EN 60432-1:1994

Standard EN 60432-1 specifies the safety and interchangeability requirements of tungsten filament incandescent lamps for general lighting service having: - rated wattage up to and including 200 W; - rated voltage of 50 V to 250 V inclusive. - bulbs of the A, B, C, G, M, P, PS, PAR or R shapes*, or other bulb shapes where the lamps are intended to serve the same purpose as lamps with the foregoing bulb shapes ; - bulbs with all kinds of finishes; - caps B15d, B22d, E14, E27, or E27/51x39. This standard specifies the method a manufacturer should use to show that his product conforms to this standard on the basis of whole production appraisal in association with his test records on finished products. This method can also be applied for certification purposes. Details of a batch test procedure which can be used to make limited assessment of batches are also given. Requirements for batch testing are included in order to enable the assessment of batches presumed to contain unsafe lamps. As some safety requirements cannot be checked by batch testing and as there may be no previous knowledge of the manufacturer's quality, batch testing cannot be used for certification purposes nor in any way for an approval of the batch. Where a batch is found to be acceptable, a testing agency may only conclude that there is no reason to reject the batch on safety grounds. This standard is concerned with safety criteria only and does not take into account the performance of tungsten filament lamps with respect to luminous flux, life or power consumption characteristics. Readers should refer to EN 60064 for such characteristics with respect to types normally used for general lighting service. * See IEC 887 for description of the letter symbols.
