ANNEX

1. (1) SCOPE

These provisions relate to fluorescent lighting luminaires fitted with starters.

The provisions of Items 2.2 et sec. shall apply to luminaires for residential areas. Unsuppressed luminaires shall be subject only to the labelling requirements of Item 2.1.

2. GENERAL REQUIREMENTS 2.1. Labelling of unsuppressed luminaires

The words "unsuppressed luminaire for use in non-residential areas" must be affixed to the luminaire. These words shall be used until the Committee on adaptation to technical progress has settled on an alternative.

Note:

The definition of non-residential areas is a matter for the competent national authority.

2.2. Minimum values of insertion loss

The minimum values of insertion loss shall be met by at least 80 % of series-produced luminaires with 80 % confidence.

Methods of application of the minimum values of insertion loss are shown in Item 7.

3. DEFINITIONS

For the purpose of this Annex, the definitions contained in IEC publication 50(902) - 1973 edition - International electrotechnical vocabulary (IEV), Chapter 902 : Radio interference, apply.

4. LIMITS 4.1. Insertion loss of switch-start fluorescent lamp luminaires

For luminaires for tubular fluorescent lamps connected to electrical supplies feeding dwellinghouses in the voltage range 100 V/250 V between poles or to earth the minimum value of the insertion loss shall be 28 dB in the frequency range 150 to 160 kHz, 28 dB at 160 kHz decreasing linearly with the logarithm of the frequency to 20 dB at 1 400 kHz, and 20 dB in the frequency range 1 400 to 1 605 kHz.

The requirements do not apply to luminaires in which the lamps are powered at a frequency in excess of 100 Hz or to luminaries for which no method of measurement is defined in Item 5.

The limits apply throughout the frequency range and therefore the interference characteristics shall be assessed throughout. (1) Point 1 of the Annex to Council Directive 76/890/EEC.

Note:

An initial survey or scanning of the complete range shall be made and the registered values shall be given at least at the following preferred frequencies and at all frequencies at which there is a minimum below the limits : 160, 240, 550, 1 000 and 1 400 kHz.

>PIC FILE= "T0045361"> 4.2. Measurements of luminaires which cannot be measured with the methods defined in Item 5

Luminaires which cannot be measured using the methods defined in Item 5 (for example, when it is impossible to replace the lamp by a dummy lamp, or when an electronic starter is incorporated) are subject to the requirements of Directive 76/889/EEC in the frequency band from 0 715 to 30 MHz.

5. METHODS OF MEASUREMENT OF THE INSERTION LOSS OF LUMINAIRES 5.1. Circuits for the measurement of the insertion loss 5.1.1. Luminaires used for linear lamps with a nominal diameter (1) of 25 or 38 mm.

The insertion loss is measured in the circuit as shown in Figure I with dummy lamps as specified in Item 5.4 and Figure 4a.

In the case of lamps which have a nominal diameter of 25 mm, but which are interchangeable with lamps having a nominal diameter of 38 mm, the measurement of insertion loss shall be made with a dummy lamp with a nominal diameter of 38 mm, unless the manufacturer's instructions prescribe the exclusive use of a 25 mm diameter lamp.

For luminaires which can be operated only with lamps having a nominal diameter of 25 mm, insertion loss measurements are performed with a dummy lamp for the nominal diameter of 25 mm. (1) According to the most recent version of IEC publication 81.

>PIC FILE= "T0045362"> Note:

When measuring U-type fluorescent lamp luminaires the same circuit arrangement is to be used, but the linear dummy lamp shall be replaced by the U-type dummy lamp.

5.1.2. Luminaires used for circular lamps with a nominal diameter (1) of 28 or 32 mm.

The insertion loss is measured as shown in Figure 2.

(1) According to the most recent version of IEC publication 81. >PIC FILE= "T0045363"> 5.1.3. Luminaires used for lamps other than those mentioned in Items 5.1.1 and 5.1.2. The insertion loss is measured as shown in Figure 2a.

>PIC FILE= "T0045364"> Note:

When measuring non-linear luminaires the same circuit arrangement is used, but the linear dummy lamp is to be replaced by a dummy lamp having the same dimensions as the original lamp.

5.1.4. For the methods given in Items 5.1.1, 5.1.2 and 5.1.3 the following conditions apply: 5.1.4.1. When the luminaire incorporates more than one lamp, each lamp is replaced in turn by the dummy lamp.

The insertion loss of multi-lamp luminaires in which the lamps are powered in parallel shall be measured for each lamp and the minimum value of insertion loss measured shall be used for comparison with the limit.

5.1.4.2. >PIC FILE= "T0045365">

5.1.4.3. When starters having integral capacitors are used, as is usually the case, the starter is removed and replaced by a test capacitor of 5 000 pF ± 10 %.

However, in cases where the manufacturer fits a capacitor external to the starter and gives a warning against the use of an additional starter capacitor, the original capacitor is retained and no test capacitor is added.

Care shall be taken to ensure that the test capacitor maintains its characteristics over the whole frequency range covered by the measurement.

With the exception of this possible modification and the replacement of the lamps, the luminaire is measured as manufactured.

5.1.4.4. If the luminaire has a frame of insulating material, the back of the luminaire shall be placed on a metal sheet, to be connected to the reference earth of the artificial mains V-network VN

5.2. Measurement procedure 5.2.1. The insertion loss is established by comparing the voltage U1 of the measuring receiver, obtained by connecting the output terminals of the transformer to the terminals of the artificial mains network, with the voltage U2 obtained when the transformer is connected to the artificial mains V-network through the luminaire to be measured.

5.2.2. >PIC FILE= "T0045366">

5.2.3. The voltage U1 (about 2 mV) measured between a' or b' and earth shall be independent of the two positions of the switch of VN.

5.2.4. The voltage U2 measured with the luminaire connected may have different values and therefore may depend on the two positions of the switch of VN ; the higher of them shall be retained as representative.

5.2.5. The insertion loss is given by: >PIC FILE= "T0045367">

5.2.6. Where it is known that the insertion loss measured according to Figure 1, or for series-operated lamps according to Item 5.1.4.2, is a minimum for a given orientation of the dummy lamp(s), measurements may be made for this orientation only (e.g. for a luminaire with a single ballast and with the dummy lamp(s) inserted so that the relevant input terminal is directly connected to the neutral supply terminal of the luminaire). In cases where there is any doubt on this point, measurements shall be made for all possible orientations of the dummy lamp(s).

5.3. Balance-unbalance transformer

The balance-unbalance transformer, as depicted in the circuits of Figure 1, 2 and 2a, is used to obtain a symmetrical output voltage from the radio-frequency generator. 5.3.1. The essential requirements are: - the capacity between the secondary and the primary of the transformer must not be greater than 5 pF,

- the primary is connected to the metal box which encloses the device,

- >PIC FILE= "T0045368">

>PIC FILE= "T0045369"> 5.3.2. Connection of the transformer to the dummy lamp or the tube must be made with unscreened leads not exceeding 10 cm in length.

5.3.3. Figure 3 gives an example of a circuit and the construction of a suitable transformer (mechanical construction and electrical circuit).

>PIC FILE= "T0045370">

>PIC FILE= "T0045371"> 5.4. Dummy lamps

The dummy lamps used in the circuits of Figures 1 and 2 simulate the r.f. properties of the lamp and are shown in Figures 4a and 4b.

When the dummy lamp is mounted in the luminaire it shall remain parallel to the metalwork of the luminaire. Any support necessary to achieve this must not appreciably alter the capacitance between the dummy lamp and luminaire.

Note:

Preliminary measurements can be performed using normal lamps provided with an external conductive coating. The length of the conductive coating equals the length measured cap-face to cap-face of the lamp minus 150 mm. This coating shall be symmetrically disposed.

(6.)

7. APPLICATION OF MINIMUM VALUES OF INSERTION LOSS IN TESTS FOR CONFORMITY OF LUMINAIRES IN SERIES PRODUCTION 7.1. Tests shall be made: 7.1.1. either on a sample of luminaires of the type, using the statistical method of evaluation set out in Item 7.3

7.1.2. or, for simplicity's sake, on one luminaire only.

7.2. Subsequent tests are necessary from time to time on luminaires taken at random from production, especially in the case indicated in Item 7.1.2. In the case of any dispute which could lead to a ban on sales, such a ban shall be considered only after tests have been carried out in accordance with Item 7.1.1.

7.3. Statistical assessment of compliance shall be made as follows:

This test shall be performed on a sample of not less than five, and not more than 12 items of the type, but if in exceptional circumstances five items are not available, then a sample of three or four shall be used. Compliance is achieved when the following relationship is met: >PIC FILE= "T0045372">
