各位同行，激光类标准IEC/EN60825中判定等级  根据波长和功率就可以确定他的等级吗？有没有知道的朋友可以帮忙发个资料看一下吗？我刚接触这类。。。

LED灯现在用的是IEC/EN 62471 判定，不再用60825了

The latest version of EN60825-1:2007 replaced the old version since 1 Sept, 2010. This new standard has removed the LED from its scope. That means your LED product cannot use this latest standard (EN60825-1:2007) for classification.

In fact, EN62471:2008 will totally replace EN60825-1:1994 after 1 Sept, 2011.  That means you may still use EN60825-1:1994+its amendments for LED classification at this moment. Furthermore, if the luminance of your LED lamp is less than 10000 cd/m2, then your product can skip the test of EN62471.

是手机上的闪光灯，用LED作闪光灯。做的是EN60950-1的标准，标准中要求引用 IEC60825的标准，我不知道怎么判定，要测试哪些数据，所以来问各位同行，不知道是否可以告诉一下？

In fact, there is a loophole in EN60950-1 because it calls up a classification standard which is not applicable to the LED. Perhaps, your lab  also does not know that the latest version of IEC60825-1 has not covered the LED.

# u$ u+ ^: i* }2 x7 ^8 ~( z" oFor the old version IEC60825-1, the LED optical radiation will be measured over the wide range of wavelengths. Then, the result of its optical radiation is compared with Table 1 of IEC60825-1 to determine the CLASS of a LED.

Any way, the component specification will have the CLASS information of LED according to IEC60825-1. Instead of getting the tests by yourself, you have better asking your LED supplier to provide you such the above specification.
