Thermal Release Rate Platform Horizontal Flammability Tester Full Size Multi Function
Scope of application:
Products are suitable for wall inner surface and the ceiling surface, especially for some reason (insulating substrate. Seams. The larger the effects of irregular surface), can in laboratory scale test of products, such as thermoplastic material.
Meet the standard:
Compliance with GB/t25207-2010 "fire test method of real room fire test" standard;
Comply with ISO 9705-1993 "fire test." standard of indoor articles on fire test.
ISO 9705-1993 fire tests. Full scale room test for surface products
Main parameters:
The whole system consists of three parts: standard combustion chamber. Large calorimeter and data acquisition and processing system
Standard combustion chamber: using brick and masonry structure, the indoor wall surface and top face are respectively attached with 15mm refractory glass second cotton. Built in a non-mechanical ventilation. Heat insulation and large enough room to ensure no impact on the lab.
The center of the north wall of the combustion chamber has a gate of 0.8m-wide x2m, and a 2m x2m viewing window on the east wall.
An electron is placed at the geometry center of the combustion chamber. The measuring range is 0--500 kg, and the measurement accuracy is 0.001kg, which can be used to measure the loss of the combustor during the combustion process.
Southwest corner of the room set up total fire, firearms, the total fire use square openings of gas total firearms within the total is divided into two layers, the lower is the grit, the upper is fine sand, separated with wire mesh in the middle
During the test, the combustion of the sample and the combustion products are discharged from the exhaust pipe.
Carbon monoxide range: 0-1%, measuring accuracy plus or minus 0.1%
Carbon dioxide (CO2) measurement range 0-10% and repeatability < 1%;
High precision pressure regulating valve, adjusting standard pressure;
The glass rotor flowmeter regulates the flow of combustion jet.
Smoke density: light source, halogen lamp, convex lens, silicon photocell 4
Temperature measurement: 5m thermoelectric pot 7, 0.25mm thermoelectric pot 5.
