后松脱出危险磁石和危险磁石部件是不可接受的.

What is a hazardous magnet or magnetic comp 什么是危险磁石和磁石部件

A magnet, or component with an imbedded magnet, that has a flux index greater than 50  And
一个磁石,或含有内嵌磁石的部件,磁通量指数大于50 和

Fits entirely in one of the following shapes:  落入以下形状尺寸中之一的

尺寸 ： D直径（<11mm ) X L 长度( <32mm ) ;
           D直径（<26mm ) X L 长度( <5mm ) ; 或  D 直径 < 22mm .


If as-received, the following warning is required:  如果是接收状态,需要如下警告语:

This product contains (a) small magnet(s).  Swallowed magnets can stick together across intestines causing serious infections and death. Seek immediate medical attention if magnet(s) are swallowed or inhaled.
此产品含有(一个)小磁石,被吞咽的磁石会隔着肠壁吸在一起造成严重的感染甚至死亡.如果磁石被吞咽或吸入应立刻寻求医生的帮助.

8.25 Magnetic Flux Index 磁通量指数

Use specified gauss meter to measure flux-index  用指定的高斯计测量磁通量指数

Measure magnetic components with the magnet still in the component
当磁石仍停留在部件里时，测量磁石部件。

Measure pole area of the magnet  测量磁石的极面积

Remove the magnet from magnetic components to measure the pole area
将磁石从磁石部件中取出，测量极面积

Calculate the flux index  计算磁通量指数

Multiply the area of the pole surface (mm2) of the magnet by the square of the maximum flux density (kg2) 最大流量密度的平方(kg²)乘以极面积(mm²)
