是模拟荧光灯寿命将尽的状态测试.类似GB里也有这个测试.判断测试是否PASS的条件如下:
a) Any flaming is contained in the enclosure,
b) There are no burn-through openings created in the enclosure,
c) There are no dislodged particles of glass larger than 3 mm (0.1 in),
d) The combined area of any charred black spots does not exceed 75 mm2 (0.12 in2) [not
including the area described in (e)],
e) There is no charred black area around the tube wider than 3 mm (0.1 in) measured
perpendicular to the bulb wall, and
f) No more than a small amount of smoke, similar to that of an overheated 1 W carbon resistor,
is emitted.

可以说说测试的具体情况吗？

emission-mix-free test就是灯丝单端发射测试，测试方法如下：

（１）准备６ＰＣＳ样品，３pcs一端发射，另外３PCS对端发射；

（２）在自由环境下，灯头在上，在输入电压和频率下使光源工作（包装说明灯泡不会出现灯头不会在上运行时除外）；

（３）测试过程中，观察灯泡是否会出现起火，冒烟，或泡壁产生裂纹。灯泡有起火迹象，立即终止测试；
