Noise insulation materials combustion and flame propagation characteristics experiment method1 ScopeThis standard specifies the test method for noise insulation material is exposed to radiation heat and flame flammability and flame spread characteristics. This standard applies to the assessment of heat insulation material flammability and flame spread properties.2 Terms and DefinitionsThe following terms and definitions apply to this standard. 2.1 Flame spread flamepropagation Visible flame spread along the length of the sample direction most remote. NOTE. measured from the center of the combustion flame source. After the initial ignition, the flame goes out on all the sample prior to measurement of the distance, and after the test measurements charred Length is different. 2.2 Noise insulation materials thermal/acousticinsulationmaterial Thermal barrier and (or) material or material system sound. Example. Foam and glass fiber coated with a film or other flocculent material. 2.3 Zero zeropoint The point of contact with the burner flame specimen.3 Test Equipment3.1 radiation plate chamber Radiation plate chamber shown in Figure 1. Radiation plate chamber should be long (1397 ± 3) mm, width (495 ± 3) mm, higher than the sample 710mm ~ 762mm closure device. Side walls, the bottom and top plates should be insulated as fibrous ceramic insulation. Front panel should be set up There is a non-ventilated, high temperature glass window for observation during the test specimen. Settings window for a door at the specimen level movable Out of the station. The bottom of the chamber should be sliding steel platform, to ensure that the sample holder is fixed and horizontal position. The test chamber And a radiant heat source should be built opposite end of the chimney, the exterior dimensions of length (423 ± 3) mm, width (139 ± 3) mm, height (330 ± 3) mm, Internal dimensions should be longer (395 ± 3) mm, width (114 ± 3) mm. Chimney should extend to the top of the chamber (see Figure 2). ......Tips & Frequently Asked Questions:Question 1: How long will the true-PDF of GB/T 25353-2010_English be delivered?Answer: Upon your order, we will start to translate GB/T 25353-2010_English as soon as possible, and keep you informed of the progress.
