" g6 P- ^4 u7 t+ g, O5 K& M这不是重点，重点的是这类别产品需要在户外使用，就如我们在高速公路上用来显示“前面有事故，请注意慢行”的显示屏；因为现在客户有要求，需要对户外的标准也一并进行测试，所以想请教如果要去美国市场，如果用灯的标准做，应做什么户外标准测试；若果当IT产品，又应按何户外标准做测试呢？不知道各位有何高见？% {2 Z O0 s' O" o a1 R8 [( Y

顺便也问问，对于UL与ETL两个标志，大家有何意见或建议呢？还有没有其他的选择？作者: micshang 时间: 2011-1-4 10:25
国外情况不太了解，国内类似显示屏是依据SJ/T11141-2003标准的，其中安全是引用的信息技术设备安全标准GB4943。而且，国内室内LED屏作CCC认证时，也是归于与计算机连接的信息技术设备（显示设备）中。作者: samzhu 时间: 2011-1-4 10:41
我司做过LED显示屏的UL认证 标准是UL60950 但是不知楼主的产品跟我做的是否一样.作者: jerrytown 时间: 2011-1-4 23:44
也就是我们平常接触的LED显示屏，应该没有多大区别的。 " `6 X9 L7 T# r7 C8 w0 X# R + b) _3 Q0 L K! B, k8 _( S现在有建议做UL60950-1+UL60950-22的标准，-22是户外测试标准，好像比较苛刻～所以想了解了解看有没有其他简单的标准可供参考～1 S5 l* y6 w f/ s$ c, f( d t! c

2楼的兄弟，按照你们公司做的UL大概多少钱呀？作者: samzhu 时间: 2011-1-6 09:53
我公司是UL的目击实验室..像你这样的产品UL的规费大概去到4.5万左右一个型号.再加一个型号大概要增加8000 具体还要看过产品资料才可以确定. 照楼主你说-22的,那你的产品应该是户外使用了 是吧.标准还有一个是UL60950 以下是一些信息：Safety of Information Technology Equipment' _# D5 r# s1 p
