Where appropriate, relevant sections of BS5239 have been ad

    8、opted, viz. requirements for resistance to bite and for the limitation of the presence of nitrosamines. Requirements for puncture and tear resistance were considered inappropriate for feeding teats which are for use with adult supervision and not designed to take the place of a dummy. Requirements f

    9、or maximum permissible levels of certain soluble metals or their compounds have been aligned with those in BS5665-3 which is identical to Part3 of the European Standard EN71. The presence of undesirable plasticizers in plastics has been considered but at present there is insufficient information ava

    10、ilable on the toxicity of many plasticizers or test methods for their determination. When more information is available on this subject it will be reconsidered. Manufacturers should refer to the Materials and Articles in Contact with Food Regulations, Statutory Instrument1987 No.1523 and all subsequ

    11、ent amendments and to the European Commission Directive “Plastics materials b) the name, trademark or other means of identification and the address in the UK of the manufacturer, distributor or retailer; c) the following instructions in English: “WARNING Inspect immediately before and after each use

    12、 and throw away when worn, damaged or punctured, for example by biting. Before use, wash thoroughly and sterilize. Always wash immediately after use. Keep in a dry, covered container. Do not leave in sunlight when not in use. INFANTS MUST NOT BE BOTTLE FED WITHOUT ADULT SUPERVISION. Feeding teats sh

    13、ould not be used as dummies/pacifiers/soothers.”; d) instructions on sterilization; e) if it is inappropriate to turn the teat inside out for inspection and cleaning a statement to this effect. If any substance in common household use, likely to come into contact with the teat, is known to have an a

    14、dverse effect on the materials of the teat, then each pack shall carry a warning that contact with that substance should be avoided. 7.2 Single use, disposable teats, supplied sterilized ready for use Each pack (see6.2) shall carry the following information in a legible form: a) the information in i

    15、tems a) and b) of7.1; b) the following instructions in English; “WARNING Inspect immediately before use and throw away if the pack or its contents are damaged. Do not leave in sunlight prior to use. INFANTS MUST NOT BE BOTTLE FED WITHOUT ADULT SUPERVISION. Feeding teats should not be used as dummies

    16、/pacifiers/soothers. Use once only. Do not re-use.”; c) the word “sterilized”. 1) Marking BS7368:1990 on or in relation to a product represents a manufacturers declaration of conformity, i.e. a claim by or on behalf of the manufacturer that the product meets the requirements of the standard. The acc

    17、uracy of the claim is therefore solely the responsibility of the person making the claim. Such a declaration is not to be confused with third party certification of conformity, which may also be desirable.BS 7368:1990 BSI 09-1999 3 Appendix A Methods of test for performance of the teat A.1 General A

    18、.1.1 Tests shall be conducted at room temperature. A.1.2 For third party certification purposes and for verification of a manufacturers claim that his product conforms to BS7368:1990, the cross-head speed given inA.2 andA.3 shall be used. Alternative manual or mechanical procedures could be used in

    19、other situations applying the load gradually over a period of5s. A.2 Tensile strength test Compress opposite sides of the flange together and clamp, perpendicular to the major axis,102mm of the compressed edges of the flange together using a suitable fixture. Hold, perpendicular to the major axis,10

    20、2mm of the tip of the nipple in a suitable fixture and apply a tensile force of90 3N to the nipple along the major axis of the teat at a cross-head speed of195mm/min to255mm/min. Apply the full load for10 0.5s. A.3 Bite test Using the test jaws shown inFigure 2, with the nipple section of the teat b

    21、etween the jaws apply a force of220 5N to the jaws at a cross-head speed of195mm/min to255mm/min. Apply full load for10 0.5s. NOTEMake sure the machine is capable of stopping at220 5N when using a cross-head speed of 195mm/min to255mm/min or damage to the load cell will result. It is possible to use

    22、 a machine to lower a mass equivalent to220N onto the jaw to prevent the load cell from being subjected to a force greater than220N.BS 7368:1990 4 BSI 09-1999 Figure 2 Jaws for bite testBS7368:1990 BSI 09-1999 Publication(s) referred to BS 5239, Specification for babies dummies.
