2.1.2.   Gas-discharge light sources of different ‘types’(1) are gas-discharge light sources within the same category which differ in such essential respects as:

2.1.2.1.

trade name or mark; that means:

(a) Gas-discharge light sources bearing the same trade name or mark but produced by different manufacturers are considered as being of different types.

(b) Gas-discharge light sources produced by the same manufacturer differing only by the trade name or mark may be considered to be of the same type;

2.1.2.2.

bulb and/or cap design, in so far as these differences affect the optical results;

2.2.   Application for approval

2.2.1.   Application for approval shall be submitted by the owner of the trade name or mark, or by his duly accredited representative.

2.2.2.   Every application for approval shall be accompanied (see also paragraph 2.4.2) by:

2.2.2.1.

drawings in triplicate, sufficiently detailed to permit identification of the type;

2.2.2.2.

a technical description including ballast identification;

2.2.2.3.

three samples of each colour which has been applied for;

2.2.2.4.

one sample of the ballast.

2.2.3.   In the case of a type of gas-discharge light source differing only by the trade name or mark from a type that has already been approved it shall be sufficient to submit:

2.2.3.1.

a declaration by the manufacturer that the type submitted is identical (except in the trade name or mark) to and has been produced by the same manufacturer as, the type already approved, the latter being identified by its approval code;

2.2.3.2.

two samples bearing the new trade name or mark.

2.2.4.   The Competent Authority shall verify the existence of satisfactory arrangements for ensuring effective control of the conformity of production before type approval is granted.

2.3.   Inscriptions

2.3.1.   Gas-discharge light sources submitted for approval shall bear on the cap or bulb:

2.3.1.1.

the trade name or mark of the applicant;

2.3.1.2.

the international designation of the relevant category;

2.3.1.3.

the rated wattage; this need not to be indicated separately if it is part of the international designation of the relevant category;

2.3.1.4.

a space of sufficient size to accommodate the approval mark.

2.3.2.   The space mentioned in paragraph 2.3.1.4 shall be indicated in the drawings accompanying the application for approval.

5.   

Supply voltage

All tests shall be carried out at test voltage as indicated on the relevant data sheet.

6.   

Starting test

The starting test shall be applied to light sources which have not been aged and have not been used for a period of at least 24 hours prior to the test.

7.   

Run-up test

The run-up test shall be applied to light sources which have not been used for a period of at least 1 hour prior to the test.

8.   

Hot restrike test

The light source shall be started and be operated with the ballast at test voltage for a period of 15 minutes. Then the supply voltage to the ballast shall be switched off for a switch-off period as indicated on the relevant data sheet and be switched on again.

9.   

Electrical and photometric test

Before any measurement, the light source shall be stabilized for a period of 15 minutes.

10.   

Colour

The colour of the light source shall be measured in an integrating sphere using a measuring system which shows the CIE chromaticity co-ordinates of the received light with a resolution of ± 0,002. The following figure shows the colour tolerance area for colour white and the restricted tolerance area for the gas-discharge light sources D1R, D1S, D2R, D2S, D3R, D3S, D4R and D4S.

ANNEX 5

Optical setup for the measurement of the position and form of the arc and of the position of the electrodes(1)

The gas-discharge light source shall be positioned as shown:

 

in figure 1 or figure 2 on sheet DxR/1 or sheet DxS/1;

 

in figure 3 or figure 4 on sheet DxR/2 or sheet DxS/2.

[Bild bitte in Originalquelle ansehen]

An optical system shall project a real image A' of the arc A with a magnification of preferably M = s'/s = 20 on a screen. The optical system shall be aplanatic and achromatic. In the focus-length f of the optical system a diaphragm d shall cause a projection of the arc with nearly parallel observation directions. To get the angle of the half divergence not larger than μ = 0,5°, the diameter of the focus-diaphragm with respect to the focus-length of the optical system shall be not more than d = 2f tan(μ). The active diameter of the optical system shall be not more than:

D = (1 + 1/M)d + c + (b1 + b2)/2 (c, b1 and b2 are given on sheet DxS/5, respectively sheet DxR/5).

A scale on the screen shall enable to measure the position of the electrodes. The calibration of the arrangement advantageously can be done by using a separate projector with a parallel beam in connection with a gauge whose shadow is projected to the screen. The gauge shall show the reference axis and the plane parallel to the reference plane and at distance ‘e’ mm from it (e = 27,1 for D1R, D1S, D2R, D2S, D3R, D3S, D4R and D4S).

In the plane of the screen a receiver has to be mounted movable in a vertical direction on a line corresponding to the plane at ‘e’ from the reference plane of the gas discharge light source.

The receiver shall have the relative spectral sensitivity of the human eye. The size of the receiver shall be not more than 0,2 M mm in the horizontal and not more than 0,025 M mm in the vertical direction (M = the magnification). The range of measurable movement shall be such that the required measures of the arc bending r and arc diffusion s can be measured.

(1)  This method is an example of a measurement method; any method with equivalent measurement accuracy may be used.

ANNEX 6

Minimum requirements for quality control procedures by the manufacturer

1.   GENERAL

The conformity requirements shall be considered satisfied from a photometric (including UV-radiation), geometrical, visual and electrical standpoint if the specified tolerances for production gas-discharge light sources in the relevant data sheet of Annex 1 and the relevant data sheet for the caps are met.

2.   MINIMUM REQUIREMENTS FOR VERIFICATION OF CONFORMITY BY THE MANUFACTURER

For each type of gas-discharge light source the manufacturer or the holder of the approval mark shall carry out tests, in accordance with the provisions of this Regulation, at appropriate intervals.

2.1.   

Nature of tests

Tests of conformity of these specifications shall cover their photometric, geometrical and optical characteristics.

2.2.   

Methods used in tests

2.2.1.

Tests shall generally be carried out in accordance with the methods set out in this Regulation.

2.2.2.

The application of paragraph 2.2.1 requires regular calibration of test apparatus and its correlation with measurements made by a Competent Authority.

2.3.   

Nature of sampling

Samples of gas-discharge light sources shall be selected at random from the production of a uniform batch. A uniform batch means a set of gas-discharge light sources of the same type, defined according to the production methods of the manufacturer.

2.4.   

Inspected and recorded characteristics

The gas-discharge light sources shall be inspected and test results recorded following the grouping of characteristics as listed in Annex 7, table 1.

2.5.   

Criteria governing acceptability

The manufacturer or the holder of approval is responsible for carrying out a statistical study of the test results in order to meet the specification laid down for verification of conformity of products in paragraph 4.1 of this Regulation.

Compliance shall be assured if the level of acceptable non-compliance per grouping of characteristics given in table 1 of Annex 7 is not exceeded. This means that the number of gas-discharge light sources not complying with the requirement for any grouping of characteristics of any gas-discharge light source type does not exceed the qualifying limits in the relevant tables 2, 3 or 4 of Annex 7.

Note: Each individual gas-discharge light source requirement shall be considered as a characteristic.

ANNEX 7

Sampling and compliance levels for manufacturer’s test records

Table 1

Characteristics

Qualifying limits for acceptance based on different numbers of test results for each grouping of characteristics are listed in table 2 as maximum number of non-compliances. The limits are based on an acceptable level of 1 per cent of non-compliances, assuming an acceptance probability of at least 0,95.

Table 2

Qualifying limits for acceptance based on different numbers of test results for each grouping of characteristics are listed in table 3 given as maximum number of non-compliances. The limits are based on an acceptable level of 6,5 per cent of non-compliances, assuming an acceptance probability of at least 0,95.

Table 3

Qualifying limits for acceptance based on different numbers of test results for each grouping of characteristics are listed in table 4 given as a percentage of the results, assuming an acceptance probability of at least 0,95.

Table 4

(1)  The assessment shall in general cover series production gas-discharge light sources from individual factories. A manufacturer may group together records concerning the same type from several factories, provided these operate under the same quality system and quality management.

ANNEX 8

MINIMUM REQUIREMENTS FOR SAMPLING BY AN INSPECTOR

1.

The conformity requirements shall be considered satisfied from a photometric, geometrical, visual and electrical standpoint if the specified tolerances for production gas-discharge light sources in the relevant data sheet of Annex 1 and the relevant data sheet for the caps are met.

2.

The conformity of mass-produced gas-discharge light sources shall not be contested if the results are in agreement with paragraph 5 of this annex.

3.

Conformity shall be contested and the manufacturer requested to make the production meet the requirements if the results are not in agreement with paragraph 5 of this annex.

4.

If paragraph 3 of this annex is applied, a further sample of 250 gas-discharge light sources, selected at random from a recent production run, shall be taken within two months.

5.

Compliance approved or disapproved shall be decided according to the values in table 1. For each grouping of characteristics gas-discharge light sources shall be either accepted or rejected according to the values in table 1(1).

Table 1

(1)  The proposed scheme is designed to assess the compliance of gas-discharge light sources to an acceptance level of non-compliance of 1 per cent and 6,5 per cent respectively and is based on the Double Sampling Plan for Normal Inspection in IEC Publication 60410: Sampling Plans and Procedures for Inspection by Attributes.

(2)  The gas-discharge light sources shall be inspected and test results recorded following the grouping of characteristics as listed in Annex 7, table 1.
