This standard specifies the test methods for milking equipment and components that meet the requirements of GB/T 8186-2005, as well as the accuracy requirements for test instruments. This standard applies to the testing of new equipment and the periodic inspection of equipment operating performance. The test procedures described in Appendices A, B, and C are mainly for laboratory determination. Appendix D gives an on-site test procedure, which can reduce test work and time, and Appendix E is the relative test report format.
