据我所了解的是加多一个ABNORMAL HEATING TEST(C22.2 No. 21-M95, Par. 6.16), 因为我也是接触线轴没多久,大家可以探讨一下嘛。。4 m; V9 l# F! N/ r, O# N
一下附上一个测试方法:

One sample of Model _______________ was used for this test.5 Y1 j- s) u* J2 n% _8 i, r9 ]
5 l4 m0 x5 I/ R/ O: T5 K With no portion of the cord withdrawn, the sample was placed on four, single plies of cheesecloth. The cord reel was then wired to draw an overload current of _______ A, at rated voltage, on all conductors which normally carry current. The overload current was equal to 110 percent of the maximum current as limited by the [branch circuit breaker] [overcurrent protection device]. The [branch circuit breaker] [overcurrent protection device] was bypassed for this test.

Four, additional, single plies of cheesecloth were then used to cover the cord reel. The test was then allowed to continue for 7 h, or until the cheesecloth ignited [or the 3 A ground fuse opened].
