This standard is not ap
9、plicable to thermal packs for the treatment of sports injuries or for use as hot water bottles. This standard does not deal with requirements for materials in contact with food, which are defined by existing regulations. 2 Normative references This European Standard incorporates by dated or undated
10、reference, provisions from other publications. These normative references are cited at the appropriate places in the text and the publications are listed hereafter. For dated references, subsequent amendments to or revisions of any of these publications apply to this European Standard only when inco

EN 71-3 Safety of toys - Part 3: Migration of certain elements. 3 Definitions For the purposes of this standard the following definitions apply: 3.1 cooler pack sealed container filled with a cold-retaining medium intended
13、for use in conjunction with an insulated domestic food container for example one complying with EN 12546-2:2000. NOTE: The pack is pre-cooled before use by, for example, storage in a domestic freezer or refrigerator. 3.2 service temperature limits minimum and maximum temperatures between which a coo
14、ler pack is intended to operate. 3.3 surface coating ink, paint, varnish, lacquer, transfers, etc applied to the surface of the cooler pack. 4 Requirements 4.1 Contents The cold retaining medium shall not be considered as dangerous (see Note 1). If water is used as the cold retaining medium or part
15、of it, it shall be of quality fit for human consumption (see Note 2). It shall be possible to present all data for checking compliance with the requirements of this clause. NOTE 1: Attention is drawn to the Council Directive of 7 June 1988 (88/379/CEE) referring to the classification, packaging and
16、labelling of dangerous preparations and requiring that the cold retaining medium not be dangerous. NOTE 2: Attention is drawn to Council Directive of 15 July 1980 (80/778/CEE) relating to the quality of water intended for human consumption. 4.2 surface coatings 4.2.1 A coating, if any, shall be firm
17、 and not removable when tested in accordance with 5.1. 4.2.2 The coating, if any, shall comply with the requirements of EN 7 1-3 for toxic metals in coatings if more than 10 mg can be obtained from the cooler pack by a physical method of removal. O BSI 07-2000 - Page 4 EN 12546-312000 4.3 leak resis
18、tance The cooler pack shall be leak resistant at any temperature between the service temperature limits and comply with the requirements of 4.4 to 4.7 after being subjected to testing in accordance with 5.2. 4.4 load resistance The cooler pack shall not be damaged so as to cause leakage at ambient t
19、emperature when tested in accordance with 5.3. 4.5 thermal shock A cooler pack shall be able to withstand a thermal shock without damage or leakage when tested according to 5.4. 4.6 impact resistance After testing in accordance with 5.5 there shall be no leakage or breakage of the cooler pack likely
20、 to affect future performance. 4.7 puncture resistance A cooler pack shall not leak after it has been subjected to the puncture test described in 5.6. 5 Test methods 5.1 adhesion of surface coatings Use a self-adhesive tape having a specific adhesion to stainless steel of (400 $r 100) g/cm when remo
21、ved at 180“ at approximately 1 m/s. Apply the tape firmly to the surface coating on the cooler pack at ambient temperature. Remove the tape swiftly at a speed of about 1 m/s and examine for traces of coating adhering to the tape. 5.2 leak resistance For the purpose of this testing, the minimum and m
22、aximum service temperatures shall be those declared by the manufacturer or, where no service temperatures are declared, shall be (-1 8 1i 2) “C and (+60 f 2) OC. Perform the following cycle 20 times: 1. 2. 3. 4. store the cooler pack at the minimum service temperature for 2h; leave the cooler pack a
23、t ambient temperature for 15 min; place the cooler at the maximum service temperature for 30 min; leave the cooler pack at ambient temperature for 15 min. Examine for leakage before carrying out the other tests. 5.3 load resistance For the purpose of this test, the cooler pack shall be placed on an
24、horizontal hardwood board of 3 cm thickness and the load applied through a wooden panel. Apply for 10 min a force equivalent to 1 N for every cm2 of its greatest projected surface area within 30 s of reaching stability at: O BSI 07-2000 STD.BSI BS EN 1254b-3-ENGL 2000 Ib29bbY 0857847 22b E Page 5 EN

Examine for leakage. 5.4 thermal shock With the cooler pack initially at ambient temperature, immerse it for 5 min in water at the maximum service temperature. Remove it fi-om the water and immediately thereafter store it for 2
26、 h in a freezer at the minimum service temperature. Remove it from the freezer, and immerse it for another 5 min in water at the maximum service temperature. Dry it with a cloth and examine for leakage or damage. 5.5 impact resistance Perform 3 drops fi-om a height of (750 f 50) mm onto a hardwood b
27、oard 3 cm thick using a different pack for each of the following conditions: - - at ambient temperature. within 60 s following storage at the minimum service temperature for 2 h; Examine for leakage or breakage. 5.6 puncture resistance At ambient temperature, apply a force of 10 N through a needle o
28、f tip radius 0,4 mm for 10 s once on each side of the pack. Examine for leakage. 6 Marking and labelling A cooler pack shall be legibly and permanently marked with: - - the name or identification mark of the manufacturer, distributor or vendor; the number of this EN standard. The following informati
