The ZY-3 Needle Flamp 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 angle of 45° 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.

Standard:
IEC 60695-2-2:2021 “Fire hazard testing – Part 2: Test methods – Section 2: Needle-flame test”
