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.<\/p>\n

The needle flame test apparatus utilizes a needle-shaped burner with a specified size (\u03a60.9mm) and is fueled by a specific gas (butane or propane). The burner is oriented at a angle of 45\u00b0 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.<\/p>\n

What is a needle flame test?<\/a><\/strong>
\nThe full name of IEC 60695-2-2\u00a0is Fire hazard testing Part 2: Test methods \u2013 Section 2\u00a0Needle-flame test<\/strong><\/a>. It was prepared by IEC technical committee 89: Fire hazard testing. The following is the related introduction of IEC 60695-2-2 Scope.<\/p>\n

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.<\/p>\n

What is flame retardant test methods?<\/a><\/strong>
\nIn the case of horizontal\u00a0needle flame test<\/strong> 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\u00b11S 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.
