  • HVR-LS Horizontal Vertical Flame Tester is designed for electrical equipment and plastic components used in horizontal and vertical flammability testing. It is primarily used for rating assessment of combustibility for HB&V grade (50W) and 5V grade (500W) materials. This tester is suitable for research, production, and quality inspection departments of electrical and electronic products, including lighting equipment, low-voltage appliances, household appliances, machine tool appliances, motors, power tools, electronic instruments, electrical instruments, electrical connectors, and accessories. It is also applicable to the insulation materials, engineering plastics, or other solid combustible materials industry. This tester is available for use in the plastic industry, inspection departments, and research institutions.

    The Horizontal Vertical Flame Tester utilizes standard specified dimensions of the test specimen and a specific gas source (methane or propane). The test is conducted by applying a timed flame at a certain height and angle of incidence to the specimen in a horizontal or vertical position. The combustibility and ignition hazard of the specimen are assessed based on factors such as ignition, duration of flaming combustion, and burning length.

    ANSI/UL94 “UL Standard for Safety Tests for Flammability of Plastic Materials for Parts in Devices and Appliances”
    IEC60695-11-3 “Fire hazard testing – Part 11-3: Test flames – 500 W flames – Apparatus and confirmational test methods”
    IEC60695-11-4 “Fire hazard testing – Part 11-4: Test flames – 50 W flame – Apparatus and confirmational test method”
    IEC60695-11-10 “Fire hazard testing – Part 11-10: Test flames – 50 W horizontal and vertical flame test methods”
    IEC695-2-2 “Fire hazard testing – Part 2: Test methods – Section 2: Needle-flame test”

    How many types of procedure are there in UL 94 flammability test?
    UL94 flammability test grade is the most widely used plastic material flammability performance standard. It is mainly a fire test standard for plastic box foam materials to evaluate the ability of materials to extinguish after being ignited. According to the burning speed, burning time, anti-drip ability and whether the dripping is burning, there are many methods to determine whether the burning of the material is divided into five test methods according to UL94 flammability test. Pls. check below:
    1. The 50W flame horizontal combustion UL94 flammability test, HB40, HB75 classification;
    2. The 50W flame vertical combustion test V-0, V-1, V-2 classification;
    3. 500W flame combustion test 5VA, 5VB classification;
    4. Vertical combustion VTM-0, VTM-1, VTM-2 classification of flexible samples of thin film materials;
    5. The foam material burns horizontally HF-1, HF-2 and HBF classification.
