open area of less than 10% of the total surface are the main subjects. Not applicable to partial enclosures or integrated enclosures. Emphasis is put on lightweight construction, however, thick massive structures (brick walls etc) are not included.
