ECE R99 Gas Discharge Light Sources Approval

EUROLAB laboratory provides testing and compliance services within the scope of ECE R99 standard. The ECE R99 test regulation covers the ballast used for type approval of the light source, marking with the type and brand identification, rated voltage and wattage as specified in the relevant lamp data sheet, if the ballast is not integrated with the light source.

Test voltage means testing the voltage at the input terminals of the ballast or at the terminals of the light source, if the ballast is integrated with the light source, for which the electrical and photometric properties of the gas discharge light source are intended.

The objective value is the design value of an electrical or photometric property. When the gas discharge light source is energized by the ballast, optionally integrated with the light source and operated at test voltage, it will be achieved within the specified tolerances.

In the case of a colored (external) bulb, after 15 hours of operation with the ballast or the ballasted light source integrated into the test voltage, the surface of the bulb should be gently wiped with a cotton cloth dipped in the mixture. 70 volume percent n-heptane and 30 volume percent toluene. After approximately five minutes, the surface will be visually inspected. It should not show any noticeable change.

The measurement should be made after aging with the light source supplied by the ballast at the test voltage or the light source with the ballast integrated into the test voltage. The measurement should be made after aging with the light source supplied by the ballast at the test voltage or the light source with the ballast integrated into the test voltage.

The arc junction point to the electrode closest to the reference plane should be located in the area defined by a1 and b1. The arc junction point to the electrode farthest from the reference plane should be located in the area defined by a2 and b2.

This test is used to determine the shape of the arc and its position relative to the reference axis and reference plane by measuring its bending and diffusion in the section at a distance of 18,0 mm from the reference plane.

In case the ballast is not integrated with the light source, all tests and measurements will be made relative to the ballast. The power supply used for the start-up and operating tests of this code must be capable of providing a rapid rise of the high-current pulse.
