The work of preparing International Standards is normally carried out through ISO technical committees.
9、Each member body interested in a subject for which a technical committee has been established has the right to be represented on that committee. International organizations, governmental and non-governmental, in liaison with ISO, also take part in the work. ISO collaborates closely with the Internat
10、ional Electrotechnical Commission (IEC) on all matters of electrotechnical standardization. International Standards are drafted in accordance with the rules given in the ISO/IEC Directives, Part 2. The main task of technical committees is to prepare International Standards. Draft International Stand
11、ards adopted by the technical committees are circulated to the member bodies for voting. Publication as an International Standard requires approval by at least 75 % of the member bodies casting a vote. Attention is drawn to the possibility that some of the elements of this document may be the subjec
12、t of patent rights. ISO shall not be held responsible for identifying any or all such patent rights. ISO 20966 was prepared by Technical Committee ISO/TC 23, Tractors and machinery for agriculture and forestry. BS ISO 20966:20071Automatic milking installations Requirements and testing WARNING Some o
13、f the tests specified in this International Standard involve procedures which could lead to a hazardous situation. The attention of any person performing tests in accordance with this International Standard is drawn to the need to be appropriately trained in the type of work to be carried out. It is
14、 left to the responsibility of the user to check all national regulatory conditions and health and safety requirements applicable for the relevant country. 1 Scope This International Standard specifies requirements for the construction of automatic milking installations (AMI), including specific saf
15、ety and hygiene aspects and minimum performance requirements and testing, in addition to those described in ISO 5707 and ISO 6690. It does not contain requirements for the design of the building in which the milking installation is installed. 2 Normative references The following referenced documents

The hygiene requirements given in ISO 14159 apply. 5 Functional requirements 5.1 General The milking machine shall fulfil the requi
26、rements specified in ISO 5707. It shall be possible to operate the AMI both for milking and testing purposes. BS ISO 20966:200735.2 Preparation before milking 5.2.1 Cleaning of teats There shall be provision to clean the teats and the parts of the udder in contact with the liners without injuring th
27、e animal. The result of the cleaning operation is checked by inspection of the teat and udder areas after operation. NOTE Annex B presents an example of a method of evaluating the inspection of cleaning of teats and udders, although the ultimate result of cleaning is the milk quality in the bulk mil
28、k tank. 5.2.2 Foremilking There shall be provisions for separation of the foremilk from the milk intended for human consumption. Information shall be provided about the procedures regarding separation of foremilk, and how to inspect the performance. The performance of the foremilk separation shall b
29、e verified during operation. 5.3 Milking 5.3.1 Accidental teatcup detachment The system shall have provisions to detect accidental teatcup detachment so that the AMI can initiate corrective action to attempt to achieve a successful milking. 5.3.2 Milk yield measurement The milk yield for each milkin
30、g shall be measured. The accuracy of milk yield measuring systems shall be stated in the users manual. 5.3.3 Detection of abnormal milk Where an automatic milking unit has provisions to detect abnormal milk from an individual animal and prevent its milk from being mixed with milk intended for human
31、consumption, the abnormal milk detection method together with recommended limit values shall be described in the users manual. NOTE Annex C presents an example of a method of evaluating detection systems for milk deemed as abnormal due to blood or changes in homogeneity with possible limits of blood
32、 levels. 5.3.4 Teatcup removal There shall be provisions to limit the total machine-on time. Methods, procedures and limits shall be stated in the users manual. 5.4 Post-milking teat applications It is recommended that there be means to apply disinfectant and/or skin conditioner to the teats after m
33、ilking. BS ISO 20966:20074 5.5 Milk transport 5.5.1 Diversion of milk The AMI shall have provisions to divert milk identified as abnormal, undesirable or withheld milk before it reaches the storage tank. NOTE The decision to divert undesirable and withheld milk is always taken before milking. The de
34、cision to divert abnormal milk can be taken at any time during foremilking, milking or after milking of the animal. Diverted milk can be transported to a holding tank or a safe means of disposal. 5.5.2 Delivery lines Milk shall be prevented from entering the bulk milk tank during cleaning of the bul
35、k milk tank. Milk shall be prevented from entering the bulk milk tank during milk collection if required by local, regional or national regulations. 5.6 Milk cooling and storage 5.6.1 General A bulk milk tank shall have provision to inform the automatic milking machine (AMM) if milk can be received
36、or not. Cleaning solution shall be prevented from entering the bulk milk tank whilst milk is present in the tank. 5.6.2 Refrigerated bulk milk tank A refrigerated bulk milk tank shall comply, where appropriate, with EN 13732. NOTE 1 EN 13732 was developed for batch milking excluding continuous milki
37、ng such as with an AMM. The cooling system shall have sufficient capacity to cool milk received in an empty bulk milk tank from high-producing animals milked simultaneously in the available milking units. The cooling system shall be designed so that the milk does not freeze, even at low milk flow fr
38、om a single animal into an empty tank. NOTE 2 Milk temperatures and cooling times are usually stated by local, regional or national requirements. 5.6.3 Tank for temporary storage If milk is intended to be stored in a temporary tank (buffer tank) longer than 1 h, such as during milk collection and cl
39、eaning of the bulk milk tank, the cooling time specified by local, regional or national requirements applies (see 5.6.2, Note 2). 6 Cleaning There shall be provisions to initiate automatic cleaning, rinsing or sanitizing of milk contact surfaces for: a) teatcups, between milking of each animal, incl
40、uding surfaces that can come in contact with the animal teat; b) all surfaces that have come into contact with milk detected as abnormal, undesirable or withheld milk, before milking an animal for milk intended for human consumption; BS ISO 20966:20075c) surfaces that have been in contact with unref
41、rigerated milk after a specified time without milking; d) system cleaning after a specified interval. NOTE Cleaning intervals are specified by international, national or local regulations. 7 Instructions for use In addition to the instructions for milking machines, at least the following shall be em
42、phasized in the users manual: a) procedures to be followed in the event of alarms raised; b) use of system check functions; c) entering animal details, events and action points into the AMI management and monitoring system; d) use of the AMI management system, and any sensors, to produce alarms and
43、action lists required by the user as a basis for management of the animals. 8 Management 8.1 Alarms and notifications When the safety of a human or animal is at risk, an alarm shall be transmitted immediately to the human supervisor. When the system detects an error but the safety of humans and anim
44、als is not at risk, a notification shall be directed to the human supervisor at an appropriate time. 8.2 Retrieval of information The user shall have provision to access at least the following time-stamped information for a specified number of days: a) data for each milking, including animal identit
45、y, duration, yield, whether milking was successful or not on all teats, unintended detachment, re-attachment of teatcups during milking, reason for diversion of milk; b) data for each non-milking visit to the milking machine, including animal identity; c) data for each system cleaning, including dur
46、ation and action done, such as rinsing or sanitation; d) data and reason for each alarm; e) identification of each bottle or vial used during automatic milk sampling. NOTE 1 If any of the above information is intended for export to other parties, a suitable format for data transfer can be that speci
47、fied in ISO 117872, ISO 11788-13and ISO 11788-24. NOTE 2 Other information of interest can be: milk quality parameters such as conductivity, somatic cell count, fat content, protein content, urea content; system cleaning parameters such as detergent type and dosage, temperature of the cleaning fluid
48、; milk cooling parameters such as a log of milk tank temperatures.
