2、05版：直接用带关节的试验指施加20N的力进行试验。作者: ylzyt 时间: 2009-7-7 09:29
没有找到IEC60335-1:1991版，不知道英文是怎么说的，个人觉得98版里面“如果该指进入开口，再用原带关节试验指重复试验”有歧义，因为在前一句话中已经说明“如果试验指进入不了开口，则用直型无关节指加力到20N”带关节试验指是不能进入的，再重复试验也就没有意义了。还有就是标准中用的不明显的力，而不是5N，这个要怎么去理解？作者: milighost 时间: 2009-7-7 18:39
没有找到对应的老IEC版本，但是中文GB4706在翻译的时候是有一些问题的。% R& ^( G1 n) t4 @9 p! S( q
IEC的2001版是这样描述的“Test probe B of IEC 61032 is applied without appreciable force, the appliance being in every possible position except that appliances normally used on the floor and having a mass exceeding 40 kg are not tilted. Through openings, the test probe is applied to any depth that the probe will permit and is rotated or angled before, during and after insertion to any , A! ~7 e) q4 T6 S5 yposition. If the opening does not allow the entry of the probe, the force on the probe in the / F$ j9 R& D' `5 pstraight position is increased to 20 N. If the probe then enters the opening, the test is repeated with the probe in the angled position.“ " e4 T0 W: t h原义实际是“带关节的试指对器具任何一个可能的位置不施加明显的力（不知道老版本是不是制定5N的力）进行检查，并且试指在进入开口前，进入过程中，进入之后都要在最大的进入深度旋转和弯折关节”，“如果试指不能进入，则将试指关节挺直施加20N的力，如果试指进入了，那么在这种情况下所达到的深度，重复进行旋转和弯折关节检查是否触及带电体。”, {" Z+ r6 u; m) }

注意重复的内容是在20N的力下进入的深度进行旋转和弯折关节，不是重新不施加力来检查。 ( r6 m9 J. Z' O7 q 6 J& j/ M$ A% w( u4 I) @3 L0 g+ y8 G另外，在2006版IEC里增加了一个注释明确了不明显的力是指小于1N。 $ j/ M- Q. @0 p" |9 L& O7 mNOTE 2 ”Without appreciable force” is considered to be a force not exceeding 1 N.作者: peter1715 时间: 2009-7-7 20:44
直型无关节指加力到20N不能碰到带电体和运动部件就认为是安全的作者: caballo3157 时间: 2009-7-7 20:55
