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.
