It supersedes BS 5239:1986 and BS 5239:1975 both o

11、f which are withdrawn. This revision includes new requirements for maximum permissible levels of volatile nitrosamines, for ventilation holes in the flange, and new requirements and test methods for the puncture and tear resistance of teats. Minimum flange dimensions are no longer specified. Instead

12、 dummies are required not to pull through an aperture in a template; the template is similar to that used previously in a flexibility test but with the central circular part of the aperture increased in size. Tensile test requirements have also been made more stringent. NOTEBS 5239:1988 did not come

13、 into effect until 28 February 1989, when the Babies Dummies (Safety) Regulations 1978 were revoked. Previously the 1975 edition still applied. NOTEUpon publication of BS 5239:1988, BSI Sales Department will respond to purchase orders for BS 5239 by supplying copies of the 1988 edition. Copies of th

14、e 1975 edition may be obtained by quoting the number “BS 5239:1975”. A reduction in the maximum permissible levels of certain soluble metals or their compounds, in order to align them with those proposed in the European Committee for Standardization (CEN) draft standard for toys, will be considered

15、once that CEN standard is published. The presence of undesirable plasticizers in plastics has also been considered but at present there is insufficient information available on the toxicity of plasticizers or test methods for their determination. When more information is available on this subject it

16、 too will be reconsidered. In 1988 a choking incident involving a “sleep time” dummy, i.e. a dummy without a ring, occurred in New Zealand. Certain dummies appear to be designed with knobs or protrusions that are difficult to grasp in an emergency situation. A method of test to determine the gripabi

17、lity of wet dummies when access is restricted, as in the case of removal from an infants mouth, is therefore required. Until a reliable test method has been developed and appropriate performance criteria established it has been decided that this voluntary standard should specify the incorporation of

18、 a ring behind the flange of dummies. When a satisfactory test method has been developed a further amendment to the standard, regarding the gripability of dummies will be considered. A British Standard does not purport to include all the necessary provisions of a contract. Users of British Standards

19、 are responsible for their correct application. Compliance with a British Standard does not of itself confer immunity from legal obligations. Summary of pages This document comprises a front cover, an inside front cover, pages i and ii, pages 1 to 12, an inside back cover and a back cover. This stan

20、dard has been updated (see copyright date) and may have had amendments incorporated. This will be indicated in the amendment table on the inside front cover.

21、his British Standard specifies requirements for materials, construction, performance, packaging and marking for babies dummies and includes methods of test for performance requirements and recommendations for the use and care of dummies. NOTEThe titles of the publications referred to in this standar

22、d are listed on inside back cover. 2 Definition For the purposes of this British Standard the following definition applies. babys dummy a substitute nipple for a baby to suck or bite on that is not designed to facilitate a baby obtaining fluid 3 Materials 3.1 Dummies shall be made entirely of elasto

23、mers or plastics, or a combination of these, except where the teat is filled with gelatine jelly (see 4.2) and except where the flange contains solid particles to produce a rattle effect in that these particles shall be smooth rounded glass beads and shall be radio opaque to medical X-rays. NOTEDumm

24、ies and their component parts should be manufactured in such a way that the use of the dummy will not be injurious to health or cause mucosal irritation by reason of any leachable constituents, for example, plasticizers (see foreword), of the dummy or of any substance remaining on the surface of the

25、 finished product. 3.2 Dummies or their component parts shall not contain proportions (by mass) of soluble antimony, arsenic, barium, cadmium, chromium, lead or zinc or any of their soluble compounds in excess of the following limits when tested in accordance with Appendix A. 3.3 All elastomer dummi

26、es or elastomeric component parts of dummies, including any filling in the teat (see 4.2), shall not contain in excess of 30 ppb total volatile nitrosamine content, neither shall they contain in excess of 15 ppb of any one volatile nitrosamine, when determined in accordance with BS 7115-11); teat fi

27、lling materials shall be separated from the teats and analysed separately. NOTEThe maximum permissible levels of nitrosamines have been set at somewhat higher levels than was thought to be necessary in order to take into account the variability of test results between laboratories. 4 Requirements fo

28、r individual features NOTEDummies may be made as a one-piece construction or as an assembly of separate component parts. 4.1 Designation of individual features For the purposes of this British Standard, the features of a dummy shall be designated as shown in Figure 1. 4.2 Teat The teat shall: a) be

29、hollow; or b) be solid; or c) contain a solid elastomer filling; or d) be filled with gelatine jelly only. If c) or d) apply, the filling shall not be capable of being removed whilst in use. If the teat is filled with gelatine jelly, this shall incorporate a preservative used for food. NOTEAttention

30、 is drawn to the Preservatives in Food Regulations 1979 (SI 1979 No. 752), concerning preservatives authorized for use in gelatine and gelatine products for human consumption as amended (see SI 1980 No. 931 and SI 1982 No. 15), and to all subsequent amendments. When assembled, or after completion of

31、 moulding of a one-piece article, the effective penetration of the teat shall be checked using the teat penetration gauge shown in Figure 2(a). The teat of the dummy shall be inserted into the centre of the gauge with its major axis vertical and the dummy shall be rotated about its major axis to obt

32、ain the greatest depth of penetration. In this position the teat shall not touch the base of the gauge. NOTEAn example of a design of dummy having an effective length greater than the length of the teat is shown in Figure 2(b). The outside surface of the teat shall be smooth and free from cracks, pi

33、ts and holes. There shall be no hole in the teat in front of the flange such as would permit the ingress or egress of fluids.

34、a, Mon Dec 04 16:39:07 GMT+00:00 2006, Uncontrolled Copy, (c) BSI BS 5239:1988 2 BSI 11-1999 4.3 Flange Flange dimensions shall be such that when tested in accordance with B.7, with the flange oriented in the least favourable position in relation to the aperture in the template, the dummy shall not

35、pull through the template. The surface shall be smooth. Edges shall be radiused and free from any sharpness or projecting points liable to cause injury. The flange shall have two ventilation holes that permit the unhindered passage of a test rod with a diameter of at least 5 mm. These two ventilatio

36、n holes shall be symmetrically located on the flange, their centres shall be at least 15 mm apart and their edges shall be at least 5 mm from the edge of the flange. NOTE 1There may be other holes in the flange but there are no requirements for location or size of any other additional holes in the f

37、lange. NOTE 2The purpose of ventilation holes is to provide an air passage through which a baby could breathe, should the dummy be accidently swallowed, and thereby reduce the risk of the dummy being sucked into the pharynx through the generation of a negative pressure. 4.4 Plug Where the design req

38、uires a plug to be fitted, it shall be of such design and material that it does not cut the teat or crack the flange, either during assembly or afterwards in use. After assembly the plug shall not protrude more than 17 mm beyond the rear of the flange. NOTEA vent hole may be incorporated in the plug

39、. 4.5 Ring 4.5.1 General. A dummy shall incorporate a ring behind the flange to permit ease of extraction from the mouth. 4.5.2 Ring. The surface shall be smooth and free from any sharp edges. The width of the ring (see Figure 3) shall be a minimum of 25 mm and, where flexible materials are used, a

40、maximum of 45 mm. The length of the ring (see Figure 3) shall not be greater than the width. NOTEFor a non-circular ring, the design should ensure that the ring remains in the correct orientation and does not rotate through its point of attachment such that the length can exceed the width (see Figur

41、e 3). The shape of the ring shall permit the unhindered passage of a test rod with a diameter of at least 14 mm (see Figure 3), positioned on and perpendicular to the major axis of the dummy, and with the cross section of the rod in the same plane as the plane of the ring. Where the ring is a separa

42、te component, it shall, after assembly to the dummy, be free to move through an arc of not less than 80 on each side of the major axis of the dummy. Rigid rings shall not lock over the flange. Where moulded as an integral part of the flange, the ring shall be flexible at its juncture with the flange

43、 such that it can be flexed easily through an arc of not less than 80 on each side of the major axis of the dummy. Figure 1 Designation of features Licensed Copy: sheffieldun sheffieldun, na, Mon Dec 04 16:39:07 GMT+00:00 2006, Uncontrolled Copy, (c) BSI BS 5239:1988 BSI 11-19993 The ring shall be a

44、ccessible, even if it is in contact with the flange, so that in the event of an accident it can be readily gripped and used to extract the dummy from a babys throat, and not compound the problem. NOTEThe size, shape and place of attachment of the ring affect its accessibility. 4.5.3 Text deleted 5 P

45、erformance of the complete dummy 5.1 Compression resistance When tested by the method described in B.2, a dummy, in any possible orientation with respect to the direction of the compressive force, shall remain intact throughout the test, with no visible sign of fracture or cracks in the flange, plug

46、, ring or knob or cuts in the teat unless caused solely by the clamping device. 5.2 Bite resistance When tested by the method described in B.3, a dummy shall show no visible sign of fracture or cracks in the flange, or ring and shall exhibit no permanent damage to the teat that would render the dumm

47、y unusable or unsafe. Permanent indentations in the non-flexible parts of the dummy caused by the test jaws shall not constitute failure of the test. 5.3 Tensile strength When tested by the methods described in B.4, whatever position on the circumference of the flange is held in B.4.4 or B.4.5, a du

48、mmy shall remain intact throughout the tests, shall not permanently distort to the extent of rendering the dummy unusable or unsafe and shall show no visible sign of permanent damage to the teat unless caused solely by the clamping device. 5.4 Puncture resistance When tested by the method described

49、in B.5 the teat shall not be cut or punctured. Marking of the surface of the teat shall not constitute a failure. 5.5 Tear resistance When tested by the method described in B.6 the dummy shall remain intact. 5.6 Drop resistance When tested by the method described in B.8 the dummy shall show no visible signs of fracture or any other damage.
