1.Principle

A sampleis placed in a horizontal position and exposed to an electrical heater. Underthe sample there is a box to collect drops.

Inside thebox there is some cotton to detect if the drops are burning.

Theheating source is a heater having a power of 500 Watts. The area exposed toradiation consists of a transparent Quartz plate of an diameter of 100 mm

2.Calibration

A heatingflux measuring device （radiometer） of the Gardon foiltype with a measuring range of at least 10 W/ cm2 is used for calibration.

Thecalibration of the heating flux measuring device has to be calibrated by areference heating flux measuring device everytime the heater has to becalibrated. The reference heating flux measuring device has to be re-calibratedaccording a national standard.

3.Calibrationcheck

Theradiation density caused by the the energy impact, which has according to thecalibration a radiation density of 3 W/cm2, has to be controlled often. Atleast once every 50 hours of operation. The device has to be calibrated againif the measured values have changed more than

0.06W/cm2.

4.Procedureof calibration

The devicehas to be placed at a draught safe spot. The air velocity must not higher than0.2 m/s. The heating flux device has to be inserted into the test rig insteadof the sample. The black plate of the heating flux device must be located inthe middle of the heater.

Then thepower is turn on using the potentiometer POWER REGULATOR until the radiationdensity is 3 W/cm2 in the center of the heater surface. After the potentiometerwas adjusted to provide the value 3 W/cm2 the potentiometer should not bere-adjusted for 5 minutes to stabilize it.

5.Sample

The samplemust have the dimensions 70 mm x 70 mm.

Ifpossible the samples should be production as the ready product. If the productis thicker than 13 mm its thickness has to be reduced to 13 mm at the sideopposite to the side seen by the passengers. If this is not possible the testmust be conducted in compliance with a Technical Service with the sample havingthe regular thickness. This, however, must be stated in the report. Compositematerials are to be tested as homogeneous materials.

In case ofmaterials consisting of different layers, not classified as componentmaterials, all layers of a thickness up to 13 mm have to be tested on the sideexposed to the interieur of a vehicle. The total mass of the sample must be atleast 2 g. If the mass is below that a sufficient number of samples have to beadded.

If bothsides of the sample are different, each side has to be testesd, resulting in atest of eight samples.

Before thetest the samples and the cotton have to be conditioned at a temperature of 23 ℃

6. Doingthe calibration

1）  Remove thesample holder.

2）  Mount thecalibration ring.

3）  Connect thesensor to te amplifier.

4）  Regulate theenergy using the POWER REGULATOR potentiometer.
