关于项链
这是因小部件被欧盟召回的项链,既然适用于3-,肯定要满足绳长的要求:环长必须小于380mm,除非25N拉断;
就算拉断后的绳长在25N的拉力下还必须小于220mm;
也就是说市面上的此类项链均不符合标准要求,改进的办法只有一个:每隔小于220mm的长度安装一个有自动断开属性的连接.
对此,有什么看法? 牛X 啊一个项链还有这么多标准 长见识了 其实项链的绳都用橡皮筋的，欧洲标准没有规定橡皮筋的，楼主好好思量啊！ 建议，结合部位的扣用活动式样的，分2个扣，2个链子组成一个长的 不會吧，一個項鏈也有標準依據？ 还有令人头痛的问题：(小球)和小部件
W认为不关小球的问题，如前所述：“小部件所产生的危险是卡在喉咙下部，而球产生的危险是卡在喉咙上部同时也堵塞了气管；喉咙下部叉开与气管相连，喉咙上部比下部大，小圆筒的直径就模拟3-的喉咙下部；因此，容入小圆筒的是小部件问题且与小球无关，不能容入小圆筒但(直径)介于31mm至44.5mm的是小球的问题且与小部件无关。” 测试公司认定为三岁以上，没有必要担心！ 太厉害了，necklace 也有标准啊 far-sight 最新的玩具标准EN71-2011对此有详细的规定
Fixed loops of cords or chains shall either:
have a perimeter not exceeding 380 mm when measured according to 8.36.2.1 (cords and chains
with a single fixing point or with fixing points less than 94 mm apart), or a distance “d” not exceeding
96 mm when measured according to 8.36.2.2 (cords and chains fixed to a toy at points of 94 mm or
more apart), or
separate into parts with a length not exceeding 220 mm (for toys intended for children under
18 months) or with a length not exceeding 300 mm (for other toys) when tested according to 8.38
(breakaway feature separation test). The length of the separated parts shall be measured according
to 8.40 (length of cords, chains and electrical cables).
Toys intended for children of 18 months and over, but under 36 months, having a fixed loop that separates
into one or more parts with a length exceeding 220 mm, shall be accompanied by a warning (see 7.22), visible
in the point of sale, on the toy itself or on its packaging.
Where the distance between fixing points of cords and chains can change during play due to the flexibility of
the toy (e.g. cords on soft filled toys or on textile toys without rigid parts) the perimeter shall be determined
according to 8.36.2.1 regardless of the at-rest distance between the fixing points.
