【正文】 azard is addressed in this document by the inclusion of a security test. However, as the fixing of such products to the container is userdependent, the risk of an accident cannot be pletely eliminated. This document sets out labelling requirements stating that parents or carers should not leave children unattended whilst being fed with a product containing a feeding teat or drinking accessory and that children should not be allowed to use feeding teats as a soother. 假如飲水設備的零部件在使用時脫落就很容易造成窒息危險 ,該類危險包含在本標準的安全測試內(nèi)容內(nèi) .但是當這些產(chǎn)品是由用戶組裝使用時造成類似的危險不能完全消除 . 因此本文件建立了一些貼標要求說明應在父母或監(jiān)護人看護下讓兒童使用奶瓶或其它飲水設備及不能將進食用奶頭用作安慰奶頭 . The Technical Committee considered the possibility of standardizing both the sizes of feeding teats and ranges of flow rates. However, it was decided that the many binations of container systems in use precluded the standardization of sizes. It is remended that all container and feeding teat binations used are matched ponents. 本技術委員會考慮了將進食奶頭的尺寸及食物的流動速度標準化的可能性 .但 是實際所使用的與其相匹配的容器差別很大致使將奶頭尺寸標準化的可能不可能實現(xiàn) . 建議組合使用的奶頭與容器應是相互匹配的部件 . The provision of meaningful flow rate information is difficult because of several factors including hole diameter, teat thickness, hole shape /type of feed, and also how individual infants suck the teat. Accordingly, it was decided not to include a test for flow rate but to remend that manufacturers provide information on flow rate and hole size that is appropriate to their particular product. 將食物的流動速率進行規(guī)定也是很困難的 ,因為流動速率與孔徑的大小 ,奶頭的厚度 ,孔的形狀及食物類型及 嬰兒吸吮方式有關 . 因此本標準沒有制定流動速率的相關測試但是建議制造商提供流動速率及特定產(chǎn)品的孔徑的信息 . It is remended that manufacturers and suppliers operate to EN ISO 9001 [1] standard for quality management systems. 建議制造商及供應商按 EN ISO 9001 [1]標準操作質(zhì)量管理系統(tǒng) . 1 Scope範圍 This part of this document specifies general and mechanical requirements for materials to be used for the manufacture of: 本部份文件指定了如下使用材料生產(chǎn)之通用機械要求 ?????Reusable feeding teats and drinking accessories。C to each of the following three numbered graduations: ??lowest numbered graduation。 0,25) Nm. Alternatively fit all the individual parts of the assembly together. Secure the container at an angle of 45??to the major axis (see Figure 11). Using a suitable clamping device, hold either (10 ??2) mm of the tip of the nipple of the teat or (10 ??2) mm of the sides of the accessory which have been pressed together in line with the major axis. Apply a preload of (5 ??2) N at 45 degrees to the major axis of the feeding teat or drinking accessory to ensure alignment, prior to increasing the force to (60 ??5) N in the same direction, at a crosshead speed of (200 ??5) mm/min. Maintain for (10 ??0,5) s. NOTE Clamps or other devices should hold the ponents securely during the test without causing damage which might affect the test result. Any results where such damage occurs should be disregarded. 產(chǎn)品上有圓環(huán)蓋時將其用 177。C之冷開水 : 最低刻度線 。5% 帶數(shù)值刻度 100ml: 177。 重復 使用的喂養(yǎng)奶嘴及飲水附件 ?????Reusable feeding bottles and drinking cups。 ??highest numbered graduation。 .并將其它 部件裝配到一起 . 在與容器主軸成 45?角 的方向上將其固定 ??見圖 ????用一個合適的夾具 ?夾住 距 奶嘴奶頭 (10 ??2) mm處或已與 主軸壓縮在一起的附件側(cè)邊 (10 ??2) mm處 . 以 與 奶嘴或飲水附件 主軸方向 成 45??角 的方向上 預施加一個 (5 ??2) N的拉力 ,以 (200 ??5) mm/min的速度在 該 方向 上 增加拉力到 (60 ??5) N,並保持 (10 ??) 秒 . 備注 : 測試時應使用合適的夾具或其它裝置將部件固定 ,并且不可產(chǎn)生導致測試失敗的損傷 .任何在上述之損傷所測之結(jié)果均為無效 . Key A Direction of tensile force Figure 11 — Fixture for security/retention test Flexibility test 彈性測試 Principle 測試原理 A force is applied to the end of the protrusion or straw using a steel plate and the point at which the protrusion or straw bends is measured 在突出物或吸管的未端用一塊鋼板施加一個壓力 ,測量突出物或吸管的彎曲點的位置 . Method 測試方法 Assemble the protrusion (or straw) with its matched ponent (s) including the container. Clamp the container in a suitable device. Apply a force of (10 ??1) N at a crosshead speed of (10 ??2) mm/min to a 100 mm x 100 mm polished steel plate positioned at right angles to the major axis of the protrusion (see Figure 12). The end of the protrusion can be moved a maximum of 5??off the major axis at the start of the test. Measure the length from the locking ring to where the protrusion (or straw) bends. If no locking ring exists measure the length from where the protrusion (or straw) emerg。 Check the mass of the water using a balance, with an accuracy of ??0,1 g. Ensure that the base of the meniscus of the water is level with the marked line of the graduation. 按如下三個刻度裝入 (20 ??5) 186。 ??numbered graduations ??100 ml: ??5 ml. 測定容積精度 當按照 有數(shù)值刻度的奶瓶及飲水杯之容積精度測定 (如標記有數(shù)值刻度 )測試 ,其精度要求如下 : 帶數(shù) 值刻度≧ 100ml: 177。 重復 使用的喂養(yǎng)奶瓶及飲水杯 ?????Singleuse feeding bottles, feeding teats, feeding bags and drinking accessories, which do not contain fluid when purchased. 在購買時 沒有 液體的 一次性 使用的喂養(yǎng)奶瓶 ?喂養(yǎng)奶嘴 ?喂養(yǎng)包及飲水附件 ?
