This  International  Standard  specifies  a  method  for measuring  the  sound  pressure  levels  on  a  measure- ment  surface  enveloping  the  source  in  order  to  cal- culate  the  sound  power  level  produced  by  the  noise source.  It gives  requirements  for  the  test  environment and  instrumentation  as  well  as  techniques  for  obtain- ing  the  surface  sound  pressure  level  from  which  the sound  power  level  of  the  source  is  calculated,  leading to  results  which  have  a grade  3  accuracy. It  is  important  that  specific  noise  test  codes  for  vari- ous  types  of  equipment  be  established  and  used  in accordance  with  this  International  Standard.  For  each type  of  equipment,  such  noise  test  codes  will  give detailed  requirements  on  mounting,  loading  and  op- erating  conditions  for  the  equipment  under  test  as well  as  a  selection  of  the  measurement  surface  and the  microphone  array  as  specified  in  this  International Standard.
