Qingdao Zhongbang Instrument Co., Ltd. professionally produces hard hat flame retardant performance tester based on the new national standard of the helmet GB/T2812-2006 "hard hat test method" developed for flame retardant performance test of the helmet, high degree of automation, easy operation , Widely used in hard hat manufacturing enterprises, major quality inspection units and construction engineering inspection stations.
Instrument Aliases: flame retardant tester helmets, helmets flame instrument, instrument combustion helmets, helmets flame retardant tester, tester helmet flame retardant <br> <br> Second, the instrument characteristics
1. Using electronic ignition, safe and convenient, "push-pull" sample holder fixture, "positioning wire" and "guide" assisted positioning.
2, burner automatic timing positioning.
3, ignition time 0-99.9 seconds arbitrarily set, continue burning time, smoldering time are automatically recorded, digital display.
4, equipped with highly sensitive combustible gas leakage alarm device, if found flammable gas alarm and automatically cut off gas.
5, fuel supply device: pressure regulating valve, gas volume control valve, gas tank device, to ensure that the flame-spraying head to discharge a 50mm-length blue flame.
6, the height of the flame can be adjusted, there is a flame height gauge to measure the height of the auxiliary flame height.
Third, the main technical indicators
1. Time timer: The displayed value is ±1% error, used to record the continuous burning time, accurate to 0.01s.
2, the flame application timer: display error ± 1%, used to set the flame on the helmet on the time, burning time can be set by itself, ignition timing range: 0-99.99 seconds.
3, equipped with flame height measuring device: ruler height 50mm.
4, ignition time 0-99.9 seconds arbitrarily set, automatically record the continued burning time, smoldering time.
5, flame height measurement device: ruler height 50mm.
6, the flame spray head: horizontal fuel nozzle, internal diameter 10mm.
7, Bunsen burner internal diameter 10mm ± 0.10mm.
8, gas source: methane, propane, butane, liquefied petroleum gas.
9, the ambient temperature: -10 °C -30 °C.
10. Relative humidity: ≤85%.
Fourth, meet the standard
The helmet flame retardant complies with the national standard GB/T2812-2006 "Test method for helmets"
