更确确的说：球压主要针对的测试点：1）起防触电保护的外部的绝缘材料部件；2）固定载流不见得绝缘材料部件。

需要，好像报告上面是有来着~~

刚好有这个疑问呢，也看到很多报告里面球压，灼热丝，甚至针焰都有做，不过标里面是这样描述的，不知道到底是否要做？方法跟其他材料相同吗？
IEC 60598-1：
SECTION 13: RESISTANCE TO HEAT, FIRE AND TRACKING
13.1 General
This section specifies requirements and tests relating to the resistance to heat, fire and
tracking of certain parts of insulating material of luminaires.
For printed wiring boards, reference shall be made to the requirements of IEC 61249.
而IEC 61347-1里面又是这样描述：
18 Resistance to heat, fire and tracking
18.1 Parts of insulating material either retaining live parts in position or providing protection
against electric shock shall be sufficiently resistant to heat.
For materials other than ceramic, compliance is checked by subjecting the parts to the ballpressure
test according to Section 13 of IEC 60598-1:2014.
18.2 External parts of insulating material providing protection against electric shock and
parts of insulating material retaining live parts in position shall be sufficiently resistant to
flame and ignition/fire.
For materials other than ceramic, compliance is checked by the tests of 18.3 or 18.4, as
appropriate.
Printed circuit boards are not tested as above, but in accordance with 8.7 of
IEC 61189-2:2006 and the relevant parts of IEC 61249-2 series. Any self-sustaining flame
shall extinguish within 30 s of removal of the gas flame and any flaming drops shall not ignite
the tissue paper specified.

严格讲是需要做的，实际做球压也没问题
