Sec. 204.57-3  Test compressor preparation.

    (a) Prior to the official test, the test compressor selected in 
accordance with Sec. 204.57-2 shall not be prepared, tested, modified, 
adjusted, or maintained in any manner unless such adjustments, 
preparations, modifications and/or tests are part of the manufacturer's 
prescribed manufacturing and inspection procedures and are documented in 
the manufacturer's internal compressor assembly and inspection 
procedures or unless such adjustments and/or tests are required or 
permitted under this subpart or are approved in advance by the 
Administrator. The manufacturer may perform adjustments, preparations, 
modifications and/or tests normally performed by a dealer to prepare the 
compressor for delivery to a customer or the adjustments, preparations, 
modifications and/or tests normally performed at the port-of-entry by 
the manufacturer to prepare the compressor for delivery to a dealer or 
customer.
    (b) Equipment of fixtures necessary to conduct the test may be 
installed on the compressor: Provided, That such equipment of fixtures 
shall have no effect on the noise emissions of the compressor, as 
determined by the appropriate measurement methodology.
    (c) In the event of compressor manfunction (i.e., failure to start, 
misfiring cylinder, etc.), the manufacturer may perform the maintenance 
necessary to enable the compressor to operate in a normal manner.
    (d) No quality control, testing, assembly, or selection procedures 
shall be used on the completed test compressor or any portion thereof, 
including parts and subassemblies, that will not normally be used during 
the production and assembly of all other compressors of that category 
which will be distributed in commerce, unless such procedures are 
required or permitted under this subpart or are approved in advance by 
the Administrator.
