同意。一般是25度以上 by 客户需求。我们做的最多的950的都是25-40度间。 关于楼主所提的问题的回答,上述好像有两种情况。一种是关于标准中是否有对在实验室测试时,产品所置于的环境温度的提及--即测试条件,还有一种是被测试产品的制造商宣称的该产品所能使用的最大环境温度限制。两个问题应分开讨论!:)
这个950是提到了,但是讲的不是很清楚。见clause1.4.12.3
During the test, Tamb should not exceed Tma unless agreed by all parties involved.
对于tma看clause1.4.12.1 950的温湿度都是厂家自己规定的,承诺自己的产品工作于什么环境就按什么环境测试! 一般35度吧 1.4.12.1 General
