stopw-h&timing mechanism (n,， fig. 2). this w-h,，可燃性， 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,，供應(yīng)紡織品阻燃可燃性測(cè)試儀,， fig. 2)， when caused to move by

severance of cord (f,， fig. 2),， s the w-h. timing is read directly.

15 秒表和計(jì)-構(gòu)n，圖2,。該表通過(guò)特殊附件,，通過(guò)與氣體噴射器e，圖2的連接啟動(dòng),。機(jī)柜后部的驅(qū)動(dòng)機(jī)構(gòu)s,，圖2將氣體射流移動(dòng)到其前面的位置，紡織品可燃性測(cè)試儀,，并在火焰沖擊時(shí)自動(dòng)開(kāi)始計(jì)時(shí),。落錘,，圖2因繩索f，圖2的分離而移動(dòng)時(shí),，使手表停止轉(zhuǎn)動(dòng),。計(jì)時(shí)是直接讀取的。
