1 This European Standard applies to clipping machines This European Standard specifies safety and hygiene requirements to minimise the hazards which can arise during the commissioning, the use and the maintenance of clipping machines for portioning and closing of casings filled with foodstuffs, and intended to be used in butcheries, meat processing factories, main kitchens and other food processing factories. This European Standard deals with all significant hazards, hazardous situations and events relevant to clipping machines, when they are used as intended and under the conditions foreseen by the manufacturer (see Clause 4). This European Standard is not applicable to clipping machines which are manufactured before the date of publication of this European Standard by CEN. 2 This European Standard covers the following types of machines: Concerning the sort of actuation: — machine for gathering up by hand, power motioned locking-stroke; — machine for automatic-motioned gathering and automatic-motioned locking-stroke. Concerning the removal-system: — machine with removal by fixed or movable clip-guide (see Figures 1 and 2); — machine with spread-removal (see Figures 3 and 4). 3 Description Clipping machines will be used for closing of tubes with a single-clip (one side) or a double-clip (endlocking and startlocking). The machines are equipped with closing tools (punch/die), which make the locking by deforming the locking-element (clip). A removal/gathering is used to form a free space and to gather the tube in a way that the locking equipment can be put over the pressed tail and this can be locked. By automatic action the clipping machine will be placed at the end of the filling-tube and after each ejecting of the filling-portion there are positioned one or two clips at the casing. From the machine the filled portion will be divided with a knife from the skin which still remains on the filling-tube. If necessary, an additional loop for hanging up the package will be attached. 4 Intended use A clipping machine is designed and constructed in such a way, that in combination with a filling equipment, the food stuff will be transported through a filling-tube in a casing, which is gathered on the filling-tube. Afterwards this casing will be closed with a clip. Furthermore, it is usual to close already filled casings, bags or other packages by hand with a free-standing or hand-operated/hand held clipping machine. Although it should be advised against, the standard, taking into account practice, deals with the hazards due to cleaning with pressurised water. With the aim of clarifying the intentions of the standard and avoiding doubts when reading it, the following assumptions were made when producing it: — only designated and instructed persons operate the machine; — place of use is adequately lit.

The mixing shaft can be equipped with wings, screws, rods, paddles or the like. Mixing machines may be equipped e. g. with — cover over the top of the mixing container, — pipe connections for gases, steam, water or vacuum, — protective hood over the front face discharge opening, — lifting devices for mixing shaft, — loading device, — screw conveyor at the discharge opening. 3 Intended use The fresh or frozen meat, meat product, meat pieces or fish, salt, spices and other additives are loaded into the mixing container by hand or by means of a loading device and mixed by the mixing unit. The discharge outlet may be located at the bottom or the front face and can either be a slide, a flap, a pipe, a pump or a screw. During the production of this standard the following assumptions were made: — Mixing machines are installed at a sufficiently lighted place. — They are used only by designated and skilled operators. Although it should be advised against, the standard, taking into account practice, deals with the hazards due to cleaning with pressurised water.

ISO/ASTM 51431:2005 食品加工用电子束和X射线(韧致辐射)辐照装置中剂量测定的实施规程

1 This practice outlines the installation qualification pro-gram for an irradiator and the dosimetric procedures to be followed during operational qualification, performance quali-fication and routine processing in facilities that process food with high-energy electrons and X-rays (bremsstrahlung) to ensure that product has been treated within a predetermined range of absorbed dose. Other procedures related to operational qualification, performance qualification and routine processing that may influence absorbed dose in the product are also discussed. Information about effective or regulatory dose limits for food products, and appropriate energy limits for electron beams used directly or to generate X-rays is not within the scope of this practice (see ASTM Guides F 1355, F 1356, F 1736, and F 1885). Note 1—Dosimetry is only one component of a total quality assurance program for adherence to good manufacturing practices used in the production of safe and wholesome food. Note 2—ISO/ASTM Practice 51204 describes dosimetric procedures for gamma irradiation facilities for food processing. 2 For guidance in the selection and calibration of dosim-etry systems, and interpretation of measured absorbed dose in the product, see ISO/ASTM Guide 51261 and ASTM Practice E 666. For the use of specific dosimetry systems, see ASTM Practices E 1026 and E 2304, and ISO/ASTM Practices 51205, 51275, 51276, 51310, 51401, 51538, 51540, 51607, 51650 and 51956. For discussion of radiation dosimetry for electrons and X-rays also see ICRU Reports 35 and 14. For discussion of radiation dosimetry for pulsed radiation, see ICRU Report 34. 3 While gamma radiation from radioactive nuclides has discrete energies, X-rays (bremsstrahlung) from machine sources cover a wide range of energies, from low values (about 35 keV) to the energy of the incident electron beam. For information concerning electron beam irradiation technology and dosimetry, see ISO/ASTM Practice 51649. For information concerning X-ray irradiation technology and dosimetry, see ISO/ASTM Practice 51608. 4 This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appro-priate safety and health practices and determine the applica-bility of regulatory limitations prior to use.
