1.1 This document specifies requirements for design, performance, safety and hygiene of refrigerated bulk milk coolers and the related methods of test. NOTE The informative Annex J gives some elements regarding the estimation and calculation of energy consumption. This document deals with all significant hazards, hazardous situations and events relevant to bulk milk coolers on farm, when they are used as intended and under the conditions of misuse which are reasonably foreseeable by the manufacturer (see Clause 4). It applies to refrigerated bulk milk tanks with air-cooled condensing units and automatic control intended for installation on farms or at milk collection 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 (non-pre-cooled milk) or partially (in case of pre-cooled milk) within the tank. It also applies to tanks in combination with a continuous system of milking (e.g. milking with robot). 1.2 This document does not cover: - mobile tanks; - tanks intended to be tilted for drainage; - equipment for delivering the milk to the tank; - equipment for pre-cooling of the milk; - the hazards due to the use of other energy than electrical energy; - pressure aspect of vacuum tanks (i.e. tanks where the inner part of the vessel is designed to operate at a pressure below atmospheric pressure). 1.3 Noise is not considered to be a significant hazard, but relevant for bulk milk coolers. This document therefore 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 document does not cover the calibration requirements for the tank to be used as a system for payment purpose. 1.5 This document is not applicable to bulk milk coolers on farm which are manufactured before the date of its publication as EN.

This document specifies a procedure for the determination of the citrinin content in food (cereals, red yeast rice (RYR)), herbs and food supplements by liquid chromatography tandem mass spectrometry (LC-MS/MS). This method has been validated for citrinin in red yeast rice and in the formulated food supplements in the range of 2,5 µg/kg to 3000 µg/kg and in wheat flour in the range of 2,5 µg/kg to 100 µg/kg. Laboratory experiences have shown that this method is also applicable to white rice, herbs such as a powder of ginkgo biloba leaves and the formulated food supplements in the range of 2,5 µg/kg to 50 µg/kg.

This International Standard describes the quantitative liquid chromatographic determination of specific sugars (galactose, glucose, fructose, sucrose, lactose, and maltose) in various milk and milk products, applying arabinose or fucose as internal standards. The method is applicable for the following different dairy matrices: milk, milk powder, chees, whey powder, infant formula, dessert and yogurt. Soy containing dairy products are excluded. The determination of the lactose content in low lactose milk products is excluded. A sophisticated high performance anion exchange chromatographic method in combination with pulsed amperometric detection (HPAEC-AD) is applied. With this method the following 13 different mono- and disaccharides can be separated: fucose, arabinose, galactose, glucose, fructose, sucrose, lactose, lactulose, maltose, melobiose, trehalose, platinose (maltulose) and maltotriose.

This document specifies safety and hygiene requirements of clipping machines (hereafter referred to as machine) for closing of casings filled with foodstuffs (hereafter referred to as product) by using a clip, and which are intended to be used in butcheries, meat processing factories, main kitchens and other food processing factories. Clipping machines are used to close tubes with a single clip (one side) or a double clip (end locking and start locking). The machines are equipped with closing tools (punch/die), which create the closure by deforming the locking element (clip). This document deals with all significant hazards, hazardous situations and hazardous events relevant to machinery when it is used as intended and under conditions of misuse which are reasonably foreseeable by the manufacturer (see Clause 4). This document covers the following types of machines: — semi-automatic machine (see Figure 1 and Figure 2); — automatic machine (see Figure 3). This document does not cover any machines whose closing procedure is only performed manually. This document is not applicable to machinery manufactured before the date of publication of this document by CEN.
