TR 62493-1 @ IEC:2013(E) - 11 - A change inthe measurementprocedureinIEC64293isneededto avoid this misinterpretation.The activities to resolve this problem in IEC 62493 have been started. 4.4 Evaluation of the influenceof certain characteristicsof theluminaires The following evaluations show the influence on the EMF results measured according IEC62493 resultingfrom specificcharacteristics of the luminaires. Examples of the to identify construction details of luminaires which are critical for the EMF measurements. All tables are sorted for the average of the measured results (highest average measurement value is on top). Here average means that this is the average of the results of all measured luminaires with the same specification. (Scientific), Inc.. To avoid any deviation caused by the single critical luminaire that showed a huge difference between AC and DC mode, only the DC results of this luminaire have been used in the tables below. In all tables,the columns are structured in the same way as shown in Table1. subscriptions.techstreet.com, d Table1-Structureoftables Column Description Parameter which is varied. This can be the type of the luminaire or some characteristics (e.g. First column material, lamp technology,lamp cover,type of lamp) Number of This column gives the absolute number of samples which have the characteristic given in the samples first column This is the linear average of the measured results (factor F according IEC 62493) during the Average value investigations All values in the tables are sorted in descending order using the values of this column. Max value This gives the maximum value of all measured results (factor F according IEC 62493) in the group of samples 4.5 TypeofluminairesaccordingTableA.1ofIEC62493:2009 Table A.1 of IEC 62493:2009 determines the distance to the test head which is required for measurement. The rowwiththenumber (23)in Table 2is used mostly for luminaires with LEDlampswhich are intended for ceiling and recessed mounting. The standard in its present edition often refers mostly to luminaires with fluorescent lamps in Table A.1 of IEC 62493:2009.Therefore luminaires with LED are mostly in this row.

There was no clear result visible in the table. It is therefore not possible to derive further conclusions regardingthe EMFbehaviourfromthis resultand fromtheluminaireclassification inIEC62493:2009,TableA.1. 4.6 Lamp cover The influence of the lamp cover (luminaire construction: housing and different reflector material) is shown in Table 3.
