This International Standard specifies mechanical tests for milking machine installations in order to verify compliance of an installation or component with the requirements of ISO5707. It also stipulates the accuracy requirements for the measuring instruments.

This International 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 AnnexA 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 AnnexC and a corresponding test report in AnnexD.
