Needle Flame Test Apparatus For Fire Hazard Testing Touch Screen Operation

Needle-Flame Test Apparatus For Fire Hazard Testing - Touch Screen Operation

Introduction:

The best method for testing electrotechnical products with regard to fire hazard is to duplicate exactly the conditions occurring in practice. In most instances this is not possible.
Accordingly, for practical reasons, the testing of electrotechnical products with regard to fire hazard is best conducted by simulating as closely as possible the actual effects occurring in practice.                 Flammability Testing Equipment
Parts of electrotechnical equipment which might be exposed to excessive thermal stress due to electric effects, the deterioration of which might impair the safety of the equipment, should not be unduly affected by heat and by fire generated within the equipment.
Parts of insulating material or of other combustible material which are liable to propagate flames inside the equipment may be ignited by flames produced by a failing component.        Flammability Testing Equipment
Under certain conditions, for example a fault current flowing over a tracking path, overloading of components or parts and bad connections, flames may also occur; such flames may impinge upon combustible parts in the vicinity.

Standard:IEC60695-11-5 Test flames-Needle-flame test method-Apparatus,confirmatory test arrangement and guidance

Application:This part of IEC60695 specifies a needle-flame test to simulate the effect of a samll flame which may result from fault condition, in order to assess by a simulation technique the fire hazard.

Test sample:Lighting, low-voltage electrical appliances, household appliances, machine tool electric appliance, electric motor, electric tools, electronic instruments, electrical instruments, electrical connector, such as electrical and electronic equipment and parts, components, including insulation materials, engineering plastic or other solid combustible materials.                          Flammability Testing Equipment

Feature:The Needle Flame Tester consists of a Ф0.9mm needle-shaped burner that tilts with the angel of 45°and provide it with butane gas. The fire hazard of the equipment when there is flammule inside the equipment that caused due to the fault condition is assessed by whether the specimen can be ignited or the combustion time and length.
