标准理解--EN60335-2-29
标准EN 60335-2-29中,第十章输入的10.102条款:10.102 The arithmetic mean value of the output current shall not deviate from the rated d.c. output current by more than 10 %.个人觉得,意思是输出电流的算术平方根与额定输出电流的偏差不得超出10%,那么就应该是+/-10%。另一个同事说是+10%,
大家来讨论下。。。
同意楼主的看法 正负10% +10%
具体理解可以看335-1的10.1或10.2中同样的描述
注意, 安规只是讲安全的, 跟产品功能,性能什么的是没什么关系的 kerve 发表于 2012-3-12 15:29 static/image/common/back.gif

支持,只是指+10%。 本帖最后由 小米 于 2012-3-12 16:17 编辑

这是60335-2-29的要求啊,而且10.1和10.2用的也都是"deviate" 而不是"exceed"
"deviate from the rated d.c. output current by more than 10 %”应该重在"deviate",
偏离不就应该是上下偏差吗?
我对产品的性能什么的不关注,我只关注产品符不符合标准要求。。。

正因为10.1和10.2有"deviate", 所以可以更好的去理解"deviate"是什么含义
-1部分是-2的基础
'偏离'跟'上下偏差'不是同一个概念, -1部分中的"deviate"都是有"+" 或"-"。 "10%"肯定不包括"-10%"
changer是哪类电器呢? 从产品来看, 只有'heating appliances and combined appliances' 才有下偏差。 本帖最后由 小米 于 2012-3-12 16:35 编辑
根据-2 Cl.5.101 Battery chargers are tested as motor-operated appliances.
-1部分有"+" 或"-"的是"deviation",而且都有固定的值,既然"deviation"有"+"或"-",那么"deviate"就应该有"+"和"-"

"deviate"是应该有"+"和"-",那10%代表"+10%" 还是"+/-10%"?
charger is treated as motor-operated appliances, so it is only + limits, that means 10% should be "+10%" only NB has different understanding on this point also. eg. in some ITS' reports, it is said "+/-10%" but in some TUV SUD (TUV PS) reports, it is said "+10%" only.
For me, I consider it is "+10%" only 我的观点是+/-10%,且我们的产品已经做过很多款ITS和TUV RH的都有,也都是按+/-10%考虑。
