DIN EN 60332-1-2:2004 vertical flame propagation for a single insulated wire or cable

DIN EN 60332-1-2:2004 Tests on electric and optical fibre cables under fire conditions—Part 1-2: Test for vertical flame propagation for a single insulated wire or cable—Procedure for 1 KW pre-mixed flame and is for general use, except that the procedure specified of less than 0.5mm2 total cross-section because the conductor melts before the test is completed, or for the testing of small optical fibre cables because the cable is broken before the test is completes. In these cases, the procedure giver in DIN EN IEC 60332-2-2 is recommended.

BS 6853 Annex D: smoke density

 

BS 6853 Annex D/smoke density/BS 6853
 
BS 6853 Annex D: Methods for measuring smoke density
 
The smoke density measurement taken from a material under fire conditions gives an indication of the visibility through the smoke, this is important as reduced visibility in a real fire situation makes it more difficult to escape from a fire hence increasing the threat to human life from the toxic gases, flames and heat.

京沪高铁本月20日(2011年6月)或载客试运行

京沪高铁20日或载客试运行

运营初期将开行两种速度等级列车,实行两种票价

昨天记者了解到,京沪高铁运行试验进入最后阶段,有望本月20日开始载客试运行。

目前,京沪高铁已开始进行最后一阶段的运行试验。这阶段所有京沪高铁动车组全部上线,按照正式运行时刻表来模拟运行停站。相关人士透露,这个阶段的试验运行无限接近京沪高铁正式通车后的运行状况。

记者获悉,运行试验最后阶段,各趟列车各车站的工作人员将基本到位,随时做好向社会开放的准备。根据初步计划,试运行阶段6月11日到19日为不载人阶段,6月20日以后择日开始载人试运行。预计6月底正式运营。
