    Before the shutter classification introduced the national standard, the high gauge management experts advise:
    将按国家标准《门和卷帘的耐火试验方法》GB7633进行耐火试验,达到包括背火面温升在各项判定条件的要求,耐火极限≥3.0h的,称为特级卷帘,凡是在耐火试验中不以背火面温升作为判定条件的统称普通卷帘门。
    Will be effected according to the national standard fire test method of the doors and rolling GB7633 fire-proof experiment was carried out, including to back fire surface temperature rise in requests for determining conditions of the refractory extreme acuity 3.0 h, called super shutter, where there are not in the fire test to back fire surface temperature rise as a condition of determining generally referred to as the ordinary shutter.
