Surface Flame Spread Tester Chamber Flammability Analyzer For Building Materials
Usage:
Protective clothing flame spread tester is according to ISO 15025 standard to design and produce. Surface Flame Spread Tester Chamber Flammability Analyzer For Building Materials can test the flame spread state under a small flame. It is used to simulate the protective clothing is at the risk of ignition to assume the flame spread performance. It is also suitable for fabric material or other similar functional uses of combustible materials.
Introduction:
BS 476 Part 7 specifies a method of test for measuring the lateral spread of flame along the surface of the specimen of a product orientated in the vertical position under opposed flow conditions, and a classification system based on the rate and extent of the spread of flame. Surface Flame Spread Tester Chamber Flammability Analyzer For Building Materials provides data suitable for comparing the end-use performances of essentially flat materials, composites, or assemblies, which are used primarily as the exposed surfaces of walls and ceilings.
Application:
Building Materials
Rail
Standard:
>>> BS 476-7---Fire tests on building materials and structures. Method of test to determine the classification of the surface spread of flame of products
Specification:
1, Surface Flame Spread Tester Chamber Flammability Analyzer For Building Materials consists of a radiation panel mounted vertically in a surround and supported on a framework.
2, The radiation panel is sullied with a gas-air mixture.
3, The radiation panel is 850mm square for a porous refractory type burner block designed to give efficient combustion of the air-gas-air mixture, with no flaming occurring on the face of the panel under operational conditions.
4, The radiation panel and its surround are supported on a framework so that the center of the panel is about 1250±100mm above floor level.
5, A specimen holder and a pilot flame arrangement mounted to one side of the apparatus.
6, The specimen holder comprises a water-cooled steel frame with water-cooled face plates. The face plates overlap the specimens by 20±2mm on their top and bottom edges and over the vertical edge adjacent to the radiation panel.
7, A spring-loaded clamp is positioned to clamp the specimen against the face plates.
8, The portable water supply to the specimen holder ensures the maximum temperature does not exceed 35ºC at the outlet from the specimen holder.
9, The specimen holder assembly is located at 90±2° to the face of the radiation panel and in such a way that the faces of the top and bottom guides of the specimen holder are in the same plane as the inside face of the surround to the radiation panel.
10, The height of the specimen holder is hinged to allow it to be swung horizontally, away from the face of the radiation panel between tests, from the test position to the standby position, and vice-versa.
11, The pilot burner consists of a steel tube.
12, The gas and air supply lines to the radiation panel contain flow meters, pressure regulators, control valves, and safety devices.
13, Heat Flux Meter: Range : 0 ~ 50 kw/m2; Surface emissivity : 0.95±0.05.
14, Dummy calibration board with holder, calibrated heat flux meter, and mounting.
