Abstract: Glass components are widely used in large commercial complexes as fire partitions. After the fire broke out, the water strike behavior during the fire fighting and rescue may cause damage to the glass components, resulting in the spread of the fire. According to the standard hose stream method of building components, hose stream test after fire resistance test of glass components is carried out in this paper. The results show that when the glass insulation performance of the glass component is lost, the glass will open and collapse when the over temperature area touches the water, resulting in the loss of the fire separation function. The fire resistance of the glass component does not reach the fire resistance limit, and the glass component may collapse. Water impact test is necessary after fire resistance test of glass components.

Key words: glass components, fire separation, fire resistance, hose stream
