1、
记录燃烧时间,然后按控制面板上的“复位”键,销售纺织品可燃性测试仪,使仪器恢复到初始状态,为下次试验做准备。
2、
剩余试样分别按照步骤1-10进行试验。
所有试验完成后,关闭瓶罐上方连接器气阀。关闭仪器电源,清理接渣盘,使燃烧箱内干净整洁。
3、
本仪器符合《gb/t 14644-2014 纺织品 燃烧性能 45o方向燃烧速率的测定》与《cfr 1610-standard for the flammability of clothing textiles》两标准。如按照cfr 1610进行试验,只需将点火器进行更换即可。

specimen rack (b, fig. 2). the specimen rack provides supports for the
frames in which the specimens are mounted. the angle of inclination is 45°. two
guide pins projecting downward from the cct of the base of the rack travel
in slots provided in the floor of the chamber so that adjustment can be made
for the thickness of the specimen in relation to the flame front. a stop is
provided in the base of the chamber to assist in adjusting the ition of the
rack.
2 样本架b,图2。样品架为安装样品的框架提供支撑。倾角为45°。从机架底座中心向下-的两个导销在燃烧室地板上的槽中移动,可燃性,以便调整试样相对于火焰的厚度。腔室底部设有止动块,以帮助调整齿条的位置。

stopw-h&timing mechanism (n, fig. 2). this w-h, by means of
spe-l attachments, is actuated to a start by connection with the gas jet (e,
fig. 2). a driving mechanism on rear of cabinet ( s, fig. 2) moves the
gas jet to its most forward ition&automatically starts the timing at the
moment of flame impact. the falling weight (h, fig. 2), when caused to move by
severance of cord (f, fig. 2), s the w-h. timing is read directly.
15 秒表和计-构n,供应纺织品阻燃可燃性测试仪,图2。该表通过特殊附件,生产纺织品可燃性测试仪,通过与气体喷射器e,图2的连接启动。机柜后部的驱动机构s,图2将气体射流移动到其前面的位置,并在火焰冲击时自动开始计时。落锤,图2因绳索f,图2的分离而移动时,使手表停止转动。计时是直接读取的。
