Staircase condition after 11mins of burning

Remained stable and is still safely accessible

Collapsing


Staircase condition after 20mins of burning

Did not catch fire, the flames have died down on their own

Burn off completely


Surrounding air

Non toxic

Saturated with large quantities of toxins from wood varnish


 


--- 实验二 ---


试验项目:防火挡板

日期:2014年5月

测试设置

  • 2 个相同的楼梯(硬胶合板,25 毫米)

  • 每个楼梯有 9 个台阶

  • 每个台阶的高度为 17 厘米,深度为 35 厘米

  • 楼梯宽度为 1.23 米

  • 其中一个楼梯采用 亚库斯达Akusta 蒸汽阻燃树脂保护(仅底部有保护),另一个为普通楼梯,未加任何特别保护层。

  • 台阶顶部的温度计测量点位于第四级台阶的顶部。

Test Project: Fireproof Baffle

Date: May 2014

Test Setup:

-          2 identical staircases (hard plywood board, 25mm/1”)

-          Each staircase has 9 steps

-          Each step is 17cm/6’7” high and 35cm/13’8” deep

-          The staircase is 1.23m/48.4 wide

-          One of the staircase is protected with akuSta-Plast Fire Stop (only bottom is covered), One is unprotected

-          The temperature is measured using a thermometer located on top of the 4th step

 

Description

Staircase Protected with Akusta

Unprotected staircase

Temperature after <1min burning

9 0C

> 100  0C

Temperature after >1min burning

10 0C

> 200  0C

Temperature after >1min 30s burning

11 0C

> 300  0C

After 2 mins of burning

- Staircase remained stable

- Temperature: 12 0C

- Walking on the staircase is still possible without additional risk

Cannot carry its own weight, start collapsing

Temperature: > 300  0C

After 3 mins of burning

- Staircase remained stable

- Temperature: 18 0C

- Walking on the staircase is still possible without additional risk

Collapses completely

Temperature: > 500  0C

测试 #1

  • 结构

    • 顶部:屋顶材料(4 毫米 / 0.15 英寸)

    • 底部:硬胶合板

  • 结果

    • 屋顶材料融化并燃烧。

    • 释放有毒物质。


测试 #2

  • 结构

    • 顶部:屋顶材料(4 毫米 / 0.15 英寸)

    • 中间:亚库斯达Akusta 防火材料(2.5 毫米 / 0.08 英寸)

    • 底部:聚苯乙烯

  • 结果

    • 亚库斯达Akusta 防火材料将温度从 1,200°C 降低至 200°C。

    • 聚苯乙烯的燃点较低,但因 akuSta-Plast Fire Stop 的保护,温度保持在燃点以下。


测试 #3

  • 结构

    • 顶部:硬胶合板(20 毫米 / 0.8 英寸)

    • 中间:由 亚库斯达Akusta 防火板(2.5 毫米 / 0.08 英寸)保护的硬胶合板(20 毫米 / 0.8 英寸)

    • 底部:硬胶合板(20 毫米 / 0.8 英寸)

  • 结果

    • 未保护的硬胶合板在几秒内失去结构完整性,木质楼梯完全不可用。

    • 由 亚库斯达Akusta 保护的楼梯在火灾中仍能维持结构完整性,确保疏散或消防员救援安全。


Test #1

Top: Roofing (4mm/0.15”)

Bottom: Hard plywood board

 

Results:

-          Roofing melts & burns

-          Toxic substances are released

 

 

Test #2

Top: Roofing (4mm/0.15”)

Middle: Akusta (2.5mm/ 0.08”)

Bottom: Polystyrene

 

Results:

-        2.5mm/ 0.08” of akuSta-Plast Fire Stop reduce the temperature from 1,200 0C to 200 0C

-        Polystyrene starts burning at a much lower temperature than roofing. Thanks to akuSta-Plast Fire Stop the temperature remains far below the ignition point.

 

 

Test #3

Top: Hard plywood board )20mm/0.8”)

Middle: Hard plywood board )20mm/0.8”) protected by Akusta (2.5mm/ 0.08”)

Bottom: Hard plywood board )20mm/0.8”)

 

Results:

-       The unprotected hard plywood board loses its structural integrity within seconds. A wooden staircase would be completely unusable.

-       A wooden staircase protected by Akusta could still be used during evacuation or fire fighters entering the building.
