GB/T 8187-2011Milking machine installations -- Mechanical tests (English PDF)

Foreword

This standard was drafted in accordance with GB/T 1.1-2009 given rules.

This standard replaces GB/T 8187-2005 "Test Method for milking equipment." this standard compared with GB/T 8187-2005, the main technical content changes as follows.

--- Vacuum measuring repeat measurement accuracy of ± 0.3kPa original increased to ± 0.2kPa;

--- Increasing the sampling rate requires a minimum vacuum recording system and the minimum response rate;

--- Modify the vacuum surge tank effective volume of the gas-liquid separator effective volume, measured milk collection tank effective volume, milk buckets, cans and delivery terms Determination of the effective volume of the contents of the flask, and moved from the standard text in Appendix B, and deleted the GB/T 8187-2005 Appendix B Effective volume measurement;

--- Increasing the vacuum system modulating properties test, measurement pipe slope milking, milk cup depth and the effective length of the inner sleeve.

This standard uses the translation method using equivalent international standards ISO 6690:2007 "Standard Test Method for milking equipment" (in English).

The standard proposed by China Machinery Industry Federation.

This standard by the National Standardization Technical Committee (SAC/TC201) Agricultural machinery centralized.

This standard was drafted. Chinese Academy of Agricultural Mechanization Sciences, Ministry of Agriculture, Agricultural Machinery Testing Station.
