ハイライト
DIN CEN/TS 1187 に準拠した、屋根用の火災時挙動試験装置です。規定の試験法 3 に従い着火材、送風装置、輻射熱パネルを用いて試験をおこないます。
DIN CEN/TS 1187 では屋根の外部火災暴露時における挙動を調べる 4 種類の試験法が規定されています。TDP T3 は試験法 3 に準拠した装置です。
試験法 3 の評価項目:
- 屋根表面材への延焼性
- 屋根構造内部材への延焼性
- 火炎の貫通性
- 燃焼物や溶融物の有炎滴下および焼け落ちの発生と影響
試験法 4 に準拠した装置（TDP T4）も提供しています。
Testing of Multi-Layer Roof Structures under Realistic Environmental Conditions
From a fire protection perspective, roofs should be considered to be a system. In certain countries, along with classification of the fire behavior of the individual components used, the fire behavior of the entire roof structure must therefore also be assessed.*
The TDP T3 measures specimens that are representative of the roof assembly in terms of the type and number of roof layers, including existing thermal insulation layers, vapor barriers, etc.
Specimens with a minimum width of 1.2 m and minimum length of 3 m are tested.
In order to carry out a test in accordance with test method 3, the use of a wind device and a radiant heater is required in addition to incendiary devices consisting of a roof construction. The TDP T3 is equipped with a wind device allowing for a defined air flow to be set parallel to the specimen. The heat radiator mounted above ensures symmetrical heat flow distribution on the surface of the specimen. This provides realistic conditions for investigating the fire behavior of a roof structure.
The tiltable sample holder allows for the testing of specific roof pitches. The movable base of the wind device enables positioning at the correct distance from the specimen. The radiant heater of the TDP T3 is attached to the frame of the test rack and can be adjusted in height to set the required distance from the specimen.
