ANSI/ASABE AD6690:2007, Milking machine installations - Mechanical tests, is an adoption with deviations of the identically titled ISO standard ISO 6690:2007, Milking machine installations - Mechanical tests. Deviations noted in the following Forward sections pertain to those provisions where harmonization could not be achieved between ASABE and the International Standard.

0.2 ANSI/ASABE AD6690:2007 specifies mechanical tests for milking machine installations in order to verify compliance of an installation or component with the requirements of ISO 5707, which has been adopted with deviations by ASABE as ANSI/ASABE AD5707:2007. It also stipulates the accuracy requirements for the measuring instruments.

This Standard is applicable for testing new installations and for periodic checking of installations for efficiency of operation. Alternative test methods may be applicable if they can be shown to achieve comparable results.

Test procedures described in Annex A are primarily for testing in the laboratory. An example of a field test procedure which can reduce the time and effort involved in testing is given in Annex C and a corresponding test report in Annex D.
