KP8011 5 va/vb plastic vertical burning test machine (500 w flame tester)
1. Scope of application:
Suitable for solid materials and performance equal to and greater than 250 kg/M3 density foam. Requires the use of two different shape test samples in characterization of the properties of rectangular bar of the test sample to evaluate the flammability and combustion time of material, rectangular test sample to evaluate the ability of resistance to burn through the material.
2. Standard:
Conform to GB/T5169.17-2008 "500 w flame test methods", IEC60695-11-20 of UL94 5 va and vb, ASTM D 5048, ISO10351 test standard.
3. The combustion housing:
Enclosure: 0.75 m3, adopt CNC machine processing molding, circular modelling beautiful generous. High-quality SUS304 stainless material/painting, has the characteristics of beautiful and rust corrosion.
Breeze for the box body at the top of the exhaust system, the test is completed, will waste gas exhaust to the outside; During the trial, this system is to stop state.
Enclosure front in the process of the test can be sealed toughened glass observation window, convenient for observation test.
Illuminometer: the casing of the intensity of illumination < 20 lx
