IEC 60695 Automatic Ignition Needle Flame Resistance Testing Equipment

Usage:

Electrical and electronic products due to the use of the process of failure: such as electronic components or electronic parts of the poor contact with overload, fault current and other reasons, it may cause a fire, this instrument is to simulate the electrical and electronic products in the fault conditions under the fire caused by a small flame, come Evaluate the danger of electrical and electronic products catching fire.

Principle:

Produce a test flame and burn the test sample for a certain period of time to observe the danger of fire. The testing machine is composed of the action control part of the test box and the electrical control part:

Performance and parameters:

1, the volume of the box: ≥ 0.5m3.

2. Burner: Inner hole: 0.5mm, outer diameter: 0.9mm, length ≥ 35mm.

3, sensing temperature: 1050 °C or more.

4, temperature conductor: 6mm.

5, burning time: 0 ~ 99.99 seconds, arbitrarily set.

6, stop burning time: 0 ~ 99.99 seconds, arbitrarily set.

7, warming time: 0 ~ 99.99 seconds, arbitrarily set.

8, automatic ignition.

9, automatic combustion.

10, with flame adjustment function.

11, with a flame measurement function.

12. The burner uses butane gas, which has a purity of not less than 95% and does not allow air to enter the burner tube. Note: The burner can also use propane gas, but with butane gas as the reference gas.

General description of the test:

 If possible the sample should be a complete device or part or component. If necessary, remove part of the housing or cut off the appropriate part for testing, but care must be taken to ensure that the test conditions are in terms of shape, air circulation, thermal stress effects and possible flames, and burning or hot particles falling near the test sample. There is no significant difference between the impact and the situation that occurs during normal use.

 If the test cannot be performed on a complete test sample, the appropriate part can be taken as a test sample.

 If the test sample is an appropriate part taken from a large part, care must be taken to ensure that the test flame must be applied correctly in this particular application, for example by not applying the test flame to the edge resulting from the cut.
