        UL 94 Horizontal and vertical flame test apparatus BND-SPR

        The horizontal and vertical burning test mainly refers to UL 94-2006, IEC 60695-11-4, IEC 60695-11-3, GB/T5169-2008 series and other standards, using Bunsen burner of specified size and specific gas source (Methane or propane), according to a certain flame height and a certain flame angle, the test sample in a horizontal or vertical state is regularly burned several times, and its flammability is evaluated by the duration and burning length of the test sample‘s ignition and burning. Sex and fire hazard.
        Description

        Product Description:

        Name:UL 94 Horizontal and vertical flame test apparatus

        Type:BND-SPR


        The Basic introduction of the flame tester:

        1. The horizontal and vertical burning test mainly refers to UL 94-2006, IEC 60695-11-4, IEC 60695-11-3, GB/T5169-2008 series and other standards, using Bunsen burner of specified size and specific gas source (Methane or propane), according to a certain flame height and a certain flame angle, the test sample in a horizontal or vertical state is regularly burned several times, and its flammability is evaluated by the duration and burning length of the test sample's ignition and burning. Sex and fire hazard.

        2. HVR-4 horizontal and vertical combustion tester is mainly used for grading assessment of the flammability of V-0, V-1, V-2, HB, and 5V materials. It is suitable for the research, production and quality inspection departments of electrical and electronic products and their components such as lighting equipment, low-voltage electrical appliances, household appliances, machine tool electrical appliances, motors, power tools, electronic instruments, electrical meters, electrical connectors and accessories. Used in insulation materials, engineering plastics or other solid combustible materials industries.
