"General This International Standard specifies the performance requirements for LED modules@ together with the test methods and conditions@ required to show compliance with this standard. The following types of LED modules are distinguished and schematically shown in Figure 1: Type 1: integrated LED modules for use on d.c. supplies up to 250 V or on a.c. supplies up to 1 000 V at 50 Hz or 60 Hz. Type 2: LED modules operating with part of separate controlgear connected to the mains voltage@ and having further control means inside (""semi-integrated"") for operation under constant voltage@ constant current or constant power. Type 3: LED modules where the complete controlgear is separate from the module (nonintegrated) for operation under constant voltage@ constant current or constant power. The requirements of this standard relate only to type testing. Recommendations for whole product testing or batch testing are under consideration. This standard covers LED modules@ based on inorganic LED technology that produces white light. Life time of LED modules is in most cases much longer than the practical test times. Consequently@ verification of manufacturer's life time claims cannot be made in a sufficiently confident way@ because projecting test data further in time is not standardised. For that reason the acceptance or rejection of a manufacturers life time claim@ past an operational time as stated in 6.1@ is out of the scope of this standard. Instead of life time validation this standard has opted for lumen maintenance codes at a defined finite test time. Therefore@ the code number does not imply a prediction of achievable life time. The categories@ represented by the code@ are lumen-depreciation character categories showing behaviour in agreement with manufacturer's information which is provided before the test is started. In order to validate a life time claim@ an extrapolation of test data is needed. A general method of projecting measurement data beyond limited test time is under consideration. The pass/fail criterion of the life time test as defined in this standard is different from the life time metrics claimed by manufacturers. For explanation of recommended life time metrics@ see Annex C. NOTE When modules are operated in a luminaire@ the claimed performance data can deviate from the values established via this standard due to e.g. luminaire components that impact the performance of the LED module. The separate electronic controlgear for LED modules as mentioned in Type 2 and Type 3 is not part of the testing against the requirements of this standard. Protection for water and dust ingress@ see B.3. Statement It may be expected that integrated LED modules which comply with this standard will start and operate satisfactorily at voltages between 92 % and 106 % of rated supply voltage. LED modules with separate controlgear are expected to start and operate satisfactorily in combination with the specified controlgear complying with IEC 61347-2-13 and IEC 62384. All LED modules are expected to start and operate satisfactorily when operated under the conditions specified by the LED module manufacturer and in a luminaire complying with IEC 60598-1. The requirements for individuals apply for 95 % of the population."
