UL94 Horizontal vertical flammability tester, is based on the standard ANSI/UL94, iec60950-1, iec695-2-2, GB/ t2408-2008 and developed, fully meet the standard GB/T2408 technical requirements.Both horizontal and vertical combustion of plastics can be tested on the same instrument.Compared with similar instruments, it has the advantages of high degree of automation, accurate timing, automatic test results and so on.
provides for the determination of combustion rate, flame burning time and flame free burning time of patterns placed horizontally and vertically in the laboratory after being ignited by a small flame source.
the combustion test is IEC 60950, UL94, IEC707, IEC 695-2-2, ISO1210 and other standards of the simulated safety test items.Combustion test is with specified size of the Bunsen burner (Bunsen buner) and specific gas source or natural gas (methane), according to certain flame height and the Angle of certain ShiYan sample (s) in the state of the horizontal or vertical timing applied for several times, try to light, heat of combustion duration and try under the bedding of spark ignition to assess whether their combustibility.
can protect the mobile equipment against fire.Fire protection enclosure for standing equipment;Materials installed in the fireproof enclosure;The flammability of grade v-0, v-1, v-2, HB, 5V, hf-1, hf-2, HBF or cellular plastics shall be graded and evaluated.Is suitable for lighting equipment, low-voltage electrical appliances, household appliances, machine tool electrical appliances, motor, electric tools, electronic instruments, electrical instrumentation, information technology equipment, electrical equipment, electrical fittings and accessories such as electrical and electronic products and its component parts in the research, production and quality inspection departments, can also be applied to insulation materials, engineering plastics industry or other solid combustible materials.
