Horizontal and vertical flammability tester is mainly used to measure the combustion performance of plastic, rubber or film under the specified fire source, so as to judge its fire resistance level. It is not only suitable for the research, production and quality inspection departments of electrical and electronic plastic or rubber products such as lighting equipment, low-voltage electrical appliances, household appliances, motors, tools, instruments and electrical connectors and their components, but also for insulating materials, engineering Plastic, firestop material type approval or other solid combustible material Technical Parameters: Calibration purpose and requirements The calibration of the test flame is the most basic guarantee for the test to ensure the reliability of the test. The test requires a 50w flame height of 20±1mm, the outer yellow flame height of the 500w flame is 125mm, and the inner blue flame height is 40mm; use the flame to heat the copper block, and the time ...
