灯具温度测试

请问：各位
      在灯具温度测试中，采用电阻法测线圈的温度时，当灯具TC=50度时，在50度环境中测温度时，请问测电感镇流器线圈冷态电阻是在25度环境温度中测，还是在50度环境中测量。

不是很懂楼主的意思，但是一般温度测试都会在正负25度的环境下测试。

那是没有标TC，现在是标了TC

ta是ta ,tc 是tc ,

当然是在50度下测试冷态电阻啊

c)The ambient temperature within the draught-proof enclosure shall be within the range of
10 °C to 30 °C and should preferably be 25 °C. It shall not vary by more than ±1 °C during
measurements and during a preceding period long enough to affect the results.
If, however, a lamp has temperature-sensitive electrical characteristics (e.g. a fluorescent
lamp), or if the ta rating of the luminaire exceeds 30 °C, the ambient temperature within the
draught-proof enclosure shall be within 5 °C of the ta rating and should preferably be the
same as the ta rating.
