我就问两句
1.Easily touched surfaces of equipment RATED for a maximum ambient temperature above 40 °Care permitted to exceed the values of Table 19 in NORMAL CONDITION, and to exceed 105 °C in
SINGLE FAULT CONDITION, by not more than the amount by which the maximum RATED
temperature exceeds 40 °C.
2.If easily touched heated surfaces are necessary for the processing or heating of materials, or
where otherwise not avoidable, they are permitted to exceed the values of Table 19 in NORMAL
CONDITION and to exceed 105 °C in SINGLE FAULT CONDITION, provided that they are
recognizable as such by appearance or function or are marked with symbol 13 of Table 1.
Equipment heated by its environment to temperature values exceeding the values in Table 19
in NORMAL CONDITION and 105 °C in SINGLE FAULT CONDITION need not to be marked with
symbol 13
我就想问下红色的两句是什么意思，谢谢,理解起来很纠结

1、允许在正常情况下超过表中的温度值，以及在单故障情况中超出105度温度，但超出的温度差值不允许超过最高额定温度值-40度的差值。
举例：exceed 40 by 10 degrees的意思是超出40度10度，那么温度超过表中的温度值和单故障105度值时，超出值不能超过原有限值或105度10度。如单故障情况的105度，可以超出105度，但温度值不能超过105+10=115度。
2. 由于环境温度升高而导致温度升高，并超出...值的装置，不需要标识13#标记。 passagere 发表于 2016-5-3 19:02 static/image/common/back.gif
