1. Select one “fire-rated timber/glazed door” system OR one “fire-rated panel” system in local market and review its fire test reports and assessment reports.
a) Describe the door or panel system, material used and its application in details. The specimen erected onto the test furnace with the brick wall constructed of ordinary bricks of nominal size 240mm x 120mm x 60mm, with 240mm side as the wall thickness, surrounding it.
The specimen is a Fire Resistant Glass System (0.5H) which the thickness of the glass is 16 mm.
b) Describe the fire performance and the fire behavior of the selected system.
The observations foe the specimen behavior during the test is shown below:
Time (min)
Observations
0
The test was started.
1
The exposed glass cracked.
1.5
The exposed glass fell off.
3
The gel layer expanded entirely.
30
No significant change.
36
The gel layer partially cracked.
39
Both integrity and insulation failure did not occur and the test ceased. Fire Resistant Glass System (0.5H) has been subjected to fire resistance test in accordance with BS476: Part 22: 1987, clause 10 for integrity only. The specimen satisfies the performance requirements specified in British Standards foe the periods stated below:
Integrity: No less than 39 minutes
Insulation: No less than 39 minutes
c) Discuss the major factors affecting the fire performance.
In the test BETC-NH-2010-1872, Fire Resistant Glass System (0.5H) passed 39 minutes insulation and integrity test. The size of glass pane for Fire Resistant Glass System can be enlarged no more than 22% both in width and in height. So the maximal overall size of the glass pane can be 1550 mm x 1.22 = 1891 mm (W)
