  • The ZY-3 needle flame test apparatus is mainly used for testing lighting equipment, low-voltage electrical appliances, household appliances, power tools, electronic instruments, electronic meters, etc. Additionally, this instrument is also suitable for testing insulation materials, engineering plastics, and solid flammable materials. The needle flame test apparatus consists of a needle flame burner, a working chamber, and a temperature measuring device.

    The needle flame test apparatus utilizes a needle-shaped burner with a specified size (Φ0.9mm) and is fueled by a specific gas (butane or propane). The burner is oriented at a 45° angle and ignited for a predetermined time onto the test specimen, evaluating the ignition hazard of small flames caused by internal fault conditions of the equipment based on whether the test specimen and the ignition pad ignite, the duration of combustion, and the length of the flame.

    IEC60695-2-2 “Fire hazard testing – Part 2: Test methods – Section 2: Needle-flame test”
    IEC60695-11-5 “Fire hazard testing – Part 11-5: Test flames – Needle-flame test method – Apparatus, confirmatory test arrangement and guidance”
    IEC62368-1 “Audio/video, information and communication technology equipment – Part 1: Safety requirements”

    • Angle of burner: 45° (when in test) / 0° (when adjust the flame’s height)
    • Needle flame burning time: 0~999.9s±0.1s (adjustable, 30s in general)
    • After-flame time: 0~999.9s±0.1s, auto record and pause manually
    • Height of flame: 12mm±1mm
    • Gas: 95% butane (Note: Digital Barometer is option with extra cost)
    • Test range of temperature: 0~1000℃
    • The temperature rises from 100℃±2℃ to 700℃±3℃ within 23.5 seconds±1s
    • Thermocouple: Φ0.5mm K type
    • Applied with touch screen and remote control
    • Number of burning times for a single test: single or multiple times can be set
    LISUN ZY-3 needle flame tester can run multiple times flame test in a single test automatically according to the Annex S S.1 of the IEC62368-1 standard: 

    To save the delivery cost for the oversea market, LISUN designed a compact version needle flame test equipment weighing less than 50kg. (Customer need to prepare additional ventilation system for ZY-3S)

    What is a needle flame test?
    The full name of IEC 60695-2-2 is Fire hazard testing Part 2: Test methods – Section 2 Needle-flame test. It was prepared by IEC technical committee 89: Fire hazard testing. The following is the related introduction of IEC 60695-2-2 Scope.

    This section of IEC 60695-2-2 specifies a needle-flame test to simulate effect of small flames which may result from fault conditions within equipment, in order to assess by a simulation technique the fire hazard.It is applicable to electrotechnical equipment, its sub-assemblies and components and to solid electrical insulating material or other combustible materials.

    What is flame retardant test methods?
    In the case of horizontal needle flame test HB classification, the sample size is required to be 125mm in length, 13mm in width, and no more than 13mm in thickness. The sample is placed horizontally, the sample clamp is clamped to one end of the sample, and the ignition device is at a 45 degree angle to keep the flame position unchanged. Apply 30±1S to the other end of the sample holder, and place a metal mesh and a freely movable fixed frame horizontally under the sample holder, so that when the sample burns, the free end and the metal mesh are kept 10mm.
