This standard specifies the test methods for milking equipment and components that meet the requirements of GB/T 8186, 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. Other test methods may be used if similar results can be obtained. The test procedures described in Appendix A are intended primarily for laboratory determination. Appendix C gives a procedure for on-site testing, which can reduce testing work and time, and Appendix D is the corresponding test report format.
