Foreword
This document (EN 13732:2002) has been prepared by Technical Committee CEN/TC 153 "Food processing
machinery - Safety and hygiene specifications", the secretariat of which is held by DIN.
This European Standard shall be given the status of a national standard, either by publication of an identical text or
by endorsement, at the latest by May 2003, and conflicting national standards shall be withdrawn at the latest by
May 2003.
This document has been prepared under a mandate given to CEN by the European Commission and the European
Free Trade Association, and supports essential requirements of EU Directives.
For relationship with the EU Directives, see informative Annex ZA, which is an integral part of this document.
In this European Standard the annexes A, B, C, D and E are normative.
According to the CEN/CENELEC Internal Regulations, the national standards organizations of the following
countries are bound to implement this European Standard: Austria, Belgium, Czech Republic, Denmark, Finland,
France, Germany, Greece, Iceland, Ireland, Italy, Luxembourg, Malta, Netherlands, Norway, Portugal, Spain,
Sweden, Switzerland and the United Kingdom.
Introduction
This document is a type C standard as stated in EN 1070:1998.
The machinery concerned and the extent to which hazards, hazardous situations and events are covered are
indicated in the scope of this document.
When provisions of this type C standard are different from those which are stated in type A or B standards, the
provisions of this type C standard take precedence over the provisions of the other standards, for machines that
have been designed and built according to the provisions of this type C standard.
1 Scope
1.1 This European Standard specifies requirements for design, construction, performance, suitability for use,
safety and hygiene of refrigerated bulk bovine milk coolers and the related methods of test.
It applies to refrigerated bulk milk tanks with air cooled condensing units and automatic control intended for
installation on farms or at milk collecting points. It applies to tanks for two milkings (24 h), four milkings (48 h) and
six milkings (72 h), in which the cooling takes place totally or partially within the tank.
Performance requirements in 5.4.1.2.1 and 5.4.1.2.2 do not apply to tanks where cooling does not take place totally
within the tank nor where the tank is associated with a continuous system of milking (e.g. milking with robot).
1.2 This European Standard does not cover:
 mobile tanks;
 tanks intended to be tilted for drainage;
 equipment for delivering the milk to the tank;
 equipment for pre-cooling or instant cooling of the milk.
1.3 This standard covers significant hazards at machines falling within this scope when used as intended by the
manufacturer and as identified by risk assessment (see EN 1050:1997).
Noise is not considered to be a significant hazard for bulk milk coolers. This standard includes information in 7.1
and in annex A concerning the manufacturer's declaration of the noise emission level of the cooler.
1.4 This standard does not cover the calibration requirements for the tank to be used as a system for payment
purpose.
1.5 This standard applies primarily to the machines which are manufactured after its date of issue.
