EN 71磁铁测试的要求是不是磁通量不能超过50平方千高斯平方毫米,或者不能是小部件,两个条件必须同时不满足还是只要有一个条件不满足就可以FAIL了呢 ?谢谢
4.23 Magnets (see A.51)
4.23.1 General
The requirements in 4.23.2 do not apply to functional magnets in electrical or electronic components of toys.
The requirement in 4.23.3 does not apply to magnetic/electrical experimental sets in which all magnets have a
magnetic flux index less than 50 kG2mm2 (0,5 T2mm2) when tested according to 8.35 (magnetic flux index), or
do not fit entirely in the cylinder when tested according to 8.2 (small parts cylinder).
4.23.2 Toys other than magnetic/electrical experimental sets
a) Any loose as-received magnet(s) and magnetic component(s) shall either have a magnetic flux index
less than 50 kG2mm2 (0,5 T2mm2) when tested according to 8.35 (magnetic flux index), or shall not fit
entirely in the cylinder when tested according to 8.2 (small parts cylinder).
b) Any magnet(s) and magnetic component(s) that become(s) released from a toy, or from a loose asreceived
magnetic component, when tested according to 8.3 (torque test), 8.4.2.1 (tension test,
general), 8.4.2.2 (tension test, seams and materials), 8.5 (drop test), 8.7 (impact test), 8.8
(compression test), and finally, for magnets that are accessible but not grippable (as specified in
8.4.2.1), 8.34 (tension test for magnets), shall either have a magnetic flux index less than 50 kG2mm2
(0,5 T2mm2) when tested according to 8.35 (magnetic flux index), or shall not fit entirely in the cylinder
when tested according to 8.2 (small parts cylinder).
NOTE An example of a magnet that is accessible but not grippable could be a magnet that is recessed.
c) Wooden toys, toys intended to be used in water, and mouth-actuated toys shall be tested according to
8.9 (soaking test) before being tested according to 4.23.2 b) above.
4.23.3 Magnetic/electrical experimental sets
Magnetic/electrical experimental sets intended for children over 8 years shall carry a warning (see 7.20).

ASTM F963和EN71就是有这些细微的差别....呵呵~~~
