Needle Flame Test

According to IEC60695-2-2, IEC60695-11-5, IEC62368-1 and GB/T-5169.5, ZY-3/ZY-3S needle flame test equipment is applied in the production and quality control department of lighting products, hyperpiesia electrical apparatus, domestic appliance, machine electric appliance, electrical machine, power tool, electronic instrument, electrician instrument and technical equipment. Also, the apparatus is suitable for the industry of insulation material, engineering plastics and solid combustible material.

Specifications:
? 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 (gauge is included)
? Gas: 95% butane
? 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

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.
