救生圈 我有新说法
152 0

救生圈是指水上救生设备的一种，通常由软木、泡沫塑料或其他比重较小的轻型材料制成，外面包上帆布、塑料等。供游泳练习使用的救生圈也可以用橡胶制成，内充空气，也叫作橡皮圈。

目录

分类

船用救生圈整体式救生圈 [1]  integral life buoy（采用圈体一次整体成型工艺制造的救生圈）

外壳内充式救生圈 stuffing life buoy（采用圈体外壳整体成型、内部填充材料的工艺制造的救生圈）

救生圈按制造工艺分为：A型——整体式救生圈 ，B型——外壳内充式救生圈

标记示例

整体式救生圈标记为：救生圈 GB4302—2007A

外壳内充式救生圈标记为：救生圈 GB4302—2007B

生产要求

外观

救生圈外表颜色应为橙红色，且无色差。

救生圈表面应无凹凸、无开裂。

沿救生圈周长四个相等间距位置，应环绕贴有50㎜宽度的逆向反光带。

每个救生圈上应标明其名称、制造厂名、制造编号、制造日期及批号、检验机构检验标志。

尺寸

救生圈外径应不大于800㎜，内径应不小于400㎜。

救生圈外围应装有直径不小于9.5㎜、长度不小于救生圈外径四倍的可浮把手索。此索应紧固在圈体周边四个等距位置上，并形成四个等长的索环。

重量

救生圈重量应大于2.5 ㎏。配有自发烟雾信号和自亮浮灯所附速抛装置的救生圈，重量应大于4 ㎏。

材料

整体式救生圈的材料和外壳内充式救生圈的内充材料应采用闭孔型发泡材料。

性能

救生圈应耐高低温，无皱缩、破裂、膨胀、分解。

救生圈从规定高度投落后，应无开裂或破碎。

救生圈应耐油，无皱缩、破裂、膨胀、分解。

救生圈应耐火，不应燃烧或过火后继续融化。

救生圈应能支承14.5kg的铁块在淡水中持续漂浮24h。

救生圈在自由悬挂情况下，应能承受90kg重量持续30min而无破裂和变形。

对于配有自发烟雾信号和自亮浮灯所附速抛装置的救生圈，释放时应能触发该装置。

当救生圈被自由的悬挂时的时候，它应该是可以在三十分钟承受九十公斤的重物的，且在这一时间段内，救生圈不会破裂，更不会变形。

属具

救生圈可配有属具，包括可浮救生索、自亮浮灯或自发烟雾信号。

区分

游泳圈不是救生圈 [2]  ，千万不能作为救生用具使用。游泳圈与救生圈执行的国家标准是不一样的，救生圈是起救生作用的，它具有很多附属功能;而游泳圈被定义为水上玩具，执行的只是玩具标准。因此，与真正的救生圈相比，玩具游泳圈容易破损漏气，抗压能力很差，极易爆裂，塑料表面遇水湿滑，较难抓握，只能在水上休闲运动中起到一定的辅助或保护作用，如果带到深水区则具有危险性。

选购

救生圈是救生设备中的一个主要种类，通常是作为水上救灾及相关生产经营过程中的安全防护产品。

我国国内救生圈产品主要形式种类有聚苯乙烯包布救生圈、聚氨酯聚乙烯复合救生圈和结皮型聚乙烯救生圈3种。

由于救生圈产品质量参差不齐，价格不一及应用范围不同，所以采购时应认真选择符合配置要求的救生圈 [2]  。

1、合格的救生圈产品，应当具有相关的材料检验报告、型式试验报告及船栓检验证书。

2、国内合格救生圈产品的参考成本价是：聚苯乙烯包布救生圈约55元/只，结皮型聚乙烯救生圈约100元/只左右。因此，价格过分便宜的救生圈很可能是偷工减料的产品，应当谨慎选购。

3、有条件的情况下，要求商家依据标准规范要求，对救生圈的重量、缝线质量、强度、飘浮性、耐高温性及抗损坏能力等项目指标进行必要的核查。

注意事项

救生圈装箱时应注意不使圈体发生变形，运输中应不受损坏。救生圈应存放在干燥的库房内，且应平放。

虽然因救生圈出现质量问题而引发的投诉极少，但任何正规产品都应具备厂名、厂址、合格证、生产日期等基本要素。同时生产时应按照相关质量标准进行操作，而且应附有中文字样的使用说明。质监部门提醒广大市民，救生圈由于是一种特殊的救生设备，选购时一定要留个心眼，以免游泳时酿下大祸。
