The luminous intensity distribution may be represented by numeri-cal tables or by graphics and is usually expressed in units of candelas per 1 000 lm of lamp flux !3.7 measurement lamp lamp used for the photometric characterisation of a luminaire 3.8 cold spot (of a fluorescent lamp) coldest point on the discharge tube that determine the Hg-pressure in the discharge tube" 4 Co-ordinate system 4.1 General2 The determination of the intensity distribution
involves the use of a co-ordinate system in order to define the di-rection in which the intensity measurements are made; the system used is a spherical co-ordinate system with the centre coincident with the photometric centre of the luminaire. From a general point of view the co-ordinate system consists in a group of planes with a single axis of intersec-tion: the polar axis. In this system a direction in space is characterised by two angles: a)-
the angle between the plane taken as a conventional origin and the half plane containing the considered di-rection; b)
- the angle between the polar axis and the considered direction or the complement of this angle. The orientation of this system with respect to the first axis and the second axis (see Figure 1) of the luminaire is chosen with particular regard to the type of luminaire, to the type of lamp, to the mounting attitude of the luminaire and its application, in order to perform more accurate measurements or to simplify the consequent lighting calcu-lations. The identification of the first axis and the second axis shall be defined by the manufacturer or the photometric laboratory according to this standard. The third axis is the axis containing the photometric centre and perpendicu-lar to the two first axes. For information on the location of the photometric centre see clause 5.8. NOTE Usually the first axis of a luminaire is perpendicular to the light emitting area of the luminaire. As the light emitting area is not always clearly defined and could be curved, the relationship between this axis and a mechanical feature of the lu-minaire should be declared (e.g., the design attitude for road luminaires or the front glass for floodlights and for ceiling mounted luminaires the surface upon which the luminaire is mounted).

Key 1 First axis 2 Second axis 3 Third axis 4 Photometric centre Figure 1 — Photometric centre and photometric axes of the luminaire 4.2 System of measuring planes 4.2.1 General In general the luminous intensity distribution of a luminaire is measured in a number of planes. From the variety of possible measuring planes three systems of planes have been historically used and were identified by the CIE as A-, B- and C-planes.
The same terminology is adopted in this standard, but A-planes system is disregarded. The C-planes system is to be considered as the recommended standard system. The B-planes system may also be used, in particular for the photometry of luminaires such as floodlights. Any two of these planes with an angular difference of 180° will form a plane in the mathematical sense. 4.2.2 B-planes3 The totality of B-planes (see Figure 2) is the group of planes for which the line of intersection (polar axis) goes through the photometric centre and is parallel to the second axis of the luminaire. B-planes are marked with angles Bx with -180° ≤ Bx ≤ +180°. Within a plane directions are given by the angle β with – 90° ≤ β ≤ + 90°. The system of B-planes is coupled rigidly to the light source and follows its tilt if the lumi-naire is tilted. The photometric centre of the luminaire lies in the centre of the co-ordinate system. The first axis of the luminaire lies in plane B0, is perpendicular to the polar axis through the photometric centre and points in the direction β = 0°. The second axis of the luminaire is coincident with the polar axis.

Key 1 First axis, polar axis 2 Second axis 3 Third axis 4 Page = C-plane Figure 3 — Luminaire orientation for C-planes The system of C-planes is oriented rigidly in space and does not follow a tilt of the luminaire. If the luminaire is tilted during measurement (the polar axis is not coincident with the first axis of the luminaire), the angle of tilt should be declared (see Figure 4).

Conventions related to the choice of axes linked to the luminaire: 1) The first axis of the luminaire is the axis through the photometric centre and perpendicular to the plane which is representative of the main light emitting area. 2) For luminaires containing linear single or double ended lamps, the axis of the lamp or the geometric axis of multiple lamps, is chosen as the third axis of the luminaire, perpendicular to the two first ones. It means that the transverse plane to the lamps of the luminaire, which is generally the most extensive light emitting plane, lies in the C=0 plane (for luminaires with a symmetry in this transverse plane in C0 /C180 plane). 3) For luminaires with the lamp axis coincident with the first axis of the luminaire, for luminaires with multiple lamps or for luminaires where no lamp axes can be defined, the luminaire shall be orientated that: a) the maximum intensity Imax of the light distribution is within the C0 plane or if Imax is located at γ = 0° or if there are more than one location of Imax; b) the C0 /C180 plane is the symmetry plane of the luminous intensity distribution with the highest degree of symmetry. If the latest convention 1) or 2) is applicable or if different conventions are used, the choice of luminaires axes shall be stated by the manufacturer or the photometric laboratory, as to clearly identify the luminaire alignment in the co-ordinate system, as well for photometric measurements as for lighting calculations. NOTE For road lighting calculations, the usual convention is that the C0 /C180 intensity planes lie parallel to the road. This is normally the case for most transversely mounted luminaires, but not for luminaires with linear lamp(s) where the lamp axis is parallel to the road axis. 4.2.4 Relationships between the plane systems5 The value of the light intensity measured in a certain direction is independent of the way the direction is pre-sented. Generally the values of each of the two angles are different for any direction in the aforementioned plane systems. The angular values of one plane system can be converted into the corresponding angular values of an-other plane system if the relationships given in the following Table 1 are used. The relationships are only valid if the tilt angle of the luminaire in the C-plane system is zero and as far as the second axis of the luminaire respects the conventions for luminaire orientations in the two co-ordinate systems.

To avoid confusion with the co-ordinate systems originally defined by CIE, A-plane name for this system is not recommended.

5.2.4 Air movement9 The movement of air around the light source under test will reduce the operating temperature, and in consequence the luminous flux of some types of lamps will change.
Such movement of air may be caused by draughts, air con-ditioning or motion of light source in the photometer. The air movement caused by self heating of the light source shall be ignored. Air movement in the vicinity of light sources sensitive to temperature variation shall not exceed 0,2 m/s. NOTE For lamps highly sensitive to temperature variations a smaller value may be necessary. !The provisions of Annex F apply for luminaires equipped with single capped tubular compact fluorescent lamps (TC-F, TC-L and other TC lamps with external ballast), 16 mm diameter linear double-capped fluorescent lamps (T16) and single-ended ring fluorescent lamps (T16-R)." 5.2.5 !!!!Stabilisation"""" of the light source Measurement shall not be started until the light source has stabilised photometrically, see Table 2. At the end of the measurement (and regularly during a long series of tests) a return should be made to the initial position (e.g. 0° in elevation with a goniophotometer) to check that the initial photometric reading is maintained within ± 1 %. For lamp types other than those listed in Table 2 test conditions should be selected to meet the repeatability re-quirements of ± 2 %. 5.3 Electrical power supply10 5.3.1 Current handling capacity The power supply shall be of ample current handling capacity for the loads to be connected.

The value of light output ratio obtained by each of the two methods shall not differ by more than ± 2 %. 5.6 Luminance measurements The following procedures shall be followed when measuring either the average luminance of a luminaire or the lu-minance of a stated luminous patch: 1) The average luminance of the luminaire in a stated direction, or in a series of directions. The luminous intensity shall be measured with a goniophotometer and the luminance shall be calculated by dividing it by the projected luminous area. 2) The luminance of a stated luminous patch in a stated direction (usually part of a scan of the luminaire to find the maximum luminance in a stated direction, the scan may be repeated for other directions). The measure-ments may be made either with a goniophotometer or with a luminance meter. The patch luminance can be measured directly with a luminance meter or with the goniophotometer using an appropriate mask.
If relevant publications do not exist, the lamp(s) shall comply as closely as possible with the nominal specifications of the lamp manufacturer. When testing luminaires and bare lamps the ballasts built into the luminaire shall be used. If the luminaire under test does not have a built in ballast, the ballast type shall be of a type agreed by the luminaire manufacturer and the same ballast shall be used for testing the luminaire and the bare lamps. The luminaire's specification shall be clearly and fully identified. The luminaire shall be mounted according to the manufacturer’s instructions. For surface mounted luminaires, the greater heat retention influence of a longer warm up compared to recessed or pendant mounted luminaires shall be taken into account by attaching the luminaire to a mounting board. The board shall be approximately 15 mm thick and made of wood or wood fibre (or insulating material if required.) It shall be of the same outline as the plan view of the luminaire; m
