2 z3 M; u, @% y# d在IEC安规条款中是否有明确定义STEADY CONDITION2 R9 v: I- U }+ ?- H
如果没有明确定义,是否可以按个人意识来解释?
* d1 [, O0 K* }: H7 I7 q9 N/ |! mIEC 60335-1 Steady Condition 确实不是定义,但部分特标里会对这个词加以补充。2 J Q/ t8 r! u! i$ H; v
例:60335-2-24 2 r f5 \& I- V% q, I: ^
NOTE 101 Steady conditions are considered to be established when three successive readings of the: q- y! X4 I2 m: v
temperature, taken at approximately 60 min intervals, at the same point of any operating cycle, do not differ by more than 1 K., Z% _" J! `6 M& b$ {+ p- F
例:60335-2-40
3 h2 G' e# {$ A) {3 ]When steady conditions are established, the air flow rate is reduced until it is just sufficient to

特标也没有补充的,按照个人意识来理解吧 |
