在诸多 IEC/EN 标准提到的 rubbing test, 都规定了使用汽油的规格, 如:
1. IEC60950-1 2nd edition, 第1.7.11章节
2. IEC60065 7th edition, 第5章节
3. IEC61558-1 2nd edition, 第8.15章节
4. IEC60335-1 4th edition, 第7.14章节, 规定的汽油规格大致相同, 描述如下:
The petroleum spirit to be used for the test is aliphatic solvent hexane having a maximum
aromatics content of 0,1 % by volume, a kauributenol value of 29, an initial boiling point of
approximately 65 °C, a dry point of approximately 69 °C and a mass per unit volume
of approximately 0,7 kg/l.
请教: 此规格相当于哪一种汽油? 这里化学名称不明白什么意思, 请帮忙转换成中文的描述.
谈谈大家在进行 rubbing test 的体会. |
