Sec. 201.20  Applicability and purpose.


    The following criteria are applicable to and contain the necessary 
parameters and procedures for the measurement of the noise emission 
levels prescribed in the standards of Subpart B of this part. These 
criteria are specified in order to further clarify and define such 
standards. Equivalent measurement procedures may be used for 
establishing compliance with these regulations. Any equivalent 
measurement procedure, under any circumstance, shall not result in a 
more stringent noise control requirement than those specified in this 
regulation using the measurement procedures in Subpart C.
