欧洲玩具标准EN71-1之玩具袋
对于玩具袋的要求跟之前的柔软塑料薄膜的要求会有一些不同,但是目的都是一样的,都是为了防止窒息。柔软塑料薄膜是指玩具本身上面的膜装结构,检测是为了防止吸入窒息。玩具袋是特指抽拉线(绳)封口的玩具塑料袋,检测是为了防止儿童将袋子套在头部导致缺氧窒息。至于其他形式的塑料袋,我们将会在玩具包装材料中介绍。1. 标准要求开口周长大于380mm并用抽拉线作封口的玩具袋应符合以下要求:a.

对于玩具袋的要求跟之前的柔软塑料薄膜的要求会有一些不同,但是目的都是一样的,都是为了防止窒息


柔软塑料薄膜是指玩具本身上面的膜装结构,检测是为了防止吸入窒息。


玩具袋是特指抽拉线(绳)封口的玩具塑料袋,检测是为了防止儿童将袋子套在头部导致缺氧窒息。


至于其他形式的塑料袋,我们将会在玩具包装材料中介绍。

1. 标准要求


开口周长大于380mm并用抽拉线作封口的玩具袋应符合以下要求:


a. 用透气材料制作;


b. 至少有1300mm2的通风面积,可以通过最少间隔为150mm的两个通气孔或任何一个等效的通风面积来达到此要求。

2. 安全分析


该要求用于防范不透气而且通风面积不足的玩具袋套在儿童头部引起的窒息危害。


3. 测试方法与安全评价


检查玩具袋的开口是否采用抽拉绳作为封闭手段,如果是,则用钢尺测量玩具袋的开口周长,如果开口周长大于380mm,则适用于该要求。


检查玩具袋所用的材料是否由透气材料制成。可以先从材料的外观判断,一般地,没有打孔的塑料薄膜是不透气的,而布料是透气的。如果玩具袋所用的材料是不透气的,则测量玩具袋上的总通风面积,如果玩具袋上只有一个孔洞,则用适当的方法进行测量和计算。比如,对于最常见的圆形孔洞,可以用游标卡尺测量其直径,计算其面积。如果玩具袋上的孔洞不止一个,则用游标卡尺或者钢直尺测量这些孔洞之间的距离。并用游标卡尺测量这些孔洞的直径,计算出总面积。


如果玩具袋没有采用抽拉绳作为封闭手段或者开口周长不大于380mm,则评定为合格。


对于开口周长大于380mm并使用抽拉绳作为封闭手段的玩具袋,如果由透气材料制成,则评定为合格;或者其通风总面积大于或等于1300mm2,则也为合格。


总之,要么材料透气,要么开孔透气,一切都是为了防止儿童窒息。
