It is applicable to the following: — specification of procedures for noise control during engineering of a new plant and modification/extension of existing plants (construction and commissioning noise procedures are outside the scope of this document); — definition of responsibilities of parties involved, viz. “end-user”, “engineering contractor” and “equipment supplier”; — description of general procedures to arrive at noise requirements for individual equipment, based on overall noise requirements for the plant. Input to purchase specifications is presented in Annex A. A schematic flowchart, reviewing the noise control process, is presented in Annex B and a summary of action items is presented in Annex C. An example of an equipment noise data sheet is presented in Annex E.
