對于D型管(guan)(guan)(guan)穿(chuan)布管(guan)(guan)(guan)而言(yan)，另外(wai)的(de)(de)一(yi)個要(yao)(yao)求就(jiu)(jiu)是(shi)要(yao)(yao)有(you)非常(chang)高的(de)(de)阻(zu)(zu)燃性(xing)能(neng)(neng)。因為穿(chuan)線(xian)(xian)(xian)(xian)管(guan)(guan)(guan)是(shi)用(yong)來穿(chuan)電線(xian)(xian)(xian)(xian)的(de)(de)，如(ru)果不(bu)(bu)阻(zu)(zu)燃，可能(neng)(neng)會(hui)引發(fa)火(huo)(huo)(huo)災的(de)(de)情(qing)況。對于電線(xian)(xian)(xian)(xian)管(guan)(guan)(guan)的(de)(de)阻(zu)(zu)燃，我們(men)可以使用(yong)點火(huo)(huo)(huo)試驗來進行檢查。例如(ru)我們(men)要(yao)(yao)取一(yi)段電線(xian)(xian)(xian)(xian)管(guan)(guan)(guan)，然后(hou)用(yong)打火(huo)(huo)(huo)機點燃，之后(hou)打火(huo)(huo)(huo)機離(li)開(kai)電線(xian)(xian)(xian)(xian)管(guan)(guan)(guan)，這(zhe)時點燃的(de)(de)電線(xian)(xian)(xian)(xian)管(guan)(guan)(guan)會(hui)自動熄滅(mie)，也就(jiu)(jiu)是(shi)體現出電線(xian)(xian)(xian)(xian)管(guan)(guan)(guan)的(de)(de)一(yi)個離(li)火(huo)(huo)(huo)自熄的(de)(de)功能(neng)(neng)，這(zhe)就(jiu)(jiu)是(shi)屬于阻(zu)(zu)燃性(xing)能(neng)(neng)的(de)(de)電線(xian)(xian)(xian)(xian)管(guan)(guan)(guan)。另外(wai)還一(yi)種就(jiu)(jiu)是(shi)根本(ben)就(jiu)(jiu)點不(bu)(bu)著的(de)(de)電線(xian)(xian)(xian)(xian)管(guan)(guan)(guan)，都是(shi)符合要(yao)(yao)求的(de)(de)。
