17 - APPENDIX D2 - MILKING MACHINE TEST SUMMARY

Sets out procedures for carrying out mechanical tests on milking machines to verify that installations comply with the requirements specified in AS 2844.2, Construction and performance. May be used for testing new installations prior to acceptance and for periodic checking of machines for efficiency of operation. Also stipulates the accuracy requirements of measuring instruments and provides examples of the types of report forms which can be used to record tests results.

This standard specifies mechanical tests for milking machine installations in order to verify compliance with the requirements of AS 2844.2. It also stipulates accuracy requirements for measuring instruments.NOTE: Examples of the types of report forms which can be used to record test results are given in Appendices.
