自1980年代問世以來，煙霧試驗室已被證明是用途最廣泛的火災測試工具之一。它是用於測量來自燃燒材料的煙霧的最廣泛接受的設備，並且可以在燃燒和非燃燒條件下測量比光密度。它也用於提取有毒氣體。

傳統上一直採用其垂直測試配置，符合BS6401和ASTM E662，並在本頁圖像中進行了顯示。此方向也用於FAA測試。最新的水平配置如左側的縮略圖之一所示。樣品通過錐形加熱器暴露在水平平面上。此測試方法（ISO 5659第2部分）廣泛用於塑料以及船舶和鐵路應用中使用的產品的評估中。最新的EN 45545-2歐洲機動車輛著火測試標準已採用ISO5659-2作為測試方法組的一部分，該方法將用於鐵路行業以對產品和材料進行認證。此外，使用我們的毒性試驗箱選配部件可將煙霧試驗箱用於毒性測量，該選件符合BSS 7239和AITM 3.0005方法。

本煙霧試驗室以盡可能簡單，符合人體工學和使用者友善的方式，集成了完成測試所需的所有必要功能和軟體。

NBS Smoke Chamber

ISO5659-2, BS6401, ASTM E662, IMO FTPC PART 2, NES711, BSS 7239, AITM 3.0005, AITM3.0005, ABD0031

The Smoke Chamber has proved to be one of the most versatile fire testing instruments since it’s inception in the 1980’s. It is the most widely accepted apparatus for the measurement of smoke from burning materials and measures specific optical density under flaming and non-flaming conditions. It is also used for the extraction of toxic gas.

Its vertical testing configuration, conforming to BS6401 and ASTM E662, has traditionally been the arrangement used and is shown in the images on this page. This orientation is also used for FAA testing. The more recent horizontal configuration is as shown in one of the thumbnails on the left. The sample is exposed in the horizontal plain by a conical heater. This test method, ISO 5659 Part 2, is widely used in the evaluation of plastics and for products used in marine and railway applications. The recent EN 45545-2 European rolling stock fire testing standard has adopted ISO5659-2 as part of the group of test methods to be used in the railway industry for the certification of products and materials. In addition the smoke chamber can be utilised for toxicity measurements using our toxicity chamber option, which is compliant with methods BSS 7239 and AITM 3.0005.

The Concept Smoke Chamber incorporates all the necessary features and software needed to complete tests, in as simple, ergonomic and user friendly way as possible.
