0.5m³ Flammability Testing Equipment,
IEC 60695 Needle Flame Tester
IEC 60695 Flammability Testing Equipment Needle Flame Tester With 7 Inch Color Touch Screen
The burner to produce the test flame shall consist of a tube at least 35 mm long with a bore of 0,5 mm ± 0,1 mm and an outer diameter not exceeding 0,9 mm.
NOTE The tubing specified in ISO 9626 [1 ] 2 (0,8 mm normal walled or thin walled) meets the requirements in this standard for an internal diameter of 0,5 mm ± 0,1 mm and an outside diameter no greater than 0,9 mm.
The burner is supplied with butane or propane gas having a purity of at least 95 %. There shall be no air admitted to the burner tube.
With the axis of the burner in the vertical position, the gas supply is adjusted so that the length of the flame is 1 2 mm ± 1 mm, when viewed in subdued light against a dark background (see Figure 1 a). The flame shall be confirmed using the apparatus and procedure detailed in Annex A. The test time for the temperature to increase from 1 00 °C ± 5 °C to 700 °C ± 3 °C shall be 23,5 s ± 1 ,0 s.
5.3 Laboratory fumehood/chamber
The laboratory fumehood/chamber shall have an inside volume of at least 0,5 m 3 . The chamber shall provide a draught-free environment, whilst allowing normal thermal circulation of air past the test specimen. The chamber shall permit observation of the test in progress.
The inside surfaces of the walls shall be of a dark colour.
For safety and convenience, it is desirable that this enclosure (which can be completely closed) be fitted with an extraction device, such as an exhaust fan, to remove products of combustion, which may be toxic. The extraction device shall be turned off during the test and turned on immediately after the timing measurements have been made. A positive closing damper may be needed.
NOTE Placing a mirror in the chamber, to provide a rear view of the test specimen, has been found to be useful.
5.4 Specified layer
To evaluate the possibility of spread of fire, for example by burning or glowing particles falling from the test specimen, a layer of the material or components normally surrounding or situated underneath the test specimen is placed underneath the test specimen at a distance equal to the distance between the test specimen and the surrounding material or components when the test specimen is mounted as in normal use.
If the test specimen is a sub-assembly or a component of the equipment and is tested separately, a piece of flat smooth wooden board, approximately 1 0 mm thick covered in close contact with a single layer of wrapping tissue, is positioned at a distance of 200 mm ± 5 mm below the place where the needle-flame is applied to the test specimen, unless otherwise specified in the relevant specification. Wrapping tissue as specified in 4.21 5 of ISO 4046-4 is
a soft and strong, lightweight wrapping tissue 1 2 g/m 2 to 30 g/m 2 .
If the test specimen is a complete free-standing equipment, it is placed in its normal position of use on the tissue covered wooden board, extending for a minimum of 1 00 mm outside the base of the equipment in all directions.
If the test specimen is a complete wall-mounted equipment, it is fixed in its normal position of use 200 mm ± 5 mm above the tissue covered wooden board.
Means to fix the test specimen and the burner in position may be necessary.
5.5 Timing device
The timing device shall have a tolerance of not more than 0,5 s.
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.
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.
