IEC60695-11-5 Flammability Testing Equipment Needle-Flame Tester With Electrical Control And Button Operation

Standard:

IEC 60695-11-5 Fire hazard testing – Part 11 -5: Test flames – Needle-flame test method – Apparatus, confirmatory test arrangement and guidance.

Description of the test apparatus:

• Burner:

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.

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.

• Flame:

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.

• Laboratory fumehood/chamber:

The laboratory fumehood/chamber shall have an inside volume of at least 0.5 m³. 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.
