Radiant panel test

Applications. In this test, the flammability of materials is considered as a function of the heat release rate and critical ignition energy. Flammability is inversely proportional to ignition energy and directly proportional to heat released.  [Pg.580]

Artificial surfaces must be resistant to cigarette bums, vandaUsm, and other harm. Fire resistance is most critically evaluated by the NBS flooring radiant panel test (10). In this test, a gas-fired panel maintains a heat flux, impinging on the sample to be tested, between 1.1 W/cm at one end and 0.1 W/cm at the other. The result of the bum is reported as the flux needed to sustain flame propagation in the sample. Higher values denote greater resistance to burning results depend on material and surface constmction. Polypropylene turf materials are characterized by critical radiant flux indexes which are considerably lower than those for nylon and acryflc polymers (qv) (11). [Pg.534]

Figure 2. The Radiant Panel Test was designed to measure both critical ignition energy and rate of heat release. A sample is mounted facing a controlled heat flux but at a 3CP angle to it such that the upper part of the specimen is more severely exposed. Since irradiance decreases down the specimen, the time progress of ignition down the specimen serves to measure central ignition energy. Thermocouples in the stack above the specimen serve as a measure of heat release rate. Figure 2. The Radiant Panel Test was designed to measure both critical ignition energy and rate of heat release.

In terms of fire safety, there are no fire resistance requirements and all interior surfaces must comply with the FSI of 200 in the Steiner tunnel test, ASTM E 84,114 or a radiant panel index of 200 in the radiant panel test, ASTM E 162.55 Thermal insulation materials, other than foam plastics, must meet an ASTM E 84 Class A requirement (i.e., FSI < 25 and SDI < 450) and loose-fill insulation must meet the same requirements as the building codes, which are mostly based on smoldering tests (as the materials tend to be cellulosic). Foam plastic insulation must be treated as in the building codes as well (see Table 21.13) it cannot be used exposed (expensive foam that meets the NFPA 286 test is not used in manufactured housing) and must meet an ASTM E 84 Class B requirement behind the thermal barrier. [Pg.637]

Setchkin) of 535 C and UL rating of V-0. Flame spread in the radiant-panel test is low (I, = 2.7) and the LOI is high — 47. NBS smoke-chamber results show a low specific optical density (Ds 4 min = 0.7, Dm = 31, flaming mode), and combustion-product-toxicity studies show results comparable to polystyrene (10). [Pg.228]

This is called the Radiant Panel Test. A Flame-Spread Index is calculated as a product of the flame-spread and heat-evolution factors. Smoke density is also obtained. [Pg.418]

In the Flooring-Radiant-Panel-Test of ASTM D 648-1978, a horizontally placed specimen of 230 mm x 1050 mm is exposed to a radiating body oriented at 30 deg. to the horizontal and an igniting flame. The radiation intensity at the surface of the specimen is 1.0 to 0.1 W/cm. Both heat sources operate for the first ten minutes of the test procedure until the specimen has inflamed. If not, the test is continued for another ten minutes with the radiator only. The lowest radiation intensity necessary for inflaming the specimen is determined. [Pg.199]
