IEC 61300-2-19:2012详细说明了确定光纤设备是否适合承受实际使用、储存和/或运输过程中可能出现的高湿度和高温环境条件的程序。该试验的主要目的是允许在给定时间段内，在恒定温度下观察高湿度的影响。第三版取消并取代了2005年出版的第二版。这是一项技术性修订。与前一版相比的变化是重新考虑要规定的严重性和细节。 关键词:高温高湿环境条件

IEC 61300-2-19:2012 details a procedure for determining the suitability of a fibre optic device to withstand the environmental condition of high humidity and high temperature which may occur in actual use, storage and/or transport. The test is primarily intended to permit the observation of effects of high humidity at constant temperature over a given period. This third edition cancels and replaces the second edition published in 2005. It constitutes a technical revision. The changes with respect to the previous edition are to reconsider the severities and details to be specified. Keywords: high humidity and temperature, environmental condition
