Standard vertical burning tester for a V-0, V-1, V-2, HB, 5V of the VMT grade material combustible grading assessed. Research, production and quality control departments for lighting equipment, low voltage electrical appliances, household appliances, electrical machines, motors, power tools, electronic equipment, electrical instruments, electrical fittings and accessories such as electric and electronic products and their component parts, also applies insulation, plastic or other solid combustible materials industries.
Standard:
Meet the the IEC60950, UL94, IEC707, IEC60695-11-10/-20, ISO1210, GB/T5169.16 and 17, GB4943, GB/T2408-1996 standard specifies the analog security test project.
Basic principles:
When the product around the fire, you should ensure that will not cause a fire to spread. The required size of the Bunsen burner (Bunsen burner) and specific gas source (methane, or natural gas), certain flame height and certain facilities flame angle of the test was horizontal or vertical timing facilities burning several times to try Commodities ignited, hot combustion duration and burn length to assess its flammability and the risk of ignition.
Main features:
Tester from the test section and control section uses the integrated design, easy on-site installation and commissioning. The test chamber housing and the important parts are made of stainless steel, resistant smoke, gas corrosion.
High degree of automation of the control system with automatic ignition during the test is the test product to automatically follow the flame function in both vertical and horizontal directions. The temperature and time of the digital display, observed and recorded convenient, reliable use.
U-tube differential manometer (Dwyer), with U.S. imports placed directly on the surface of the device, convenient and aesthetic, easy to operate.
For the convenience of a single operation, configuration-wire switch can automatically control the trial began, afterflame time, I blanch time.
Bunsen burner burning lamp can be adjusted 0-45 degrees angle, and with the corresponding angle indication.
Using standard explosion-proof lamps, lighting experiment warranty does not communicate with the outside world, in line with standard experimental requirements.
With a level of combustion fixture, vertical burning fixture and the flexible the test fixture, The flexible clamp made of high quality rail can be up and down, back and forth, left and right adjustment.
Automatic or manual control, several tests can guarantee continuous automatic
Using imported ammeter, time relays and counters, and other components of domestic brand-name
